Wind, hydro help boost renewable electricity generation

Published: 13 March 2020

A boost in hydro and wind generation in the final three months of 2019 helped lift renewable electricity generation above 85 per cent for the quarter according to the New Zealand Energy Quarterly released today by the Ministry of Business, Innovation and Employment.

The latest New Zealand Energy Quarterly covers the period October-December 2019 and provides quarterly data and analysis on energy supply, demand, prices and associated greenhouse gas emissions.

“Renewable sources accounted for 85.4 per cent of electricity generation for the December 2019 quarter,  up 1 percentage point compared to the same quarter a year earlier,” says Daniel Griffiths, MBIE Manager of Markets, Evidence and Insights.

“An increase in hydro generation (up 3.1 per cent) and wind generation (up 31.3 per cent) saw renewable generation rise by 3.4 per cent on the 2018 quarter, hitting its second highest share for a December quarter in the last 20 years, surpassed only by 2016.

“A decline in the amount of electricity generated from coal also helped lift the renewable share. Coal used for electricity declined by almost 30 per cent with coal contributing 4.3 per cent of total generation for the latest quarter, down from 6.3 per cent of the total a year ago.

“Nationally, the demand for electricity rose by 0.2 per cent on the previous December quarter with higher agricultural and commercial sector demand driving the increase despite a decline in industrial demand,” says Griffiths.
