The Brief
A regional water corporation has been progressively implementing behind-the-meter (BTM) solar photovoltaic (PV) generation system installations across its operational sites over the last five years and requires the addition of an Battery Energy Storage Systems (BESS) to increase efficiency and garner revenue.
The Problem
There are four PV generation sites, which produce a relatively substantial excess energy that is exported back to the grid to receive Feed-in Tariff (FiT) credits; however, the water company is not getting the best from its on-site solar PV generation as the FiT credits are of diminishing value.
Our Solution
- Six 233kWh BESS for installation behind-the-meter (BTM) at four PV sites
Deployment
The purpose of the BTM BESS is to capture the excess renewable energy generated, offsetting the site’s usage during high-generation periods and discharging the stored energy to displace grid consumption during low-generation periods.
The BTM BESS will provide a backup power supply to the site in the event of a grid outage.
Outcome
These BESS will be operationally integrated with the existing onsite PV generator to operate as a complete, market-deployable distributed energy resource (DER) providing additional operating revenue streams and cost savings.
