Norwich — As oppressive heat and humidity is expected to continue this week, Norwich Public Utilities is encouraging customers to be prudent when using electricity to stay comfortable.

While not declaring a power alert, NPU expects demand for electricity to be very high through the middle of the week with temperatures likely to exceed 90 degrees with increasing humidity. NPU hopes to decrease the impact on its electrical infrastructure while the high temperatures persist.

“It is important that all of our customers to use electricity wisely while keeping cool in the days ahead,” NPU General Manager Chris LaRose said in a news release. “It is also very important for everyone to keep an eye out for those who may have a tough time in extreme weather, particularly the elderly or infirm, to make sure everyone stays safe during this challenging stretch of weather.”

Because a portion of NPU’s annual costs for electricity are based on peak demand days, by using energy efficiently customers can help keep their overall electric costs lower throughout the year. NPU is requesting that customers take the following simple steps to conserve electricity that will have little or no impact on their comfort.

Only use window air conditioning units when someone is home and set central air system to 73 degrees or higher.

Wait until after 7 p.m. to use major appliances, such as dishwashers or clothes dryers. Minimize the use of appliances that generate heat before 7 p.m., including computers, curling irons, hair dryers, stereos and TVs, which can add to the heat inside a home. Avoid using the oven to cook. Use stovetop, microwave or grill outside.

Install energy efficient lighting. Only about 10-15% of the electricity that incandescent lights use results in light, the rest is turned to heat.  Install window coverings to minimize heat coming into a home or business.
