Power Purchase Agreement Ofgem

Power Purchase Agreement (PPA) is a long-term contract between a renewable energy generator and a buyer of electricity. This agreement helps in the procurement of renewable energy by large corporations, government entities, and institutions. The PPA model has gained significant popularity in the UK and other parts of the world, especially after the implementation of Feed-in Tariffs (FiT) and Renewable Obligation Certificates (ROCs) in the energy sector.

Ofgem, the UK`s energy regulator, plays an essential role in the implementation and regulation of PPAs. In recent years, Ofgem has introduced several regulations and guidelines to make PPA contracts more transparent, accessible, and fair for both renewable energy generators and buyers.

One of the critical concerns for renewable energy generators in PPA contracts is the uncertainty in the pricing structure. Ofgem has addressed this issue by introducing the Renewable Energy Guarantees of Origin (REGO) scheme. The REGO scheme ensures that the renewable energy generators receive the full value of their electricity production at a fixed price, irrespective of the wholesale electricity market price fluctuations. This creates a more stable and predictable revenue stream for the renewable energy generators.

Another significant concern for buyers of renewable energy is the creditworthiness of the renewable energy generator. Ofgem has addressed this by introducing the Supplier of Last Resort (SoLR) mechanism. The SoLR mechanism protects the buyers of renewable energy in case the renewable energy generator goes bankrupt. The mechanism ensures that electricity supply is maintained until a new buyer or generator is found. This provides a safety net for the buyers of renewable energy and encourages more corporations and institutions to enter into PPA contracts with renewable energy generators.

The PPAs are regulated by Ofgem under the Balancing and Settlement Code (BSC) and the Grid Code. The BSC sets out the balancing arrangements for electricity in the UK, while the Grid Code sets out the technical and operational requirements for the electricity transmission and distribution system. These regulations ensure that the PPA contracts are adhered to and that the electricity grid remains stable and reliable.

In conclusion, the PPA model has become an effective tool for the procurement of renewable energy in the UK. The role of Ofgem in regulating and supporting the development of PPAs has been critical in ensuring that the contracts are transparent, accessible, and fair for both renewable energy generators and buyers. The introduction of the REGO scheme and the SoLR mechanism provides a stable and predictable revenue stream for renewable energy generators and a safety net for buyers of renewable energy. The PPAs regulated by Ofgem under the BSC and the Grid Code ensure that the electricity grid remains stable and reliable.
