In Front Of The Meter Systems
Battery storage systems are being deployed at several levels of the electricity value chain, including at the transmission, distribution, and consumer levels. Energy market applications are commonly differentiated as behind-the meter (BTM) or in-front of the meter (FTM).
In Front-of-the-meter battery storage systems – also referred to as utility scale or grid-scale battery storage - can be connected to distribution/transmission networks or power generation assets. Utility-scale storage capacity ranges from several megawatt-hours to hundreds. Lithium-ion batteries are the most prevalent and mature technology.
Battery storage increases flexibility in power systems, enabling optimal use of intermittent electricity sources like solar photovoltaic (PV) and wind energy.
