London Array is the now world’s largest offshore wind farm, generating enough electricity to power nearly half a million homes. The wind farm has just placed its last wind turbine in order to switch online as the world’s largest. Located in the Thames Estuary, the farm consists of 175 turbines that will power the area from Essex to Margate. Phase one of the London Array, owned by Dong Energy, Masdar and EON and consisting of 141 turbines (630 MW), is now fully functional.
London proper is already known for being home to the world’s largest solar bridge, at Blackfriars, and now Kent joins the renewable energy elite with London Array, which is only around 50 miles from the capital. The London Array has been under construction since March of 2011 and its Siemens 3.6MW turbine kicked into power six months ago. The first phase has been coming along quickly and since last Thursday has been pumping wind power into the grid. The developers of the London Array are also using the project as a case study in order to lower costs for large scale wind farms in the future. DONG Energy has the ultimate goal of creating offshore wind farm projects that yield usable wind power at around $152 per megawatt hour by 2020. The next phase will be to get the remaining 34 turbines online, as well as to bury remaining cables. Phase one itself is anticipated to provide power for half a million homes a year, which will save 925,000 tonnes of carbon dioxide emissions per year.
