THE LINGO• Energy: electricity or combustion fuels (petrol or gas)• Generation: assets that generate electricity • Hydroelectric systems• Geothermal power plants• Thermal power stations (gas, coal or diesel)• Wind• Solar• Demand: the level of consumption by industry or residential consumers• Behind the Meter (BtM): Generation that happens on the energy user’s side of the meter.• Front of the Meter (FtM): Generation on a utility scale, that occurs on the grid side of the meter.Hydroelectric – Clyde Dam Power StationGeothermal – Te Mihi Power StationThermal – Huntly Power StationWind – Tararua Wind Farm
THE PROBLEM
GENERATION PROFILE HAS SEEN ~25% INCREASE IN DEMAND IN 20 YEARS AND GROWTH OF NEW GENERATION SOURCES Source: International Energy Agency https://www.iea.org/countries/new-zealandPercentage breakdown as of 2022:Coal – 3%Gas – 10% Biofuels – 2%Hydro – 60% Geothermal – 18% Wind – 7%Oil, solar PV and other sources account for less than 1% each10 TWh increase

NZ GOVERNMENT COMMITMENTS – THE END OF THE RAINBOW These targets aim to limit climate change, and ensurea renewable and secure supply of energy into the futureNet zero emissions by 2050(excluding biogenic methane – methane from agriculture and waste)50% of total energy consumption will come from renewable sources by 203550% reduction in GHG emissions from 2005 levels by 2030100% renewable electricity by 2030(an aspirational target)Currently ~40% of total energy consumption comes from renewables
