Large Load Customer Treatment: Recent State Action on Load Growth, Data Centers, and Generation Capacity

DSIRE Insight's blog post tracks large-load customer policy actions across 33 states in the first half of 2025, covering interconnection rules, utility tariffs, and legislative studies tied to rising data center demand. The team logged over 85 discrete actions, including new large-load tariffs proposed or approved in Nevada, Utah, Indiana, Wisconsin, and Missouri. It also points to two companion trackers: the Database of Emerging Large-Load Tariffs (DELTa) and the 50 States of Power Decarbonization Report.
