Sorne Hill wind farm
The Sorne Hill Wind Farm is a wind farm located in Buncrana, Inishowen County Donegal, Ireland. The development was completed in 2006 and is operated by Bord Gáis Energy. Turbines. Phase 1 of the farm has 16 gearless wind turbines, type Enercon E-70 2 [MW] with a 64-metre hub height and 71 metre rotor diameter giving a total capacity of 32 megawatts. Phase 2 of the farm, which is an additional 6.9 MW from three Enercon E-70 2.3 MW turbines, were installed in the Autumn of 2007. This made Sorne Hill Wind Farm, at 38  MW, the third largest wind farm in Ireland as of August 2008. In 2007, there was a feasibility study published which examined the economics of installing a flow battery at Sorne Hill Wind Farm. While the economic case for the system was compelling, the technology was not ready for deployment at that point in time. A new company, REDT, retained the rights to the ESS site at Sorne Hill, and plans to install a utility scale system at some point in the future, subject to funding.
