About Us

At ESB, we have been Ireland's foremost energy company since our establishment in 1927. We are driven to make a difference by achieving zero carbon emissions by 2040. Our commitment to providing clean, affordable and reliable energy directly supports the achievement of UN Sustainable Development Goals 7, 9 and 16.

We are a strong, diversified utility operating right across the electricity market: from generation, through transmission and distribution, to supply. We also work in other related sectors where we can make a difference, including telecommunications, electric vehicle charging, home retrofits and more.
