Energy arbitrage

Charging a battery when electricity is cheap and discharging when it is expensive, the simplest revenue of grid storage. Peak shaving is the same idea applied to a site’s demand charges.

Frequency regulation

Rapidly injecting or absorbing power to hold the grid frequency at 50 or 60 Hz, a service batteries do better than any generator because they respond in milliseconds. It cycles the battery shallowly but very often.

Microgrid

A local network of loads, generators and storage — a campus, an island, a military base — that can run connected to the main grid or on its own. The battery is usually what makes islanded operation possible, forming the voltage and frequency and covering the gap while generators start or solar output dips.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.

Virtual power plant

Many small, distributed resources — home batteries, electric vehicles, rooftop solar, heat pumps — aggregated by software and dispatched together as if they were one power station. A few thousand home batteries add up to tens of megawatts of fast, controllable capacity that can trade energy and provide frequency services.
