Biomass at Edenderry Power station

Peat & Biomass

With increased use of biomass at Edenderry Power station the amount of renewable electricity (RES-E) generated has increased steadily over the period from 14,900 MWh in 2008 to 84,800 MWh in 2010.

Edenderry Power – commissioned in 2000, Edenderry Power station is a 128 MW (gross) baseload plant – it consumes just over 1 million tonnes (7.7PJ ) of fuel each year – the station uses modern bubbling fluidised bed boiler capacity, which allows a multi-fuel capability. Cofiring at Edenderry Co-firing with biomass at Edenderry The station is capable of burning a wide range of ‘clean’ biomass materials. These include: – woody materials from Irish forests, which may be supplied directly by forestry contractors or indirectly as residues from sawmills – purpose grown energy crops such as willow or Miscanthus – dry materials such as wood pellets or imported agro-industrial residues such as palm kernel or almond shells The co-firing of biomass with peat commenced in 2008, with over 19,000 energy tonnes (ET) of peat displaced in the first year, and the co-firing rate has increased year-on-year as illustrated in the table on the right:

Year Peat Displaced (ET) RES-E Produced (MWh) CO2 Abated (tonnes)
2008 19,100 14,900 16,800
2009 66,600 52,000 58,600
2010 110,800 84,800 95,843

When coupled with the output from the Bellacorick wind farm, Bord na Móna Powergen generated almost of 93,000 MWh of green electricity in 2010. This represented a RES-E rate of 13.2%, and was sufficient to power 18,500 homes.

Co-firing into the future:

Biomass use in Edenderry station will increase from 110,800 tonnes in 2010 to approximately 300,000 energy tonnes, or 30% of the fuel used, by 2015 and to c. 50% or higher by 2020.
