The Lake Onslow project is designed to serve as a giant battery to help protect against hydro electricity shortages and create more stability in the market. The Ministry of Business, Innovation and Employment said Energy Minister Megan Woods would provide a brief project overview to her Cabinet colleagues this month. Part of the feasibility studies and investigation work would look at environmental impact, as raising the level of Lake Onslow would lose wetland that lead into it.
