Transpower has announced this morning it will allow generators to take more water from hydro lakes to help with the electricity crunch.
Generators will be allowed to breach consents to access contingent lake storage. Transpower says if conditions worsen, it may call on the public to conserve electricity use, to help free up supply.
Kathryn speaks to Transpower's Executive general manager of operations, Chantelle Bramley, Mercury's chief executive Vince Hawkesworth and energy economist Stephen Poletti.
