Your energy costs are based on how much electricity you use and when you use it. Energy use aligns with two seasonal periods and the winter season now includes the month of May.

Winter: November 1 to May 31 (previously November 1 to April 30)

Summer: June 1 to October 31 (previously May 1 to October 31)

The year-round On-peak period, when electricity is needed the most and you pay the highest price, is 4 p.m. – 9 p.m. Shifting energy use to Off-peak or Super off-peak hours can help you save energy and money. Review your pricing plan at to understand how these changes might impact your business.
