The work continued for more than two decades. ESB’s own archival research shows that the final communities under the Rural Electrification Scheme were connected in 1977. ESB crews travelled from county to county, building lines, installing poles and connecting homes. Progress was slow at first. Many families were unsure of the cost and the value of electricity, and some communities hesitated before signing up. Over time the benefits became clear. Electric light, running water, milking machines and household appliances transformed daily life and reduced the physical burden of farm and domestic work.

The scheme is remembered as one of the most important social projects of the twentieth century. It changed how people lived, worked and organised their homes. It supported education, improved health and made rural life more secure. It also helped narrow the gap between town and country and gave families access to the same modern services as the rest of the state.

Rural electrification remains a landmark in Ireland’s development. It shows how infrastructure can reshape society and how national investment can reach into the everyday lives of people and families. It is a reminder that energy policy is never only technical. It is also human.

Even so, it was 1996 before locations like the Aran Islands were finally connected to the national grid.
