HOLYOKE, Mass. (AP) -For the second day in a row, the operator of the region’s power grid on Sunday declared a power watch for the state of Maine.

ISO New England said Sunday that system conditions in Maine resulted in a capacity deficiency, creating a need for Mainers to conserve electricity through Sunday night.

Consumers were being asked to reduce their electricity use by shutting off unnecessary lights and electrical appliances and putting off activities such as laundry and dishwashing.
