Station register

Every row on this page is a row of the sheet List of Electricity Generators in Historical electricity data: 1920 to 2025, published by the Department for Energy Security and Net Zero (DESNZ). The list was compiled for DESNZ's March 2024 article on where generation has been located. Nothing is fetched live: the page is built from the spreadsheet itself, and rebuilt when a new edition appears.

Rows

1,291, commissioned 1888–2022, of which 1,205 have a grid reference; three are duplicates, leaving 1,288 sites

Added from DUKES

105 sites, 9.7 GW between them, from the 2026 edition of DUKES table 5.11 (OGL v3): 57 sites opened 2023–2026 (7.0 GW), which a list that ends in 2022 cannot include, and 48 of 5 MW or more that opened earlier and that it omits (2.7 GW); marked DUKES, with DUKES's own grid reference, and counted in nothing that is about the list

The fuel is DESNZ's, as corrected. Where DUKES lists the same site, hover the fuel to see how DUKES words it, and the download has it as a column: 997 of the 1,393 sites have it. Edmonton is Bioenergy here, as DESNZ counts waste, and DUKES says Waste (municipal solid waste) · Bioenergy.

What this page changed. Spellings of the same fuel or region are merged (solar and Solar, North west and North West), 269 wrong positions are replaced, 63 sites with no usable point are placed and 54 put approximately at their town, 26 rows are corrected and three duplicate rows are left out — each listed below. Nothing else is altered.

What this list can’t tell you

DESNZ warns about it. Its own note on the sheet says: “It is an experimental database and therefore may contain errors.”

It covers major generators only, and its newest commissioning year is 2022. 22 rows have no region. The 105 sites from DUKES are the 57 it names after that and 48 it omits of 5 MW or more; DUKES is itself a table of major stations, and its 2026 figures are the newest and the least revised. They carry no closure year, so every one counts as operating.

Each row has one capacity for its whole life. A station that was extended, uprated or partly closed carries a single figure throughout, so a league for an early year ranks sites by a number some reached only later.

Rows are not always stations. Most are — Hinkley Point A and B are two stations, as they were built — but some are the units of one scheme: Rheidol's seven hydro generators rank as seven small sites.

Rows corrected

A row is corrected only where it contradicts itself or the rest of the list and an independent source says which way. The capacity is kept as listed unless the listed figure belongs to another station. Each is listed below, and the CSV says what changed and where the evidence is.

Every row's fuel was then checked against Wikidata and the planning database: 721 of the 1,288 sites have a record of the same name within 5 km, and 49 of those disagreed. Ten were errors and are corrected here. The rest were checked by hand: 24 are another station on the same site, or the same one after a change of fuel; 5 are gas turbines that burn oil; 10 are a different plant nearby sharing the name; and none is left unresolved. The other 567 sites have no such record and could not be checked this way, so more errors may remain.

Every row operating since 2004 was also compared with every edition of DUKES 5.11 (2004 to 2026), the table the list was compiled from: 895 match an entry by name and region. 14 of the corrections here rest on it. After them, 3 rows still differ on fuel — Grange, which DUKES itself lists twice, and two later sites to which DUKES gives an older station's name. Capacities differ for 18 and opening years for 44; DUKES revises both between editions, so those are kept as listed.

1. Row 9, Great Yarmouth coal — fuel gas → coal; capacity 252 → 11.25 MW. The row is named for Great Yarmouth's coal station and carries its years, 1894–1961, but was labelled gas and given 252 MW — the capacity of the oil-fired South Denes station (row 107). By 1959 the coal station had one 7.5 MW and one 3.75 MW turbo-alternator. Sources: Wikipedia: Great Yarmouth Power Station.
2. Row 101, Great Yarmouth — fuel coal → gas. The Great Yarmouth station that opened in 2001 is a 420 MW combined-cycle gas station. Labelled coal, it was also treated as closed after the last year of coal. Sources: Wikidata Q5600309 (Great Yarmouth Power Station); Wikipedia: Great Yarmouth Power Station.
3. Row 127, Ferrybridge C — region East Midlands → Yorkshire and The Humber. Ferrybridge is at Knottingley, West Yorkshire. Sources: Wikidata Q117196738 (Ferrybridge C Power Station); Wikipedia: Ferrybridge power stations.
4. Row 146, Low Spinney — fuel solar → wind. Low Spinney is a wind farm: four turbines, 8 MW, in Leicestershire, operational in September 2011 — the same place, size and year as this row. DESNZ's planning database has no solar site of that name. Sources: DESNZ Renewable Energy Planning Database, Q2 2026: Low Spinney Wind Farm (Ref ID 3682).
5. Row 166, Staythrope — left out — a duplicate of row 165. "Staythrope" is Staythorpe C misspelt. It has row 165's grid reference to the metre (476750, 353668), and its 1,772 MW is DUKES's capacity for Staythorpe C in the 2015 and 2017–2022 editions. DUKES has only ever listed one gas station at Staythorpe, commissioned in 2010. With no dates the row never counted in a year, but it ranked as a station of its own in the all-time league. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Staythorpe C / Staythorpe, CCGT, 1,724–1,828 MW, 2010 (editions 2011–2026).
6. Row 189, Grange — fuel solar → wind. The Grange Wind Farm in Lincolnshire — seven turbines, 14 MW, operational in March 2013 — matches this row in size and year, 1.3 km from its grid reference. DUKES listed "Grange" as wind, 14 MW, 2013; later editions list the wind farm twice, at the same grid reference, once as wind and once as solar, and this row follows the second. Sources: DESNZ Renewable Energy Planning Database, Q2 2026: The Grange Wind Farm (Ref ID 3671); DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Grange, wind, 14 MW, 2013 (edition 2013); Grange Wind Farm (GB), wind, and Grange, solar, both at 545055, 318754 (2022–2026).
7. Row 195, Ratcliffe-on-Soar — fuel coal → oil. This 34 MW row is not the coal station, which is row 130. It is Ratcliffe's gas-oil gas turbine, which DUKES lists separately as diesel/gas oil, single cycle, 34 MW, 1967. Labelled coal, it was also treated as closed after the last year of coal. DUKES lists it to its 2025 edition and not in 2026. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Ratcliffe (OCGT), diesel/gas oil, 34 MW, 1967 (editions 2019–2025); Ratcliffe (Steam), coal, 2,021 MW, 1967.
8. Row 204, Lots Road — closed 1960 → 2002. Lots Road ran until 21 October 2002, when the turbines were switched off after 97 years. It burned coal, then heavy fuel oil from the 1960s, then gas from 1974–77; the list has one fuel per row, and coal is kept because the 50 MW is the capacity at opening. Sources: Wikipedia: Lots Road Power Station; Wikidata Q1871101 (Lots Road Power Station, ended 2002).
9. Row 241, Greenwich — fuel coal → gas; closed 1990 → no closure year. The 120 MW is the capacity of the gas turbines that replaced the coal-fired steam plant (117.6 MW), not of the 1906 station, and they still stand: Greenwich remains the emergency supply of London Underground. Steam generation from coal ceased on 8 February 1972; the turbines first burned light fuel oil, the first were switched on for natural gas on 11 February 1976, and gas has been the normal fuel since, with oil kept as standby. The list has one fuel per row, so the coal and oil years are not shown. Sources: TfL Corporate Archives, Research Guide 30: Lots Road and Greenwich Power Stations; Wikipedia: Greenwich Power Station.
10. Row 244, Londonwaste Ltd — left out — a duplicate of row 246. Rows 244 and 246 are one plant, the Edmonton energy-from-waste plant. LondonWaste Ltd was its operator until it was renamed LondonEnergy Ltd in 2016, and DUKES lists a single entry for it in every edition, as Edmonton to 2020, LondonEnergy Energy Centre in 2021 and Londonwaste Ltd from 2022 (1970 throughout; 50 MW in 2022, 55 MW in 2026). The planning database has the one record, Edmonton EcoPark EfW, 55 MW. This row has the operator's name, DUKES's 2022 capacity and a grid reference copied from Drakelow's (381396, 270649); it sits 0.7 km from row 246, which has the site's name and today's capacity and is kept. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Edmonton / LondonEnergy Energy Centre / Londonwaste Ltd, municipal solid waste, 1970: one entry in each edition 2013–2026, 55 MW in 2026; LondonEnergy, Our History: LondonWaste Ltd renamed LondonEnergy Ltd in 2016; Wikipedia: Edmonton EcoPark; DESNZ Renewable Energy Planning Database, Q2 2026: Edmonton EcoPark EfW, 55 MW (Ref ID 4924).
11. Row 287, Blyth — closed none → 2019. This is the two-turbine pilot farm commissioned in December 2000, which was decommissioned in 2019 as its consent required; the five-turbine Offshore Demonstrator that replaced it is the row named Blyth wind. The capacity is kept as listed (the two Vestas V66 turbines were 2 MW each). Sources: Wikipedia: Blyth Offshore Wind Farm; Wikidata Q4930860 (Blyth Offshore Wind Farm, ended 2019).
12. Row 319, Wilton 10 — fuel gas → bioenergy. Wilton 10 is Sembcorp's biomass station on Teesside, commissioned in 2007. DUKES has listed it as biomass in every edition since 2010, at exactly this row's 33.276 MW from 2019 to 2022. This row's fuel and Wilton International's (row 321) look swapped. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Wilton 10, biomass, 38 → 33.276 → 35 MW, 2007 (editions 2010–2026).
13. Row 321, Wilton International — fuel bioenergy → gas. Wilton International is Sembcorp's 120 MW gas-fired plant: DUKES lists it as natural gas at exactly this row's capacity, as "Wilton GT" from 2018 to 2021 and under this name since 2022. This row's fuel and Wilton 10's (row 319) look swapped. The opening year is kept as listed; DUKES gives the site's, 1952. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Wilton GT, natural gas, 120 MW (editions 2018–2021); Wilton International, natural gas, 120 MW (2022–2026).
14. Row 324, Hornsea 01 — region North East → Yorkshire and The Humber. Hornsea 01 is an offshore wind farm more than 100 km off the East Yorkshire coast. This row's own grid reference and DUKES's agree on 53.68°N 1.42°E, off Yorkshire rather than the North East, so as filed the point failed the region check and the largest wind farm in the list was left off the map. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Hornsea 01, offshore wind, 1,218 MW, 2019, at 53.68°N 1.42°E (editions 2019–2026); Wikidata Q84277667 (Hornsea One Offshore Wind Farm).
15. Row 427, Littlewood — region North West → East Midlands. Littlewood is Anesco's 5 MW solar farm at postcode NG19 8JA, by Mansfield in Nottinghamshire. DUKES's 2026 edition lists it in the East Midlands at SK 53307 65197; its 2022–2025 editions, like this row, filed it under North West with the grid reference of Littlewood Farm, Buckinghamshire (row 894), a different solar farm. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Littlewood, Anesco, solar, 5 MW, East Midlands, NG19 8JA, SK 53307 65197 (edition 2026).
16. Row 484, EP Kilroot — fuel gas → oil; opened 1981 → 2009 (about). This is Kilroot's four standby gas turbines, 142 MW, which burn distillate oil: DUKES has listed them as gas oil in every edition that shows them. 1981 is the coal and oil station's opening year (row 439), not theirs. DUKES counts Kilroot at 520 MW every year to 2008, then 600 MW in 2009 and 662 MW in 2010 — the 520 MW station plus these 142 MW — so the turbines came into service around 2009, when two 42 MW units are reported installed. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Kilroot OCGT, gas oil, 142 MW (editions 2012–2018); EP Kilroot, diesel/gas oil (2022–2026); Kilroot, 520 → 600 → 662 MW (2008–2010); EP UK Investments: Kilroot; POWER magazine, 1 August 2016: Kilroot Power Station; Wikipedia: Kilroot power station.
17. Row 486, CoolkeeraghESB GT8 — fuel gas → oil. CoolkeeraghESB GT8 is a 53 MW open-cycle gas turbine at Coolkeeragh that burns diesel or gas oil: DUKES has listed it so, under this name, in every edition since 2021. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: CoolkeeraghESB GT8, diesel/gas oil, OCGT, 53 MW (editions 2021–2026).
18. Row 487, EP Ballylumford — fuel gas → oil. EP Ballylumford is Ballylumford's open-cycle gas turbines, commissioned in 1974, which burn diesel or gas oil: DUKES has listed them so, under this name and at 116–120 MW, in every edition since 2021. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: EP Ballylumford, diesel/gas oil, OCGT, 116–120 MW, 1974 (editions 2021–2026).
19. Row 505, Dalchonize Power Station-A,C — fuel coal → hydro; closed 2000 → no closure year. Dalchonzie is a 4 MW hydro station, commissioned in 1958. DUKES listed it as hydro every year from 2004 to 2015, and under this row's own name from 2022 to 2026, so it did not close in 2000 either. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Dalchonzie, hydro, 4 MW, 1958 (editions 2004–2015); Dalchonize Power Station-A,C, hydro, 4 MW, 1958 (2022–2026).
20. Row 508, Lussa Power Station - A — fuel coal → hydro; closed 2000 → no closure year. Lussa is a 2.4 MW hydro station, commissioned in 1952. DUKES listed it as hydro every year from 2004 to 2015, and under this row's own name from 2022 to 2026, so it did not close in 2000 either. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Lussa, hydro, 2–2.4 MW, 1952 (editions 2004–2015); Lussa Power Station - A, hydro, 2.4 MW, 1952 (2022–2026).
21. Row 691, Dalswinton — fuel gas → wind. Dalswinton in Dumfries and Galloway is a wind farm of fifteen turbines, 30 MW, operational in March 2008 — at this row's grid reference, with its capacity and year. Sources: DESNZ Renewable Energy Planning Database, Q2 2026: Dalswinton (Ref ID 4520).
22. Row 873, Cowes A — fuel coal → oil. Cowes' 140 MW station, opened in 1982, is two 70 MW gas turbines that burn light fuel oil. Cowes had a coal station, but it was 24 MW and closed in 1976. Labelled coal, this row was also treated as closed after the last year of coal. Sources: Wikidata Q5179664 (Cowes Power Station); Wikipedia: Cowes Power Station.
23. Row 894, Littlewood A — fuel bioenergy → solar. Littlewood Farm in Buckinghamshire is a 14 MW solar farm, operational in March 2015 — this row's size and year, 1.2 km from its grid reference. No bioenergy site of the name is in the planning database. Sources: DESNZ Renewable Energy Planning Database, Q2 2026: Littlewood Farm (Ref ID 2182).
24. Row 918, Grain Oil — fuel gas → oil; years 2011–(open) → 1979–2012; capacity 1,365 → 1,300 MW. Grain's oil-fired station ran from 1979 to 2012 and has been demolished; DUKES listed it at 1,300 MW, commissioned 1979, until 2012. As published, the row — gas, 2011, 1,365 MW, still open — is word for word DUKES's entry for the gas station beside it (row 917) in its 2023 and 2024 editions, under the oil station's name, so it counted as a second gas station still running. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Grain, oil, 1,300 MW, 1979 (editions 2007–2012); Grain CCGT, 1,365 MW, 2011 (2023–2024); Wikidata Q117191844 (Grain Power Station, oil); Wikipedia: Grain Power Station.
25. Row 937, Thanet — fuel coal → wind. A 300 MW site at Thanet opened in 2010 is Thanet Wind Farm: 100 turbines of 3 MW, opened in September 2010. The row's own grid reference agrees — it is at sea, 0.2 km from the wind farm's position in Wikidata. Labelled coal, it was also treated as closed after the last year of coal. Sources: Wikidata Q1576615 (Thanet Wind Farm); Wikipedia: Thanet Wind Farm.
26. Row 952, Poole — fuel oil → coal; opened 1955 → 1950. Poole Power Station at Hamworthy was coal-fired, supplied by sea, from its first set in December 1950 until 1993. 1955 is the year an oil burner was fitted, not a change of fuel. Its listed 335 MW is its capacity in the early 1960s, and is kept. Sources: Wikidata Q18343594 (Poole Power Station); Wikipedia: Poole Power Station.
27. Row 1023, Lynch Knoll — fuel coal → wind. Lynch Knoll is a single 0.5 MW wind turbine, commissioned in 1996: DUKES lists it as onshore wind, at this capacity and year, in every edition since 2022. Labelled coal, it was also treated as closed after the last year of coal. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Lynch Knoll, onshore wind, 0.5 MW, 1996 (editions 2022–2026).
28. Row 1226, Ferrybridge C — left out — a duplicate of row 127. Ferrybridge C was one coal-fired station of four 500 MW sets, 1966–2016. No gas-fired station was ever built there — the planned Ferrybridge D was dropped in 2020 — and its only gas turbines were small start-up units. This row repeats row 127 under gas, so the station was counted twice. Sources: Wikidata Q117196738 (Ferrybridge C Power Station); Wikipedia: Ferrybridge power stations.
29. Row 1234, Thornhill power station — fuel coal → gas. Thornhill is a gas-fired station: DUKES listed it as a 50 MW CCGT commissioned in 1998 — this row's capacity and year — from 2009 to 2020, and as natural gas since. Labelled coal, it was also treated as closed after the last year of coal. Sources: DESNZ, Digest of UK Energy Statistics (DUKES) table 5.11: Thornhill, CCGT, 50 MW, 1998 (editions 2009–2020); natural gas, 40 MW (2023–2026).

Capacities noted

A capacity is kept as listed. Where a better-sourced figure differs, it is noted beside it: hover the capacity, or see the CSV's Notes column.

1. Edmonton EcoPark, 55 MW as listed — The North London Waste Authority's 2015 need assessment for the replacement plant says the existing plant generates around 40 MWe gross. The list, DUKES (2026) and the planning database give 55 MW, as does Wikipedia. Source: North London Waste Authority, North London Heat and Power Project: Need Assessment (AD05.04, NLWA/Eunomia/Arup, October 2015), on the current use of the EcoPark.
2. Calder Hall, 220 MW as listed — The list's 220 MW, which DESNZ's June 2023 Energy Trends article on capacity since 1920 also gives, matches four reactors of 55 MWe each, the installed capacity given in a 1996 paper on the plant. The IAEA's reactor data, as published by the World Nuclear Association, gives each reactor 60 MWe gross and 50 MWe net, so 240 MWe gross and about 200 MWe net; Wikipedia also gives 240 MWe. Source: P R Gallie, Forty years of operation of Calder Hall, ATW 41(11), November 1996 (abstract): four reactors, each with 55 MWe installed capacity; World Nuclear Association, Reactor Database: Calder Hall 1 (net 50 MWe, gross 60 MWe); Wikipedia: Calder Hall nuclear power station.
3. Battersea B, 503 MW as listed — The 503 MW listed here is the whole station in 1955, Stations A and B together: Station A is 243 MW (row 228) and Station B 260 MW, two 100 MW sets and one 72 MW set, as Wikipedia gives them. The Survey of London puts the finished station at over 500,000 kW. Read with row 228, the list counts Station A twice, 746 MW in all. Source: Survey of London, Battersea (vols 49-50), chapter 9, Battersea Power Station: first sets 67,200 kW and 105,000 kW in Station A, 100,000 kW sets in Station B, total output over 500,000 kW; Wikipedia: Battersea Power Station.

“Operating in” means between the commissioning and closure years — the same rule as the map on the Since 1920 page, so the two always agree. A site with no closure year is treated as still open, and some closure years are planned rather than actual. The exception is coal: the series records no coal generation after 2024, so the 3 coal sites listed with no closure year show by 2024 and are not counted after it.

Map positions are checked, not surveyed. As published, 184 grid references put their site outside its own region and 132 more are copies of another region's point. 192 are corrected from Wikidata (149) or the planning database (43), 54 are confirmed where DESNZ put them. DESNZ's own station table, DUKES 5.11, gives a grid reference for most sites operating since 2004. It places 18 sites the list gives no usable point, and moves 62 whose point was more than 3 km from DUKES's — often hundreds, in Scotland, where a wrong point can still fall inside the region. 28 of these 80 are confirmed by Wikidata or the planning database; the other 52 rely on DUKES alone, and say so. Where an independent source backs the list's point instead, it stays. Of the sites that have no grid reference in the list, 45 are placed by the same matching rules, from Wikidata or the planning database. And every offshore wind farm is checked against the coastline: Galloper and Aberdeen had a point on land — Galloper's in Cambridgeshire — and are moved to a point at sea from the sources. DUKES's own earlier editions, and the planning database, sometimes give an offshore wind farm the place its cable comes ashore. 13 sites had another site's point — the same grid reference, in the same region, so no region check could see it (Roosecote A, in Barrow, had Kearsley's, near Bolton) — and are moved to their own from Wikidata or the planning database. Last, 54 sites that no source places — mostly early municipal stations, closed long before DUKES begins — are put at the town they are named after, from Wikidata: approximate, drawn as hollow rings on the map, and labelled so. 17 still cannot be placed. The Map position column says which; hover it for the record used, and the CSV carries latitude and longitude.
