Energy Curtailment - Utilities

MidAmerican Energy Curtailment Program

Curtailment Season – June 1 to September 30

What is curtailment?

The Energy Curtailment program is a way you can help the university save money during the hot summer months. MidAmerican Energy provides a reasonable financial incentive for the university to participate in this program. Between June 1 and September 30, you may be asked to reduce your electrical usage during peak-demand times. Curtailment strategies to reduce this electrical usage in GEF buildings are listed on the Buildings & Curtailment page.

When does the UI curtail?

To accomplish our goal we will be asked to curtail the use of electricity for up to six hours at a time to help MidAmerican Energy manage the peak electrical load on very hot summer days. Generally, the conditions for curtailment are extremely hot weather, usually 90° or higher and humidity in the 80% range. Historically curtailment begins about 1 or 2 p.m. with building controls initiated 30 minutes prior.

The agreement allows that we may be called to curtail up to 16 times between June 1 and September 30.  The university will experience at least one curtailment event annually.

How will I know if there is a curtailment?

When curtailed, MidAmerican Energy will give the university as much notice as possible, but this may be as little as two hours notice. Building Coordinators and occupants of General Fund buildings will be notified via email. There will also be an alert on the Facilities Management home page.

Does my building curtail?
