What Renewable Energy Requirements Exist Under PERMENESDM 50/2017?
1.0 Introduction and Regulatory Context
Indonesia's renewable energy sector operates under a complex regulatory framework designed to balance energy security, economic viability, and environmental sustainability. The Ministry of Energy and Mineral Resources Regulation Number 50 of 2017 (PERMENESDM 50/2017) concerning the Utilization of Renewable Energy Sources for Electricity Supply represents a pivotal component of this framework, establishing comprehensive requirements for renewable energy procurement, pricing mechanisms, and cooperation schemes.
This regulation emerged from Indonesia's commitment to diversifying its energy portfolio and reducing dependence on fossil fuels. The archipelagic nation possesses substantial renewable energy potential estimated at 441.7 Gigawatts (GW) across six primary sources: hydropower, solar, wind, ocean currents, bioenergy, and geothermal energy. Despite this enormous potential, installed renewable energy capacity reached only approximately 9 GW by 2017, representing merely 2% of total potential. This utilization gap underscored the necessity for regulatory intervention to accelerate renewable energy development while maintaining electricity affordability for Indonesian consumers.
PERMENESDM 50/2017 was promulgated on August 8, 2017, replacing its predecessor, PERMENESDM 12/2017, which had been in effect for only seven months before being superseded. The rapid replacement reflected the government's recognition that initial regulatory approaches required substantial refinement to achieve optimal renewable energy deployment. The regulation has subsequently been amended twice: first by PERMENESDM 53/2018 and second by PERMENESDM 4/2020, demonstrating ongoing regulatory adaptation to evolving sector dynamics.
The regulation's primary objectives encompass several interrelated goals. First, it seeks to establish clear, transparent mechanisms for PT Perusahaan Listrik Negara (Persero) (PLN), Indonesia's state electricity company, to procure electricity generated from renewable energy sources. Second, it aims to create pricing structures that balance investor returns with consumer affordability, addressing previous criticisms that renewable energy tariffs were economically prohibitive. Third, it standardizes cooperation frameworks between PLN and independent power producers (IPPs) developing renewable energy projects.
Understanding PERMENESDM 50/2017 requires examining its position within Indonesia's broader legal hierarchy. The regulation derives authority from Law Number 30 of 2007 concerning Energy, which establishes national energy policy principles, and Law Number 30 of 2009 concerning Electricity, which governs electricity supply business activities. Presidential Regulation Number 22 of 2017 concerning the General National Energy Plan (RUEN) provides strategic direction, establishing targets for renewable energy contribution to the national energy mix. PERMENESDM 50/2017 translates these higher-level legal mandates into operational requirements applicable to specific renewable energy projects.
The regulation applies to various stakeholders within Indonesia's electricity sector. PLN, as the primary off-taker of renewable energy-generated electricity, bears significant obligations under the regulation regarding procurement procedures and tariff implementation. Independent power producers planning to develop renewable energy projects must comply with technical specifications, licensing requirements, and contractual frameworks established by the regulation. The Ministry of Energy and Mineral Resources retains regulatory oversight, particularly regarding tariff approvals and direct appointment mechanisms. Regional governments also play roles in certain renewable energy categories, particularly waste-to-energy facilities and hydropower projects utilizing irrigation infrastructure.
The scope of renewable energy technologies covered by PERMENESDM 50/2017 is comprehensive. The regulation specifically addresses hydropower facilities of various scales, solar photovoltaic installations, wind power systems, biomass-fueled generators, biogas facilities, ocean energy converters, marine current generators, and waste-to-energy plants. Each technology category is subject to differentiated treatment regarding procurement procedures, pricing formulas, and technical requirements, reflecting the distinct characteristics and development challenges associated with each renewable energy source.
This Regulatory Matrix Analysis (RMA) provides systematic examination of PERMENESDM 50/2017's provisions, focusing on definitional frameworks, procurement mechanisms, pricing formulas, cooperation schemes, and implementation requirements. The analysis incorporates amendments introduced through PERMENESDM 53/2018 and PERMENESDM 4/2020, presenting the current consolidated regulatory framework applicable to renewable energy electricity procurement in Indonesia.
The regulation's significance extends beyond technical legal compliance. It represents Indonesia's policy approach to renewable energy transition, balancing aspirational clean energy targets with pragmatic economic constraints. The pricing mechanisms established under the regulation directly influence renewable energy investment decisions, determining project financial viability across different Indonesian regions. Procurement procedures shape market access for domestic and foreign investors, affecting competitive dynamics within the renewable energy sector. Understanding these regulatory provisions is therefore essential for stakeholders navigating Indonesia's renewable energy landscape.
2.0 Key Definitions and Scope
2.1 Regulatory Definitions Framework
PERMENESDM 50/2017 establishes definitional parameters that structure its entire regulatory framework. While complete verbatim text of all definitions from Article 1 is not publicly accessible in digital format, the regulation's implementation reveals several critical definitional categories that govern its application.
Renewable Energy Sources (Sumber Energi Terbarukan) constitute the regulation's primary subject matter. The regulation recognizes multiple renewable energy categories, each with distinct characteristics affecting procurement and pricing treatment. These sources include:
Hydropower (Energi Air) encompasses electricity generation from flowing water, covering facilities ranging from micro-hydro installations (below 100 kW) to large-scale hydroelectric dams exceeding 10 MW capacity. The regulation differentiates between run-of-river systems, reservoir-based facilities, and pumped-storage installations. Notably, the 2020 amendment introduced specific provisions for hydropower facilities utilizing dams or irrigation channels constructed by the Ministry of Public Works and Public Housing.
Solar Energy (Energi Surya) primarily addresses photovoltaic technology converting sunlight directly into electricity. The regulation focuses on solar PV installations rather than concentrated solar thermal systems, reflecting Indonesia's equatorial solar resource characteristics. Both ground-mounted and rooftop configurations fall within the regulatory scope, subject to different technical and commercial considerations.
Wind Energy (Energi Angin or Energi Bayu) covers electricity generation from wind turbines, applicable to both onshore and offshore installations. Indonesia's wind resources, while less abundant than in temperate regions, support viable projects in specific geographic areas, particularly in eastern Indonesia and certain coastal locations.
Bioenergy encompasses multiple subcategories. Biomass (Biomassa) refers to organic matter derived from agricultural residues, forestry waste, or dedicated energy crops, converted to electricity through combustion or gasification processes. Biogas (Biogas) involves electricity generation from anaerobic digestion of organic materials, producing methane-rich gas subsequently burned in generators. The regulation treats these bioenergy categories distinctly in pricing formulas.
Ocean Energy includes multiple technologies harnessing marine resources. Tidal energy, wave energy, and ocean thermal energy conversion systems all fall within this category, though commercial deployment in Indonesia remains limited during the regulation's effective period.
Geothermal Energy (Panas Bumi) represents a significant renewable resource given Indonesia's position along the Pacific Ring of Fire. The regulation addresses geothermal electricity generation, though comprehensive geothermal regulation primarily exists in separate legal instruments, particularly Law Number 21 of 2014 concerning Geothermal Energy.
Waste-to-Energy (Energi Sampah) facilities, formalized as PLTSa (Pembangkit Listrik Tenaga Sampah), convert municipal solid waste into electricity through incineration or gasification technologies. The regulation provides specialized treatment for these facilities, recognizing their dual function in electricity generation and waste management.
Electricity Purchase Agreements constitute the contractual framework through which PLN procures renewable energy-generated electricity. The regulation establishes specific parameters for these agreements, including duration, pricing mechanisms, payment terms, and performance obligations.
Base Cost of Generation (Biaya Pokok Penyediaan Pembangkitan or BPP) represents a critical pricing benchmark. BPP refers to PLN's average cost of generating electricity in a specific regional electricity system or nationally. This metric directly influences renewable energy tariff calculations, as discussed subsequently.
Regional Electricity Systems divide Indonesia's electricity infrastructure into distinct operational zones. The regulation differentiates treatment between major interconnected systems (Sumatra, Java-Bali, and certain other grids) and isolated systems in remote areas, recognizing different economic conditions and generation costs across regions.
2.2 Scope and Application
PERMENESDM 50/2017 applies to electricity procurement relationships between PLN and renewable energy generators. The regulation governs:
First, renewable energy facilities connecting to PLN's distribution or transmission systems for purposes of selling generated electricity. This includes both dedicated independent power producers developing projects specifically for PLN offtake and captive power facilities with excess generation available for sale.
Second, electricity procurement procedures PLN must follow when acquiring renewable energy-generated power. The regulation mandates specific processes depending on project characteristics, procurement circumstances, and renewable energy technology types.
Third, tariff determination methodologies for renewable energy electricity purchases. The regulation establishes formulas, benchmarks, and approval procedures governing pricing between PLN and renewable energy generators.
Fourth, cooperation scheme frameworks structuring legal and commercial relationships between PLN and project developers. The regulation originally mandated Build-Own-Operate-Transfer (BOOT) models for most renewable energy categories but subsequently eliminated this requirement through the 2020 amendment.
The regulation explicitly excludes certain categories from its scope. Renewable energy facilities developed exclusively for captive consumption without grid connection fall outside regulatory requirements. Small-scale rooftop solar installations eligible for net-metering arrangements under separate regulations are not subject to PERMENESDM 50/2017 procurement procedures. Geothermal projects, while technically renewable energy, primarily operate under specialized geothermal regulations rather than this ministerial regulation's general provisions.
Matrix 1: Renewable Energy Technology Categories and Definitional Characteristics
| Technology Category | Indonesian Term | Technical Characteristics | Regulatory Treatment | Scale Range |
|---|---|---|---|---|
| Hydropower | PLTA (Pembangkit Listrik Tenaga Air) | Electricity from flowing water via turbines | 100% BPP tariff cap in high-cost regions; BOO cooperation scheme allowed | Micro (<100kW) to Large (>10MW) |
| Solar Photovoltaic | PLTS (Pembangkit Listrik Tenaga Surya) | Direct solar-to-electricity conversion via PV cells | 85% BPP tariff cap in high-cost regions; subject to competitive bidding | Residential (<10kW) to Utility-scale (>1MW) |
| Wind Power | PLTB (Pembangkit Listrik Tenaga Bayu) | Wind turbine electricity generation | 85% BPP tariff cap in high-cost regions; limited deployment to date | Small (<100kW) to Commercial (>1MW) |
| Biomass | PLTBm (Pembangkit Listrik Tenaga Biomassa) | Combustion/gasification of organic matter | 85% BPP tariff cap in high-cost regions; agricultural integration common | Small (<1MW) to Medium (10MW+) |
| Biogas | PLTBg (Pembangkit Listrik Tenaga Biogas) | Anaermic digestion gas-to-electricity | 85% BPP tariff cap in high-cost regions; waste integration potential | Micro (<100kW) to Small (1MW) |
| Ocean Energy | PLTA Laut (Pembangkit Listrik Tenaga Air Laut) | Tidal, wave, or ocean thermal systems | 85% BPP tariff cap; minimal commercial deployment | Pilot to Commercial (1-10MW) |
| Geothermal | PLTP (Pembangkit Listrik Tenaga Panas Bumi) | Steam from underground heat reservoirs | 100% BPP tariff cap; separate regulatory framework | Medium (20MW) to Large (100MW+) |
| Waste-to-Energy | PLTSa (Pembangkit Listrik Tenaga Sampah) | Municipal solid waste incineration/gasification | 85% BPP tariff cap; ministerial assignment procurement | Small (1MW) to Medium (10MW) |
2.3 Jurisdictional and Geographic Application
PERMENESDM 50/2017 applies throughout Indonesian territory, covering all provinces and administrative regions. However, the regulation's practical implementation varies significantly across geographic zones due to differentiated electricity market conditions.
The regulation distinguishes between "high BPP regions" and "low BPP regions," creating different pricing dynamics. High BPP regions typically include remote areas with isolated electricity grids, small generation capacity, heavy diesel fuel dependence, and expensive logistics. These regions, particularly in eastern Indonesia and remote islands, experience BPP levels exceeding the national average, triggering the regulation's preferential tariff formulas.
Conversely, low BPP regions encompass areas with interconnected grids, diverse generation portfolios, economies of scale, and access to affordable fuel sources. Java, Bali, and parts of Sumatra generally constitute low BPP regions where renewable energy tariffs face more stringent economic scrutiny.
This geographic differentiation reflects Indonesia's archipelagic geography and uneven electricity infrastructure development, creating context-specific renewable energy economics across different provinces.
3.0 Core Requirements and Provisions
3.1 Electricity Procurement Mechanisms
PERMENESDM 50/2017 establishes multiple pathways through which PLN procures renewable energy-generated electricity, reflecting diverse project characteristics and development contexts.
Competitive Bidding (Tender) constitutes the primary procurement mechanism for most renewable energy projects. This process involves PLN issuing solicitations specifying technical requirements, capacity needs, commercial terms, and evaluation criteria. Interested developers submit proposals competing on price, technical capability, financial strength, and project timelines. PLN evaluates submissions and selects winning bidders based on predetermined criteria, subsequently negotiating detailed Power Purchase Agreements with selected developers.
Competitive bidding aims to achieve cost efficiency through market competition, encouraging developers to offer attractive tariffs while maintaining project viability. The process provides transparency in procurement decisions and facilitates participation by multiple qualified developers. However, tender processes can involve extended timelines, substantial transaction costs for participants, and complexity requiring sophisticated commercial and technical expertise.
Direct Appointment (Penunjukan Langsung) provides an alternative procurement pathway under specific circumstances. The original PERMENESDM 50/2017 version limited direct appointment availability, but the 2020 amendment through PERMENESDM 4/2020 substantially expanded permissible direct appointment scenarios, recognizing that competitive bidding may not suit all renewable energy development contexts.
Article 4 of the amended regulation authorizes direct appointment under several conditions:
Emergency electricity supply situations (Keadaan Darurat Penyediaan Listrik) permit direct appointment when regional electricity systems face critical supply shortfalls requiring rapid capacity additions. The emergency circumstance must be formally declared, and selected projects must demonstrate capability for expedited deployment addressing the supply crisis.
Excess power availability allows direct appointment when existing facilities possess surplus generation capacity available for PLN purchase. This scenario typically applies to industrial captive power plants with renewable energy components capable of selling excess production without requiring new facility construction.
Generation capacity expansion at existing renewable energy facilities qualifies for direct appointment when projects involve adding generating units or upgrading existing infrastructure rather than developing entirely new installations. This provision recognizes that incumbent operators possess site-specific advantages making competitive reselection inefficient.
Single qualified provider situations permit direct appointment when only one entity possesses necessary licenses, land rights, resource access, or technical capabilities for a specific renewable energy project. This commonly applies to hydropower projects where geographic and water resource constraints limit potential developers.
Hydropower facilities with prior location permits obtain direct appointment eligibility when projects have secured location permits (izin lokasi) from regional governments before the regulation's effective date. This provision protects developers who initiated permitting processes under previous regulatory frameworks.
Ministerial Assignment (Penugasan Menteri) represents a third procurement mechanism involving direct government instruction to PLN to purchase electricity from specific renewable energy projects. This mechanism applies to particular project categories where policy considerations transcend pure commercial criteria.
The 2020 amendment introduced Article 7A establishing ministerial assignment for hydropower facilities utilizing dams or irrigation channels constructed by the Ministry of Public Works and Public Housing. These infrastructure projects possess primary functions in water management, flood control, or agricultural irrigation, with electricity generation constituting a secondary benefit. Ministerial assignment ensures these facilities' electricity output integrates into the grid without requiring developers to navigate competitive procurement processes.
Similarly, Article 10(3) mandates ministerial assignment for waste-to-energy plants (PLTSa), with project selection conducted by regional governments according to waste management regulations. This procurement pathway recognizes that waste-to-energy facilities serve dual public purposes—electricity generation and municipal waste disposal—justifying specialized procurement treatment.
Article 18B, added through the 2020 amendment, establishes ministerial assignment for renewable energy projects funded through foreign grants or government sources outside the Ministry of Energy and Mineral Resources' budget. This provision accommodates international development assistance programs and inter-ministerial initiatives supporting renewable energy deployment.
3.2 Pricing and Tariff Structures
PERMENESDM 50/2017's pricing framework represents its most commercially significant component, directly affecting renewable energy project economics and investment decisions. The regulation establishes differentiated tariff formulas based on technology type and regional BPP characteristics.
Technology Category 1: Solar PV, Wind, Biomass, Biogas, and Ocean Energy
For solar photovoltaic, wind power, biomass, biogas, and ocean energy facilities, the regulation applies an 85% BPP ceiling in high-cost regions:
When regional BPP exceeds national average BPP: Maximum purchase price equals 85% of regional BPP for PLN's generation facilities. This formula provides renewable energy developers with bankable tariffs in high-cost electricity systems while ensuring renewable energy remains cheaper than PLN's conventional generation. For example, if PLN's diesel generators in a remote island system have BPP of 2,000 IDR/kWh, renewable energy maximum tariff reaches 1,700 IDR/kWh (85% × 2,000).
When regional BPP equals or is below national average BPP: Pricing is determined through negotiation (business-to-business) between PLN and the developer. No regulatory ceiling applies, but market dynamics and PLN's economic constraints practically limit achievable tariffs. In Java-Bali's low-cost system, for instance, solar PV projects must offer competitive prices reflecting that system's favorable generation economics.
This differentiated approach recognizes that renewable energy becomes economically attractive in high-cost diesel-dependent systems where 85% of BPP still provides viable returns, while requiring market-based pricing in efficient grid systems where renewable energy must compete with affordable conventional generation.
Technology Category 2: Hydropower, Waste-to-Energy, and Geothermal
For hydropower facilities, waste-to-energy plants, and geothermal projects, the regulation provides more favorable 100% BPP ceilings:
When regional BPP exceeds national average BPP: Maximum purchase price equals 100% of regional BPP. Using the previous example, if regional BPP is 2,000 IDR/kWh, hydropower maximum tariff reaches the full 2,000 IDR/kWh. This premium reflects these technologies' distinct characteristics—hydropower's baseload capability and long operational life, waste-to-energy's environmental co-benefits, and geothermal's strategic importance for Indonesia's volcanic energy resources.
When regional BPP equals or is below national average BPP in Sumatra, Java, Bali, or similar systems: Pricing is determined through business-to-business negotiation without regulatory ceilings, similar to Category 1 technologies. However, the regulation's legislative history indicates more favorable treatment for these technologies in government policy priorities.
BPP Calculation and Application
Regional BPP represents PLN's average generation cost per kilowatt-hour in a specific electricity system, encompassing fuel costs, operations and maintenance, capital depreciation, and financing costs for PLN's own generation assets. The Ministry of Energy and Mineral Resources periodically publishes official BPP figures for different regional systems, providing transparent benchmarks for tariff calculations.
National average BPP aggregates costs across Indonesia's entire electricity system, weighted by generation volume. This metric serves as the threshold determining whether regional systems qualify for percentage-of-BPP tariff formulas or default to negotiated pricing.
The regulation requires all agreed tariffs to receive ministerial approval before implementation, providing regulatory oversight ensuring pricing aligns with national energy policy objectives and consumer affordability considerations.
Matrix 2: Procurement Mechanisms and Applicable Conditions
| Procurement Method | Regulatory Basis | Applicable Scenarios | Process Characteristics | Approval Requirements |
|---|---|---|---|---|
| Competitive Bidding (Tender) | Article 4 (default mechanism) | General renewable energy projects without special circumstances | PLN issues public solicitation; developers submit competing proposals; evaluation based on technical and commercial criteria; contract negotiation with winner(s) | Ministerial approval of final tariff required |
| Direct Appointment - Emergency Supply | Article 4 (PERMENESDM 4/2020) | Formally declared electricity supply emergencies requiring rapid capacity additions | Single developer selected based on capability for immediate deployment; abbreviated procurement timeline | Ministerial approval of emergency declaration and tariff |
| Direct Appointment - Excess Power | Article 4 (PERMENESDM 4/2020) | Existing facilities with surplus renewable generation capacity available for sale | Negotiation with facility operator; no competitive process required | Ministerial tariff approval |
| Direct Appointment - Capacity Expansion | Article 4 (PERMENESDM 4/2020) | Expansion of existing renewable energy facilities adding generation units | Incumbent operator selected for expansion; no recompetition | Ministerial approval of expansion terms |
| Direct Appointment - Single Provider | Article 4 (PERMENESDM 4/2020) | Projects where only one entity holds necessary licenses, permits, or resource access rights | Direct negotiation with sole qualified developer | Ministerial approval confirming single provider status |
| Direct Appointment - Prior Location Permit | Article 4 (PERMENESDM 4/2020) | Hydropower projects with regional government location permits predating regulation | Protection of developers with prior permitting progress | Ministerial approval validating permit status |
| Ministerial Assignment - PUPR Hydro | Article 7A (PERMENESDM 4/2020) | Hydropower utilizing dams/irrigation infrastructure built by Ministry of Public Works and Public Housing | Ministry of ESDM assigns PLN to purchase power; no competitive process | Ministerial assignment letter; tariff approval |
| Ministerial Assignment - Waste-to-Energy | Article 10(3) (original regulation) | Municipal waste-to-energy facilities selected by regional governments under waste management regulations | Regional government designates developer; Ministry assigns PLN purchase obligation | Ministerial assignment letter; tariff approval |
| Ministerial Assignment - Foreign Grant Projects | Article 18B (PERMENESDM 4/2020) | Projects funded by foreign grants or non-ESDM government funding sources | Ministry assigns PLN to offtake power from grant-funded project | Ministerial assignment letter; tariff approval |
3.3 Cooperation Schemes and Contractual Frameworks
PERMENESDM 50/2017 originally mandated Build-Own-Operate-Transfer (BOOT) as the primary cooperation scheme for renewable energy projects. Under BOOT arrangements, private developers finance, construct, own, operate, and maintain generation facilities for a specified concession period (typically 20-30 years), selling electricity to PLN throughout this period. Upon concession expiration, facility ownership transfers to PLN without additional compensation.
BOOT schemes provided PLN with long-term asset acquisition while enabling private sector project development and operation during economically productive periods. However, the model faced criticism from investors concerned about asset transfer requirements potentially reducing project valuations and financing attractiveness.
The 2020 amendment through PERMENESDM 4/2020 substantially reformed cooperation scheme requirements. Article 27B eliminated the mandatory BOOT requirement for renewable energy projects, allowing developers and PLN to negotiate alternative arrangements. Build-Own-Operate (BOO) schemes, where developers retain permanent ownership without eventual transfer to PLN, became permissible, providing greater flexibility in structuring commercial relationships.
Existing projects operating under BOOT contracts received options to restructure agreements converting to BOO frameworks, subject to mutual agreement between PLN and developers. This regulatory change reflected recognition that ownership transfer requirements could unnecessarily constrain renewable energy investment, particularly for technologies with long operational lives extending beyond typical concession periods.
Waste-to-energy facilities (PLTSa) received exemption from BOOT requirements even under the original regulation, recognizing these facilities' integration with municipal waste management systems and distinct operational characteristics compared to pure electricity generation projects.
Power Purchase Agreements (PPAs) between PLN and renewable energy developers must incorporate specific elements mandated by the regulation, including capacity specifications, energy delivery obligations, tariff structures and adjustment mechanisms, performance guarantees and penalties, force majeure provisions, dispute resolution procedures, and contract duration terms.
The regulation establishes minimum contract durations sufficient to support project financing, typically ranging from 20 to 30 years depending on technology type and project scale. These extended tenors provide revenue stability necessary for developers to secure long-term project finance from commercial lenders and development finance institutions.
4.0 Implementation Framework
4.1 Administrative Procedures and Licensing
Renewable energy developers must navigate multi-layered permitting and approval processes to implement projects under PERMENESDM 50/2017's framework. While the regulation itself focuses on PLN procurement procedures and tariff structures, successful project development requires obtaining numerous complementary authorizations.
Business Licensing constitutes the foundational requirement. Developers must obtain Electricity Supply Business Permits (Izin Usaha Penyediaan Tenaga Listrik or IUPTL) from the Ministry of Energy and Mineral Resources or, for smaller-scale facilities, from provincial governments under decentralized authority. The 2020 Omnibus Law (Law 11/2020 concerning Job Creation) and its implementing regulations substantially reformed business licensing procedures, introducing the Risk-Based Licensing (Perizinan Berusaha Berbasis Risiko) system and Online Single Submission (OSS) platform consolidating multiple permits.
Environmental Permitting requires developers to complete Environmental Impact Assessment (AMDAL) processes for large-scale projects or Environmental Management and Monitoring Plans (UKL-UPL) for smaller facilities. These environmental instruments assess potential ecological impacts, propose mitigation measures, and establish monitoring protocols. Environmental permits are issued by Ministry of Environment and Forestry or regional environmental agencies depending on project scale and location.
Land Rights and Spatial Planning Compliance necessitate securing land tenure for project sites through purchase, long-term lease, or land use rights (Hak Guna Usaha or Hak Guna Bangunan). Projects must comply with regional spatial plans (Rencana Tata Ruang Wilayah) and obtain location permits or spatial conformity statements confirming alignment with designated land use zones.
Technical and Safety Certifications require facilities to meet Indonesian National Standards (Standar Nasional Indonesia or SNI) for electrical equipment, grid connection specifications, and safety protocols. The Ministry of Energy and Mineral Resources' Directorate General of Electricity establishes technical requirements for grid interconnection, including voltage standards, power quality specifications, and protection systems.
Grid Connection Agreements complement Power Purchase Agreements, establishing technical terms for physical interconnection between renewable energy facilities and PLN's transmission or distribution networks. These agreements address connection point specifications, metering arrangements, dispatch protocols, and operational coordination procedures.
Financial and Tax Considerations include securing project financing from commercial banks, development finance institutions, or capital markets. Renewable energy projects may access fiscal incentives under Indonesia's investment regulations, including tax holidays (Pajak Penghasilan or income tax holidays for qualifying sectors), import duty exemptions for capital equipment, and accelerated depreciation allowances. The regulation's tariff approval requirement ensures project economics align with these financial structures.
4.2 Tariff Approval Process
All renewable energy electricity purchase prices, regardless of procurement method, require approval from the Minister of Energy and Mineral Resources before implementation. This approval process serves multiple policy functions: ensuring tariffs align with consumer affordability objectives, verifying calculation methodology compliance with regulatory formulas, confirming pricing consistency with national energy policy priorities, and providing transparency in public utility cost structures.
Developers and PLN jointly submit tariff approval requests to the Directorate General of Electricity, accompanied by supporting documentation including detailed cost analyses, financial models demonstrating project viability, BPP calculations justifying proposed tariffs, and draft Power Purchase Agreements incorporating the proposed pricing. The Ministry reviews submissions for regulatory compliance, economic reasonableness, and policy alignment, potentially requesting additional information or modifications before granting approval.
Approval timelines vary based on project complexity and Ministry workload, ranging from several weeks for straightforward cases to several months for complex projects requiring extensive review. Developers typically initiate approval processes concurrently with PPA negotiations to minimize project timeline delays.
Matrix 3: Technology-Specific Tariff Formulas and Application Conditions
| Technology Type | Indonesian Acronym | High BPP Region Tariff Formula (Regional BPP > National Average) | Low BPP Region Tariff Formula (Regional BPP ≤ National Average) | Policy Rationale |
|---|---|---|---|---|
| Solar Photovoltaic | PLTS Fotovoltaik | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Competitive technology requiring cost discipline; viable in high-cost systems |
| Wind Power | PLTB | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Intermittent generation requiring economic competitiveness |
| Biomass | PLTBm | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Agricultural integration and rural development benefits within economic constraints |
| Biogas | PLTBg | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Waste valorization and small-scale distributed generation |
| Ocean Energy | PLTA Laut | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Emerging technology with limited commercial deployment |
| Hydropower | PLTA | Maximum 100% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Baseload capability; strategic importance; long operational life |
| Waste-to-Energy | PLTSa | Maximum 85% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Dual environmental benefits (waste management + energy); regional government role |
| Geothermal | PLTP | Maximum 100% × Regional BPP | Business-to-business negotiation (no regulatory ceiling) | Strategic national resource; baseload generation; volcanic geography advantages |
Note: Regional BPP refers to Base Cost of Generation for PLN's facilities in the specific electricity system; National Average BPP represents aggregate BPP across Indonesia's entire grid system
4.3 Performance Obligations and Compliance
Renewable energy facilities operating under PPAs with PLN bear performance obligations ensuring reliable electricity supply consistent with agreed technical and commercial parameters. While specific performance requirements vary by technology and individual PPA terms, common obligations include:
Capacity Availability requires facilities to maintain generating capacity at or above contracted levels, accounting for reasonable maintenance outages and force majeure events. Underperformance relative to guaranteed availability metrics may trigger financial penalties or tariff adjustments.
Energy Delivery obligations specify minimum annual energy production targets, particularly relevant for technologies with capacity factors significantly below 100% (such as solar and wind). Facilities must demonstrate good faith operational practices maximizing generation within resource availability constraints.
Grid Code Compliance mandates adherence to technical standards governing power quality, frequency regulation, voltage control, and reactive power support. Modern renewable energy facilities, particularly larger installations, must incorporate technical capabilities supporting grid stability and system reliability.
Metering and Reporting requires accurate measurement of generated electricity delivered to PLN, typically through independently certified metering equipment with data provision to both parties. Periodic reporting on facility operations, maintenance activities, and performance metrics provides transparency and enables regulatory oversight.
Maintenance and Asset Management obligations ensure facilities remain in good working condition throughout PPA tenors, maintaining performance capabilities and safety standards. Planned outages require advance notification and coordination with PLN's system operations to minimize grid disruption.
Financial Security may include performance bonds, parent company guarantees, or other credit support mechanisms ensuring developer financial capacity to fulfill PPA obligations. These securities protect PLN against developer default or project abandonment.
Failure to meet performance obligations can result in various consequences including financial penalties proportionate to performance shortfalls, tariff reductions reflecting reduced capacity value, PPA termination rights in cases of persistent material breaches, and potential license revocation by regulatory authorities for severe compliance failures.
Conversely, PLN bears reciprocal obligations under PPAs, including accepting delivered electricity up to contracted capacity, making timely payments according to agreed schedules, maintaining grid infrastructure enabling reliable power evacuation, and coordinating dispatch and curtailment decisions consistent with system operations needs.
5.0 Practical Implications and Strategic Considerations
5.1 Investment Decision Framework
PERMENESDM 50/2017's provisions directly shape renewable energy investment economics in Indonesia, creating differentiated opportunity landscapes across technologies and geographic locations.
High BPP Region Opportunities present the most economically favorable contexts for renewable energy development under the regulation's tariff formulas. Remote island systems, isolated regional grids, and diesel-dependent electricity networks typically exhibit BPP levels ranging from 1,500 to 3,000 IDR/kWh or higher, substantially exceeding national average BPP around 1,000-1,200 IDR/kWh. In these contexts:
Solar PV projects achieving 85% of regional BPP can secure tariffs of 1,275-2,550 IDR/kWh, providing attractive returns even for higher-cost distributed installations. Islands in Maluku, Papua, and eastern Nusa Tenggara represent prime markets under this tariff structure.
Hydropower facilities obtaining 100% of regional BPP access tariffs matching PLN's conventional generation costs, creating compelling economics for mini-hydro and small hydro projects in mountainous regions of Sulawesi, Kalimantan, and Sumatra.
Wind power developments in favorable resource areas, particularly coastal sites and specific inland corridors, become financially viable at 85% BPP levels in high-cost systems, though Indonesia's relatively modest wind resources require careful site selection.
Biomass and biogas facilities integrated with agricultural operations (palm oil mills, rice processing, livestock farming) can achieve economic viability in high BPP regions while creating synergistic value streams from waste valorization and energy sales.
Low BPP Region Challenges create more competitive environments where renewable energy must demonstrate cost-competitiveness with efficient conventional generation. Java-Bali's interconnected grid benefits from diverse generation including large coal plants, combined-cycle gas turbines, and existing hydropower, producing BPP around 800-1,000 IDR/kWh. In this context:
Renewable energy tariffs must compete through business-to-business negotiation without regulatory price floors, requiring projects to achieve low levelized costs of energy (LCOE) through favorable resource conditions, efficient technology, optimized financing, and economies of scale.
Utility-scale solar PV farms in high-irradiance areas, particularly in eastern Java and southern Sumatra, can potentially offer competitive prices around 800-1,000 IDR/kWh with favorable debt financing and tax incentives.
Large geothermal projects, despite 100% BPP eligibility in high-cost regions, must demonstrate economic competitiveness in Java-Bali where negotiated pricing applies, though government policy support for geothermal development provides some preferential treatment.
Technology Selection Considerations require developers to assess technology-specific tariff treatment, resource availability, and deployment complexity:
Hydropower's 100% BPP ceiling in high-cost regions provides tariff advantages over solar and wind (85% BPP), making hydro particularly attractive where suitable sites exist. However, hydropower development involves complex permitting (water rights, environmental impacts, resettlement considerations) and long development timelines potentially offsetting tariff benefits.
Solar PV's rapid deployment capability, modular scalability, and declining capital costs partially offset the 85% BPP ceiling disadvantage compared to hydro. Projects can achieve commercial operation within 12-18 months versus 3-5+ years for hydropower, accelerating revenue generation.
Waste-to-energy projects benefit from specialized procurement through regional government designation and ministerial assignment, potentially reducing competitive pressure. However, these projects face complex technical challenges in feedstock management, emissions control, and integration with municipal waste systems.
5.2 Regional Government and Stakeholder Roles
PERMENESDM 50/2017's implementation involves multiple governmental and private sector actors whose coordination determines successful renewable energy deployment.
Regional Government Functions extend beyond traditional administrative roles in several specific contexts:
Waste-to-energy projects require regional government (provincial or municipal) designation of developers according to waste management regulations before ministerial assignment of PLN purchase obligations. Regional governments therefore serve as gatekeepers determining which developers access PLTSa opportunities in their jurisdictions.
Hydropower facilities utilizing irrigation infrastructure built by regional governments may require regional approval or coordination for electricity generation integration, particularly where water resource management priorities must balance irrigation, flood control, and power generation objectives.
Location permits (izin lokasi) and spatial planning conformity determinations remain regional government responsibilities, providing provinces and districts with influence over renewable energy facility siting even where technical licensing resides at national level.
PLN's Institutional Position combines commercial purchaser and regulated utility functions, creating complex incentive structures affecting renewable energy procurement. As Indonesia's dominant electricity buyer, PLN determines practical market access for most renewable energy projects. The regulation's tariff formulas constrain PLN's pricing negotiations in high BPP regions but allow substantial discretion in low BPP areas where business-to-business negotiation applies.
PLN faces financial pressures balancing renewable energy purchases against corporate profitability and government-mandated electricity tariffs for consumers. Higher renewable energy procurement costs must be absorbed within PLN's overall cost structure, potentially creating institutional resistance to expensive renewable energy additions despite regulatory mandates.
The state-owned enterprise also bears grid integration responsibilities, requiring investment in transmission infrastructure, system balancing capabilities, and dispatch management accommodating variable renewable energy (particularly solar and wind). These integration costs, not directly addressed in PERMENESDM 50/2017, affect PLN's renewable energy procurement enthusiasm.
Private Sector Developer Landscape encompasses diverse actors from large multinational energy companies and regional Indonesian conglomerates to specialized renewable energy developers and independent power producers. Each actor category brings distinct capabilities, risk tolerances, and strategic objectives:
International developers typically pursue larger-scale projects (50-100+ MW) offering substantial returns justifying international deployment costs. These actors bring advanced technical capabilities, established financing relationships, and portfolio diversification strategies but may require higher return thresholds than domestic developers.
Domestic Indonesian companies possess local market knowledge, political relationships, and potentially lower cost structures but may face capital constraints limiting project scale and financial engineering sophistication. Partnerships between international and Indonesian developers frequently emerge to combine complementary strengths.

5.3 Emerging Trends and Future Regulatory Directions
The renewable energy regulatory landscape in Indonesia continues evolving, with several trends likely to influence future amendments to PERMENESDM 50/2017 or development of complementary regulations.
Technology Cost Reductions in solar PV, wind power, and battery storage are rapidly changing renewable energy economics. Global learning curves and manufacturing scale effects have driven solar module costs down by over 90% since 2010, with similar trends in wind turbines and lithium-ion batteries. These cost reductions suggest that competitive renewable energy tariffs in low BPP regions will become increasingly feasible even without percentage-of-BPP premium formulas.
Indonesia's renewable energy policy may evolve toward auction-based procurement mechanisms emphasizing cost discovery and competitive price formation rather than formula-based tariff ceilings. Several Southeast Asian countries have successfully implemented competitive auctions achieving renewable energy tariffs below conventional generation costs, providing models potentially applicable to Indonesia's market.
Grid Integration Challenges from variable renewable energy (VRE) sources will likely intensify as solar and wind deployment scales increase. Unlike dispatchable hydropower or geothermal facilities providing consistent baseload generation, solar PV and wind power exhibit output variability based on weather conditions and diurnal/seasonal patterns. System operators must manage this variability through forecasting, flexible conventional generation, energy storage, demand response, and grid interconnection.
Future regulatory development may address VRE integration through requirements for renewable energy facilities to provide ancillary services (frequency regulation, voltage support, ramp rate control), incentive structures for energy storage paired with VRE generation, curtailment protocols and compensation mechanisms when grid conditions cannot accommodate renewable energy output, and power quality standards and penalties ensuring grid stability.
Distributed Generation and Prosumer Models are expanding beyond traditional centralized renewable energy facilities selling exclusively to PLN. Rooftop solar installations, microgrids, and hybrid renewable energy systems serving local loads with excess sales to PLN represent growing market segments. Current regulations addressing these distributed models (particularly MEMR Regulation 26/2021 on rooftop solar) complement PERMENESDM 50/2017, but regulatory harmonization challenges persist.
Future frameworks may need to address net metering or net billing arrangements for distributed generation, feed-in tariffs for small-scale renewable energy systems, virtual power plant aggregation models, and peer-to-peer energy trading platforms potentially emerging as blockchain and digital technologies mature.
Climate Finance and Carbon Markets are creating new value streams potentially complementing electricity sales revenues for renewable energy projects. Indonesia's commitment to carbon emissions reductions under the Paris Agreement, development of domestic carbon pricing mechanisms, and access to international climate finance (Green Climate Fund, bilateral development assistance, carbon credits) may provide additional project revenue or capital sources.
Regulatory frameworks may evolve to clarify carbon credit ownership and monetization for renewable energy projects, integrate carbon pricing into electricity tariff structures, facilitate international climate finance access for Indonesian renewable energy developers, and establish monitoring, reporting, and verification protocols for emissions reductions claims.
Just Transition Considerations will become increasingly prominent as renewable energy deployment potentially affects communities dependent on fossil fuel industries. Coal mining regions in Kalimantan and Sumatra, as well as workers in coal-fired power generation, face economic disruption as Indonesia transitions toward cleaner energy sources. Policy frameworks addressing workforce retraining, regional economic diversification, and equitable distribution of renewable energy benefits will likely complement technical procurement regulations.
5.4 Compliance Verification and Enforcement
PERMENESDM 50/2017's effectiveness depends on robust compliance monitoring and enforcement mechanisms ensuring stakeholders adhere to regulatory requirements.
Ministerial Oversight occurs through multiple channels. The Directorate General of Electricity within the Ministry of Energy and Mineral Resources monitors PLN's procurement activities, reviews tariff approval requests and supporting documentation, investigates stakeholder complaints regarding regulatory violations, and conducts periodic assessments of renewable energy deployment progress against national targets.
Non-compliance consequences can include rejection of tariff approval applications requiring developers and PLN to renegotiate pricing, invalidation of improperly procured PPAs necessitating re-procurement through correct procedures, financial penalties on PLN for procurement violations, and license sanctions on developers failing to meet performance obligations.
Public Accountability Mechanisms provide transparency in renewable energy procurement. Tariff approval decisions become public records accessible through freedom of information requests or regulatory disclosures. Stakeholder consultations during regulatory amendments allow industry participants, civil society organizations, and affected communities to provide input on regulatory effectiveness and needed reforms.
PPA Dispute Resolution provisions address conflicts between PLN and renewable energy developers regarding contract interpretation, performance obligations, or payment disputes. PPAs typically establish tiered dispute resolution beginning with negotiation and escalating through mediation, arbitration (domestic or international), and potentially litigation in Indonesian courts.
The regulatory framework's stability and predictability significantly affect investor confidence and financing availability for renewable energy projects. Frequent regulatory changes, inconsistent enforcement, or unpredictable tariff approvals create investment risks potentially offsetting economic incentives from favorable tariff formulas.
Conclusion
PERMENESDM 50/2017, as amended by PERMENESDM 53/2018 and PERMENESDM 4/2020, establishes Indonesia's comprehensive regulatory framework governing renewable energy utilization for electricity supply. The regulation balances multiple policy objectives: accelerating renewable energy deployment toward national targets, maintaining electricity affordability for Indonesian consumers, ensuring PLN's financial sustainability, and creating investible frameworks attracting private capital to renewable energy development.
The regulation's differentiated approach—applying distinct tariff formulas based on technology type and regional economic conditions, providing multiple procurement pathways accommodating diverse project contexts, and eliminating mandatory BOOT cooperation schemes—reflects sophisticated understanding of renewable energy development complexities and stakeholder needs.
For developers, the regulation creates clearest opportunities in high BPP regions where percentage-of-BPP tariff ceilings provide bankable revenues exceeding costs for properly designed and executed projects. Technologies receiving 100% BPP treatment (hydropower, waste-to-energy, geothermal) possess regulatory advantages over 85% BPP technologies (solar, wind, biomass, biogas, ocean energy), though project-specific factors including resource quality, development costs, and permitting complexity ultimately determine economic viability.
Low BPP regions, particularly Java-Bali's interconnected grid, require renewable energy projects to demonstrate cost-competitiveness through business-to-business negotiation, challenging developers to achieve low levelized costs through technological efficiency, scale economies, and favorable financing. As global renewable energy costs continue declining, competitive opportunities in these markets will likely expand.
PLN's position as dominant electricity purchaser creates procurement dynamics where regulatory compliance, commercial negotiation, and institutional relationships converge. Understanding PLN's constraints, priorities, and operational requirements enhances developers' abilities to structure attractive project proposals and navigate procurement processes successfully.
Regional governments exercise influence through waste-to-energy developer designation, location permitting, and spatial planning determinations, requiring developers to engage effectively with provincial and municipal authorities beyond national-level regulatory compliance.
The regulatory framework continues evolving through periodic amendments responding to technological change, market developments, and policy priorities. Stakeholders must monitor regulatory updates, participate in consultation processes, and adapt strategies to changing requirements.
Ultimately, PERMENESDM 50/2017 represents Indonesia's attempt to create enabling conditions for renewable energy transition while managing complex economic, political, and technical constraints. The regulation's success will be measured by renewable energy deployment rates, tariff affordability, investor participation levels, and contribution to Indonesia's climate commitments and energy security objectives. Understanding its provisions provides essential foundation for effective participation in Indonesia's renewable energy sector.
Regulatory Status Note: This analysis addresses PERMENESDM 50/2017 as the replacement for the originally requested PERMENESDM 12/2017, which was revoked on August 8, 2017, after only seven months of operation. PERMENESDM 50/2017, as subsequently amended by PERMENESDM 53/2018 and PERMENESDM 4/2020, constitutes the current applicable regulation governing renewable energy utilization for electricity supply in Indonesia as of the analysis date.
