  • What is a power purchase agreement (PPA)?

    A power purchase agreement (PPA) is a long-term supply contract between an electricity generating company (the seller) and an electricity purchasing business (the buyer). If the PPA is referred to as a renewable or green PPA, the power is generated from renewable energy sources like hydro, solar or wind power with their associated environmental benefits. Renewable or green PPAs enable developers to secure financing for new renewables projects and allow buyers to secure a long-term fixed electricity price while significantly reducing their CO2 emissions.
