Figures from the Department of Energy and Climate Change (DECC) have revealed a sharp increase in electricity generated from municipal solid waste combustion and anaerobic digestion.
DECC’s quarterly figures show an increase of over 31% for both energy production methods compared to the same period in 2011.
Municipal solid waste combustion generated 453GWh in the second quarter of 2012, compared to 344GWh the previous year.
Anaerobic digestion (AD) generated 69GWh in the second quarter of 2012, compared with 53GWh the previous year.
Overall generation from bioenergy – including landfill gas, biomass, AD and waste incineration – increased by 6.5% over the previous year, from 2.9TWh to 3.1TWh.
Bioenergy was shown to have the largest share of energy generation from renewable sources.
The report also revealed the number of ROCs issued to accredited generators in 2011/12 increased by 38% to 34.5 million. This equates to an increase of 33% in electricity generation, from 23,249GWh in 2010/11 to 30,819GWh in 2011/12.
Charlotte Morton, chief executive at the Anarobic Digestion and Biogas Association said the statistics show AD has a higher load factor - a measure of productivity - than any other renewable technology.
“This shows the strategic value that biogas has in balancing intermittent generation from other generators.
“The pace of project development is much slower than it could be though – AD’s true potential could see an 800% increase in generation by 2020, if Government offers stable support and adopts policies which ensure feedstock is available, for example by banning biodegradable waste from landfill.”
