Power Purchase Agreement (PPA)

Term: 3–15 years

Fixed price

100% green energy with Guarantees of Origin

A Power Purchase Agreement (PPA) is a long-term contract between a business and a renewable energy producer that defines the price and terms for electricity supply. It removes exposure to market volatility and establishes a stable, sustainable framework for buying and selling enery, tailored to the specific needs of both parties.

The benefits of a PPA for your business

Stability

Lock in a fixed electricity price that’s fully independent of market fluctuations. This ensures predictable long-term budgeting and reduces financial risk.

Sustainability

Each PPA is signed with a renewable energy producer and includes the Guarantees of Origin issued by the national energy agency. This strengthens your ESG performance and supports the growth of the renewable energy sector.

Financial efficiency

Contract terms are tailored to your business needs, with pricing that’s more competitive than standard market levels.
