Power Purchase Agreement Alberta

Power Purchase Agreement Alberta: What You Need to Know

A power purchase agreement (PPA) is an agreement between a power producer and a power purchaser whereby the producer agrees to sell electricity to the purchaser for a set price, typically over a period of several years. PPAs are becoming increasingly popular in Alberta due to the province`s rapidly growing renewable energy sector. In this article, we`ll take a closer look at power purchase agreements in Alberta and what you need to know before entering into one.

Overview of Power Purchase Agreements in Alberta

In Alberta, the current electricity market is deregulated, which means that power producers can sell electricity to purchasers at market rates. PPAs are typically entered into between a renewable energy project developer and the Alberta Electric System Operator (AESO), which is responsible for the management of the province`s electricity market.

PPAs can be beneficial for both parties involved. For the power producer, a long-term agreement guarantees a stable revenue stream, which can be crucial for financing the project. For the purchaser, a PPA can provide price certainty and a long-term electricity supply.

Types of Power Purchase Agreements

There are two types of PPAs: fixed and indexed. A fixed PPA sets a specific price for electricity for the duration of the agreement, while an indexed PPA is tied to a benchmark, such as the Consumer Price Index (CPI), and the price of electricity fluctuates accordingly.

In Alberta, most PPAs are indexed, as this allows for some flexibility in pricing while still providing some level of price certainty. The indexed PPA price is typically set at a small premium over the spot market price of electricity, which provides a predictable and stable price for the producer while still allowing for some price fluctuation.

What to Consider Before Entering into a Power Purchase Agreement

Before entering into a PPA, there are a number of factors that should be considered. These include:

– Project feasibility: Before entering into a PPA, the renewable energy project must be thoroughly evaluated to ensure that it is financially feasible and has the potential to generate a stable revenue stream.

– Energy market conditions: It is important to consider the current state of the energy market and anticipate how it may change in the future. This can impact the pricing and terms of the PPA.

– Contract terms: Careful consideration should be given to the terms and length of the PPA, as well as the pricing mechanism used.

– Regulatory environment: The regulatory environment in Alberta can impact the viability of renewable energy projects and the ability to secure a PPA. It is important to work with experienced professionals to navigate the legal and regulatory landscape.


Power purchase agreements are an important part of the renewable energy sector in Alberta. By providing a stable revenue stream for renewable energy projects, PPAs can help drive the growth of the industry while also providing price certainty for electricity purchasers. However, before entering into a PPA, it is important to carefully evaluate the project, energy market conditions, contract terms, and regulatory environment to ensure that the agreement is financially feasible and beneficial for all parties involved.
