Colorado Utilities Are Asking Customers to Cut Power Use — Here's Why

What happened

On July 24 and 25, 2026, Colorado Springs Utilities (CSU) asked its customers to voluntarily conserve electricity as a regional heat wave strained the grid. CSU's guidance was specific: turn the thermostat up rather than run the AC harder, open windows to cool the house naturally where possible, and avoid running washers, dryers, and dishwashers during the hottest part of the day.

The appeal wasn't limited to Colorado Springs. The Southwest Power Pool (SPP) — the grid operator covering large parts of the western and central U.S., including Colorado — issued an Energy Emergency Alert Level 2 for its West Balancing Authority Area effective July 24, 2026. High demand across Arizona, Colorado, Montana, Nebraska, South Dakota, Utah, and Wyoming pushed electricity consumption up while reducing the grid's operating flexibility. SPP said the voluntary conservation response was enough to stabilize the system without resorting to mandatory rotating outages.

The bigger picture: a national grid emergency

Colorado's conservation appeal was part of a much larger story. A heat wave stretching across the country in late July 2026 put roughly 160 million people in 30 states under extreme-heat alerts, and the U.S. Department of Energy issued emergency orders to help grid operators keep the lights on as demand approached record levels in several regions. News coverage described the national grid as “stretched to the limit” by the combination of extreme heat and record electricity demand.

Why this keeps happening

Air conditioning is the single biggest driver of summer peak demand, and it all lands in the same few-hour window — roughly 2pm to 8pm, when it's hottest outside and everyone's AC is running at once. Grid operators size their systems for the worst realistic day, but as heat waves get more frequent and intense, and as new demand (including data centers) grows faster than new generation and transmission capacity, those worst-case days are showing up more often. Colorado is also dealing with rising utility costs tied to wildfire mitigation and grid-hardening spending, on top of the demand growth — a combination that shows up in both your bill and, on the worst days, in your utility's inbox asking you to use less power.

How to reduce your exposure

You can't control the regional grid, but you can control how much of your own afternoon demand depends on it. Two things help most:

1. 1
   Shift what you can off peak hours: Run the dishwasher, laundry, and EV charging in the morning or overnight instead of the 2pm–8pm window utilities are watching most closely.
2. 2
   Generate some of your own power during exactly those hours: Colorado now allows permit-free plug-in solar up to 1920W under HB 26-1007. A panel on a south-facing balcony or wall produces the most electricity in the early-to-mid afternoon — the same hours grid operators are asking everyone to cut back.

Colorado's law takes effect October 1, 2026 — you can research and plan a system now so you're ready when it does.

Bottom line

Conservation appeals like CSU's aren't a one-off — they're what happens when hotter summers meet a grid that's growing demand faster than it's growing supply. Trimming your own peak-hour draw, including generating some of your own power during the exact hours the grid is stressed, is the most direct way to stop being part of the problem the next time this happens.
