Relating to: large energy customer fees; electric utility very large customer class; a renewable resource tariff; building requirements for data centers; water usage by large customers; required pay rate on large-scale data center projects; and granting rule-making authority. (FE)
SB 729 imposes annual fees on large energy customers (primarily large data centers) based on their peak electricity demand: $2 million for 100-250 MW, $3 million for 250-500 MW, and $1 million more for each additional 250 MW. Fifty percent of these fees fund the Green Innovation Fund via the Wisconsin Economic Development Corporation. The bill also requires data centers to report actual water usage annually and certify compliance with sustainable building standards (like LEED or BREEAM) within three years of operation. It defines "large-scale data centers" as projects costing $250 million+ in construction or equipment over 60 months.
