Peak demand is observed when a high level of electric demand occurs in our area. Specifically, appliance use during the Peak is costly, and affects power costs which may eventually reach customer bills. HMLD's Shave the Peak program is intended to increase awareness to help reduce HMLD's electric use during these peaks which will help control cost, and keep rates affordable. HMLD issues Shave the Peak alerts to notify customers when a peak is expected, and requests customers to take steps whenever possible to conserve electric use during the anticated peak window.

HMLD's system has an annual peak occurring typically on a hot weekday afternoon from June to August between the hours of 2pm and 7pm, and a monthly peak.
