MP Materials investor release, Q2 2026 earningsus-supply

MP Materials swings to positive adjusted EBITDA as NdPr sales more than double

The only fully integrated US rare earth producer posted $108.5M in Q2 revenue, adjusted EBITDA of $28.5M, and 1,006 metric tons of NdPr sales, up 127% year over year. The Independence magnet facility is now in commercial production and a new samarium oxide line for the Department of War is on the roadmap.

XPLR forms Mammoth Plains and Carousel storage JVs with NextEra, funds equity via interconnection sales

XPLR Infrastructure disclosed in its Q2 2026 8-K that it formed two battery storage joint ventures with NextEra Energy Resources in July, Mammoth Plains and Carousel, and completed the sale of the associated surplus interconnection rights. The two projects are part of a four-project co-investment adding roughly 200 net MW of battery capacity by year-end 2027, with XPLR holding a 49% interest and net equity of approximately $80 million. Earliest construction start is Q4 2026, with the bulk of activity in 2027. Management guided to at-least-double-digit equity returns. The structure is a template for how surplus interconnection rights, not new queue positions, become the near-term unlock for US storage buildout.

FERC large-load show cause: abeyance window closes, Aug 17 filing wall next

The 45-day abeyance window under FERC's six show-cause orders (EL26-67 through EL26-72) closed Sunday. Any RTO that did not file for a stay by Aug 3 must submit its full Section 206 answer or Section 205 tariff reforms by Aug 17. The docket is the near-term inflection point for how PJM, MISO, SPP, CAISO, ISO-NE, and NYISO study, price, and interconnect large loads. Data center queue economics, co-location rules, and cost-shift protections all land in the same brief.

Sonnedix closes €730M solar-plus-storage refinance across four southern-European markets

A nine-bank consortium backed Sonnedix's refinancing of ~540 MW of operating PV plus two BESS assets across Italy, Spain, Portugal and France, with proceeds also earmarked for new PV and battery construction. The scale, syndicate breadth, and battery-inclusion signal that European solar-plus-storage project finance has fully recovered from the 2023-24 crunch, with lithium-backed BESS now bundled as standard collateral rather than optional add-on.

DOE names Nvidia, AWS, and six reactor firms to $60M Project Prometheus

The Department of Energy's Genesis Mission awarded a three-year, $60M Phase II grant to Project Prometheus, an AI-for-reactor-design program led by Idaho National Laboratory with Nvidia and Amazon Web Services. X-energy, Oklo, TerraPower, Westinghouse, Aalo Atomics, and Standard Nuclear are named participants. NuScale was not selected.

Terra-Gen closes out 365-MW Lockhart complex with 80-MW final phase in San Bernardino County

Terra-Gen brought the 80-MW Lockhart Solar PV IV online in mid-July, completing a 365-MW solar plus 173.7-MW battery buildout at the Kramer Junction interconnect. All four phases now sell under long-term PPAs to California load-serving entities. Cupertino Electric was the EPC. The complex is jointly owned by Masdar and Igneo Infrastructure Partners.

The August 17 FERC large-load filing wall: a six-RTO reading map for the Section 205 versus Section 206 split

August 17, 2026 is the deadline for the six RTOs and ISOs (PJM, MISO, SPP, CAISO, ISO-NE, NYISO) to file either voluntary Section 205 tariff reforms or answers under Section 206 in the FERC large-load show-cause dockets (EL26-67 through EL26-72). The five reform areas the Commission flagged (application and study processes, cost-shift protections, co-location rates, flexible-load and behind-the-meter services, and electrically proximate interconnection) will be answered on very different postures depending on which RTO takes the lead. The Section 205 versus Section 206 split by August 17 tells the market which regions plan to write their own large-load rulebook and which will accept a Commission-imposed one, and that split determines the interconnection-revenue pull for the next twelve to eighteen months of hyperscaler and industrial siting decisions.

The OBBBA bucket-two 5% safe harbor documentation set that interconnection customers need on file by December 31, 2026 to preserve the four-year continuity presumption.

OBBBA bucket-two, the tranche of solar and wind projects that began construction between January 1, 2026 and July 4, 2026, has a placed-in-service deadline of December 31, 2030 under the four-year continuity safe harbor. The Treasury's Notice 2025-42 continues the 5% expenditure test as one of the two beginning-of-construction methods, and the documentation package that supports the 5% election is what carries the four-year presumption on audit. The checklist has five categories: master supply agreements dated in the bucket-two window, transferred title on components equal to at least 5% of the total project cost basis, delivery or storage records for the transferred components, a project cost basis worksheet locked to the beginning-of-construction date, and continuous efforts evidence dated to each intervening year through placed-in-service. The December 31, 2026 date is not a Treasury filing deadline. It is the internal documentation-completion date that project sponsors and their tax counsel are working to before the FY2027 audit cycle opens on 2026 returns.

High-voltage transmission substation and interconnection equipment, standing in for the PJM expedited interconnection process approved by FERC in June 2026 for up to ten large new or uprated capacity resource requests per calendar year through the December 31, 2027 sunset.

PJM's expedited interconnection window, capped at ten large capacity requests per year and sunsetting December 31, 2027, is the second grid-side filter overlaying the OBBBA bucket-two solar and wind pipeline.

FERC's June 9, 2026 order in Docket ER26-1563 accepted PJM's expedited interconnection process for large new or uprated capacity resources. The mechanism approves up to ten interconnection requests per calendar year outside the reformed cluster study cycle and sunsets on December 31, 2027. The eligible pool is dispatchable capacity: gas combined-cycle, gas combustion turbine, coal life extension, nuclear uprate. Solar and wind are not the target. The relevance to the OBBBA bucket-two pipeline is second-order, on the network upgrade cost allocation and study queue capacity that the expedited window pulls off the top before the reformed cluster gets to run.

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.
