In line with the Department for Communities and Local Government’s Planning Policy Statement 22 on Renewable Energy, some 120 local planning authorities have set targets for the use of on-site renewable energy in new developments. As recognised by our Microgeneration Strategy, such policies play an important role in stimulating the renewables industry and create a market for microgeneration technologies. The first authority to formalise the policy was the London borough of Merton. While we have not estimated the monetary value of Merton style policies, I know that the microgeneration business regard them as an important driver for their market.
