Great Britain

Large-scale power plants in the United Kingdom must survive without state feed-in tariffs, and the sector is currently exhibiting very strong growth, particularly due to "green certificates", which the government expanded to include the solar sector in 2012. Utilities and companies consuming large amounts of energy are required by the government to supply/consume a specific proportion of renewable electricity in line with "Renewable Obligation Certificates" (ROCs).

Operates of solar systems receive 1.4 ROCs for each megawatt hour of renewable energy, which they can sell along with the generated solar electricity at a fixed price in accordance with "Power Purchase Agreements" (PPAs) to local energy providers.
