Electricity demand in WA set to fall for first time, AEMO forecasts, as solar power takes over

The body that runs the national wholesale electricity market is forecasting demand for electricity from households and businesses in WA will fall for the first time as the extraordinary uptake of solar panels reshapes the power system. Key points: "Operational consumption" of power is set to fall almost 4 per cent by 2027-28 At the same time, the share of homes with solar panels is set to top 50 per cent The change highlights the financial problems facing power retailer Synergy In its latest report on the south-west wholesale electricity market, the Australian Energy Market Operator said it was no longer expecting the use of power drawn from the grid to increase as the state's population grew. Instead, AEMO said it was forecasting demand — or "operational consumption" — to fall almost 4 per cent between 2019–20 and 2027–28, bucking long-held assumptions that link power use to an economy's size. At the heart of the operator's latest forecast is the "extraordinary" take-up of rooftop solar power, with more than one in four homes in the south-west grid now having a solar system. Mr Davis said the trend of falling demand for grid-drawn power and the increasing self-reliance of customers with solar panels also served to highlight many of the problems facing state-owned power retailer Synergy.
