Rising rooftop solar output pushes demand on Western Australia’s grid to all-time low

That’s below the previous record of 1135MW set in January this year, but the Australian Energy Market Operator expects that further lows will be set this spring and in following years.The record fell on the same weekend that new winter lows for minimum demand were set in Victoria and South Australia, according to AEMO, both also the result of increased generation from rooftop solar, and low overall demand.The lows for minimum demand levels are falling rapidly. “This was the fourth consecutive quarter in which a minimum quarterly demand record was set, of which two were all-time minimum demand records, highlighting the continuing impact of distributed PV on demand patterns and quantities in the WEM,” AEMO said in its latest Quarterly Energy Dynamics statement.This new record takes the number of consecutive quarters with a new minimum demand record to five, including three which are all time records.[Giles Parkinson]More: Rooftop solar: W.A. sets new record low for grid demand, two other states set winter lowslast_img read more
