Tennessee-made lithium iron phosphate cells will supply 10 GWh of utility-scale battery storage to US integrator Prevalon over three years. The ownership restructuring behind the deal is a working example of how the OBBBA material-assistance rules are reshaping who can sell US BESS cells.
Texas grid operator's large-load interconnection queue nearly quadrupled in a year to 226 GW, with 77% from data centers. Q1 2026 alone added 198 GW of new applications. Texas PUC faces a December 2026 deadline to finalize transparency rules separating real projects from speculation.
A US District Court ruling vacates the Treasury guidance that eliminated the 5% cost safe harbor, restoring the longstanding pathway developers used to lock in 45Y/48E credits ahead of the July 4 begin-construction cutoff. An appeal is expected, and the deadline still looms.
American Battery Technology Company won an Informal Dispute Resolution appeal and had its DOE Manufacturing Energy Supply Chain grant reinstated in full. The award funds the first phase of a Nevada lithium hydroxide refinery sized at 5,000 tonnes per year.
Panasonic confirmed on June 12 that it is exploring converting its 32 GWh De Soto, Kansas cell factory from EV batteries to data-center BESS production, with first conversion cells targeted for late 2028 or early 2029. The pivot reads as the cleanest US example yet of EV-built capacity rebalancing toward AI and grid storage demand.
FERC approved PJM's Expedited Interconnection Track on June 9, opening a narrow lane for up to ten 250 MW-plus projects per year that can come online within three years. The carveout sits next to the still-pending large-load rule and tilts the queue toward state-backed incumbents.
Three deals in the last twelve days (AESC-Prevalon, Panasonic De Soto, T1 Energy-KORE) plus the Pentagon's June 8 Section 1260H expansion mark a shift in how the US battery-supply thesis should be read. The story is no longer 'how many GWh of cell capacity is sited in the US,' it is 'how many of those GWh are eligible for IRA-credit projects after the One Big Beautiful Bill Act's material-assistance test.' Run the math on credit-eligible incremental cell supply available to US grid-storage developers in H2 2026 and the curve is materially tighter than the announced 100-plus GWh of nameplate domestic capacity implies. Eligible supply is the binding constraint on storage deal flow into 2027, not nameplate.
The third PJM capacity auction under a $175 floor and $325 cap (with annual adjustments) closes July 7, 2026. The prior two auctions cleared at the cap, and the consensus expectation is that this one does as well. The data worth reading is not the headline number but the megawatt count of new entry, the share of storage cleared with current ELCC accreditation, the demand-resource volume, and which LDAs separate at higher locational caps. Those four lines determine whether the policy lever pulled at FERC on April 28 is shaping supply or only redistributing rent.
The first of last week's three policy clocks landed: FERC approved PJM's Expedited Interconnection Track on June 9, opening a state-gated fast lane for up to ten 250 MW projects per year that can come online inside three years. The bigger demand-side clock (FERC RM26-4-000 on large-load interconnection) is now scheduled for the June 18 open meeting. Across the supply stack the same theme repeated in different chemistries and balance sheets: CATL signed the first commercial-scale sodium-ion offtake (60 GWh to HyperStrong), Panasonic disclosed plans to convert part of its 32 GWh De Soto cell factory from EV to data-center BESS, and the Pentagon added JA Solar, Trina, EVE, and CALB to the Section 1260H list with the direct DoD contracting ban starting end of June. Stoel Rives' OBBBA read confirmed that storage kept both safe-harbor paths and the 2027 placed-in-service backstop while solar above 1.5 MW lost both. ACP's Q1 2026 quarterly put solar and storage at 93 percent of new utility-scale grid additions. Thesis intact across all five active verticals; the supply chain is being reshaped in policy and capital structure faster than in price.
Because generalist coverage buries the supply-chain and policy texture. A permitting decision on a transmission project, a DOE loan commitment to a lithium refinery, an NRC licensing milestone for an SMR, a FERC rulemaking on interconnection reform: these move capital in ways that earnings coverage misses. Clean Power Press is built for the people who track those signals.
Long-horizon. The thesis is a multi-decade buildout. The daily briefs work for tactical positioning, but the analytical frame is structural: supply-chain, policy, project-pipeline. If you're trading micro-moves on spot prices, this isn't your tool.
Energy storage and lithium, solar, nuclear and SMRs, grid and transmission, and critical minerals. Climate policy is the connective tissue. The verticals are separate editorial frames but they share a common insight: the bottleneck on every one of them is permitting, supply-chain concentration, and policy implementation, not the underlying technology.
Climate change is established science. We don't give false balance to fossil-fuel-industry framing on the science. Our editorial stance is climate-forward: the clean energy transition is necessary, urgent, and one of the most consequential investment stories of the next several decades. That's not advocacy. We report facts, cover setbacks as well as progress, and don't oversell the pace of transition.
Track marginal, watch policy, ignore most price noise. The marginal capex dollar, the marginal project entering permitting, the marginal regulatory decision: these are where the structural story moves. Average inventory levels, spot price tapes, and quarterly headlines follow later and with lower signal value.
