Mutual Energy
Executive resilience report
Mutual Energy management · aggregated portfolio information only
Selected scenario and system consequence
30-day compound failure — Moyle unavailable, 2 generating units unavailable, 30 days, winter peak, low wind.
Indicative margin -510 MW (-7.5%) · Severe
This simplified screening model is not an electrical network simulation or blackout forecast.
Executive findings
- Mutual Energy own risk: Moyle unavailable for 30 days creates an illustrative £11.3m cash-flow sensitivity, separate from downstream losses.
- Electricity system: indicative resources are 6,290 MW against 6,800 MW demand, giving severe screening stress; this is not a blackout forecast.
- Downstream economy: 20 of 20 fictional businesses have potential exposure under explicit site-interruption assumptions, with £269.7m high-case gross economic exposure.
- Portfolio accumulation: 20 exposed insured businesses share island electricity system; aggregated potential insured exposure is £102.0m.
- Decision priority: faster restoration reduces duration-driven consequences; insurance or alternative financing addresses residual financial exposure and does not improve physical resilience.
Asset, dependencies and restoration
Moyle Interconnector · Scotland–Northern Ireland · rated technical capacity 500 MW. Rated capacity is not current available capacity or flow.
- Validate asset condition, failure mode, protection and control-system evidence.
- Confirm critical spares, specialist contractor mobilisation and repair access assumptions.
- Coordinate alternative imports, generation, storage and demand response with responsible third parties.
- Restoration is a selected assumption, not an automatically generated engineering forecast.
Mutual Energy own financial sensitivity
Synthetic assumptions only. Debt service sensitivity is 15× a £750k reference, not a credit rating, covenant compliance test or investment recommendation.
Downstream and portfolio accumulation
Downstream monetary severity is deliberately calibrated to approximately £100m insured exposure for the 30-day compound demonstration. Assumed loss amounts and policy limits are scaled 80×; this is not a validated forecast or a change to physical outage assumptions.
Potential downstream economic consequence before insurance
Simplified portfolio estimate; policy wording not verified
Residual economic exposure after illustrative insured estimate
20 of 20 fictional businesses potentially exposed · 20 potential correlated claims. Common dependency: Island electricity system (20 businesses).
Mitigation and residual risk financing
| Option | Restoration | System stress | Potential transfer | Residual retained + cost |
|---|---|---|---|---|
| No additional intervention | 30 days | Severe | £0 | £11.3m |
| Engineering / operational mitigation | 7 days | Severe | £0 | £8.57m |
| Mitigation + financial risk transfer | 7 days | Severe | £3.30m | £5.28m |
Mitigation changes assumed physical and operational outcomes. Insurance, retention and alternative financing allocate residual financial consequences; they do not improve physical resilience.
Assumptions and limitations
- All businesses, financial assumptions, loss estimates and portfolio outputs are fictional and illustrative.
- System stress, site interruption, business consequence and economic loss are separate model stages.
- No actual power flows, network constraints, dispatch, load shedding, engineering forecasts or claims are modelled.
- Actual financial and insured losses require verified financial records, engineering evidence and policy wording.
