What happens to other ratepayers if a data center leaves early?

A utility may build power plants or transmission lines for a very large customer such as a data center. Those costs are recovered over many years through rates. If the customer leaves early, the unrecovered cost can fall on everyone else the utility serves.

To limit that risk, regulators in some states have approved or considered rules for large customers: a long minimum contract term, a minimum monthly bill whether or not the customer uses the power, an exit fee, or collateral such as a letter of credit. The terms differ widely from state to state and from utility to utility.

For a lender, the same terms matter in a different way. A long power contract with a minimum bill supports the data center's ability to repay, and a short one does not.

What to check

• The contract length, and the minimum bill the customer must pay.
• The exit fee, and what collateral the utility holds.
• The regulator's docket that approved the terms.
