The expansion of the Ngawha Geothermal Power Station creates a more affordable, reliable and secure electricity supply for the Far North. Once complete, generation capacity will more than double to 57 Megawatts.

Installation of power station, geothermal pipeline and electricity transmission system equipment is in progress with upwards of 150 people now active on site at any one time. The works continue to progress and the power station is expected to be fully operational by the end of 2020.

Good news for Northlanders

Ultimately, expansion of the Ngawha Geothermal Power Station will provide a renewable and lower cost source of electricity generation with clear benefits for local consumers:

  • Security of supply and reliability will be improved
  • The region will become less reliant on generation from the south and associated transmission through Auckland

Safe, reliable and renewable

Geothermal energy is a safe and reliable energy source. It’s not dependent on rainfall like hydro-power or other fluctuations in supply, and is considered renewable and sustainable energy source.

The generation model sees the geothermal fluids extracted injected back into the underground reservoir, minimising environmental impacts and maintaining the reservoir fluid mass.

Good for the whole country

The expansion of the power station contributes towards the Government’s target of greater than 90% renewable electricity generation by the early 2030’s and supports its climate change objectives. It will also improve national electricity security of supply, by contributing 0.6% of total national electricity production from a steady and renewable source.
