renewables PM market analysis — 2026-08-24

Renewables are on track to overtake coal-fired generation globally this year, with solar doing most of the work, according to the IEA’s latest electricity outlook. The report frames this as a structural shift in the generation mix rather than a one-off swing, though it pairs the milestone with a caveat: grids need stronger transmission and more flexibility to absorb the added output efficiently.

That caveat showed up in practice during recent European heatwaves and droughts. System operators reported that high solar output eased pressure on the grid during daylight hours, but they were equally clear that storage is what covers the gap once the sun goes down. The read-through is that solar’s daytime contribution is no longer in question, while the evening supply picture still depends on batteries and demand management catching up.

Policy is starting to reflect that split. Australia’s newly announced financing mechanism is aimed specifically at smaller, grid-ready projects that combine generation with batteries, a design meant to shorten connection timelines rather than simply add capacity. Taken together, the IEA data, the European grid experience and the Australian financing model point in the same direction: the growth story in renewables is increasingly about hybrid, storage-paired projects rather than generation capacity alone.
