Olkiluoto 3
Finland · FI · commissioned 2023 Europe's most powerful single reactor and the first new reactor to come online in Finland in over four decades. Its 1,600 MW feed the Finnish grid, part of the interconnected Nordic system.
1,600 MW capacity12 g CO₂/kWh
Gravelines
France · FR · commissioned 1980 Western Europe's largest nuclear power station by installed capacity — six 900 MW PWR reactors on the North Sea coast of northern France. A critical anchor of the French grid.
5,460 MW capacity12 g CO₂/kWh
Bełchatów Power Station
Poland · PL · commissioned 1982 The single largest lignite-fired power station in Europe — and historically the largest single CO₂ point source on the continent. Over 5 GW of capacity anchors the grid in central Poland.
5,053 MW capacity1000 g CO₂/kWh
Hornsea 2
United Kingdom · GB · commissioned 2022 The world's largest offshore wind farm at launch — 165 turbines, 8 MW each, 89 km off the Yorkshire coast. Feeds directly into the GB grid via subsea cables.
1,320 MW capacity11 g CO₂/kWh
Plant of the day Cattenom
France · FR · commissioned 1987 Four 1,300 MW PWR reactors on the Moselle, about 12 km from the Luxembourg border — one of France's largest nuclear sites by capacity.
5,200 MW capacity12 g CO₂/kWh
Sima Hydro
Norway · NO_5 · commissioned 1980 One of Norway's largest hydropower plants, its turbines built into the mountains at the head of the Eidfjord and fed by high reservoirs on the edge of the Hardangervidda. Delivers some of the cleanest electricity on the continent.
1,120 MW capacity24 g CO₂/kWh
Paluel
France · FR · commissioned 1984 Four 1,330 MW PWR reactors on the Normandy coast — Europe's second-largest nuclear power station by capacity, feeding the French grid and exports across the Channel.
5,320 MW capacity12 g CO₂/kWh
Vemork Hydro
Norway · NO_2 · commissioned 1971 On the site of Norsk Hydro's 1911 plant, world-famous for the WWII heavy-water sabotage that set back the Nazi atomic programme. The original powerhouse is now a museum; an underground station commissioned in 1971 still generates here today.
204 MW capacity24 g CO₂/kWh
Dukovany
Czech Republic · CZ · commissioned 1985 Czech Republic's older nuclear plant — four VVER-440 reactors. New units are planned here, making it one of the few active nuclear expansion projects in continental Europe.
2,040 MW capacity12 g CO₂/kWh
Beznau 1
Switzerland · CH · commissioned 1969 The world's oldest operating commercial nuclear reactor, commissioned in December 1969. Still generating clean electricity for the Swiss grid more than five decades later.
380 MW capacity12 g CO₂/kWh
Hornsea 1
United Kingdom · GB · commissioned 2019 The first gigawatt-scale offshore wind farm in history. Operates alongside Hornsea 2 and the under-construction Hornsea 3, making the Hornsea cluster the world's largest wind energy zone.
1,218 MW capacity11 g CO₂/kWh
Olkiluoto 2
Finland · FI · commissioned 1982 One of two older BWR reactors at the Olkiluoto site, operating alongside the new EPR. Together the three Olkiluoto reactors supply close to a third of Finland's electricity.
890 MW capacity12 g CO₂/kWh
