Given we usually generate at least 55 percent of our electricity from hydroelectric power, the low lake levels have raised alarm in the energy sector over security of supply. Lake levels lowThe scheme is huge, putting Think Big projects of the past in the shade. Lake Onslow would produce 5,000 GWH a year, doubling New Zealand's entire hydro capacity. It would go a long way to solving the dry year problem and fill New Zealand's generation needs for decades. However, the energy sector has been generally sceptical about this as well.Feb 16, 2021 · This is particularly a problem in a renewable electricity system when the hydro lakes are dry, as hydro is one of the few renewable electricity sources that can be stored during the day (as water ...
