Measured Portfolio Impact

Conservative performance modelling under a standardised storage-led baseline.

Stability, not speculation.

Under the controlled baseline:

  • ~3,000 kWh annual generation per home
  • ~60% self-consumption enabled by storage
  • ~1,800 kWh offset against tenant demand
  • ~£500 annual tenant bill stability (current tariff reference ~28p/kWh)

This modelling assumes:

  • 3.68kW export limitation
  • Conservative UK yield assumptions
  • No tariff inflation modelling
  • No optimisation uplift

Outcomes scale proportionally across the portfolio.

Illustrative 500-home deployment

  • ~1.5 GWh annual generation
  • ~900,000 kWh self-consumed
  • ~600,000 kWh controlled export
  • ~£250,000 annual tenant stability

Over 20 years (static tariff reference, pre-lifecycle adjustment):

  • ~£5 million cumulative stability

All modelling remains conservative and baseline-consistent.

Carbon displacement under current grid intensity.

At the current UK grid carbon intensity:

  • ~0.5–0.6 tonnes CO₂ avoided per home annually

Carbon displacement is generation-based and will reduce proportionally as grid decarbonisation progresses.

Long-term modelling accounts for declining grid carbon intensity through 2030.

Portfolio deployment improves capital efficiency.

Retail benchmark per home £9,500 – £14,000

Portfolio deployment range: ~£7,500 – £8,800 per home

Scale reduces:

  • Procurement margin
  • Installation overhead
  • Logistical inefficiency
  • Retail markup

Cost efficiency improves without altering baseline architecture.

Conservative modelling reduces delivery risk.

No uplift scenarios are embedded.
No peer-to-peer redistribution assumptions are included.
No speculative tariff forecasting is applied.

Impact is modelled within current regulatory and grid frameworks.
