As part of the transformation of the network to support the continued uptake of renewables, the WA State Government has introduced Emergency Solar Management (also known as Distributed Photo Voltaic Management or DPVM) as a last resort measure to manage the risks of minimum demand and its impact on secure electricity supply in the South West Interconnected System.

From 14 February 2022, all new and upgraded residential inverters installed with a capacity of 5kVA or less need to be capable of being remotely switched off (and back on) during an extreme minimum demand event.

This new measure will not interrupt power supply, as the grid will continue to supply power to customers, and it is expected to be utilised only several times a year for a few hours.

Western Power, Synergy, Energy Policy WA, and Australian Energy Market Operator (AEMO) have been working closely with industry to implement emergency solar management capability.
