Deputy Prime Minister Nick Clegg is poised to announce which energy efficiency fund managers have been picked to run £100m-worth of government funds.
Equitix and SDCL will be taken on to manage the money, which is set to invest in small-scale projects to make commercial buildings greener.
Clegg will also unveil several smaller coups for the British energy sector, including Close Loop Recycling’s £12m expansion in Dagenham and a new UK headquarters for Power Electronics.
The government is grappling with a major reform of the energy market, which has caused controversy over its preference for gas, and the loss in March of a £15bn investment in nuclear power by E.ON and RWE.
Energy secretary Ed Davey, a Liberal Democrat, will say the coalition “is taking the necessary steps to develop a secure, clean energy mix”.
The government today hosts a meeting of energy leaders as part of its international business summit linked to the Olympics.
