We also provide an overview of connections per county…
The Shannon Scheme connected the first towns from 1929 while the Rural Electrification Scheme connected the last rural area in 1964. The original scheme ended in 1964 but was extended, to allow people who missed out the first time around a chance to reapply for a subsidised connection, through various subsequent phases until 1978.
Note:
‘Year’ refers to the year the location was connected to the national grid.
*A Rural Electrification area consisted of one or more rural parishes and covered about 25 sq miles.

We’ve included information about the islands even though most of them were not connected to the grid until well after the 1970s. More about the islands here.

1927-1945: Ardnacrusha, Shannon Scheme, World War II

In 1929 ESB began supplying the cities, towns and villages with electricity generated at Ardnacrusha and transmitted through the new national Shannon Scheme network.
ESB acquired Pigeon House, an oil burning station previously managed by Dublin Corporation Lighting Committee and Cork Station previously managed by by The Cork Electric Tramways and Lighting Company.
In 1931 a small fuel station with a 300 KW capacity was erected at Letterkenny. As the national network had not yet reached Donegal, it was considered more economic to erect this station.
World War IIÂ delayed plans for other hydro schemes but the Liffey Scheme began generating electricity in 1943.
1946-1964 : Rural Electrification, Hydro and Turf Programmes

The immediate postwar era was concerned with recovery from the setbacks of war. In 1946 the Rural Electrification Scheme began connecting rural homes located beyond the towns and villages. By 1964 ESB had connected over 300,000 homes and businesses in all of its 792 rural areas.
As Ireland sought to become self sufficient and reduce the balance of payments deficit ESB developed turf and hydro programmes. The Turf Programme saw ESB open 10 turf stations in this period. By the 1960s turf accounted for one third of national electricity output.
There was further harnessing of Irish rivers for hydro electricity on the Lee and Erne . Two new large steam stations were opened in Marina in Cork and Ringsend in Dublin.
1965-1979: World Oil Crisis, Turlough Hill, One Million Connections

1973 saw a dramatic upheaval in the world energy scene due to the oil crisis. In 1974 ESB opened its innovative hydro pumped storage station at Turlough Hill.
New large steam stations opened at Great Island, Tarbert and Poolbeg. In 1978 ESB began using natural gas, taken from the nearby Kinsale offshore gas field, as an energy source in the Marina station in Cork.
The Rural Electrification Scheme was extended following amendments to the Electricity Supply Act. This allowed homes, who missed out first time around, another chance to get connected on a subsidised basis. All 792 areas were systematically revisited and the scheme continued through various phases until 1978 when 99% of the country was electrified and our one millionth customer was connected.

Well done ESB, a great achievement. This incredible task was completed by sheer commitment, brains and outstanding manual labour. There was no fancy diggers or hydraulic lifting gear or four wheel drive transporters in those times. The company currently responsible for the roll out of broadband to all areas would do well to study how spectacularly the ESB changed for good the lives of everybody on this island.
Well done, any info on the Galway Electric company in your archive?
I recently visited Ardnacrusha and was very impressed by the way you are preserving our industrial heritage. Congratulations.
Hi Jean, thanks for getting in touch, see our Galway post here for more info: https://esbarchives.ie/2017/09/18/connecting-galway-to-the-national-grid/
