  1. Estimated annual running costs for electricity and natural gas are calculated using energy prices indicative of competitive 2022/23 pay-on-time offers advertised by the major energy retailers for residential customers in the Ausgrid network area and the Jemena mains gas network area.
  2. Greenhouse gas emissions are estimated using the National Greenhouse Factor of 0.79 kg/kWh for the electricity generated and distributed in NSW and 0.06463 kg/MJ for natural gas distributed to metropolitan users in NSW. These factors are published by the Department of Climate Change, Energy, the Environment and Water in the Australian National Greenhouse Accounts Factors, February 2023.
