The challenge
Operators have to keep a grid stable as inverter-based renewables displace the spinning inertia of thermal plant, peaks keep growing, and transmission and distribution assets age. The old answers — build a peaker, rebuild a constrained line — are slow, capital-heavy and increasingly hard to permit.
And the physics has changed: frequency events now happen faster than thermal units can respond. Storage is the one asset that's fast, modular and sited exactly where it's needed.
Where storage pays off in Utilities & Grid Operators
Frequency response & ancillary services
Deliver sub-second fast frequency response, regulation and reserves — faster than any thermal unit can ramp.
Peak capacity & renewable firming
Meet peak demand and firm wind and solar without building a new peaker plant.
T&D deferral
Site storage at the constraint to relieve congested lines and substations, deferring costly upgrades for years.
Black-start & system strength
Provide restart capability after an outage, plus grid-forming inertia and reactive support to strengthen a weak grid.
What a Hanum deployment looks like
Grid-scale container arrays are sited at substations or network constraint points, configured grid-forming or grid-following as needed, and dispatched by the control room or market signals. The system scales to tens or hundreds of MWh.
| Siting | Substation / network constraint |
| Mode | Grid-forming or grid-following |
| Services | FFR, reserve, firming, black-start |
| Scale | Tens to hundreds of MWh |
Outcomes you can expect
- Sub-second frequency support beyond thermal capability
- Deferred T&D capital at congested nodes
- Higher renewable hosting capacity on the network
- New market revenue from ancillary and capacity services

Common questions for Utilities & Grid Operators
Both. Grid-following suits energy and ancillary duty on a strong grid; grid-forming provides inertia, system strength and black-start on weak or islanded networks. We configure to your interconnection study.
Yes, where specified. A grid-forming configuration can energise a dead network and support restoration, in coordination with your system operator's black-start plan.
The same asset can stack energy arbitrage, frequency response, reserves and capacity payments. The controller co-optimises across the services your market offers to maximise total return.
Recommended systems
Utilities deploy the Container 5000 in parallel strings, scaled to the capacity and services your network and market require.
