The Public Utilities Commission (PUC) has approved Dead River Company to sell off-peak electricity for use only in electric thermal storage (ETS) units. As a result, the company also is partnering with Biddeford-based Thermal Energy Storage of Maine (TESM), the manufacturer’s representative of Steffes ETS systems, to sell and install the units as well.
“We want to be the source for all our customers’ energy needs,” said Bob Moore, the CEO of Dead River Company. “Bringing as many options as possible under one roof is another facet of our customer service. In TESM, we’ve found a partner with deep knowledge and understanding of ETS.”
Electric Thermal Storage converts off-peak, low-cost electricity to heat and stores it in high-density ceramic bricks for use 24-hours a day. ETS units can be used either to supplement another heat source or as the sole heat source in a home or business.
The technology was first introduced in Europe in the aftermath of World War II, when frequent power outages created uncertainty in the energy supply. ETS technology was developed in order to store heat for later use.
In North America, ETS is currently used in 24 states and four Canadian provinces. Steffes Corporation has been manufacturing ETS systems in North America for more than 25 years.
