Initial earthworks began October 2017.
The Ngāwhā hot springs are not impacted by this project.
Construction of the power station was completed by August 2020. After a thorough commissioning and testing programme to confirm that it operates as intended and all safety systems are proven, it started generating electricity in December 2020.
Ngawha Generation Ltd is expected to take over full operational responsibility for the new power station by March 2021.

- While the well drilling operation (now completed) was 24/7, further night works are unlikely until commissioning starts in August 2020.
As most of the work is happening on Top Energy’s property you should not be adversely impacted by the construction. There will be a number of truck and trailer units required to transport metal, materials, and power station equipment to the site. This means that there will be increased heavy traffic along the selected routes of SH 1, SH 12 and Ngawha Springs Road during the project construction and close-down stages.
