FAIR LAWN, N.J. — CALMAC®, a leading supplier of energy storage systems, applauded the Massachusetts legislature on the passing of energy bill H.4568. The bill promotes renewable energy, requiring the state to seek long-term contracts for 1,600 MW of offshore wind power and 1,200 MW of hydropower. It also includes provisions to facilitate the adoption of energy storage by empowering the Department of Energy Resources to create procurement targets and incentives for utilities, households, and businesses.

H.4568 uses a broad definition of energy storage that includes distributed thermal energy storage technologies, such as CALMAC’s IceBank® system for behind the meter applications. CALMAC said its solution serves as a “battery” for a commercial building’s air conditioning system. The IceBank system creates and stores ice at night. The next day the ice is used by the air conditioning system to keep occupants comfortable during peak demand hours, when the grid is nearing full capacity. The ability to reduce energy consumption during peak hours can be particularly beneficial for commercial buildings across the state, specifically in Boston, which endures a peak demand charge of $45 per kW. As a result of Massachusetts peak demand charge, electricity costs nearly 80 percent more during the day than at night.
