As businesses and organizations continue to explore ways to reduce their carbon footprint and embrace renewable energy, power purchase agreements (PPAs) have emerged as a popular choice for procuring electricity from renewable sources. In this article, we`ll take a closer look at what a PPA is and what it typically includes.

What is a Power Purchase Agreement?

A Power Purchase Agreement (PPA) is a legal contract between an electricity generator (often a renewable energy company) and a buyer (usually a business or organization). The contract outlines the terms under which the buyer will purchase electricity from the generator over a fixed period of time, typically between 10 and 25 years.

PPAs are commonly used by companies and organizations looking to reduce their carbon footprint, meet sustainability goals, and secure long-term energy pricing stability. By entering into a PPA, the buyer agrees to purchase the electricity generated by the provider at a predetermined rate, which can be lower than the current market rate for electricity.

What Does a PPA Look Like?

A PPA is a complex legal document that outlines the terms of the agreement between the buyer and the generator. While the specific details of each PPA will vary depending on the parties involved, there are several common elements that most PPAs include:

Term: The term of the PPA typically ranges from 10 to 25 years, though shorter or longer terms may be negotiated. The term usually corresponds to the expected life of the renewable energy project.

Pricing: The PPA will outline the pricing structure for the electricity, typically based on a fixed price or a variable price with a floor and a ceiling. The pricing structure may be influenced by factors such as the cost of construction, financing, and operation of the renewable energy project.

Delivery: The PPA will specify how and where the electricity will be delivered from the generator to the buyer. This may include the construction of new transmission lines or the use of existing infrastructure.

Responsibilities: The PPA will define the responsibilities of each party, including the generator`s obligation to supply the contracted amount of electricity and the buyer`s obligation to purchase that electricity.

Force Majeure: The PPA will outline the consequences of unforeseeable events that may impact the project`s ability to deliver electricity, such as natural disasters or regulatory changes.

In addition to these core elements, PPAs may also include provisions for project development, insurance, and dispute resolution. Because a PPA is a legally binding contract, it is important for both parties to have a clear understanding of the terms and implications of the agreement.


Power Purchase Agreements provide a mutually beneficial relationship for both the electricity generator and the buyer. By agreeing to purchase electricity from renewable sources at a fixed or variable rate, the buyer is able to meet sustainability goals, reduce their carbon footprint, and lock in long-term energy pricing stability. Meanwhile, the generator is able to secure long-term revenue and financing for renewable energy projects. While PPAs are a complex legal document, their popularity continues to grow as more businesses and organizations explore the benefits of renewable energy.
