North Carolina legislators are advancing the Ratepayer Protection Act

9 min read
TODAY'S LEAD: North Carolina legislators are advancing the Ratepayer Protection Act, a sweeping energy bill that would regulate data center power consumption while simultaneously incentivizing fossil fuel generation — a move that could reshape the state's clean energy trajectory just as utilities scramble to meet surging electricity demand. The bill arrives as states nationwide grapple with the collision between data center growth and grid reliability, days after New York passed the nation's first data center moratorium.

Policy & Markets

North Carolina is emerging as the latest — and perhaps most consequential — battleground in the national fight over how to power America's data center boom. The state's Ratepayer Protection Act, analyzed this weekend by Inside Climate News, takes a strikingly different approach from New York's outright moratorium passed just last week. Rather than freezing development, North Carolina's bill aims to regulate how much energy data centers can draw from the grid while creating financial incentives for fossil fuel generation to meet the remaining demand — a combination that clean energy advocates describe as "the terrible combined with the good."

The legislation matters enormously for the state's robust utility-scale solar pipeline. North Carolina ranks among the top five states for installed solar capacity, and developers have been banking on data center demand to justify new renewable energy projects. If the bill steers utilities toward gas-fired generation instead, it could undercut the economics of planned solar and battery storage installations across the Piedmont and Coastal Plain regions. Duke Energy, the state's dominant utility, has been at the center of debates over its generation mix as it navigates the retirement of coal plants and the buildout of new capacity.

The North Carolina bill represents a growing trend: states are no longer treating data center growth as an unalloyed economic good. New York's moratorium, Colorado's rejection of Xcel Energy's $2.9 billion gas infrastructure plan, and now North Carolina's hybrid approach all reflect the tension between accommodating explosive electricity demand growth and maintaining grid affordability and clean energy goals. For the Trump administration, which has generally favored removing permitting barriers for both fossil fuel and data center development, this patchwork of state responses creates a complex landscape. Federal energy policy under the current administration has prioritized reliability and baseload generation, which aligns with the fossil fuel incentive portions of North Carolina's bill but clashes with the regulatory constraints on data center consumption.

Meanwhile, the crisis at Lake Mead is adding urgency to clean energy planning across the American West. Top hydrologists and water policy experts told the Las Vegas Review-Journal that the reservoir is declining toward "system crash" faster than previously modeled, with implications that extend far beyond water supply. Hoover Dam's generating capacity has already been significantly curtailed by low water levels, and further declines could eliminate it as a power source entirely — removing roughly 2,000 MW of clean, dispatchable generation from the Western grid.

The Lake Mead warning lands at a precarious moment for the Colorado River Basin states. Nevada, Arizona, and California are locked in contentious negotiations over post-2026 operating guidelines for the river, and the new expert assessments suggest that even aggressive conservation targets may be insufficient. For the clean energy industry, the hydropower losses are forcing utilities to accelerate procurement of alternative generation — primarily utility-scale solar and battery storage — to fill the gap. Arizona Public Service and NV Energy have both announced major solar-plus-storage solicitations in recent months, in part to hedge against continued hydroelectric declines.

Solar & Storage

While no major new utility-scale solar project announcements broke over the weekend, the policy developments in North Carolina and the Western water crisis are reshaping the competitive landscape for solar and battery storage developers. North Carolina's bill, if enacted, could slow the interconnection of new solar projects by redirecting utility investment toward gas plants. That would be a significant blow in a state where solar developers have already faced extended interconnection queues and rising costs associated with grid upgrades.

On the technology front, CATL's announcement that it is developing a lithium-air battery with a theoretical energy density of up to 12,000 Wh per kilogram deserves attention — though with significant caveats. As CleanTechnica reported, that figure represents roughly a 50-fold improvement over the best commercial lithium-ion cells available today, which typically deliver 250–300 Wh/kg. Lithium-air chemistry has long been considered a "holy grail" of battery research, but it faces severe practical challenges: cycle life, air electrode degradation, and sensitivity to moisture have kept it largely confined to laboratories. Read More: CleanTechnica.

For the American energy storage industry, CATL's push is both a competitive threat and a potential catalyst. U.S. battery manufacturers, including the newly merged T1 Energy-KORE Power entity profiled in last week's briefing, are focused on scaling current lithium-iron-phosphate and nickel-manganese-cobalt chemistries for grid-scale storage. If CATL achieves even a fraction of its lithium-air targets at commercial scale, it could widen the technology gap between Chinese and American battery makers — intensifying calls for more aggressive domestic manufacturing policy. The Trump administration's tariffs on Chinese battery imports have so far shielded U.S. manufacturers, but they haven't closed the underlying R&D gap that CATL's announcement underscores.

Wind Energy

No significant new wind project developments were reported over the weekend, but the sector remains in a holding pattern shaped by federal policy uncertainty. The industry continues to watch for signals from the Trump administration on offshore wind lease terms and permitting timelines, particularly for projects in the New York Bight and along the Atlantic Coast. Onshore wind, which accounted for a significant share of the nearly 28 GW of new generation capacity added in the six months through March 2026, continues to advance in the Great Plains and Texas but faces headwinds from local opposition and transmission constraints in the Midwest.

The Google-Intersect Meitner Energy Center in the Texas Panhandle, reported on last week, remains the most ambitious integrated wind-solar-storage project in development, with over 1 GW of planned capacity. Its progress will serve as a bellwether for whether co-located renewable energy-data center complexes can bypass the grid bottlenecks that have stalled standalone projects elsewhere.

LOOKING AHEAD

  • North Carolina Legislative Calendar: Watch for committee votes on the Ratepayer Protection Act this week, with clean energy industry groups expected to mount an aggressive lobbying push to strip or modify the fossil fuel incentive provisions.
  • Colorado River Negotiations: Basin states face a critical round of talks on post-2026 operating guidelines; any failure to reach agreement could trigger federal intervention and further hydropower curtailments affecting Western grid planning.
  • Colombia Runoff Results: Sunday's presidential election could shift Latin America's largest remaining fossil fuel development policies, with potential ripple effects on global oil markets and U.S. energy export competitiveness. Read More: presidential election.

TODAY'S QUICK ANSWERS

Q: What does North Carolina's Ratepayer Protection Act mean for solar developers with projects in the state's pipeline?

A: It's a yellow flag, not a red one — yet. The bill doesn't ban solar development, but by creating financial incentives for fossil generation to meet data center demand, it could redirect utility procurement away from planned solar-plus-storage projects. Developers with interconnection agreements already in hand are likely safe, but those in earlier stages should watch committee markups closely. North Carolina has roughly 10 GW of solar installed; the bill could slow the path to the next 10 GW significantly.

Q: Why should clean energy executives care about Lake Mead's decline?

A: Because every megawatt of lost hydropower at Hoover Dam is a megawatt that Western utilities must replace — and they're increasingly turning to solar and battery storage to do it. If Lake Mead hits "system crash" levels, the region could lose up to 2,000 MW of dispatchable clean generation, creating urgent procurement opportunities for developers with shovel-ready projects in Nevada, Arizona, and Southern California. It also strengthens the case for long-duration energy storage to replace hydro's role as a grid-balancing resource.

Q: Should U.S. battery manufacturers worry about CATL's lithium-air breakthrough?

A: Not immediately, but strategically, yes. Lithium-air technology is likely a decade or more from commercial viability, and CATL's 12,000 Wh/kg figure is a theoretical ceiling, not a product spec. However, the announcement signals that CATL is investing heavily in next-generation chemistries while most U.S. manufacturers are still scaling current technology. American firms and policymakers should treat this as a reminder that tariffs alone won't ensure long-term competitiveness — sustained R&D investment is essential.

THE BOTTOM LINE: The data center energy battle is fracturing along state lines — with North Carolina favoring fossil incentives and New York choosing moratoriums — and clean energy developers need state-by-state strategies, not a one-size-fits-all playbook, to navigate the most consequential demand growth opportunity in a generation.
