New Zealand’s durable lines company Transpower told a meeting in Invercargill that Hydro dams stations and wind farms in the lower South Island are important for the long-term future of electricity.
Transpower chief executive Alison Andrew presented the company’s white paper, Te Mauri Hikop-Energy Futures, in Invercargill this week. This provided research on what New Zealand's energy requirements could look like up to 2050.
She said increasing usage of electricity in the transport and industrial sectors will help reduce the amount of carbon released into the atmosphere. Transpower considered decarbonising as a priority for the coalition Government in its post-2020 commitment to reduce greenhouse gas emissions under the Paris Agreement.
The Southland Times quoted Andrews as saying solar and geothermal energy, hydro lakes and wind farms throughout the country would play a big part in generating the vast amounts of electricity needed by 2050.
“We're going to use all the renewable resources we can. Southland has renewables that are critical for New Zealand.”
PowerNet director Don Nicolson asked if New Zealand was not involved with Paris Agreement would Transpower have done the white paper. She replied that part of the company's future proofing was to prepare for a carbon neutral energy future by 2050.
According to the Southland Times report, Chamber of Commerce representative Mark O'Connor was reassured wind farms in Southland were important contributor's to Transpower's future.
Researchers for the white paper assume 100% of coal and 40% of gas, as industrial fuels, will be replaced by electricity by 2050. New Zealand's electricity demand is estimated to more than double from 40 terawatt hours per annum currently to 90 terawatt hours by 2050.
Transpower's researchers claim electric vehicles will control 40% of the market share by 2030 and 85% by 2050.
“EVs will be cheaper to run, cheaper to buy, cheaper to maintain and will have a longer lifespan than internal combustion engine vehicles,” according to the white paper. An increase in heavy transport vehicles being electrified is also expected.
Researchers believe conventional liquid fuels will decline based on current technology and its future economics.
