Battery Storage Project

Home > Green Initiatives > Battery Storage Project

A one-megawatt (MW) renewable energy storage battery is located at ACUA’s Wastewater Treatment Facility to help balance the relationship between ACUA's renewable energy projects and the electrical grid. It is the first public renewable energy storage battery to become operational in New Jersey.

Battery


Renewable energy sources are more intermittent than traditional sources like natural gas or coal, and existing electrical infrastructure is still adapting to handle them. Batteries are one tool that will help ensure renewable energy and the electrical grid can work together reliably and effectively by managing supply and demand.

Excess energy generated by our renewable energy projects -- up to one megawatt -- can be stored in the battery, which will help ease pressure on the grid. In times of high demand, the grid can pull energy from the battery for use. 

The demonstration project showcases what is an important tool in supporting the growth of renewable energy across the U.S.

Benefits of Battery Storage

  • Batteries can support overall electrical grid operations
  • Reduce greenhouse gas emissions
  • Improves the integration of renewable energy resources
  • Provides additional capacity to the grid in times of need
  • Can be charged during off-peak times, such as mornings, and then discharged during peak times, such as hot afternoons, to reduce peak energy needs
  • Can be placed strategically in locations on the circuit where they are needed most, with modular designs that address space and other constraints

Project Partners

The project is owned and operated by Viridity Energy, and ACUA serves as the site host. It was made possible through a $300,000 grant from the New Jersey Board of Public Utilities (NJBPU).

Johnson Controls provided the battery system. RETTEW provided the electrical and construction services. Calvi Electric served as the local contractor on the project.
