The company BEAL SA is a joint venture of HELECTOR SA. with the Australian company Energy Developments Ltd with each participating in the share capital by 50%. The power plant was implemented in two phases. The first phase (Station I) was implemented in 2001 and consists of 11 DEUTZ TBG620 V16 landfill gas engines with electrical power 1.26 MW each, while the second phase (Station II) started its operation in 2006 consisting of 4 landfill gas engines INNIO Jenbacher JGC620, 2.7 MW each. The total licensed production capacity amounts to 24.22 MW. The plant utilizes up to 15,000 m3/h of landfill gas produced by the landfill cells of OEDA West Attica in which the company has deployed a vertical suction as well as a horizontal transferal network to the Station. The annual electricity production amounts up to 180,000 MWh depending on landfill gas availability. In this way, the emission up to 800,000 tons of CO₂ annually is avoided, making a significant contribution to the environmental footprint of the national target. At the same time, 4.5 MW_th of the rejected Station’s II thermal energy are used to fuel the evaporators of the adjacent Leachate Treatment Plant further preventing the consumption of significant amounts of fossil fuels, while part of the of Station’s I thermal energy is used for district heating of the internal building needs.

The operation of the Station as well as the construction and tuning of relevant landfill networks is done exclusively by HELECTOR’s SA personnel.
