Solar & Storage
Northern Colorado now hosts its largest solar installation. The 324-MW Black Hollow Sun project near Severance reached full commercial operation with the completion of its second phase, developed by ContourGlobal for the Platte River Power Authority. The project, which began development in 2019, supplies power to the municipal utility that serves Fort Collins, Loveland, Longmont, and Estes Park — a region where data center inquiries and population growth have tightened the supply picture. For municipal utilities watching load growth accelerate, a seven-year development timeline from contract to completion is a sobering data point.
In the Southwest Power Pool footprint, the Texas PUC's approval of Southwestern Public Service Company's Tolk coal plant closure clears the path for replacement renewable energy and battery storage capacity near Lubbock. The decision is notable for its water calculus: the Tolk plant consumed millions of gallons annually for cooling in a region of the Texas Panhandle where the Ogallala Aquifer is under severe stress. Developers watching SPP's resource adequacy debates will note that the commission framed the coal-to-renewables swap partly as a water conservation measure — a rationale that could surface in other arid Western states evaluating thermal plant retirements.
Smaller-scale solar continues to prove durable against headwinds. U.S. small-scale solar added 1.6 GW in the second quarter of 2026, and when combined with utility-scale solar, the technology accounted for 55% of all new electric generating capacity in the period, according to PV Magazine USA. Distributed battery storage surged alongside it, with over 2.5 GWh of behind-the-meter capacity added in Q2 alone. Transmission bottlenecks continue to stall larger projects, effectively redirecting capital toward rooftop and community-scale installations that don't require interconnection queue positions.

That residential storage trend has legs. Full-year 2025 data shows 37% of new home solar systems included a battery, up from 25% in 2024. California's Net Billing Tariff — which sharply reduced export compensation for solar-only systems — was the primary accelerant, but Arizona and Texas posted rapid gains as well, driven by rising retail rates and grid reliability concerns. Hawaii maintained the nation's highest attachment rate. For storage manufacturers and installers, the near-doubling in one year suggests that battery economics have crossed a threshold where storage is becoming a default rather than an upsell.
In Delaware, TurningPoint Energy energized a 2.1-MWac community solar project in Georgetown, the third installation in the company's 30-MWdc Delaware portfolio, according to PV Tech. The project is a modest addition by megawatt count but matters in a state where community solar is still building critical mass. Meanwhile, strategic partnerships are beginning to recast battery energy storage as core infrastructure rather than a speculative financial asset, a framing shift that, if it holds, could unlock cheaper project finance terms and longer-duration investment horizons.

Policy & Markets
The fight over federal farm solar funding escalated sharply this week. USDA updated its REAP grant eligibility to exclude solar projects on farmland — a program that had provided grants covering 25% of project costs for rural farmers and small business owners. Within a day of that rule change becoming public, the Iowa Farmers Union and a solar advocacy group filed suit, alleging the new rules were applied retroactively to projects in Iowa that had already been selected for funding and begun construction. The case will test whether USDA can claw back commitments mid-stream — a question with direct financial consequences for rural developers who underwrote projects assuming the 25% grant. Read More: filed suit.
On Capitol Hill, the Bipartisan American Affordability and Jobs Act of 2026 moved from closed-door negotiation to formal introduction. This briefing flagged the deal's outlines yesterday; the newly public bill text targets electric transmission permitting, interconnection queue reform, and broader infrastructure approval timelines. Industry survey data cited alongside the introduction found that 94% of delayed clean energy projects blamed federal permitting, with developers reporting cost increases of 6–10% on projects in the 100-MW range. Environmental groups and industry lobbyists are already clashing over the bill's tradeoffs, setting up a contentious markup. For developers and investors, the bill's treatment of transmission siting authority and NEPA review timelines will determine whether it meaningfully shortens the years-long queue backlogs choking project pipelines.

Two state-level policy moves round out the picture. Virginia Gov. Abigail Spanberger released the state's energy plan, which prioritizes community solar, battery storage, and demand flexibility to meet net-zero goals by 2050 under the Virginia Clean Economy Act while accommodating surging data center load, according to Virginia Mercury. The plan's mixed-portfolio approach signals that the Spanberger administration sees electrification and load growth as complementary rather than conflicting priorities — a stance developers building in the PJM footprint will watch closely.

In California, Gov. Gavin Newsom signed bills advancing virtual power plants and balcony solar but vetoed community solar legislation. The VPP bill matters because California's record-setting virtual power plant dispatches — including the 580-MW event reported earlier this week — have relied on program structures that lacked permanent statutory backing. The community solar veto, however, keeps California as an outlier: most large states have community solar programs on the books. Developers targeting the state's low-and-moderate-income market will need to find alternative pathways.
LOOKING AHEAD
- REAP Lawsuit Timeline: The Iowa federal court case challenging USDA's retroactive REAP changes could produce an early injunction request, which would signal whether projects already under construction can retain their grant commitments while litigation proceeds.
- Senate Permitting Markup: Watch for committee scheduling of the Bipartisan American Affordability and Jobs Act; the speed at which leadership moves it to markup will indicate whether the bill has enough bipartisan support to advance before the lame-duck session.
- Virginia Energy Plan Implementation: Gov. Spanberger's plan sets broad targets, but the regulatory proceedings at the State Corporation Commission that translate policy into procurement orders and rate structures will determine how much new solar and storage capacity actually gets built.
TODAY'S QUICK ANSWERS
Q: What does the REAP lawsuit mean for rural solar developers outside Iowa?
A: If the court finds USDA improperly applied the farmland exclusion retroactively, it could block enforcement nationwide for projects already in the pipeline — preserving the 25% cost grant that made many small rural installations financially viable. Even if the ruling is narrow, the case creates legal uncertainty that will likely freeze new REAP-dependent solar investment until resolved.
Q: Why should investors care that residential storage attachment rates nearly doubled in one year?
A: The jump from 25% to 37% shows that home batteries are crossing from early-adopter territory into mainstream demand, driven by rate structures like California's Net Billing Tariff that penalize solar-only systems. For investors, the trend compresses payback periods for residential solar-plus-storage companies and expands the addressable market in states like Arizona and Texas that are adopting similar rate designs.
Q: What should developers watch in the Senate permitting bill's interconnection provisions?
A: The bill targets queue reform directly, and with 94% of delayed projects citing federal permitting as the bottleneck and cost increases running 6–10% on 100-MW installations, even modest timeline reductions translate into material savings. Developers should track whether the final text includes binding deadlines for interconnection studies or merely encourages process improvements — the difference determines whether queue wait times actually shrink.
THE BOTTOM LINE: Rural solar economics, residential storage adoption, and federal permitting timelines are all moving fast this week — but the REAP lawsuit and Senate bill will determine whether the policy scaffolding can keep pace with the market.
