The remaining 20% stake will be owned by the Anesco management team, led by chief executive Adrian Pike and chief operating officer Tim Payne.

Anesco will offer a variety of products, including property insulation, solar photovoltaics, solar thermal and maintenance of microgeneration installations.

According to SSE, developments such as the ‘Green Deal’, Carbon Reduction Commitment, Feed-in Tariffs and the Renewable Heat Incentive all point to major growth in each of these areas.

SSE said it’s investment in Anesco is similar in scale to that it has made in other new or developing sustainable energy ventures.

SSE energy supply director Alistair Phillips-Davies said that there is likely to be major growth in energy efficiency and low carbon products over the next decade, and SSE retains a direct, active and growing interest in this sector.

"Investing in Anesco provides us with another catalyst for growth in this area, and this blend of direct and indirect participation in these growing markets gives us a strong position for the future," Phillips-Davies said.
