Storage service specification builder

Define the service boundary, then check every constraint. Built-in values are resettable fictional teaching examples; results prepare further review.

Power and duty duration must be positive when supplied. Other numeric values may be zero; blank is distinct from zero. A zero recovery window remains an unresolved recovery request.

1. Delivered service and duty

Delivered serviceRequired net power (MW_e or MW_th for selected service)Continuous duty duration (h)Maximum permitted response / interruption (s)Zero is an explicit no-break requirement, not evidence that a device can achieve it.Planned non-overlapping events/yearNamed meter, service state and demand boundaryFor heat/cooling include temperature, flow and pressure/quality where applicable.

2. Protected reserve and recovery

Protected reserve at the same useful-output boundary (MWh)Available recovery window (h)Recovery supply, headroom and other concurrent commitments

3. Site evidence and follow-up

Site resources, space and permission constraintsDated evidence references and outstanding assumptionsNamed person responsible for follow-up

The entered reserve uses the same useful-output boundary and is additional protected inventory, not already deducted from task energy.

Methods, formulas and boundaries

This is a technology-neutral service specification, not an equipment sizing, reliability result or technology ranking. Empty numeric inputs remain unknown, while zero is preserved where meaningful.

For one constant duty, net service energy = required power × hours. Annual energy = duty energy × the declared non-overlapping annual event count. Annual duty hours cannot exceed 8,760 in this screen.

Task energy plus protected reserve is shown only when both are supplied and you confirm one useful-output boundary. It is not nameplate DC battery energy, water potential, fuel inventory or nominal thermal capacity.

A complete draft only means the requested fields have been supplied. Evidence is not independently verified. Losses, machine power, dynamic response, permissions and recovery need separate technical checks.
