The transition to clean energy is no longer merely an environmental agenda; it has evolved into a global business strategy. Companies across industries are facing increasing pressure to reduce carbon emissions, from regulators, investors, and consumers alike. In this context, Indonesia, as a country endowed with vast renewable energy potential, has begun aligning its energy policies to accelerate decarbonization through a range of legal and economic instruments.

One instrument that has gained significant traction is the Power Purchase Agreement (PPA). This mechanism not only serves as the backbone of renewable energy project financing but has also developed into a strategic tool for corporations seeking to fulfill their Environmental, Social, and Governance (ESG) commitments. However, alongside these opportunities, PPAs entail legal complexities and commercial risks that require careful consideration.

Corporate PPA Trends and the Clean Energy Transition

With the growing awareness of climate change, the PPA landscape has undergone a notable shift, from being traditionally dominated by utility providers (such as PLN) to the emergence of corporate PPAs, where companies directly procure electricity from renewable energy developers.

This trend is evidenced by the dominance of major global corporations such as Amazon, Meta, Google, and Microsoft, which collectively accounted for approximately 49% of global corporate PPA transactions in 2025. Corporate procurement of renewable energy through PPAs has become a key driver in expanding global renewable energy capacity and accelerating the development of new energy projects.

Furthermore, this shift is fueled by rapidly increasing energy demand, particularly from data centers and artificial intelligence (AI)-driven technologies. In this regard, corporate PPAs function not only as procurement mechanisms but also as strategic instruments for price risk mitigation and long-term energy supply certainty.

In Indonesia, this trend is gradually emerging alongside growing ESG awareness among corporations. Although structural constraints within the national electricity system remain, current policy directions indicate a promising outlook for the future development of corporate PPAs.

Regulatory Framework for Electricity Sale and Purchase in Indonesia

From a legal perspective, the sale and purchase of electricity—forming the basis of PPAs—is governed by several key regulations, including Law No. 30 of 2009 on Electricity (the “Electricity Law”) and its implementing regulations, such as Presidential Regulation No. 112 of 2022 on the Acceleration of Renewable Energy Development for Electricity Supply.

A key provision is set out in Article 34 of the Electricity Law, as amended by Law No. 6 of 2023 (the “Job Creation Law”), which stipulates that electricity tariffs are determined by the central or regional government, taking into account the balance of national and regional interests, consumer protection, and the interests of licensed electricity suppliers. This indicates that electricity pricing structures are not entirely market-driven but must align with national tariff policies.

Further, under the latest technical regulation, Minister of Energy and Mineral Resources Regulation No. 5 of 2025 on Guidelines for Power Purchase Agreements from Renewable Energy Power Plants, Article 5(1) provides that electricity sale and purchase agreements (PJBL), which in practice constitute PPAs, may be executed for a maximum term of up to 30 years from the Commercial Operation Date (COD), with the possibility of extension without recalculating the initial investment costs.

This provision is particularly significant as it provides long-term certainty for investors. Given the capital-intensive nature of renewable energy projects, contract duration is a critical factor in determining financial viability. The longer the PPA term, the greater the likelihood of achieving an optimal return on investment.

Overall, Indonesia’s regulatory framework provides a relatively robust legal foundation for PPA implementation, particularly in terms of tariff certainty and contractual tenure.

Conventional PPAs vs. Renewable Energy PPAs

Conceptually, there are fundamental differences between conventional PPAs and renewable energy PPAs.

Conventional PPAs typically involve electricity generated from fossil fuel-based power plants. Their primary characteristic is supply reliability (dispatchability), although they are highly dependent on volatile fuel prices. The key risks in such arrangements include energy price fluctuations and increasing regulatory pressure related to carbon emissions.

In contrast, renewable energy PPAs exhibit distinct characteristics. Energy sources such as solar and wind are inherently intermittent, resulting in variable electricity generation. However, their primary advantage lies in low operational costs and independence from fuel price volatility. The cost structure is heavily weighted toward upfront capital investment, necessitating long-term contractual arrangements to ensure investment recovery.

Moreover, renewable energy PPAs are often aligned with sustainability objectives, including carbon emission reduction and ESG target achievement. As such, they function not only as economic instruments but also as strategic tools in the broader energy transition.

Why PPAs Are Vital for Energy Projects

PPAs play a pivotal role in ensuring the bankability and overall success of energy projects, particularly in the renewable sector. One of their primary functions is to provide long-term revenue certainty for developers. Without guaranteed offtake arrangements, securing financing from financial institutions would be significantly more challenging.

In practice, PPAs are key documents in project financing structures. Lenders rely on these agreements to assess project feasibility, as they reflect the stability of future cash flows. With pre-agreed pricing mechanisms and clearly defined contract durations, investment risks can be substantially mitigated.

Additionally, PPAs serve as effective risk allocation instruments. Risks such as demand fluctuations, regulatory changes, and operational disruptions can be contractually addressed through specific clauses. As such, PPAs not only govern commercial transactions but also function as comprehensive risk mitigation frameworks.

From a commercial standpoint, PPAs offer strategic benefits to both parties. For developers, they ensure long-term revenue streams and form the basis for securing financing. For offtakers, PPAs provide electricity price stability, protection against market volatility, and tangible contributions toward achieving net zero emission targets through renewable energy utilization. Notably, offtakers are not burdened with substantial upfront capital expenditure, as the development and operation of power plants are typically undertaken by third parties.

Nevertheless, PPAs also present certain challenges. Their complexity and long-term nature require thorough legal and technical due diligence. There are performance risks if power generation does not meet projected outputs, as well as potential regulatory risks arising from policy changes that may impact project continuity. Credit risk is also a critical consideration, particularly where one party lacks sufficient financial capacity to fulfill its obligations.

Ultimately, a PPA is not merely a contract for the sale and purchase of electricity, but a strategic instrument that bridges business, investment, and sustainability objectives. With a comprehensive understanding of its structure, benefits, and risks, corporations can effectively leverage PPAs to secure energy supply, manage costs, and strengthen their commitment to the clean energy transition. In an evolving regulatory and market landscape, a prudent, risk-based approach is essential to ensure that PPAs deliver sustainable long-term value.***
