Duke Energy's Summer Heat Wave Response

As temperatures soared to unprecedented levels across North Carolina and South Carolina during the first heat wave of summer 2025, Duke Energy is extending its heartfelt appreciation to customers for their robust support in managing energy usage. The company's customers have been instrumental in curbing electricity demand during peak hours, thus contributing to a more stable power grid.

In a recent statement, Ben Harrison, the Vice President of Grid Operations at Duke Energy, acknowledged the inconvenience faced by customers but highlighted the significant impact of their energy-saving efforts. "We appreciate our customers' support this week to reduce their electricity usage during the hottest parts of the day. Those actions made a significant difference for all," Harrison said, underscoring the importance of community collaboration during challenging weather conditions.

Record Energy Usage and Demand Management

This past week, Duke Energy recorded an unprecedented demand for electricity, reaching a high of 35,269 megawatt-hours on June 24, 2025. This figure surpassed the previous summertime record of 34,439 megawatt-hours established in July 2024. The energy consumption peak reflects an increased reliance on various energy sources, including nuclear, natural gas, hydropower, renewables, and coal, as temperatures continue to climb. Duke Energy has indicated that its all-time peak electricity usage, which stood at 37,260 megawatt-hours earlier this year, highlights the growing energy needs across both states.

The company's diverse energy mix is vital for meeting demand, particularly in a season characterized by soaring temperatures. Duke Energy is committed to expanding its capabilities with upcoming solar and energy storage initiatives and plans to enhance its natural gas plants over the next five years, highlighting its focus on economic development and sustainability.

Energy Efficiency Tips for Customers

In the face of persistent heat, Duke Energy advocates for year-round energy efficiency practices to help customers save on their electric bills. The utility has compiled several tips to assist customers in managing their energy use effectively during the summer months:

1. Adjust Your Thermostat: Setting your thermostat a few degrees higher can significantly cut energy costs. Consider this approach particularly during peak temperatures when systems must work harder to maintain indoor comfort.

2. Modify Laundry Settings: Using cooler water for laundry—switching from hot to warm—can halve the energy used per load, providing a straightforward method for conservation.

3. Timing is Key: Reducing the use of heat-generating appliances during the hottest parts of the day can also contribute to overall energy savings.

4. Utilize Natural Shade: Close curtains or blinds on sunny sides of the home to minimize heat absorption, aiding in keeping indoor areas cooler.

5. Optimize Ceiling Fans: Running fans clockwise can push cooler air down into living spaces, enhancing comfort without additional air conditioning.

During the hot weather period from June 23-24, over 521,000 customers participated in Duke Energy's demand response programs, demonstrating the power of collective action in managing peak energy use. Duke Energy's customer demand response initiatives help to alleviate pressure on the electric grid during high-demand phases.
