Since the inception of the state, the first Shannon hydroelectric scheme was constructed in 1929 with seven years of independence. Built by Siemens-Schuckert with Irish engineers doing much of the design and using mostly Irish labour, it has an 86MW capacity with an annual generation 332GWh.{{cite web |title=Ardnacrusha |publisher=ESB Group |year=2023 |url=https://esbarchives.ie/portfolio/river-shannon/ |access-date=30 December 2023 }} This was followed up by the much larger Turlough Hill and only pumped-storage built into the mountain with a capacity of 292 megawatts completed in 1974 after 6 years of construction.{{cite web |title=Turlough Hill |publisher=ESB Group |year=2023 |url=https://esbarchives.ie/portfolio/turlough-hill/ |access-date=30 December 2023 }} A few other smaller hydroelectric stations exist around the country, such as Pollaphuca{{cite web |title=Pollaphuca |publisher=ESB Group |year=2023 |url=https://esbarchives.ie/portfolio/river-liffey/ |access-date=30 December 2023 }} and Inniscarra Dam.{{cite web |title=Inniscarra |publisher=ESB Group |year=2023 |url=https://esbarchives.ie/portfolio/river-lee/ |access-date=30 December 2023 }} Catherine Halpin, Ardnacrusha's plant manager suggests that the four main hydro plants are availing of about 70% of the country's water resources.{{cite web |last=Doyle |first=Carmel |title=Ireland’s Ardnacrusha hydro-electric power station – a clean-tech exemplar? |work=Innovation |publisher=Silicon Republic |date=14 August 2012 |url=https://www.siliconrepublic.com/innovation/irelands-ardnacrusha-hydro-electric-power-station-a-clean-tech-exemplar |access-date=30 December 2023 }}

A tidal energy system is in operation since 2008 in Strangford Lough producing 1.2 megawatts using an underwater windmill" whose rotors at driven by the tidal currents. It has a capacity to produce enough electricity for about 1,000 homes.{{cite web |title=Tidal energy system on full power |work=Northern Ireland News |publisher=BBC News |date=18 December 2008 |url=http://news.bbc.co.uk/1/hi/northern_ireland/7790494.stm |access-date=30 December 2023 }}
