(LOUISVILLE, Ky.) With the continued high temperatures today, the Midwest Independent Transmission System Operator has once again requested all utilities in the Midwest to ask their customers to voluntarily conserve energy due to strain on the regional grid. Electricity supplies in Kentucky remain adequate at this time, but concerns about capacity in the region have prompted this request.

Customers can follow the tips below to help reduce demand.

• Close your draperies or blinds during the day to keep out sun and heat, particularly on the southern exposure side of the building. If outside temperatures fall to a comfortable level at night, open drapes and windows.



• Set your thermostat to 78°. The energy savings can be significant — as much as five to eight percent of your air conditioning costs for each one degree that you raise the thermostat.



• Turn off lights and appliances when they're not in use. Besides wasting electricity, they generate heat.



• Cook and use the clothes dryer early in the day, when temperatures are usually cooler.



• Use the microwave more because it's less likely to heat up the whole room.



• Use desk or ceiling fans. They won't lower the temperature, but they will cool your skin and make you more comfortable. A light breeze will make you feel about 7 degrees cooler.
