UI Announces Energy-saving Curtailment Today

The University of Iowa has announced an energy curtailment today, beginning at 1 p.m. and ending at 7 p.m. The curtailment, called for by MidAmerican Energy Corporation, will affect most buildings on the main campus. The Oakdale Campus is not affected.

The UI generates some electrical energy at its own power plant and has a contract with MidAmerican to provide additional electricity to the campus. Part of this contract includes participation in MidAmerican's electrical curtailment program, which limits electrical usage during peak periods. Curtailment -- meaning reduction of electrical power for up to six hours -- can be requested by MidAmerican between June 1 and Sept. 30. The program benefits the university through lower utility costs. Curtailments have previously occurred during the extremely hot afternoons and early evenings of summer.

A number of strategies will be used to reduce power use in most buildings on campus, UI officials say, including increasing air temperatures, cycling air conditioning systems on and off or even turning them off completely during the curtailment, shutting down ventilation systems, and/or turning off non-essential lighting. In the few buildings where these strategies will not work, either because of their special occupancy needs or for technical reasons, departments will be asked to voluntarily reduce energy use.
