Define eligibility
Document asset capability, local priorities, participation rules, and the data needed to assess readiness.
Virtual power plant
Coordinate many local decisions as one dispatchable portfolio.
The Atmosphere VPP model preserves client ownership and site constraints while allowing an asset manager to form multiple VPPs and manage those VPPs as a portfolio under one account.

The model
Aggregation is not a claim about scale. It is a way to organise control.
Sites become useful to a wider programme when their eligibility, operating limits, availability, and owner intent can be understood together. Atmosphere models those boundaries before it models dispatch.
Illustrative sequence
Sites group into regional VPPs and expose coordinated pathways.
The markers and three VPP groups below are synthetic, and the sequence is qualitative. They do not show actual sites, customers, coverage, capacity, or dispatch activity.

East England
Contains data from NESO’s GB DNO licence areas (2024), used under the NESO Open Data Licence. Boundaries are approximate. Signals, markers, connections, and VPP groups illustrate an aggregation model only, not customer coverage, site locations, or portfolio size.
Participation pathway
Establish the guardrails before the event.
Build regional units
Organise eligible flexibility without removing the constraints that protect each participating site.
Control as one portfolio
Translate programme intent into governed actions with status, permissions, and recovery pathways visible.
Operator guardrails
Unified dispatch should never mean invisible control.
Operators need to know what was requested, what can respond, what is constrained, who can intervene, and how the portfolio recovers. Those questions shape the VPP design from the start.
- 01
- Site opt-in, limits, and priority rules
- 02
- Portfolio readiness and exception visibility
- 03
- Dispatch confirmation and recovery state
Operating scenarios
Follow the portfolio logic from observation to review.
The scenarios are qualitative and illustrative. They do not represent live assets, performance, capacity, or dispatch.
