Legal Considerations for Drafting Solar Power Purchase Agreements (PPAs)

Solar power purchase agreements in India are becoming crucial for sustainable energy. These contracts allow for the purchase of power generated by solar energy projects, providing a stable and predictable source of renewable energy. In this context, understanding the legal considerations involved in drafting such agreements is essential to ensure compliance, mitigate risks and foster long-term collaboration between parties.

Solar power purchase agreements in India are pivotal in facilitating renewable energy projects in India. Understanding the intricacies of these agreements is essential for ensuring that they are legally sound and beneficial for all parties involved. Here, we delve into the definition, purpose, and types of PPAs from a legal perspective.

A solar power purchase agreement in India is a legally binding contract between a power generator, typically a solar energy developer, and a power purchaser, which can be a utility, a corporation, or a government entity. The agreement outlines the terms under which the purchaser will buy electricity generated by the solar project. The primary purpose of a PPA is to provide a long-term commitment that assures the generator of a steady revenue stream, while the purchaser benefits from predictable energy costs and compliance with renewable energy mandates.

In an on-site PPA, the solar panels are installed on the purchaser’s property. The energy generated is consumed directly by the purchaser.

The seller (developer) is responsible for the installation, operation, and maintenance of the solar equipment. Key legal elements include site lease agreements, maintenance obligations, and insurance requirements. These agreements must comply with local land use regulations and building codes​.

In off-site PPAs, the energy is generated at a different location but delivered to the purchaser through the grid.

These agreements involve wheeling charges, grid access rights, and energy transmission regulations. Ensuring compliance with state and national grid codes is critical. Off-site PPAs must also address the potential risks of transmission losses and grid unavailability.

VPPAs are financial contracts where the purchaser does not take physical delivery of electricity but buys renewable energy certificates (RECs) and settles financial differences based on market prices.

VPPAs require meticulous drafting of terms related to price hedging, REC ownership, and compliance with renewable energy standards. The financial nature of these agreements means they must also comply with financial regulations and reporting requirements.

Each type of PPA offers unique benefits and legal challenges. On-site PPAs provide direct energy cost savings and regulatory compliance benefits but require careful site and equipment management. Off-site PPAs offer flexibility and scalability for larger projects, making them suitable for companies with multiple locations. VPPAs provide financial benefits and flexibility in meeting renewable energy goals without the need for on-site infrastructure, but they demand rigorous financial management and risk assessment.

This act governs the generation, distribution, transmission, and trading of electricity in India. It allows for the de-licensing of power generation and promotes competition in the electricity sector.

These certificates are part of India’s Renewable Purchase Obligation (RPO) policy, which mandates that a certain percentage of electricity consumed by obligated entities must come from renewable sources. PPAs, especially virtual PPAs (VPPAs), often involve the transfer of RECs to meet these obligations​.

This clause details the duration of the PPA, the capacity of the solar plant, and the obligations of the generator to provide electricity according to agreed standards. It should also outline the responsibilities for the design, construction, operation, and maintenance of the solar facility.

The PPA must specify the pricing mechanism, typically consisting of an availability price and an output price. The availability price covers the fixed costs of making the plant available to generate power, while the output price is based on the actual electricity delivered. This structure is essential for determining the project’s commercial feasibility and bankability.

This clause should include provisions for maintaining the plant’s performance, such as efficiency targets and penalties for non-performance. It ensures that the generator meets the required standards throughout the contract term.

Assessing the creditworthiness of the parties involved is crucial. The generator must ensure that the purchaser has a solid financial standing to meet payment obligations, while the purchaser must verify the generator’s capability to deliver consistent power.

Changes in laws and regulations can impact the PPA. Including a change in law clause allows the parties to adjust the contract terms in response to new regulations, ensuring that the project remains viable despite legal changes​.

Fluctuations in electricity prices can affect the economic balance of the PPA. Hedging strategies and fixed-price agreements can help manage this risk. VPPAs are particularly useful in managing market risks as they allow for financial settlements based on market prices.

Including clauses for arbitration and mediation helps resolve disputes amicably and efficiently without resorting to litigation. These clauses should specify the governing law, the location of arbitration, and the rules to be followed.

Clearly defining the jurisdiction for legal proceedings ensures that any disputes are handled in a preferred legal framework, providing clarity and reducing the potential for jurisdictional conflicts​.
