Utilities and companies: data centers must fund grid upgrades and should not raise household rates

Panelists from utilities and industry said data‑center electricity demand varies from small customers (about 0.5 MW) to very large loads that can be hundreds of megawatts, and that the process for adding large loads is rigorous and regulated.

Austin Allen, director of data center development for Black Hills Energy, explained the utility uses its Large Power Contract Service (LPCS) tariff to protect retail customers and to require data‑center customers to pay costs they impose on transmission or generation systems. "Our LPCS tariff requires that new data center customers pay for any costs that they cause to the system," he said.

Jonathan Noble (Microsoft) emphasized multi‑tier oversight (utility, state public‑service regulators and federal reliability standards) and said Microsoft’s commitments include infrastructure investments to avoid shifting costs to other ratepayers. Noble noted industry‑wide capacity needs and cited a market estimate of an 11‑gigawatt shortfall in 2025 used to illustrate national demand; panelists said that increased demand also creates opportunities to invest in generation and transmission capacity locally.

Panelists said utilities run interconnection studies, model the need for new generation or transmission, and require customers to fund incremental resources where necessary. Black Hills and BOPU representatives said Cheyenne’s system is highly reliable and that properly structured contracts and state statutes codifying cost‑allocation protect retail consumers from rate impacts.
