If you want to know where the U.S. grid is going, look at what's actually getting built. In the first quarter of 2026, solar and battery storage made up the large majority of every new megawatt added to the system — not in a forecast, but in interconnection-and-commissioning reality. Everything else combined is now a rounding error against the two cheapest, fastest resources to deploy.
Storage in particular just had its strongest start to a year on record. The U.S. installed roughly 9.7 GWh of battery storage in Q1 2026, up about 32% year over year, according to the American Clean Power Association and Wood Mackenzie's quarterly market report. That follows a 2025 in which the country added more than 28 GW / 57 GWh of storage, with utility-scale projects supplying the bulk of it.
Solar's share of the mix climbed just as fast. Utility-scale solar and wind together reached a record 17% of U.S. electricity generation in 2025, the U.S. Energy Information Administration reported — and solar is now the single largest source of new capacity year after year.
Why it's happening now
Two forces are pulling in the same direction. The first is demand: after two flat decades, U.S. electricity consumption is rising again, driven by data centers, AI compute, and electrification. The second is speed. A solar-plus-storage project can be permitted, financed, and energized in a fraction of the time it takes to build firm thermal or nuclear capacity — and at a lower levelized cost. When a grid needs gigawatts in a hurry, solar and storage are simply what shows up.
The question is no longer whether to build solar and storage. It's how fast you can get them interconnected.
The friction is real — but it's about logistics, not economics
This isn't a frictionless boom. Tariffs pushed the price of some four-hour U.S. battery systems up by as much as 69% during the first half of 2025, even as global lithium-ion pack prices fell to a record low near $108/kWh by year-end. And the binding constraint on new projects is increasingly the interconnection queue: backlogs and permitting timelines now weigh on a meaningful share of the early-stage pipeline.
None of that changes the underlying economics. It changes who wins — the developers who lock in supply chains early, site inside constrained capacity zones where the grid actually needs the power, and treat interconnection as a discipline rather than an afterthought.
What it means for Solyx
This is the market we were built for. Solyx develops utility-scale solar paired with long-duration storage in the exact places the grid is short — and we treat siting, supply chain, and interconnection as the hard parts, because they are. The macro tailwind is obvious; the edge is in execution.
