About This Toolkit
Published: April 9, 2026
As data centers spread across the country, they are imposing striking costs on utilities, ratepayers, water authorities, and communities. State governments are looking for new tools to contain the impacts of massive data center spread, including on public health and the climate. This toolkit draws from many examples in 2025 state legislative sessions, during which the Climate XChange team reviewed over 140 bills addressing data centers across 34 states, as well as emerging examples from 2026.
This resource represents one of five installments in Climate XChange’s State Policy Toolkits for Data Center Regulation, which will be released throughout 2026. This document tackles the tools that states can use to address and mitigate the impacts that data centers have on electricity affordability and reliability. It should be considered alongside other toolkits describing state policies addressing data center impacts on water resources, greenhouse gas emissions, tax and employment justice, and transparency concerns. Look out for the complete Toolkit Series at Climate XChange’s Resources for Regulating Data Centers Page.
The Issue
Data centers are the leading driver of electric load growth in the United States, and they have the potential to impact the affordability and reliability of the electric grid in several key ways. As electricity demand grows, grid operators will call on more expensive generation sources to help meet peak demand, and utilities will also have to invest in upgrades to the transmission and distribution systems. The cost of these upgrades would traditionally be shared among all ratepayers. At the same time, energy supply shortfalls associated with data centers have been predicted for several parts of the country. Data centers reacting in similar ways to small faults on the grid could also create grid imbalances that require operators to take action, lest a wide blackout be triggered.
The Toolkit
State policymakers have unique jurisdiction over the retail electric system, and therefore have a wide range of tools at their disposal to help combat these risks. On the affordability side, these tools include large load tariffs, which can shield ratepayers from rising electricity costs and the risk of stranded assets, as well as better contracting review processes at Public Utility Commissions, and data centers bringing their own clean power to the grid. On the reliability side, states can also incentivize or mandate flexibility requirements for data center load, as well as put transparency requirements in place to help grid operators plan for load growth.

Note: With the rapid buildout of data centers across the country, states must have strong policies to prevent their negative impacts on the environment, climate, energy systems, and local communities. Climate XChange’s policy toolkits, educational programming, and technical assistance are solely focused on addressing these impacts. Our organization is not involved in advocacy, nor does it have the expertise to assess the broader societal and economic effects of widespread artificial intelligence adoption in the United States.
