AP: six states fight utility rate hikes

Arizona Attorney General Kris Mayes is fighting Arizona Public Service and other monopoly utilities over rate cases as officials in at least six states challenge who should pay for power-system upgrades tied to AI and data-center growth. New York Governor Kathy Hochul, Maryland lawmakers, New Jersey legislators, Indiana consumer advocates and Pennsylvania regulators are all pursuing versions of the same argument: ordinary households should not absorb costs created by very large new electricity users. The disputes are unfolding as utilities seek higher returns and more spending on transmission, substations and generation to serve projected demand growth. The Associated Press reported the fights now span at least Arizona, Indiana, Maryland, New Jersey, New York and Pennsylvania. ### Why are state officials tying higher electric bills to AI and data centers? The Associated Press reported on May 17 that officials and lawmakers in at least six states are pushing back on utility rate increases they say are linked to the electricity needs of data centers and artificial intelligence computing. Those projects can require dedicated substations, transmission upgrades and new generation, and critics say utilities earn more when regulators approve bigger capital plans and higher customer rates. (fox59.com) A January 2026 PowerLines report, cited by E&E News and Fortune coverage indexed in search results, said electric and gas utilities sought nearly $31 billion in rate increases in 2025, more than double 2024 levels. That broader wave of rate cases has given state officials a new opening to scrutinize whether large-load customers are paying enough of the costs they impose on the grid. (fox59.com) ### Which states have moved from complaints to concrete policy steps? New York moved on February 12, when Hochul announced a Public Service Commission proceeding under her Energize NY plan to ensure data centers “pay their fair share” for grid upgrades. Her office said the proceeding is aimed at protecting ratepayers while modernizing how large energy users connect to the grid. (eenews.net) Maryland’s General Assembly passed House Bill 1082 in 2026 to apply large-load rate schedule requirements to certain data centers, according to the bill text. Separate Maryland consumer communications this year have also warned residents about how data-center demand could affect utility bills. New Jersey lawmakers advanced legislation in January that would require electric companies to develop new tariffs for “large-load” data centers. (governor.ny.gov) The New Jersey Monitor said the bill’s stated goal is to protect residents, businesses and other regular ratepayers from increased costs driven by power-hungry centers.

Pennsylvania’s PPL Electric filed a settlement on March 13 that would create a new rate class for large data centers and require those customers to make 10-year commitments, pay for infrastructure upgrades and face penalties if they leave early. WHYY reported the deal would also have data centers provide $11 million for low-income rate relief, while Utility Dive said the filing would raise PPL’s annual base distribution revenue by about $275 million. (newjerseymonitor.com) Indiana regulators approved large-load interconnection rules in February 2025, and a separate settlement involving Indiana Michigan Power, Amazon Web Services, Microsoft, Google and the Data Center Coalition required annual support for low-income customers. Indiana Capital Chronicle reported the three data-center signatories agreed to provide $500,000 each year for five years to the Indiana Community Action Association. (whyy.org) ### What is the argument from consumer advocates and elected officials? Kris Mayes told the AP she saw a need to stand up against what she called “the blatant corporate greed of our monopoly utilities” in Arizona. Consumer advocates in several states are making a narrower regulatory claim: if a utility builds infrastructure mainly for very large new customers, those customers should bear more of the cost through special tariffs, upfront payments or long-term contractual commitments. (utilitydive.com) Pennsylvania lawmakers have also begun writing that view into legislation. The Pennsylvania House said a bill advanced by state Rep. Robert Matzie would require data centers to contribute to universal service programs and supplement low-income energy assistance. ### What happens next in these fights? The Pennsylvania Public Utility Commission is still weighing the PPL settlement filed March 13, including the proposed large-load rate class and low-income relief terms. (fox59.com) New York’s Public Service Commission proceeding opened in February and will determine how the state assigns grid-upgrade costs to data centers. Maryland utilities must submit rate schedules for covered large-load customers under House Bill 1082, while New Jersey’s proposal still needs action by the full legislature and regulators.
