Peak shifting on Xcel
Xcel’s on-peak price is about 2.7 times off-peak, from 5 to 9 pm on non-holiday weekdays. A battery that charges from midday solar and covers that window is the core financial case for storage in Xcel neighborhoods.
United Power members
United Power sets its own rates and export terms. Whether a battery pays depends on whether your rate has a time-of-use or demand component. We check your current tariff first.
Permit details and incentives
Broomfield’s solar permit site plan must show the battery’s location, so storage is best designed in from the start. Switch Together Broomfield includes optional battery storage if you’re comparing offers. As of September 2026, Colorado’s 10% battery income-tax credit applies through tax year 2026, and batteries are exempt from state sales tax; verify current terms.
