Nationwide power worries – Transpower issues warning as winter big chill kicks in, threat now under control
Transpower this morning issued a nationwide warning notice – revealing there was a risk of insufficient power generation and reserve to meet the country’s demand – as Kiwis woke to a bitterly cold day.
The state-owned enterprise issued the warning today as the first big winter chill has hit this week, with Kiwis most likely pumping their heaters.
Transpower CEO Alison Andrew said this morning’s grid emergency was due to losing generation from three sources including a Contact Energy power station, Genesis’ power station in Huntly and a wind drop from 90 to 30 megawatts.
“This morning we called a grid emergency just before 8am, which is during the morning peak, to make sure we could stabilise grid security.”
Speaking to Newstalk ZB’s Kerre Woodham, Andrew said the emergency was all over by 9.30am and most consumers wouldn’t have noticed.
Lines companies were asked to reduce their controllable load which impacts things like hot water cylinders, said Andrew.
“As a system operator we have to manage the power system in real time and when these situations happen we need a good response from our industry participants to make sure we keep the lights on for New Zealanders.”
Asked how the entity would handle a similar situation in a future where everyone was driving electric vehicles, Andrew said they are working hard to find new ways to be able to respond.
She said there is a lot of interest to build renewable energy sources in New Zealand, with over 100 inquiries, but that this work comes with peculiar challenges and solutions for dry years and winter peaks need to be found.
“At Transpower we are working hard to make sure we have the capacity to connect people up to the grid for their new demand or generation as quickly as we can.”
The notice, which was issued at 7.58am, said “This is a New Zealand-wide emergency”.
“The System Operator advises there is a risk of insufficient generation and
reserve offers to meet demand and provide N-1 security for a contingent event.”
