Location

The wind farm will be located about 15 kilometres south-east of Gore, within an area of 2,568 hectares (25.68 km2).[3]

Construction

The project received resource consent in June 2008.[4] In September 2018 Tilt said that the development was waiting for favourable market conditions.[5] In June 2021 Tilt announced the project was being acquired by Mercury Energy.[6] In June 2022 Mercury began talks with the local community over the wind farm.[7]

Installation of an initial ten turbines totalling 43MW of generation is expected to start in October 2022.[8][9][10] Earthworks began in the first week of October 2022.[11] A sod-turning ceremony was held in November 2022.[12] As of February 2023, Mercury say they expect all turbines to be operational by October 2023.[13] The first turbines arrived in April 2023, and will be transported to the site during May and June.[14]
