Hydro slips in energy mix

A new energy report released by the Ministry of Business, Innovation and Employment (MBIE) has shown a decline in the share of electricity generated from renewable sources for the third quarter of 2019.

The New Zealand Energy Quarterly states that reduced inflows into North Island hydro schemes contributed to the decline.

Manager of Markets, Evidence and Insights at MBIE, Daniel Griffiths said renewable sources made up around 81 per cent of electricity generation, down from 85 per cent for the same quarter a year ago.

“Nationally, hydro generation compared to the same quarter a year earlier, fell by seven per cent, but it was down by almost 19 per cent in the North Island,” Mr Griffiths said.

“This comes at a time when overall electricity generation is at its highest since 2011.”

He said other sources of generation picked up the slack with wind generation hitting a record high for any September quarter, while coal-fired generation was more than double that recorded a year earlier and gas-fired generation rose by 13 per cent.

“Electricity consumption was up by two per cent on September 2018 as demand rose across all sectors,” Mr Griffiths said.

“The national average price for fuel fell compared to a year earlier, with petrol falling four per cent and diesel seven per cent,” he said.
