The Numbers Are In: CATL and NextEra's Latest Earnings Confirm Storage Has Arrived as a Profit Center
GLOBAL — July 31, 2026 — Two earnings reports released this week tell the same story from opposite sides of the world: energy storage is no longer the side business — it's becoming the main event.
CATL: Storage is Now 19.23% of Revenue
CATL, the world's largest battery manufacturer, disclosed in its H1 2026 financial report that its energy storage division generated 19.23% of total company revenue in the first half of the year — nearly one-fifth of all income at a company historically defined by electric vehicle batteries.
This is not a rounding error. For a company of CATL's scale, 19.23% represents tens of billions of dollars in storage-specific revenue. And the trajectory is clear: storage's share of CATL's business has grown every quarter for the past two years, driven by:
- Utility-scale BESS deployments hitting new records globally
- Sodium-ion commercialization adding a new product category
- AI data center demand creating an entirely new storage vertical
The implication: the company that built its empire on EV batteries is now structurally dependent on storage for growth. When CATL allocates R&D, factory capacity, and supply chain priority, storage is no longer competing with EVs for scraps — it's a peer.
NextEra: "Battery Storage is an Important Growth Driver"
Meanwhile, in the United States, NextEra Energy — already America's largest renewable energy developer — reported Q2 2026 earnings up 9.5% year-over-year. In its earnings call, CEO John Ketchum explicitly named battery storage as "an important growth driver" for the company.
This comes as NextEra advances its merger with Dominion Energy, a deal that would create the largest regulated utility in US history. A combined NextEra-Dominion would have a generation portfolio, a transmission network, and — critically — a storage deployment pipeline that no competitor can match.
When the likely soon-to-be largest US utility calls storage a "growth driver," it signals that BESS has moved from pilot-project territory to core infrastructure spending.
The Bigger Picture: Four Earnings Season Takeaways
| Company | What They Said | What It Means |
|---|---|---|
| CATL | Storage = 19.23% of H1 revenue | Storage is now structurally material to the world's largest battery maker |
| NextEra | Storage named as growth driver in Q2 call | The largest US renewable developer is betting its growth on BESS |
| ESS Tech (last week) | Stock +20.7% after SIB launch | Wall Street is pricing sodium-ion as a real market |
| Ark Energy (this week) | AU$1.3B locked for 2.2 GWh solar+storage | Project finance is flowing to large-scale storage at record levels |
The pattern is unmistakable: in Q2 2026 earnings season, storage is not a footnote in anyone's financial statements. It's a headline.
What This Means for the Supply Chain
When the world's largest battery maker (CATL) and America's largest renewable developer (NextEra) both signal that storage is central to their growth plans, the supply chain implications are immediate:
- Cell production capacity will be allocated to storage first, not last — reversing the historical priority of EVs over stationary storage
- Pricing for premium cells (314Ah, 324Ah, and specialized SIB formats) will become more competitive as scale drives costs down
- Lead times for standard components will shrink for suppliers with established manufacturing relationships — and lengthen for everyone else
For project developers and distributors, the message is: your cell supplier's relationship with tier-1 manufacturers is now a competitive advantage. Those who can secure allocation from CATL-scale producers will deliver projects on time. Those who can't will wait.
