An energy researcher thinks the government's decision to scrap a pumped hydro scheme at Lake Onslow is presumptuous.
Energy Minister Simeon Brown told me the choice to pull back government investment will open more opportunities for the market to invest renewable energy.
But Otago University's Jen Purdie says it's a bad idea to stop the work.
She says the government may as well finish costing and assessing the project - in case we need pumped hydro in future.
Purdie spoke to Corin Dann.
