renewables PM market analysis — 2026-08-23

The renewables story this session is less about adding generation and more about making existing capacity dependable. Arevon and the Solar Energy Industries Association frame utility-scale solar as a mature, centralised source of clean power, while ESS points to storage as the mechanism for shifting that output to when demand actually needs it. The emphasis has moved from build-out to integration.

That shift is running into physical limits. Energy-Storage.News highlights growing interest in grid-forming battery technology as a way to add system strength on grids that are leaning more heavily on inverter-based resources. But the Los Angeles Times reports that batteries meant to stabilise the grid are sitting idle because transmission and connection equipment is not ready to accept them. Oilprice.com adds a similar caveat: batteries make variable wind and solar more usable, but they do not eliminate intermittency by themselves.

The read-through is that hardware is arriving faster than the grid infrastructure and market design needed to use it. Progress on utility-scale solar and storage deployment continues, but the practical value of that build-out depends on connection timelines and whether markets pay properly for flexibility and reliability services, not on generation capacity alone.
