how much additional gas generation will be required to be added to the South
West Interconnected System to achieve the government's self-imposed coal
closure timeframe?(2) Who or whom will provide the required

Hon Jackie Jarvis replied:Thank you,
President. I prefer not to use my full title; it makes me feel tired!I thank the
honourable member for some notice of the question. The following response has
been provided by the Minister for Energy and Decarbonisation.(1) The amount of gas generation capacity required
in future years is dependent on several factors, including actual demand
growth, new generation and storage entering the market, the type of new capacity
entering, and the actual uptake of rooftop solar and household battery storage.(2) The Australian Energy Market Operator seeks
capacity—generation, storage and demand-side participation—each
year for the capacity year, which is 1 October to 30 September, two years
subsequent, based on the capacity needed to meet electricity demand in the
South West Interconnected System. Market entry to provide generation and
storage in this annual process is a matter for current and prospective energy
market participants.(3)–(4) Least-cost generation modelling
has informed development of the upcoming SWIS transmission plan, and is
underpinned by confidential information provided by project proponents.
