Colorado's largest power supplier is going to charge more this summer for customers who use the most electricity.
XCel Energy won approval from state utility regulators Wednesday to institute tiered electric rates in summertime. That means that residential customers will pay higher rates for each kilowatt hour once they exceed a monthly threshold.
XCel's plan would give the utility's 1.1 million Colorado customers a lower rate for the first 500 kilowatt-hours per month and a higher rate for all electricity above that amount.
Regulators say the typical residential customer uses about 687 kilowatt-hours a month during the summer.
