ST. LOUIS, Mo. (First Alert 4) – Ameren is asking customers to limit energy use after reports of high usage due to incoming weather conditions.
In a release on Saturday, Ameren stated that the Midcontinent Independent System Operator (MISO), the regional grid operator, told energy companies across the Midwest to tell customers to conserve electricity until further notice due to high demand and weather conditions.
Ameren said they currently have enough energy available to cover needs, but that reducing use now will ensure customers in Missouri, Illinois and across the Midwest are safe in the cold weather.
In the release, Ameren offered these methods to conserve electricity:
Lower your thermostat. Wear additional layers of clothing, and set the thermostat as low as is comfortable. Make additional adjustments when leaving the house.Cover drafty windows and weatherize when possible. Block cold air from coming in by stuffing towels along windows or underneath doors. Sealing cracks and openings reduces drafts and cold spots, also improving comfort.Unplug or turn off nonessential appliances. Unplugging devices when they’re not in use reduces energy consumption and lowers utility bills.Reduce the temperature setting on electric water heaters. Lowering the water temperature saves money and reduces the risk of scalding.
Ameren also said it is taking steps to reduce energy consumption. These steps include activating available demand response programs among customers who have previously entered into an agreement with the company to reduce energy consumption during times of high demand.
MISO is responsible for monitoring the portion of the electric grid it oversees and providing instructions to its members; this includes Ameren and its customers. MISO comprises a pool of electricity generators and users that stretches from Canada to the Gulf of Mexico, which informs when actions are needed to reliably maintain a section of the grid.
