Irish power station goes greener

Tubosider’s latest stormwater system for Balfour Beatty Ireland (BBI) is now installed at the Edenderry Power Station, 60km west of Dublin near the heart of Ireland’s peat producing midlands.

The construction of the Biomass Slab was a construct only project for BBI’s client Bord Na Mona and the ultimate end user Edenderry Power. Edenderry is committed to co-firing the peat stations with 30% biomass by 2015.

Working within a live power station, BBI was commissioned to excavate up to 2m of existing peat material and replace with imported granular material, followed by the installation of 12,500m² of concrete storage slab.

The works also included the installation of surface water drainage infrastructure including settlement tanks, silt traps, pumping chamber including associated mechanical and electrical works and oil interceptors.

Designing our attenuation system for the best solution, we produced a 455m³ volume tank made up of three parallel runs of 1400mm helibore steel pipe, elbowed at two points in a run of 100 meters to match the groundworks.

BBI has previously used Tubosider attenuation systems for two phases of its airport development for Dublin Airport Authority, including a massive 15,800 m³ tank installed in 2008 – the largest Tubosider system ever commissioned from outside the UK.

Edenderry Power is Ireland’s first large scale independent power producer and has been in operation since 2000, producing 120MW of electricity to supply around 3% of Ireland’s national requirement.

To reduce greenhouse gas emissions and bring diversity to the fuel mix, Bord na Móna is committed to using 300,000 tonnes per annum of biomass by 2015 at Edenderry (30% co-firing), with up to 500,000 tonnes required there by 2020.

Biomass is organic plant-based material, and represents the world’s fourth largest energy resource after oil, coal and gas. It is typically sourced from forestry and purpose grown energy crops.

It is a sustainable energy resource that will play a major role in reducing Ireland’s CO² emissions. Biomass for Edenderry comes sawmill residues and pulpwood from forestry thinnings, energy crops and agri-residues.
