The CPI Utility News Roundup: March 2026
March brought a month of milestones for the electric utility industry. From historic nuclear firsts to billion-dollar grid investments, the signals are clear: the industry is racing to meet surging demand while navigating a rapidly shifting policy and technology landscape. Here is what you need to know.
1. Big Tech Signs White House Pledge to Shield Ratepayers from Data Center Costs
What happened: Google, Microsoft, Meta, Oracle, xAI, OpenAI, and Amazon signed a White House "Ratepayer Protection Pledge" committing to fully cover the electricity costs of their AI data centers so that residential bills do not increase. The pledge requires companies to build, bring, or buy new generation resources and pay for all power delivery infrastructure upgrades required to service their facilities.
Why it matters: This is the clearest signal yet that political pressure around data center load growth has reached a tipping point. Data centers accounted for 63% of the capacity price surge in PJM's latest auction, adding $9.3 billion in costs, and over 300 data center bills have been introduced in more than 30 state legislatures in 2026. For utilities, the question is no longer whether big tech will pay its share, but how cost allocation frameworks will be restructured to enforce it.
Our take: The pledge has no binding enforcement mechanism, and the energy industry has largely greeted it with a shrug. The real test will be whether these commitments hold up in rate cases and interconnection agreements.

2. TerraPower Receives First-of-Its-Kind NRC Construction Permit for Advanced Reactor
What happened: On March 4, the Nuclear Regulatory Commission voted to issue a construction permit for TerraPower's Natrium reactor at the Kemmerer Power Station in Wyoming. This is the first commercial reactor construction permit in nearly a decade and the first ever for a non-light-water reactor. The 345 MW sodium-cooled fast reactor features a molten salt energy storage system capable of boosting output to 500 MW during peak demand.
Why it matters: This is a watershed moment for advanced nuclear in the United States. The NRC completed its safety review in just 18 months and 11% under budget, offering a template for how next-generation reactor licensing can work. With Meta simultaneously announcing an agreement with TerraPower for up to eight Natrium plants totaling 6.6 GW, the commercial pipeline for advanced nuclear is no longer theoretical. Construction has already begun, with commercial operation expected by 2030.
Our take: If TerraPower can deliver on cost and schedule at Kemmerer, it changes the math for every utility evaluating its long-term generation mix. The molten salt storage feature, which allows the plant to flex output, makes this more than just a baseload play.

3. DOE Launches $1.9 Billion SPARK Program for Grid Modernization
What happened: On March 12, the Department of Energy's Office of Electricity announced the SPARK funding opportunity, making $1.9 billion available from the Infrastructure Investment and Jobs Act. The program funds transmission reconductoring, advanced grid technologies, and cross-regional upgrades across three tracks: grid resilience (up to $427 million), smart grid (up to $614 million), and grid innovation (up to $862 million). Concept papers are due April 2.
Why it matters: This is the largest single grid modernization funding opportunity in recent memory and the third round under the GRIP program. With 55% of U.S. transformers now over 33 years old and 70% of transmission lines past the halfway point of their lifespans, the infrastructure need is urgent. SPARK funding could accelerate projects that would otherwise take years to move through traditional rate-case financing.
Our take: If your utility has been sitting on a transmission upgrade business case, the April 2 concept paper deadline is worth circling. Federal cost-sharing at this scale does not come around often.

4. Palisades Nuclear Plant Targets Late March for Historic Restart
What happened: The Palisades nuclear plant in southwest Michigan, the first decommissioned U.S. nuclear plant to attempt a restart, is now targeting late March 2026 to resume operations. The 800 MW plant is backed by $150 million in Michigan taxpayer funding and a $1.52 billion federal loan from the DOE. The timeline has been pushed back from late 2025 after inspections revealed cracked steam generator tubes and missing weld records.
Why it matters: If successful, Palisades sets a precedent that could unlock gigawatts of shuttered nuclear capacity across the country. At a time when NERC is warning that 13 of 23 assessment areas face elevated resource adequacy risks and plant closures could total over 105 GW in the next decade, every megawatt of reliable baseload generation counts.
Our take: The nuclear restart playbook is being written in real time at Palisades. Whether the economics and regulatory pathway hold up will determine whether other decommissioned plants follow suit. The industry is watching closely.

5. Portland General Electric Expands Into Washington with $1.9 Billion PacifiCorp Deal
What happened: Portland General Electric announced an agreement on February 17 to acquire PacifiCorp's Washington operations for $1.9 billion, gaining approximately 140,000 customers, three generation facilities (the 477 MW Chehalis gas plant, plus Goodnoe Hills and Marengo wind facilities), and 4,500 miles of transmission and distribution lines across 2,700 square miles. Manulife Investment Management is partnering with a 49% equity stake.
Why it matters: This is PGE's first expansion outside Oregon, signaling that regulated utility M&A is alive and well alongside the splashy independent power producer deals. Power sector M&A hit $142 billion in 2025, nearly double the prior year, and this deal suggests the momentum is continuing into 2026. The transaction still requires regulatory approval and could take about a year to close.
Our take: Watch for how PGE integrates PacifiCorp's Washington operations, especially on the wildfire mitigation front. Both utilities operate in high-risk fire territory, and the combined entity will need a unified approach.

6. Residential Electricity Prices Climb to 18.05 Cents per Kilowatt-Hour
What happened: The national average residential electricity rate reached 18.05 cents per kilowatt-hour in March 2026, up 5.4% year over year and 21% over the past five years. Regional variation is significant: New England averages about 30 cents/kWh while parts of the South and Mountain West remain closer to 12 to 14 cents.
Why it matters: Rising bills are the single most visible issue for utility customers and regulators. The drivers are compounding: natural gas price volatility, grid hardening investments, data center demand pulling on capacity markets, and weather-related costs from more frequent extreme events. Politically, this is fueling everything from the White House Ratepayer Protection Pledge to state-level pushback on utility capital spending plans.
Our take: The conversation about who pays for grid modernization and new load growth is only going to intensify. Utilities that can clearly communicate the value behind rate increases will be better positioned than those that cannot.

7. PG&E Plans to Underground Over 1,000 Miles of Power Lines by 2028
What happened: PG&E submitted its 2026 to 2028 Wildfire Mitigation Plan, which includes undergrounding 1,077 miles of power lines and hardening over 700 miles of overhead infrastructure. The plan also integrates drone-based asset inspections, AI-enhanced weather forecasting, and sensors that detect vibrations, sounds, and light anomalies on circuits that could indicate ignition risk.
Why it matters: Wildfire mitigation has become one of the biggest capital expenditure drivers for utilities in fire-prone regions. PG&E's approach reflects a bet that burying lines is more cost-effective in the long run than repeated rebuilds, liability exposure, and public safety power shutoffs. The utility reports that no major wildfires resulted from its equipment in 2023 or 2024, validating the investment so far.
Our take: Undergrounding at this scale is a massive undertaking, and the cost per mile will be a closely watched metric. Other Western utilities are evaluating similar programs, and PG&E's execution will inform those decisions.

8. Utilities Move AI Copilots from Pilot Programs into Daily Operations
What happened: Multiple utilities are expanding AI-assisted analytics and generative AI copilots beyond pilot programs into operational deployment. At the DTECH 2026 conference, Microsoft showcased partnerships with Hitachi Energy and ThinkLabs AI to build grid copilots that unify IT and OT data. NextEra Energy is leveraging Google's generative and agentic AI to shift from reactive to predictive field operations. Use cases span control room decision support, outage prediction, vegetation management, and customer service automation.
Why it matters: The utility industry has historically been cautious about adopting new technology, but the AI copilot trend is accelerating faster than expected. A key development in 2026 is the shift from standalone AI tools to agent-enabled workflows that support multi-step processes across planning, operations, and field execution. Human oversight frameworks are being formalized alongside the rollout.
Our take: The utilities that figure out the right balance of AI assistance and human oversight will gain a real operational edge. This is still early innings, but the pace of adoption suggests AI copilots will be standard utility infrastructure within a few years.
