renewables PM market analysis — 2026-09-02

Solar and storage procurement continues to expand, but the pace of realised output is increasingly determined by grid capacity rather than generation capacity alone. S&P Global Market Intelligence reports that utilities and corporations kept favouring solar power purchase agreements through the first half of 2026, with storage increasingly paired in to address reliability needs and rising electricity demand. Solar Power World data point to record quarterly energy-storage installations in the US, consistent with grid operators and buyers seeking flexibility alongside renewable generation.

India’s experience, as reported by the Associated Press, illustrates the constraint side of this picture: transmission and interconnection gaps, together with insufficient storage, are curtailing clean generation even when power demand is strong. That reinforces a theme visible in broader project activity tracked by Energy Global, where solar, wind, hybrid generation, standalone batteries and battery-optimisation agreements all point to growing emphasis on firming and operational flexibility rather than raw capacity additions.

Taken together, the evidence favours continued contracting momentum for solar-plus-storage in markets with adequate transmission, while flagging execution risk where grid buildout lags generation growth. Storage economics are also shifting toward optimisation, capacity and ancillary-service revenue streams rather than energy arbitrage alone.
