Wat is het verschil tussen een EPC- en een PPA-contract voor zonne-energie?

A Power Purchase Agreement (PPA) is a contractual agreement between a power producer and a buyer. The buyer agrees to purchase electricity generated by a renewable energy project for a specified period, typically 10 to 25 years. Engineering, Procurement and Construction (EPC) contracts are agreements where a power producer is responsible for all activities from design, procurement, construction and handing over the finished installation to the end user who is the owner and buyer. PPA: involves financial commitments to the purchase of electricity over the contracted period. EPC: involves financial commitments for the construction and commissioning of the project. PPA: Shifts operational risks to the developer, while the buyer commits to a long term purchase of electricity. EPC: The operational risk also falls on the developer but the fluctuation of the project cost falls on the buyer. PPA: Focuses on revenue generation from selling electricity for the power producer. EPC: Focus on the revenue gained from building, installing and selling the facility as a whole for the power producer.
