Two new storage solicitations show how battery buying is becoming routine utility planning in very different power markets. Appalachian Power is seeking up to 800 MW of battery energy storage in Virginia through two requests for proposals, while Central Coast Community Energy, known as 3CE, is looking for renewable and storage resources in California's CAISO market. The common thread is not chemistry hype or a single project announcement. It is procurement discipline. Buyers are asking for projects with site control, interconnection progress, defined commercial dates, four-hour duration, resource adequacy value, and contracts that can survive utility and regulatory review. AI-generated image Virginia storage procurement is moving from policy target to project screening, with data-center load raising the stakes for reliability. 800 MW APCo storage sought 500 MW purchase and sale track 300 MW capacity purchase track 4 hr 3CE storage floor Virginia storage moves into execution mode Appalachian Power's Virginia solicitation has two tracks. One asks for up to 500 MW of battery energy storage through purchase and sale agreements that would transfer full equity interest in a project company. The other asks for up to 300 MW through capacity purchase agreements. The company issued both on August 17, with proposals due September 30, 2026. The requirements are pointed. Development-stage bids need full site control, cured land title defects, executed interconnection and construction services agreements where applicable, preliminary engineering, a permitting plan, and a Phase I environmental site assessment. Build-transfer projects must be complete, commercially operable facilities able to deliver into PJM or Appalachian Power's distribution system by an expected commercial operation date of December 15, 2030, although later dates may still be considered. Those conditions matter because Virginia is no longer asking whether storage belongs on the grid. The question is which projects can be built, interconnected, financed, and owned under utility oversight. The state's updated storage requirements have Appalachian Power seeking approval for 780 MW of short-duration storage by 2040 and 520 MW of long-duration storage by 2045. Dominion Energy has a much larger target, with 16 GW of short-duration storage and 3.48 GW of long-duration storage by 2045 under the new legislative framework described by Energy-Storage.news.

PJM demand pressure gives the RFP more weight Virginia sits inside PJM, the largest organized wholesale power market in the United States. That makes Appalachian Power's battery procurement part of a larger resource adequacy debate. Northern Virginia's data-center buildout is pushing load growth into utility planning, and PJM has spent 2026 working through market design questions tied to reliability, new large loads, capacity accreditation, and faster resource entry. Batteries are not baseload power plants, and they do not solve every capacity problem. They can, however, move energy into stressed hours, support local reliability, reduce transmission congestion in some cases, and offer fast response for grid operators. In a market wrestling with demand growth, retirements, interconnection delays, and capacity prices, short-duration batteries can become part of the resource adequacy toolkit. The commercial details will decide how much value APCo can capture. Standalone storage earns money only when market rules, capacity accreditation, dispatch rights, operating constraints, and contract structures line up. A capacity purchase agreement can shift some project risk away from outright utility ownership, while a purchase and sale agreement gives the utility more control over the asset. The dual structure lets APCo test both approaches without betting the entire procurement on one contract form. What developers should notice The RFP is asking for mature projects. Site control, interconnection status, permits, tax-credit eligibility, and a credible operating date may carry as much weight as battery pricing. California's 3CE wants flexibility, not just clean energy On the West Coast, 3CE's clean energy and reliability RFP is built around a wider menu. The community choice aggregator is seeking offers of at least 20 MW across renewable generation, renewable generation paired with storage, standalone storage, resource adequacy contracts, and carbon-free or low-carbon generation. Storage paired with renewables must have at least four hours of duration, and standalone storage must also meet a four-hour minimum. The procurement is not limited to conventional lithium-ion systems. 3CE said it is interested in storage technologies that support its innovation goals, which leaves room for alternative chemistries or other formats if they can meet contract and reliability needs. Offers are due September 25, 2026, and power purchase agreement start dates must be no later than December 31, 2032, with preference for projects that reach commercial operation before 2030. California's need looks different from Virginia's, but the destination is similar. CAISO already has a large battery fleet that charges during solar-heavy hours and discharges into the evening ramp. Community choice aggregators still need renewable portfolio standard compliance, carbon-free procurement, and resource adequacy. Four-hour storage remains the workhorse product because it fits evening net-load patterns and capacity requirements better than shorter systems.

One procurement story, two market signals Taken together, the APCo and 3CE solicitations show the split personality of the U.S. storage market. In Virginia, batteries are being pulled by utility planning, data-center demand, and a legal requirement to add storage capacity over time. In California, storage is tied to a market that already depends on batteries, but still needs more contracted capacity to firm renewable energy and meet reliability obligations. The scale also shows how batteries are moving out of the pilot category. An 800 MW Virginia solicitation is large enough to affect developer pipelines. A California RFP that allows standalone storage, renewable-plus-storage, and resource adequacy products gives sellers several ways to monetize the same underlying flexibility. These are not science projects. They are procurement screens for assets that must pass interconnection, financing, tax, operational, and regulatory tests. Battery suppliers should read the signals carefully. Utilities and community choice buyers are not only looking for containers and cells. They are looking for warranties, system integration, controls, availability guarantees, fire safety documentation, domestic-content clarity, service commitments, and the ability to hit contract dates. As more projects compete for the same grid windows, the soft parts of a bid become hard differentiators. AI-generated image The next storage bottleneck may be project maturity: land, interconnection, permitting, and contract readiness. What to watch next The first item is bid quality. If developers can offer mature Virginia projects with site control and interconnection agreements, APCo will have a clearer path to regulatory approval. If the response is thin, the RFP will show that storage targets are easier to write than to fill with buildable assets. The second item is contract structure. Capacity purchase agreements may appeal to developers that want to retain ownership, while purchase and sale agreements may suit projects already designed for utility acquisition. In California, 3CE's category mix will test whether standalone storage can compete with renewable-plus-storage deals and resource adequacy-only offers in the same proc
