Renewable power eases grid stress in the US and Australia

Rooftop solar installations across New England significantly reduced electricity demand during an early‑July heat wave, supplying up to 25 % of the region’s load at peak times and saving customers an estimated $130 million in wholesale costs. The distributed generation shifted the daily peak away from the hottest afternoon hours, easing strain on ISO‑New England’s grid.

In Australia, the Australian Energy Market Commission (AEMC) is consulting on new market rules for battery storage and other flexible loads to manage Minimum System Load (MSL) events. Proposals include automatic price floors during severe MSL periods and a paid ancillary‑service market for storage, aiming to improve investment confidence for battery projects such as the 250 MW Torrens Island system. The reforms are part of a broader effort to address projected reliability gaps and to meet the 35 GW of short‑ and medium‑duration storage identified as required by 2050.
