The board was responsible in the 1970s for pursuing the policy of developing a nuclear power station, which was to be located at Carnsore Point, County Wexford.
This policy ultimately failed and the board gradually faded from public attention, eventually concentrating on nuclear-related environmental reports.
In 1975 Bord Gáis was established in order to develop Kinsale gas field, slowing the nuclear energy project as it was hoped it may be an alternative.
Friends of the Earth and other groups lobbied against the plan and in 1981 the Electricity Supply Board and the government announced it was no longer national policy.
The board sponsored a number of reports, in particular on the Sellafield plant which has long been a source of dispute between Ireland and the United Kingdom.
