A Power Purchase Agreement (PPA) is a long-term contract in which a buyer agrees to purchase electricity from a generator under defined commercial terms. It usually sets the price, volume, delivery point, duration, and settlement rules. In energy project finance, a PPA matters because it turns uncertain future sales into more predictable revenue, which helps lenders and investors assess whether a project is bankable.
From a cyber security perspective, PPAs are important because they depend on accurate contract data, metering records, billing systems, and settlement calculations. If those records are altered, delayed, or made unavailable, payments can be disputed and revenue confidence can collapse. Attackers may target contract repositories, market interfaces, or operational systems to manipulate pricing data or disrupt invoicing. Defenders protect PPAs with strong access control, signed records, audit logs, segregation of duties, and validation of meter and settlement data. In large infrastructure projects, the security of the information behind the contract can be as important as the contract itself.
