The city of Evanston, Illinois, selected Verde Energy USA, an independent retail power supplier and energy solutions provider, as the city’s electricity supplier, effective August 2013.
As part of its agreement with the city, Verde Energy will also install Ice Bear technology — a clean energy storage system — in one of Evanston’s municipal buildings.
Verde, which serves over 70,000 customers in 14 municipalities through aggregation programs, participated in the city’s open request for proposal process to select an electricity supplier for the city’s ongoing electricity aggregation program.
The city received multiple bids, and the Verde proposal offered the lowest price. Under the terms of the agreement with Verde, residents will receive a 100 percent renewable fixed rate of $0.05192/kWh through August 2014. Residential and small commercial retail customers will have the right to “opt-out” of the aggregation program without penalty or a cancellation fee.
The Ice Bear unit replaces conventional air conditioning condensing units, a component of a typical building cooling system. It shifts air conditioning electrical power demand to off-peak hours by using plain water to make ice at night, when the electric grid is generally unstressed.
Then, during a hot summer day, when demand goes up and electric prices may be higher, the melting ice bathes the air conditioner’s compressor with cool air so the air conditioning unit uses less energy at a peak demand time to cool the building. The melted water is then recycled through the system and the process begins again the following night. The result is lower energy costs and increased grid reliability.
As part of Verde’s pioneering Energy Storage Solutions Program, Evanston will join the Illinois cities of St. Charles and Naperville in their leadership efforts to advance innovative thermal energy storage technology within Illinois.
