If you use a central air conditioner or air source heat pump, then you're eligible for CoolCurrents® our interruptible space conditioning rate designed to help reduce your cooling costs and, for air source heat pump participants, the heating costs on your energy bill while keeping you feeling comfortable.
Here's how it works
Getting started is easy. First, you'll need to hire an electrician to wire your central air conditioner or air source heat pump for a separate smart meter. See the CoolCurrents FAQs for details. Next, call us at 800.477.4747 to schedule installation of a smart meter and a small device to control your air conditioning.
On select summer days, DTE will briefly interrupt your air conditioning or heat pump in 15-minute intervals by sending a signal to the device. Your air conditioning or heat pump cycling will be limited to no more than eight hours in a 24-hour period and no more than 30 minutes per hour. You'll know that your service has been interrupted when the red light on your device is lit.
CoolCurrents has a monthly service charge of $1.95 from June through October (regardless of usage). However, this special rate program can help participating customers save up to 17% on their cooling costs. Additionally, customers who use a whole home air source heat pump can save up to 35% in the heating months.
Air Source Heat Pumps
Air source heat pumps qualify for the D1.1 CoolCurrents® rate, helping you to save even more. They use electricity to transfer energy between indoor and outdoor air. Because they move heat rather than generate heat, these systems consume far less electricity than electric furnaces, baseboard heaters or space heaters.
DTE Energy does not sell or install air source heat pump systems. Visit our Energy Efficiency Directory to find a contractor near you. Select "Heat Pump Replacement" to find contractors that sell and install air source heat pumps.
