Our Project

Project Description

Mayo Renewable Power (MRP) is building a 42.5 MW (net) biomass High Efficiency CHP plant located on the former Asahi site in Killala, Co. Mayo. CHP or Combined Heat & Power is a form of technology whereby both heat and electricity are produced to obtain the maximum energy from the input fuel. In operation, this plant will use wood chip biomass. The fuel will be supplied from a variety of sources including locally grown willow, spruce from local forestry and forestry thinnings along with imported supplies. Adjacent to the power plant will be a biomass fuel storage and processing facility which will supply biomass wood chips for sale to the domestic market. The 42.5MW (net) electricity produced by the plant will be exported directly onto the National Grid and distributed throughout the country. This development will bring jobs to the NW of Mayo, provide a much needed boost to the local economy and deliver significant carbon savings helping Ireland deliver on its renewable energy commitment.
