Enbridge and Meta sign $1.2B Wyoming solar + 8-hour storage for AI data centers

Enbridge will build a 365 MW solar farm paired with a 200 MW / 1,600 MWh battery system near Cheyenne to anchor Meta data center load. The 8-hour storage duration is the detail worth reading: it pushes well past the 2-to-4-hour shape that has dominated US grid-scale BESS, and signals that hyperscaler-anchored PPAs are now buying firming, not just energy.

Federal Permitting Improvement Steering Council (permitting.gov), March 30 2026; USGS Appalachian lithium assessment, April 28 2026 us-supplypermitting

Kings Mountain clears federal permitting as USGS sizes Appalachian lithium at 2.3 million tonnes

The Department of Energy completed federal permitting for Albemarle's Kings Mountain lithium project in North Carolina on March 30, 2026, and a USGS assessment released April 28 estimated 2.3 million metric tonnes of undiscovered, economically recoverable lithium across the southern Appalachians and the Northeast. Together, the federal clearance and the resource estimate reframe the Carolinas as a near-term US lithium supply node, not a long-shot one. State and local approvals still gate first production, and the assessment is undiscovered resource, not reserves, so the marginal-capex dollar is what to track next.

Spearmint closes $450 million on 600 MWh Texas BESS with August COD, ITC-transfer tax equity in the stack

Spearmint Energy reached financial close on Red Egret, a 300 MW / 600 MWh ERCOT battery project in Texas City, with $225 million construction debt, $126 million of investment tax credit transfer commitments, and $96 million of preferred equity from Nuveen. Commercial operations are targeted for August 31, 2026. The capital stack is a clean read on how IRA-era transferability is now routinely funding standalone storage in ERCOT, and the three-month finance-to-COD window shows how compressed the build cycle has become for permitted Texas BESS.

PJM Inside Lines, April 29 2026 news release interconnectiondata-centers

PJM's first reformed-cycle intake closes at 220 GW, with nuclear seated alongside storage and gas

PJM announced on April 29 that 811 generation projects totaling 220 GW applied to the first cycle of its reformed interconnection process, with natural gas leading by capacity (105.8 GW, 157 projects), storage leading by project count (66.5 GW across 349 projects), and nuclear posting a 17.9 GW entry that is unusually large for a single queue cycle. The mix is the cleanest read yet on where developer conviction sits under post-Order-2023 rules: dispatchable capacity to chase data-center load, storage to firm renewables, and a real nuclear cohort lining up behind hyperscaler procurement.

FERC Docket EL26-39-000, May 21 2026 Commission meeting summary solarinterconnection

FERC affirms PJM at-risk readiness deposits, denies solar developer withdrawal complaint

FERC on May 21 denied a complaint by Gaston Green Acres Solar and Bethel NC Hwy 11 Solar against PJM Interconnection, leaving in place the at-risk Readiness Deposit framework that holds Transition Cycle No. 1 developers to their cost allocations even when network upgrade costs jump materially between Phase III and the final retool study. The ruling is a procedural denial but a substantive signal: late-stage queue economics are now harder to walk away from, which raises the bar on developer cost discipline and reduces cost-shift risk for the projects that remain in the cycle.

Second-life BESS finds a FEOC workaround as Moment Energy lands a UL-certified BMS

Moment Energy announced on May 19 that its battery management system for second-life energy storage has been awarded UL functional safety certification, with Energy-Storage.News reporting it as a world first for a repurposed-cell BMS. The company is staking the claim that cells already in the United States, harvested from retired EV packs, escape the prohibited-foreign-entity sourcing rules that took effect this year under IRS Notice 2026-15. Second-life is not a primary supply lane for grid storage, but the FEOC compliance crunch keeps narrowing the lithium options that pencil for IRA tax credits, and this is the first formal regulatory bridge under the new rules.

Large power transformer lead times have stretched past 30 months, and the orderbook is now the binding constraint on grid buildout

Grid-scale step-up transformers in the 138 kV and 230 kV class are now quoting 24 to 30 month lead times at the major OEMs, with some 345 kV and 500 kV units pushing past 36 months. The bottleneck is not modules, cells, or capital. It is grain-oriented electrical steel, skilled assembly labor, and an OEM footprint that was sized for a different decade of demand. The constraint applies equally to solar, storage, nuclear, and data center substation builds.

The week broke wide across verticals. NextEra agreed to acquire Dominion in an all-stock $67 billion deal that, if cleared, makes the combined entity the second-largest US nuclear operator and the dominant generation counterparty inside PJM. Two days later PJM disclosed that Cycle 1 of its reformed interconnection process drew 811 projects at 220 GW, with nuclear posting a 17.9 GW queue entry that does not have a recent precedent. Hydrostor entered a 500 MW, 8,000 MWh A-CAES project into Ontario's long lead-time RFP, the third non-lithium long-duration capital event inside eight days. FERC affirmed PJM's at-risk readiness deposit framework, holding the cost discipline that keeps the cleaned-up queue clean. Spearmint closed $450 million on a 600 MWh ERCOT BESS with ITC transferability inside the stack and a three-month finance-to-COD window. Moment Energy notched a world-first UL safety certification for a second-life BMS, formalizing one of the few legitimate non-Chinese cell supply paths under the new FEOC material-assistance regime. And an independent lab found hexavalent chromium and arsenic in discharge from Tesla's Robstown lithium refinery, the most prominent US-domiciled lithium hydroxide facility, with the state's permit and prior investigation both missing the relevant analytes. Cross-vertical thread: AI-driven hyperscale load is now visible inside the same week across nuclear consolidation, PJM queue intake, and ERCOT BESS capital stacks, with the policy stack (FEOC, IRA transferability, FERC queue discipline) doing exactly the routing work it was designed to do.

US battery storage hit a record 9.7 GWh in Q1 2026, with 71% of utility-scale capacity going up in red states

SEIA and Benchmark Mineral Intelligence reported Q1 2026 US energy storage installations at 9.7 GWh, the strongest first quarter on record and a 32% year-over-year gain. Utility-scale accounted for 7.8 GWh of that. Texas, Arizona, and California led; together with the next handful of conservative-leaning states they hold 71% of utility-scale installs, even as federal policy uncertainty grows.

Frequently asked

Why not just read general energy news?

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.

Is this for traders or long-horizon investors?

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.

What verticals do you cover and how do they connect?

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.

What's your stance on climate change?

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.

What's your analytical frame across verticals?

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.
