Programme context
Centrica moved a Power Platform estate of more than 1,100 applications into a more governed operating model using Managed Environments, application lifecycle management and strengthened maker controls.
Why this matters: This record identifies a named Irish or UK organisation, a bounded predecessor state, a destination platform, an affected workload and a source-stated operational stage.
Migration timeline
| Date or stage | Milestone | What changed | Evidence status |
|---|---|---|---|
| Predecessor state | Rapid maker growth | A large estate depended heavily on default environments and uneven lifecycle controls. | Source stated |
| Governance transition | Managed Environments adopted | Centrica introduced stronger environment, ALM and maker governance. | Source stated |
| 19 June 2026 | Dated publication | Microsoft published the operational case. | Source stated |
Workload migration matrix
| Workload | Predecessor | Destination | Status by 27 Jul 2026 |
|---|---|---|---|
| more than 1,100 low-code applications, automation and maker governance | large Power Platform maker estate with default-environment dependence and inconsistent application lifecycle controls | Power Platform Managed Environments with governed ALM and environment controls | Operational |
Implementation and architecture
- Managed Environments strengthened administrative controls.
- Application lifecycle management improved deployment governance.
- The operating model also references Power Apps code apps and Copilot Studio.
Known unknowns and contradictions
- The exact number of applications moved into each governed environment is not stated.
- The source does not claim every app was rebuilt.
- No complete retirement inventory for prior tools is provided.
No missing fact is inferred to broaden the source-supported platform-change claim.
PlatformTrace analysis
The dated source supports operational governance changes across the named Power Platform estate. It does not state that every application was rebuilt or that every developer tool was replaced.
Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
