Maryland's first bulk storage procurement lands 440 MW — barely half its target

8 min read
TODAY'S LEAD: The shortfall, caused by persistent interconnection constraints in PJM territory, signals that even states writing big checks for batteries may not be able to buy their way past grid bottlenecks.

KEY DEVELOPMENTS

  • Maryland Storage Procurement Misses 800 MW Goal: The state's inaugural bulk energy storage solicitation under the Next Generation Energy Act secured 440 MW / 1,760 MWh — roughly 55% of its 800 MW target — with PJM Interconnection capacity constraints cited as the limiting factor.

Solar & Storage

The biggest construction start of the day belongs to Clearway Energy Group, which broke ground on the 650 MW Swan Energy Center in Bates County, Missouri. The project occupies reclaimed strip-mine land — a siting strategy that sidesteps the farmland-conversion fights plaguing solar developers across the Midwest. Clearway secured financing and locked in a 20-year power purchase agreement, and the project marks the company's entry into Missouri, a state that has lagged its neighbors in utility-scale solar deployment. For developers scouting brownfield and post-industrial sites, Swan Energy Center is the clearest proof yet that mined-out land can anchor a bankable, large-scale project.

Out west, the scale race continues. AES's Bellefield Solar project near Mojave, California, pairs 641 MWdc of generation with 500 MW of battery storage in its first phase, with Primoris Renewable Energy serving as EPC contractor. The project, nominated for a 2026 Project of the Year award by Solar Builder, reflects the hybrid solar-plus-storage model that California's grid increasingly demands. Projects of this size now define the state's procurement pipeline, and the storage component directly addresses the duck-curve curtailment risk that has dogged afternoon solar generation for years.

Meanwhile, a different kind of innovation is taking shape in Michigan. Ann Arbor's Sustainable Energy Utility deployed 360 kW of solar and 920 kWh of battery storage across more than 80 homes in the city's Bryant neighborhood — a pilot that makes Ann Arbor the first city-owned utility in the country to directly purchase and install residential solar-plus-storage for energy-burdened households. The model bypasses the traditional rooftop-solar financing stack entirely: the city owns the hardware. If replicable, it offers municipalities a template for reaching low-income customers who have been largely shut out of distributed solar.

Smaller projects are proving the technology's versatility in unexpected places. In Florida, D3Energy energized a 1.4 MW floating solar photovoltaic system at Universal's Epic Universe theme park in Orlando — one of three on-site renewable installations at the park. And in remote southeastern Utah, Obodo Energy Partners upgraded Cal Black Memorial Airport's off-grid power system to 40 kW solar with 200 kWh of battery storage, addressing rising electrical demand at the FAA-operated facility near Lake Powell. Both projects illustrate how solar and storage are filling niches — floating arrays on constrained urban sites, off-grid microgrids at rural airports — that barely registered as markets five years ago.

The battery storage sector notched a speed record in Texas. SMT Energy's Houston IV project reached its full 160 MW / 320 MWh capacity after just six weeks of commissioning, using FlexGen's HybridOS energy management platform. That timeline matters: commissioning bottlenecks have been a persistent drag on storage deployment nationwide, and a six-week turnaround — if reproducible — could meaningfully accelerate project timelines across ERCOT and other markets. The project follows several other Texas battery announcements in recent days, including Linea Energy's 250 MW / 500 MWh Mesa View project that closed financing earlier this week.

But the day's most consequential storage story came from Maryland, where the state's first bulk energy storage procurement under the Next Generation Energy Act landed 440 MW / 1,760 MWh — well short of the 800 MW target. The culprit: capacity constraints within PJM Interconnection, the regional grid operator whose queue delays have become a chokepoint for clean energy across the mid-Atlantic and Midwest. Maryland set an ambitious procurement target, found willing developers and willing capital, and still couldn't fill the order. That gap is a warning to every state banking on storage to meet reliability and decarbonization goals simultaneously. Read More: landed 440 MW / 1,760 MWh.

Policy & Markets

A bipartisan group of U.S. senators introduced the American Affordability and Jobs Act of 2026, a permitting reform bill aimed at speeding environmental review and approval for solar and other energy projects. The legislation preserves tribal consultation rights and environmental protections while attempting to shorten the timeline from application to shovel. This is the latest iteration of a permitting push that has been building momentum on Capitol Hill; as covered in earlier briefings this week, a separate bipartisan permitting bill is already drawing mixed reviews from clean energy groups concerned about provisions that could also accelerate fossil fuel infrastructure.

In Illinois, ComEd signaled it will file a virtual power plant framework by the end of 2027 — a proposal that would go beyond batteries to integrate a range of distributed energy resources into a customer-centered grid model. The filing timeline is still more than a year away, but the announcement puts Illinois utilities and regulators on notice that VPP architecture is coming. For developers of residential solar, home batteries, and demand-response technology, ComEd's framework could define how distributed assets get compensated — and who controls dispatch — across one of the Midwest's largest service territories.

On the less conventional end of the spectrum, Fit Energy received zoning approval from Newport Township in Luzerne County, Pennsylvania, for a gas-powered fuel cell and data center project. The company is now advancing through engineering and permitting. Gas-fueled fuel cells occupy an awkward space in clean energy taxonomy — cleaner than combustion turbines, but still reliant on natural gas — and the project reflects the intense pressure data center demand is putting on local power systems, a theme that has surfaced repeatedly in recent weeks.

LOOKING AHEAD

  • Senate Permitting Reform Trajectory: With two separate bipartisan permitting bills now in play, watch for committee markups and whether the proposals get consolidated — the outcome will shape project timelines for solar, wind, and storage developers for years.
  • PJM Queue Reforms Under Pressure: Maryland's storage procurement shortfall puts a spotlight on PJM's interconnection backlog; developers with projects in the queue should track whether the regional grid operator accelerates its transition study process in response.
  • ComEd VPP Framework Details: Illinois stakeholders will be watching for specifics on how ComEd's virtual power plant proposal defines eligible resources and compensation structures ahead of the planned filing by end of 2027.

TODAY'S QUICK ANSWERS

Q: What does Maryland's storage procurement shortfall mean for other states with ambitious battery targets?

A: It means that state mandates and willing capital aren't enough if the interconnection queue can't deliver. Maryland aimed for 800 MW and got 440 MW — a 45% miss driven by PJM grid constraints that affect a dozen states. Any state in PJM territory with large storage procurement goals should expect similar friction unless queue reform accelerates.

Q: Why should developers pay attention to SMT Energy's six-week commissioning timeline in Texas?

A: Because commissioning has been one of the least predictable phases of battery deployment, often stretching months. A repeatable six-week timeline on a 160 MW / 320 MWh system — achieved with FlexGen's software platform — could compress project schedules enough to change the economics of merchant storage in ERCOT, where capturing seasonal price spikes depends on hitting commercial operation dates precisely.

Q: What makes the Clearway Missouri project notable beyond its 650 MW size?

A: Two things. First, it's built on reclaimed strip-mine land, offering a replicable siting model in coal country that avoids agricultural land-use conflicts. Second, it's Clearway's first Missouri project, suggesting the state's solar market has reached the scale and policy stability needed to attract major national developers with 20-year PPA commitments.

THE BOTTOM LINE: Grid interconnection constraints — not capital, not policy, not technology — are now the binding constraint on U.S. clean energy deployment, and Maryland's storage procurement miss is the starkest evidence yet that the bottleneck is costing states real megawatts.
