Horns Rev is an offshore wind farm in Danish waters in the North Sea.
The wind farm was built in three phases, the first coming online in 2002, the second in 2009 and the third in 2019.
Horns Rev 1, the first phase, was the first large-scale offshore wind farm in the world, with a capacity of 160 MW.[http://www.modernpowersystems.com/story.asp?storyCode=2017033 Horns Revolution] {{webarchive|url=https://web.archive.org/web/20110714110540/http://www.modernpowersystems.com/story.asp?storyCode=2017033 |date=14 July 2011 }}, Modern Power Systems 5 October 2002.

Horns Rev 1, built by Danish energy company Elsam (later DONG, now Ørsted) was the first large-scale offshore wind farm in the world. Its capacity of 160 MW was four times that of the previous largest, the Middelgrunden at 40 MW.Morgan, Colin.

It was the first offshore wind farm in the North Sea, the first to use the monopile foundation type and the first to have its transformer on an adjacent platform rather than onshore.[https://www.4coffshore.com/windfarms/horns-rev-1-denmark-dk03.html Horns Rev 1 Offshore Wind Farm] C4 Offshore Technologies used for the first time at Horns Rev 1 have since become industry standard.
The farm has 80 Vestas V80 wind turbines, each generating 2.0 MW. They were installed by the Danish offshore wind farm services provider A2SEA in 2002, the last turbine coming into operation on 11 December 2002. A guaranteed price of 0.453 DKK/kWh was agreed for the first 42,000 hours of generation.{{cite web|url= http://www.ens.dk/sites/ens.dk/files/energistyrelsen/Nyheder/2014/pso-fremskrivning_2014_19052014.pdf |title=Fremskrivning af PSO-udgifter|page=4|publisher=Danish Energy Agency|date=19 May 2014|access-date=17 January 2015|language=da|trans-title=Projection of PSO Expenses}}
In 2005, 60% of the wind farm was sold to Vattenfall, also the operator of the park, for DKK2bn.{{cite web|title=Horns Reef Wind Farm, Denmark|url= http://www.power-technology.com/projects/hornsreefwind/ |publisher=power-technology.com|accessdate=1 December 2011}}{{Unreliable source?|reason=domain on WP:BLACKLIST|date=June 2016}}
The turbines are laid out in an oblique 8 by 10 grid over an area of 5 km × 3.8 km, with 560 m between turbines in both directions. A radar measures details of the wind patterns, improving local short-term forecasting.{{cite web |last=Pinson |first=Pierre |url=http://pierrepinson.com/?page_id=354 |archive-url=https://web.archive.org/web/20191031081025/http://pierrepinson.com/?page_id=354 |archive-date=31 October 2019 |title=Radar@Sea}}[http://www.posspow.vindenergi.dtu.dk/ PossPOW: Possible Power of Offshore Wind power plants] Technical University of Denmark

Sea conditions render the area inaccessible to boats for large parts of the year.
The farm has an availability of 96–97%. Two turbines are burnt out, and uneconomic to replace with less than 10 years left. Grout between monopile and tower was damaged by vibrations, requiring a costly fix.{{cite web |last1=Episode 5 |title=Incredible Engineering Blunders: Fixed |url=https://www.discoveryuk.com/series/incredible-engineering-blunders-fixed/ |website=Discovery UK |archiveurl= https://web.archive.org/web/20191218210825/https://www.discoveryuk.com/series/incredible-engineering-blunders-fixed/ |archivedate=18 December 2019 |url-status=live}}

The Horns Rev 2 consists of 91 Siemens Wind Power SWT 2.3-93 wind turbines with a total generating capacity of 209 MW. The foundations are monopiles like on Horns Rev 1.
It has the first offshore wind farm accommodation platform in the world, named Poseidon.

Horns Rev 3
In April 2012, most of the Danish Folketing (parliament) agreed to send out tenders in 2013 for a 400 MW wind farm at Horns Rev called Horns Rev 3, and a 600 MW at Kriegers Flak in the Baltic Sea, both likely receiving 90 øre/kWh for the first 50,000 hours.
