Solaria maps €2.5bn plan, battery joint venture, fresh PPAs

• Solaria outlined a €2.5bn plan for 2026–2028, launching a battery JV and signing new PPAs to turn solar into evening power.

Solaria is putting real money behind a simple idea: solar is great at noon, but the grid really needs help after dark. The Spanish developer laid out a €2.5 billion plan for 2026–2028, with more than half going to new PV projects and the rest to the equipment and contracts that make those megawatts truly useful — a new battery joint venture and a slate of fresh PPAs.

The battery JV is the tell. By co-locating two-to-four-hour storage at existing and future solar sites, Solaria can catch mid-day surpluses and pour them into the evening ramp, when prices spike and flexibility is scarce. Co-location keeps costs in check (one grid connection, shared substation) and makes dispatch simpler. A fleet-level software layer will juggle energy shifting, frequency response and voltage support without running the batteries flat when they’re needed most.

On the contracting side, new PPAs will matter as much as hardware. Corporate buyers increasingly want predictable prices and cleaner power by the hour, not just certificates. Hybrids help Solaria offer that shape — less curtailment at noon, more delivery when offices and factories are humming.

The engineering remains thoroughly bankable: high-efficiency modules on trackers, sensible DC/AC sizing, and plant controllers that play nicely with Spain’s evolving grid code. Permitting now bakes in biodiversity plans, glare and noise limits, and credible end-of-life pathways for both modules and batteries.

In short, this isn’t just a bigger pipeline; it’s a smarter one. Spend on PV builds the base. Spend on storage and PPAs turns that base into reliable evening megawatts the system will pay for.
