Power Purchase Agreement (PPA)

A PPA is a long-term contract to buy electricity directly from a power generator at a fixed price.

Definition

A Power Purchase Agreement (PPA) is a long-term contract (typically 10-25 years) between a power generator and a buyer (utility, corporation, or datacenter) to purchase electricity at a pre-agreed price. PPAs are critical for financing renewable energy projects because they provide revenue certainty. For datacenters, PPAs enable: (1) Long-term renewable energy supply at fixed costs, (2) Hedge against electricity price volatility, (3) Additionality — funding new renewable capacity. Harch Corp uses solar and wind PPAs to power its datacenters with 100% renewable energy.
