Texas School District Lowers Peak Demand Using Ice-Based Energy Storage
IceBank tanks allow district to reduce peak energy consumption by more than 20 percent
FAIR LAWN, N.J. — CALMAC® announced that the Alamo Heights Independent School District (AHISD) in San Antonio is using the company’s ice-based energy storage technology to cool more than 325,000 square feet across five buildings on its high school campus and reduce its peak energy consumption.
The school district, which was already using several solar systems, a 500 kW solar system and another five solar arrays totaling 400 kW to help power daily operations, needed a way to reduce energy consumption during expensive peak demand hours. Installing CALMAC’s IceBank® tanks at its high school campus has allowed the district to store cheap nighttime energy from the grid in the form of ice that can then be melted to cool buildings during the day. As a result, the district has reduced peak energy consumption by more than 20 percent, despite an increase in square footage and student population.
