"Under President Trump’s leadership, the Department of Energy will use all tools available to maintain a reliable, affordable, and secure energy system for the American people. This order ensures Duke Energy Carolinas can supply its customers with consistent and reliable power throughout peak summer demand."
The emergency order remains in effect through Wednesday.
Power companies across the East Coast are urging customers to conserve energy as the temperatures soar and say they’re ready to respond if outages arise.
Con Edison said crews have been working around the clock in hot conditions to restore power to customers in the Bronx who were affected by the extreme weather conditions.
"The heat, humidity and customers’ need to run their air conditioners to stay comfortable place stress on electric delivery equipment," the company said. "Con Edison has asked customers to use energy wisely during the heat. That helps customers save money and helps Con Edison keep service reliable."
The company asked customers to refrain from using appliances like washers, dryers and microwaves.
Eversource has also asked its customers in Massachusetts, Connecticut and New Hampshire to be aware of their energy usage.
"While high electricity usage during a heat wave can put a strain on the electric system, the energy company is prepared to meet the increased demand, and its crews are ready to respond to any outages or issues that may arise," the company said.
The company said that during the summer months, customers in Connecticut use about 35% more energy to keep cool, and that can be even higher when the state sees multiple heat waves like what has occurred in years past.
The company said Massachusetts uses about 30% more energy, while New Hampshire sees about 20% more demand.
