A dairy in the west of Ireland opened its own biomass plant this week to cuts its fuel costs by two thirds.
The €5.25 million (£4.3m) biomass facility in County Roscommon will use 30,000 tonnes of woodchip each year.
It is expected to cut heavy fuel oil consumption by more than 70% and carbon emissions by 50%.
The owner, farming group Aurivo, said the facility will recoup the set up costs in energy savings within five years.
Chief Executive Aaron Forde said: “With the heavy burden of energy costs impacting business performance across Ireland, the facility opening today greatly helps Aurivo on its path to sustained international growth.”
Opening this month, the power plant will become a combined heat and power (CHP) plant. By 2016 Aurivo plans to sell energy to the national electricity grid.
