The atlantic county, N.J., Utilities Authority wastewater treatment plant in Atlantic City brought its renewable-energy battery-storage system (see photo above) on line on April 16, allowing for the capture of up to 1 megawatt per hour of energy produced by the site’s 7.5-MW wind farm and about 500 kilowatts from solar panels. The New Jersey Board of Public Utilities awarded a $417,000 grant to help fund the project under the state’s clean energy program, the first time such financing has been used for a battery-storage system. Viridity Energy Solutions Inc. was EPC contractor and will own and operate the system. Design firm RETTEW was the project’s design-build manager. Calvi Electric was electrical contractor, and Johnson Controls provided the system itself. The treatment plant now obtains 60% of its own daily energy from the onsite wind and solar sources.
