Behind-the-meter and front-of-the-meter

Where a storage system sits relative to the customer’s electricity meter. Behind-the-meter batteries in homes, shops and factories serve the site first — solar self-consumption, backup, cutting demand charges; front-of-the-meter systems connect directly to the grid and earn from wholesale trading and grid services at utility scale.

Demand response

Changing electricity consumption in answer to a price signal or a grid operator’s request, rather than adding generation. Pausing a fleet’s charging during an evening peak, or letting a home battery carry the house load for an hour, are typical examples; aggregated, such flexible loads can be paid as grid services.

FERC Order 2222

The US Federal Energy Regulatory Commission’s order of September 2020 requiring regional grid operators to let aggregations of distributed energy resources — batteries, electric vehicles and their chargers, rooftop solar, demand response — take part in wholesale electricity markets, with a minimum aggregation size of no more than 100 kW.

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.

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.

Vehicle-to-grid

Discharging a vehicle’s battery back into a house or the grid through a bidirectional charger, so parked cars act as storage. Vehicle-to-load and vehicle-to-home are the simpler forms that power appliances or a house directly.
