Is Bess a viable form factor?

Several BESS developers and operators has spoken to recently said the 20-foot 5MWh form factor was the only viable product for their projects. Prevalon (until recently the BESS arm of Mitsubishi Power Americas, said that the cost reductions have made any other form factor virtually untenable.

What does Bess stand for?

The project is being developed by Copenhagen Infrastructure Partners (CIP) in partnership with UK-based energy storage developer Alcemi. The battery energy storage system (BESS) project will be located on 15.8 hectares (ha) of land. Credit: Phonlamai Photo/Shutterstock.com.

How does a Bess work?

A BESS is typically comprised of battery cells arranged into modules. These modules are connected into strings to achieve the desired DC voltage. The strings are often described as racks where the modules are installed. The collected DC outputs from the racks are routed into a 4-quadrant inverter called a Power Conversions System (PCS).

Can a Bess be used as a solar PV inverter?

The PCS used for the BESS will need to comply with the same standards as solar PV inverters (such as IEEE-1547-2018). The concern that the utility has, however, is possible reactive and/or short circuit power contributions the BESS could still present to the grid.

How do I integrate a Bess with a microgrid?

Integrating a BESS within the context of a microgrid with respect to the electrical utility is often like interconnecting other DER, such as generators and PV solar farms. The PCS used for the BESS will need to comply with the same standards as solar PV inverters (such as IEEE-1547-2018).
