Peak Energy

Peak Energy Events: What Do They Mean?

You may have heard or seen a Peak Energy Event message from DTE Energy. It means that the current demand for energy is high, potentially jeopardizing energy delivery. And if we work together to reduce our energy use during these times, our efforts can go a long way.

Extreme Temperatures = High Energy Demand

When an excessive demand for energy occurs — usually due to extreme temperatures — it can affect energy delivery for everyone in our area. We’re committed to doing our part to ensure that the energy grid operates efficiently and reliably. When we voluntarily reduce our consumption during Peak Energy Events, we’re helping.

We understand more than anyone the role that energy plays in our daily lives — that’s why our biggest priority will always be to provide safe, reliable and affordable energy, giving our customers peace of mind.

We know that seasonal temperatures can be volatile, and it’s the reason we plan for peak demand periods throughout the year by making certain our power plants and substations are in top operating condition. However, when the entire energy grid becomes strained, Peak Energy Events may be necessary even after we have taken several precautionary measures including:

  • Our internal energy reduction process has been instituted across all of the DTE Energy properties

  • Service has been interrupted for commercial and industrial customers on interruptible rates and intermittently interrupted for residential customers enrolled in our CoolCurrents® Program

Simple Steps

Your small changes can make a big difference. Here are just a few things you can do during a Peak Energy Event:

  • Adjust your thermostat by at least two degrees

  • Refrain from using appliances that require more energy until after 9 p.m. (i.e., dishwasher, washing machine, clothes dryer)

  • In the summer, avoid heating up your kitchen and grill outdoors or use your microwave

  • During the winter, open blinds and curtains on south-facing windows to capture sunlight
Even with these minimal efforts, we can be impactful in reducing energy. Learn about more ways to save energy and keep your home comfortable.
