TODAY'S LEAD: New Jersey Governor Mikie Sherrill signed legislation lifting the state's decades-old de facto moratorium on new nuclear power plants, making the Garden State the latest to bet on atomic energy as soaring electricity demand and climate targets collide. Meanwhile, California's battery storage fleet is fundamentally rewriting the economics of solar power, with storage systems boosting midday solar revenues by up to $42 per megawatt-hour.

Solar & Storage

California's battery storage fleet has crossed a threshold that developers and grid planners have long anticipated: storage is no longer just a grid reliability tool — it is actively reshaping the economics of solar generation. According to PV Magazine, more than 3 GW of energy storage operating in the CAISO market is now absorbing cheap midday solar electricity and discharging it during higher-priced evening hours, lifting the value of negatively priced solar power by as much as $42 per megawatt-hour. On March 20 alone, batteries purchased 52,777 MWh of solar energy and delivered an estimated $2.2 million premium to generators — a vivid proof point that solar-plus-storage economics have arrived at scale.

But the road to deploying more storage isn't smooth everywhere. In Escondido, California, near San Diego, AES Corp. pulled the plug on its proposed Seguro grid battery storage project after sustained opposition from residents who objected to siting a utility-scale battery system near homes and a hospital. The withdrawal is the latest example of a pattern becoming familiar across the country: even as policymakers push aggressively for storage deployment, the local politics of siting these facilities remain a formidable barrier. Community concerns about safety, noise, and property values continue to stall or kill projects that utilities and grid operators say are essential.

This tension is playing out against a backdrop of states racing to build storage capacity. In Minnesota, the Public Utilities Commission approved Xcel Energy's CapacityConnect Phase 2 program, authorizing 50 to 200 MW of utility-owned battery storage while establishing a new framework for valuing distributed energy resources. Notably, the commission deferred decisions on virtual power plants, requiring Xcel to submit comprehensive evaluation plans by November 2027. The split decision signals that regulators are increasingly comfortable with utility-scale batteries but still wrestling with how to integrate more decentralized storage models into grid planning.

On the solar side, Cook County, Illinois, celebrated the completion of a 1.3-MW solar installation at its Skokie courthouse, installed by Ameresco as part of the county's broader climate mitigation goals. While modest in scale compared to utility-scale plants, the project underscores the growing role that municipal and county governments are playing as direct solar adopters — not just as permitting authorities, but as customers.

California's solar landscape, however, faces a cloudier outlook on the community solar front. The state's Public Utilities Commission issued a proposed decision on community solar that clean energy advocates have sharply criticized as a development killer. CleanTechnica reports that advocates argue the decision will effectively prevent new community solar projects from penciling out financially, particularly harming lower-income Californians who stand to benefit most from shared solar programs. The criticism comes at a time when California's influence on national solar policy remains outsized — as PV Tech notes, the state's rooftop solar industry challenges and evolving stance on virtual power plants and balcony solar tend to set trends that ripple across other state markets.

Wind Energy

Wind energy news was quiet on the domestic front today, though internationally, Chile's government approved three new large-scale wind farms as part of a broader permitting acceleration push, according to Wind Power Monthly. Stateside, the industry continues to navigate an uncertain federal policy environment under the Trump administration, with developers closely watching how tariff policies on imported steel and aluminum — reaffirmed earlier this week — will affect turbine component costs through the rest of 2026.

Policy & Markets

New Jersey made the biggest policy splash of the day. Governor Mikie Sherrill's signing of legislation to end the state's de facto moratorium on new nuclear power plants marks a significant shift for the Garden State, which has long relied on its existing fleet of reactors but blocked new construction through coastal permitting restrictions. By modifying requirements under the Coastal Area Facility Review Act, the law opens a regulatory pathway for advanced reactor technologies at a moment when data center-driven electricity demand is putting enormous pressure on grids up and down the Eastern Seaboard. New Jersey joins a growing list of states reconsidering nuclear as part of the clean energy mix.

In Annapolis, Maryland legislators are sprinting to finalize the Utility RELIEF Act before their session ends Monday. House and Senate leaders announced an agreement on the comprehensive energy package, which targets lower utility costs and improved grid reliability. The deal must clear both chambers and reach Governor Wes Moore's desk within days, making this a story to watch closely heading into the weekend.

Out West, Arizona's Energy Promise Taskforce delivered one of the most ambitious grid modernization roadmaps seen from a state body this year. The 31-recommendation plan centers on virtual power plants and distributed solar to address a projected 40% growth in peak electricity demand — a figure driven largely by industrial expansion and cooling loads in the Sun Belt. The taskforce called for 2,000 MW of battery storage and streamlined permitting for renewable projects, positioning Arizona as a potential model for other high-growth states grappling with the same demand surge.

LOOKING AHEAD

Maryland Legislative Deadline: Both chambers must pass the Utility RELIEF Act by Monday's session close, setting up a frenetic weekend of potential amendments and floor votes in Annapolis.
CPUC Community Solar Fallout: Expect solar industry groups and environmental justice advocates to mount a formal challenge to California's proposed community solar decision in the coming weeks, with potential implications for programs in other states.
Minnesota VPP Framework: With the PUC deferring virtual power plant decisions until Xcel submits evaluation plans by November 2027, stakeholders should watch for interim guidance that could shape how other Midwest utilities approach distributed storage.

Today's Quick Answers

Q: What does California's battery storage impact on solar pricing mean for developers in other markets?

A: It's a proof of concept that should accelerate co-located solar-plus-storage development nationwide. When batteries can add $42/MWh in value to solar output and deliver $2.2 million in premium revenues in a single day, the business case for pairing storage with solar farms becomes nearly irresistible — particularly in markets with growing midday curtailment. Developers in ERCOT, PJM, and SPP should take note: as storage penetration grows, the old model of selling solar at depressed midday prices is giving way to a storage-arbitrage premium.

Q: Why does AES pulling out of the Escondido battery project matter beyond one canceled deal?

A: It highlights a systemic challenge: states are setting aggressive storage targets — Arizona alone wants 2,000 MW — but community opposition to siting is becoming the binding constraint. Developers need to invest earlier and more heavily in community engagement, and policymakers may need to establish clearer siting frameworks for battery projects the same way they have for other critical infrastructure. Without that, the gap between storage targets and actual deployment will only widen.

Q: What should clean energy executives watch for in New Jersey's nuclear reopening?

A: The immediate signal is demand-driven. New Jersey's move reflects the same electricity demand pressures — data centers, electrification, industrial load — pushing states to reconsider every carbon-free generation source available. For solar and storage developers, this isn't necessarily competition; it's a sign that the demand growth opportunity is large enough to support multiple technologies. Watch for advanced reactor developers to target New Jersey for demonstration projects within the next 12 to 18 months.

THE BOTTOM LINE: Today's news makes one thing unmistakably clear — the demand for clean electricity is outpacing the infrastructure to deliver it, and the states moving fastest on storage, nuclear, and grid modernization are the ones that will define the competitive landscape for the rest of the decade.
