WORCESTER, Mass. -- The high temperatures are expected throughout the week and National Grid is expecting higher demand.

The utility company is asking its customers to limit their energy use between the peak hours of 2 p.m. to 7 p.m.

They recommend people reduce the use of window or room air conditioners and large electric appliances, like ovens and clothes dryers during these times.

“By making these small temporary changes to energy use during these hottest days of the year, we’re seeing this week, you can help reduce air pollution, and you also lower stress on the electric grid which benefits the whole community, so that’s why we’re asking people to make these changes just for a short amount of time during these hot days,” Christine Milligan, National Grid spokesperson said

National Grid is also reminding people to check on their elderly neighbors, especially those who don’t have an air conditioner.

It’s because prolonged temperatures of 90 degrees or higher can lead to heat-related illness.
