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.

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.

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.
