There was a 300 per cent rise in installation of small-scale combined heat and power plants in 2011 according to government figures published last week.
It means an additional one million tonnes of CO2 were saved.
Annual statistics produced by the Department of Energy and Climate Change (DECC) showed that over 300 CHP units were installed last year, with the majority of units in the 30–600 kW category, as used in offices, leisure centres and hotels.
The small-scale CHP sector has been booming over recent years, growing by an average of 20% year-on-year and now representing around 400 MW of capacity.
Overall, CHP now provides 7.5% of the UK’s electricity requirements and saves 14 million tonnes of CO2 per year.
When E.ON’s 1,275 MW Isle of Grain CHP facility is completed later this year, that total will rise by an additional 3 million tonnes.
The statistics also showed a rise in the use of renewable fuels in CHP plant to just over 6%, continuing a trend of the last eight years.
Craig Dennett from the Combined Heat and Power Association said: “The growth in CHP over recent years is a tremendous success story for both the energy sector and the wider economy. This is a UK-based industry that reduces energy bills and carbon emissions from our homes, public buildings, businesses and industry. We have only developed a fraction of the potential for CHP, so there is a huge opportunity for the Government to capitalise on this when it produces policies in support of its Heat Strategy later in the year.”
