As the artificial intelligence boom fuels a significant increase in electricity demand, states are exploring divergent strategies to manage the potential impact on consumer utility bills.
New Jersey has enacted legislation requiring large data centers to bear a greater share of the costs associated with their substantial energy consumption. Under the law signed in July, the New Jersey Board of Public Utilities is tasked with establishing a distinct rate structure for these facilities. This approach aims to ensure that the expenses for new substations, transmission lines, or other grid upgrades primarily driven by data center needs are not passed on to other customers. The legislation also mandates that large data centers commit to paying for at least 85% of the electricity capacity they request for a decade, providing a financial cushion should their demand decrease. Furthermore, regulators are directed to encourage data centers to implement clean energy generation, energy storage solutions, enhance power efficiency, and reduce demand during emergencies.
A separate law in New Jersey requires data center operators to report their energy and water usage to the state twice annually. The administration asserts these reporting and local planning measures will offer officials a clearer understanding of data center demands and assist communities in assessing local impacts and negotiating with developers.
Indiana is pursuing a different path. Instead of implementing universal statewide regulations for large data centers, state regulators have approved an agreement negotiated by Indiana Michigan Power (I&M), consumer advocates, and technology companies. This agreement emerged in response to significant planned projects, such as Amazon Web Services' $11 billion data center campus near New Carlisle and Google's $2 billion project in Fort Wayne.
I&M stated that the 2025 agreement requires new large customers, including data centers, to make long-term financial commitments for the electricity service they request. The utility argues that these commitments will enable it to leverage the new demand to benefit existing customers. I&M has proposed a $59 million reduction in base rates for 2027, attributing this possibility to revenue from large customers. If approved, an Indiana household using 1,000 kilowatt-hours of electricity per month could see savings of approximately $100 annually, with potential rate freezes for three years.
Daniel Turner, executive director of the advocacy group Power The Future, suggested that Indiana's approach is preferable to New Jersey's more prescriptive framework, though he believes neither has sufficiently addressed the need for new power generation to accompany the AI buildout. Turner advocates for new power generation to be integrated into data center development from the outset to add capacity to the broader grid.
The Trump administration has promoted a national model through its Ratepayer Protection Pledge, signed by major technology companies. This initiative aims to secure commitments from companies to cover the costs of additional electricity generation required for AI data centers, rather than transferring these costs to consumers. The debate over data centers has implications extending beyond local utility costs, with arguments made about the United States' competitiveness in the global race to develop and control artificial intelligence.
