How Extreme Summer Temps Impact Reliability

As we move into the warmer months, I want to take a moment to talk with you about how extreme summer temperatures can affect our electric system — and what we at Powell Valley Electric Cooperative are doing to ensure you stay powered through the heat.

When the thermometer climbs, so does our collective use of electricity. Air conditioners run longer and more frequently to keep our homes and businesses cool, especially during peak times in the morning and early evening. This surge in energy use places additional strain on the electric grid.

At PVEC, we take our responsibility to you seriously. Our mission is to provide safe, reliable and affordable power to every member, no matter the weather. That’s why we prepare all year long — through equipment upgrades, system maintenance and emergency planning — to make sure your lights (and your air conditioning) stay on when you need them most.

We also work closely with the Tennessee Valley Authority to ensure our local distribution system is ready to handle increased demand. TVA is responsible for generating and supplying the power we distribute, and during extreme weather events, they might request cooperative members across the Valley to reduce electricity use in order to relieve stress on the regional grid. Should this occur, PVEC will provide timely updates and guidance if energy-saving actions are needed.

Every member plays a part in supporting the reliability of our electric system. By adopting a few simple habits, especially during the hottest parts of the day, you can help reduce stress on the grid while also saving energy — and money.

Here are some suggestions:

• Adjust your thermostat: Set it to the highest comfortable temperature, and raise it a few degrees when you’re away.
• Use major appliances during off peak hours such as late evenings or early mornings.
• Take advantage of ceiling fans, but remember to turn them off when no one is in the room.
• Block out the sun: Keep curtains or blinds closed during the hottest parts of the day.
• Cook efficiently: Use smaller appliances like air fryers or toaster ovens, which generate less heat and consume less power.

Together, we can keep the power flowing. Extreme summer heat brings real challenges, but with preparation and cooperation, we can meet them head-on. Your efforts to conserve energy— especially during peak demand times — not only help reduce the load on our system but also contribute to a more reliable, resilient electric grid for our entire community.

Thank you for being a valued member of PVEC. As always, we’re here for you, and we appreciate your partnership in keeping our community safe, cool and connected this summer.
