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.
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.
