What do solar and energy storage developers need to know?

It’s important that solar and energy storage developers have a general understanding of the physical components that make up an Energy Storage System (ESS).

What type of batteries are used in stationary energy storage?

For this blog, we focus entirely on lithium-ion (Li-ion) based batteries, the most widely deployed type of batteries used in stationary energy storage applications today. The International Energy Agency (IEA) reported that lithium-ion batteries accounted for more than 90% of the global investment in battery energy storage in 2020 and 2021.

How does the energy management system work?

The energy management system handles the controls and coordination of ESS dispatch activity. The EMS communicates directly with the PCS and BMS to coordinate on-site components, often by referencing external data points.

What is the composition of a battery?

The composition of the battery can be broken into different units as illustrated below. At the most basic level, an individual battery cell is an electrochemical device that converts stored chemical energy into electrical energy. Each cell contains a cathode, or positive terminal, and an anode, or negative terminal.

Are lithium-ion batteries the future of energy storage?
