Power without the carbon? OERC Seminar

OERC Seminar by Grant Telfar, Modelling Manager, Meridian Energy Limited

About the talk:

The Government has stated its desire for a 100 per cent renewable power system by 2030. New generation projects will move the system to 90 per cent renewable by 2024. Hydro power inflow deficits of 5TWh have historically been managed by maintaining sufficient thermal capacity, fuel storage, and deliveries.

The Government are proposing the Onslow-Manorburn pump storage scheme as a key plank towards solving ‘dry years’ without the need for thermal backup.

The Climate Change Commission see electricity as an enabler to unlock decarbonisation in the economy and have recommended relying on gas-fired generation as Aotearoa transitions towards a low carbon future. A Tiwai Point smelter closure by the end of 2024 could see 5TWh of excess Southland-Otago generation flowing northward. In response, large-scale demand stimulation projects are being pursued.

Significant new demand in the region could address this energy imbalance, help green the global economy, and potentially create an alternative power system dry-year solution.

About the speaker:

Grant is the Modelling and Portfolio Manager at Meridian Energy and has been employed by Meridian in specialist economic, strategic, and power system modelling and analysis roles focused on both the NZ and Australian electricity systems since 1999.

Prior to 1999, he worked as an energy sector analyst in New Zealand, Singapore, Malaysia, the UK, and in Australia.

Grant’s area of specialty includes the economic assessment of future power system supply and demand needs within an increasingly renewable power system and a decarbonising NZ and global economy.

Grant’s expertise in hydro-thermal power system analysis and modelling has been used from operational decision making through to long-term investment.
