Central Maine Power connected a generator to a power substation in York County last week as part of an effort to prevent service disruptions in the area with more extreme heat expected. “We were concerned that had we not brought in this additional generator that there could be some disruption to service which is why we were on top of it and planning for it ahead of time,” said Emily Downing of CMP. The move comes in response to increased strain on the grid from customers using air conditioning systems to stay cool. CMP says the Lebanon substation is the only location where they expect a generator will be used. The company expects the generator to remain on site through August. “Here in Lebanon, had we not brought a generator in, there may have been some interruptions to service and we’re not going to let that happen,” Downing said. The substation serves an estimated 3,500 households. CMP is also sharing advice on how to conserve energy and save money on your utility bill. The company recommends setting thermostats at 78 degrees to save up to 10% on cooling costs, using drapes and curtains to reduce solar heat buildup and being mindful of the spaces you’re cooling. “Try to only cool the rooms you are using so if you have a spare bedroom if you’ve got that office that isn’t in use or any area of the house that just doesn’t see that much foot traffic go ahead and shut those doors,” Downing said. ISO New England, the group that oversees the power grid across the region, issued a “precautionary operational alert” due to the weather Monday.ISO New England expected there could be tight operating conditions during the afternoon and evening but added there was no request for conservation.
