Our Impact on Ireland’s Energy Goals
With over 15 years of experience in the industry, REIL has been instrumental in managing and delivering Energy Efficiency Obligation Scheme (EEOS) targets on behalf of Obligated Parties in Ireland. Currently, we oversee more than 56% of the EEOS target, contributing significantly to Ireland’s national energy reduction goals for 2030. When combined with the government’s alternative energy initiatives, our work accounts for approximately 39% of the country’s total energy reduction targets.

REIL is the largest supplier of Energy Credits under the EEOS scheme, ensuring that our clients met their energy obligations each year. Our expertise in developing and managing large-scale energy efficiency programmes has positioned us as a trusted leader in the sector, and many of these successful initiatives continue today.
