Renewables hit more than 80 pct of grid demand for first time – despite heavy throttling of wind and solar

The 80% renewables milestone is offset by heavy curtailment of wind and solar output, revealing grid stability constraints that force rejection of available low-cost generation. This illustrates the real operational cost of high renewable penetration: firming and grid management demand are rising faster than storage can absorb, exposing the gap between nameplate renewable capacity and usable supply on the NEM.
