Using battery storage supports the reliability of the local distribution network. A battery energy storage system charges from the electric grid or solar power plant and then discharges that energy to the electrical grid during peak demand when consumers need power the most.

The proposed Project BESS consists of lithium-ion batteries, which are the same batteries used to charge smart phones and electric cars. This battery technology has been proven to be stable and reliable.

Battery modules have an anticipated lifespan of approximately 20 years. Additional operation can be expected past this lifecycle with proper maintenance and battery replacements as required. At the end of the modules lifespan, Enerfin will follow the manufacturer’s recycling guidelines and the Project lands will be returned to its former equivalent use.

The Project is fully fenced and there is no access allowed to the facility by the general public. The proposed Project BESS will be self-contained units placed on concrete pads. Each battery contains internal temperature control, cooling systems, and electrical safety systems which enable it to automatically shut down if is not performing as expected. A BESS-specific emergency response plan (ERP) will be further outlined in the overall Project ERP. If an alarm is triggered at a battery site, facility operators are notified immediately, and local emergency response providers are notified to implement the ERP. As part of Enerfin's ERP, the Project will follow safety and applicable regulations and will be compliant with applicable safety codes and standards. Enerfin will be engaging with local fire and emergency response resources to prepare a site specific ERP that satisfies the regulatory requirements and implements safety measures to minimize potential safety risks associated with the facility. A working copy of the site-specific ERP will accompany the AUC application and be made available to the public at the time of filing.

A typical BESS includes battery modules, sensors and controls, inverters and transformers, all housed in weather proof containers.

Battery modules are most commonly neutral in color and are comparable in shape to a shipping container. Visual impacts have multiple ways to be mitigated and will be discussed with stakeholders and implemented where applicable. Exact dimensions are yet to be determined as final equipment has not yet been selected.
