'''Keadby Power Stations''' are a pair of natural gas-fired power stations near [[Scunthorpe]] in [[North Lincolnshire]], built on the site of an older coal power station. The site lies near the B1392 and the [[River Trent]], and the Scunthorpe-[[Grimsby]] [[South TransPennine|railway]]. Also nearby is the [[Stainforth and Keadby Canal]], which is part of the [[Sheffield and South Yorkshire Navigation]]. The current stations are operated by [[SSE Thermal]].

SSE also owns a 68 MWe capacity wind farm, [[Keadby Wind Farm]], nearby. This was England's largest onshore wind farm, and started operating in July 2014.<ref>{{cite news|url=http://renews.biz/70608/sse-hungry-for-more-at-keadby/|title=SSE hungry for more at Keadby|newspaper=reNEWS|date=17 July 2014 |access-date=14 November 2015|archive-url=https://web.archive.org/web/20160116072812/http://renews.biz/70608/sse-hungry-for-more-at-keadby/|archive-date=16 January 2016|url-status=dead}}</ref><ref>{{cite web|url=http://sse.com/whatwedo/ourprojectsandassets/renewables/keadbywindfarm/|title=SSE Renewables, the renewable energy development division of SSE, acquired the Keadby wind farm project in North Lincolnshire in May 2011|publisher=SSE |access-date=14 November 2015|archive-url=https://web.archive.org/web/20140409063053/http://sse.com/whatwedo/ourprojectsandassets/renewables/keadbywindfarm/|archive-date=9 April 2014}}</ref>

==Keadby Gas Power Station==
Keadby Gas Power Station was commissioned on 22 January 1996, and was opened by [[Scottish Hydro Electric]] and [[NORWEB]] when the site was in [[South Humberside]]. Scottish Hydro bought the 50% share of Keadby Generation Ltd, then owned by United Utilities, in March 1997 for £253&nbsp;million. It is now owned by [[Scottish and Southern Energy]].

In March 2013 the power station was 'deep mothballed' in response to adverse market conditions; it reopened in December 2015 after winning a stand-by contract to provide 734 MWe of capacity.<ref>{{cite web|title=SSE Announces Reopening of Keadby Gas Fired Power Station|url=http://sse.com/newsandviews/allarticles/2015/10/sse-announces-reopening-of-keadby-gas-fired-power-station/|website=SSE|access-date=8 May 2017|date=20 October 2015|archive-url=https://web.archive.org/web/20151023010149/http://sse.com/newsandviews/allarticles/2015/10/sse-announces-reopening-of-keadby-gas-fired-power-station/|archive-date=23 October 2015}}</ref><ref>{{cite news|url=http://www.scottishenergynews.com/sse-cranks-up-mothballed-keadby-gas-fired-power-station-as-winter-back-up-for-uk-renewable-energy/|title=SSE cranks up mothballed Keadby gas-fired power station as winter back-up for UK renewable energy|newspaper=Scottish Energy News|date=21 October 2015|access-date=14 November 2015}}</ref><ref>{{cite web |url=http://sse.com/whatwedo/ourprojectsandassets/thermal/keadbypowerstation/|title=Keadby Power Station|publisher=SSE|access-date=14 November 2015|archive-url=https://web.archive.org/web/20160211103015/http://sse.com/whatwedo/ourprojectsandassets/thermal/keadbypowerstation/|archive-date=11 February 2016}}</ref>

It is a [[Combined cycle|CCGT]] type power station running on natural gas. There are two [[General Electric]] Frame 9FA [[gas turbine]]s each rated at 250&nbsp;MWe. The total thermal input is 1329&nbsp;MW. Each gas turbine is connected to a [[heat recovery steam generator]] which connect to one [[steam turbine]] which has an output of 260&nbsp;MWe. Steam is condensed using water from the River Trent. There is a 25&nbsp;MWe 11&nbsp;kV gas turbine available for [[black start]]s when there is no power to start producing electricity. The station connects to the [[National Grid (UK)|National Grid]] at 400&nbsp;kV, being used for [[Base load power plant|baseload]].

==Keadby 2==

In 1999, Scottish Hydro applied to add another 710&nbsp;MWe of capacity at Keadby, and a variation to this consent was granted in November 2016. The project, called 'Keadby 2', was announced in May 2018.<ref>{{cite web |url=http://sse.com/whatwedo/ourprojectsandassets/thermal/keadby2/ |title=On 25 May 2018, SSE announced its decision to proceed with the construction of a new 840MW Combined Cycle Gas Turbine (CCGT) power station at Keadby 2. |publisher=SSE|access-date=11 August 2018|archive-url=https://web.archive.org/web/20180816065940/http://sse.com/whatwedo/ourprojectsandassets/thermal/keadby2/ |archive-date=16 August 2018}}</ref> It uses a single [[Siemens Energy]] SGT5-9000HL turbine.

Construction on the plant, now rated at 893&nbsp;MWe, began in August 2018.<ref>{{Cite web |title=Keadby2 Power Station |url=https://www.siemens-energy.com/uk/en/offerings-uk/keadby2-power-station.html |access-date=2023-02-26 |website=siemens-energy.com Global Website |language=en}}</ref> The station was planned to come online in October 2022, but this date was missed, with the plant coming online in February 2023.<ref>{{Cite news |last=Laister |first=David |date=2023-01-20 |title=SSE gives update on Keadby Two Power Station delay |language=en |work=Business Live |url=https://www.business-live.co.uk/manufacturing/sse-gives-update-keadby-two-26033136 |access-date=2023-02-26}}</ref> {{asof|2024}}, Keadby 2 at 849 MW is the biggest single-turbine combined cycle powerplant in the world, and the most efficient at 64%.<ref>{{cite web |last1=Largue |first1=Pamela |title=Siemens Energy sets world records at UK's Keadby 2 Power Station |url=https://www.powerengineeringint.com/gas-oil-fired/siemens-energy-sets-world-records-at-uks-keadby-2-power-station/ |website=Power Engineering International |date=20 June 2024}}</ref><ref>{{cite web |title=Most efficient combined cycle power plant |url=https://www.guinnessworldrecords.com/world-records/431420-most-efficient-combined-cycle-power-plant |publisher=[[Guinness World Records]] |date=21 May 2024}}</ref>

==Keadby Three==
In December 2022, development consent was obtained for a third plant on the Keadby site. Keadby Three is planned to be a 910&nbsp;MWe plant with [[carbon capture and storage]], with opening planned as soon as 2027.<ref>{{Cite news |last=Laister |first=David |date=2022-12-08 |title=Humber carbon capture power station given go-ahead |language=en |work=Business Live |url=https://www.business-live.co.uk/economic-development/humber-carbon-capture-power-station-25702076 |access-date=2023-02-26}}</ref>

==Keadby coal-fired station==
The first power station on the site was authorised in 1947 and work on the foundations began in July 1948. It was designed to have a total capacity of 360 MW.<ref name=":0">{{Cite book|editor-last=Garrett|editor-first=Frederick C. |title=Garcke's Manual of Electricity Supply|publisher=Electrical Press|year=1959|location=London|pages=A-66–67, A-124}}</ref>

The plant comprised six Stirling radiant type, [[Pulverized coal-fired boiler|pulverised fuel]], twin furnace boilers. Each boiler had an evaporation capacity of 550,000&nbsp;lb/hr (69.3&nbsp;kg/s) of steam, the total evaporative capacity of the completed station was 3,300,000&nbsp;lb/hr (415.8&nbsp;kg/s). Steam conditions were 925 psi and 915&nbsp;°F (63.8  bar and 490.6&nbsp;°C).<ref name=":0" />

There were six [[C. A. Parsons and Company|Parsons]] 60 MW hydrogen cooled [[Alternator|turbo-alternators]], generating at 11 kV. The first set was commissioned in April 1952, followed by the other sets in November 1952, June 1953, June 1954, December 1954 and December 1955.<ref name=":0" /> In 1952 the boiler associated with the first set was the largest yet commissioned in the UK.<ref>{{Cite book|last=Electricity Council|title=Electricity Supply in the United Kingdom: a Chronology|publisher=Electricity Council|year=1987|isbn=085188105X|location=London|pages=66}}</ref>

It was officially opened in April 1956, and cost £16m.<ref>''Times'' Saturday August 4 1956, page 4</ref>
