Dominion Energy South Carolina filed a 12.73% rate increase request on January 2, 2026, and a near-unanimous comprehensive settlement was submitted to the PSC on May 8, 2026, reducing the revenue ask from $322M to $207M with a 7.62% residential bill increase (~$12/month) effective July 1. The Commission's statutory order deadline under S.C.
APS's evidentiary hearing before the Arizona Corporation Commission began May 18, 2026, and is running through late July with more than 30 intervenors; APS seeks a ~14% base rate increase and proposes a controversial Formula Rate Adjustment Mechanism (FRAM) that would allow annual rate increases without a full rate case. The case is a national flashpoint for data center cost allocation—APS proposes a 45%+ rate hike for data center customers—and for utility formula ratemaking reform, with Attorney General Kris Mayes intervening and calling the request 'naked corporate greed.' GR professionals should track both the FRAM disposition and the data center rate class outcome, as the ACC's all-elected commission faces a contested July primary for two open seats that could shape the final vote.
TEP's evidentiary hearing began April 22, 2026, seeking a ~14% rate increase affecting more than 400,000 customers; closing arguments are due in July 2026, with TEP requesting new rates effective September 2026. Commissioners challenged TEP during hearings over whether residential customers were subsidizing infrastructure costs tied to Project Blue, a large Pima County data center—making this a leading test case for data center cost-shifting at a state commission.
The Pennsylvania PUC voted 5-0 on June 4, 2026 to approve a modified settlement reducing PPL's original $356M request to $275M (a 4.9% residential increase, ~$184/month), with new rates taking effect July 1, 2026. Critically, the settlement creates Pennsylvania's first dedicated large-load tariff for data centers—requiring long-term service commitments, minimum demand guarantees, and financial protections to prevent cost-shifting to residential customers—establishing a model the PA PUC directed other EDCs to adopt.
Xcel Energy filed for a $356M annual electric revenue increase (9.9%, ~$9.94/month for residential customers) on November 21, 2025; a non-unanimous partial settlement reducing the request to $225M was submitted, but is opposed by AARP, the Colorado Office of Utility Consumer Advocate, and the City of Boulder, with a final PUC decision expected in Q3 2026 and rates targeted for August 2026. The proceeding runs simultaneously with Xcel's parallel gas rate case (Proceeding 25AL-0499G, hearings July 23–31), representing the largest back-to-back regulated revenue ask in Xcel Colorado's recent history and placing dual-fuel affordability pressure on Colorado ratepayers.
Under Illinois' Climate and Equitable Jobs Act (CEJA), ComEd's annual capital expenditure reconciliation and updated multi-year grid plan is before the ICC with evidentiary hearings set for August 11–12, 2026, and a proposed order due around October 14, 2026; the 2026 cycle is especially high-stakes as ComEd's all-in rate hit a 10-year high of 17.07¢/kWh driven by record PJM capacity auction prices ($333.44/MW-day). The ICC cut $25.4M from ComEd's $268.5M December 2025 reconciliation request and is expected to apply aggressive prudency scrutiny again, with staff and intervenor direct testimony due May 14 and rebuttal exchange running through late July.
DTE Electric filed an application on March 18, 2026, seeking expedited MPSC approval of a Large Load Provision applying to incremental loads exceeding 100 MW at a single site or in aggregate—directly tied to the controversial December 2025 ex parte approval of a 1.4 GW special contract with a hyperscale data center (Oracle/OpenAI) in Saline Township. The Michigan Attorney General and consumer advocates have challenged the adequacy of ratepayer protections, and the MPSC has reserved authority to reopen the underlying special contract (Case No.
On May 28, 2026, the Georgia PSC approved a $285M annual fuel cost savings settlement for Georgia Power customers, but simultaneously opened a new, standalone investigation into how Georgia Power's largest Real-Time Pricing (RTP) customers—primarily data centers—contribute to rising per-unit fuel costs, after PSC staff found large industrial customers drive up average fuel costs for all customers by approximately 5–11% per month. The commission committed to completing this investigation before end of 2026, with the outcome directly informing cost allocation methodology in Georgia Power's next base rate case (rates frozen through 2028 under the July 2025 IRP order).
