Green Charge caters to businesses in California and New York City that sometimes pay 40 percent or more of their monthly electric bill in demand charges based on their peak electricity use. The company’s GreenStation technology uses utility and weather data to predict peak use and store energy accordingly.
The company says some 7-Eleven stores have been using GreenStation for the past two years. One 7-Eleven GreenStation energy storage system in New York endured Hurricane Sandy and then went on to save the business 56 percent on its electricity bills during the 2013 summer heat wave, according to Green Charge Networks.
Other Green Charge Networks customers include commercial office buildings, community colleges and municipalities, adding up to 1 MW as listed on the DOE’s Global Energy Storage Database.
