Cross-Cutting Capability
Solar Monetisation
Distributed solar PV across the residential portfolio generating export income, energy savings, and virtual power plant aggregation.
Every Rooftop is a Revenue Asset
The KRAIF portfolio targets thousands of residential rooftops across 12 UK regions. Each rooftop is a candidate for solar PV installation, transforming passive building fabric into active energy infrastructure. At portfolio scale, distributed solar generates four distinct revenue streams while materially reducing the carbon footprint of the housing stock.
Solar deployment is coordinated with the EPC retrofit programme. Roof condition is assessed, structural capacity confirmed, and PV installation scheduled as part of the integrated improvement works. This bundled approach reduces mobilisation costs and tenant disruption.
Four Revenue Streams
Self-Consumption Savings
Solar generation consumed on-site directly reduces tenant energy bills. This is the most valuable use of solar output, avoiding both wholesale energy costs and grid charges.
Export Income
Surplus generation exported to the grid earns income through the Smart Export Guarantee. As portfolio scale grows, we negotiate bespoke export tariffs above the SEG floor.
Virtual Power Plant Revenue
Sanufa aggregates distributed solar across the portfolio into a virtual power plant, enabling participation in grid balancing services, demand-side response, and wholesale market trading.
Avoided Carbon Costs
Solar generation displaces grid electricity and its associated carbon intensity. As carbon pricing mechanisms tighten, this avoided cost becomes an increasingly material benefit.
Sanufa Virtual Power Plant
Individually, a residential solar installation generates modest returns. Aggregated across thousands of homes through the Sanufa platform, the portfolio becomes a significant distributed energy resource. Sanufa optimises self-consumption, manages export scheduling, and participates in grid services markets that are inaccessible to individual installations.
As battery storage costs decline, Sanufa will integrate home batteries into the virtual power plant, adding time-shifting capability and further grid services revenue. The platform architecture is designed for this evolution.
ROI Through Energy Economics
Solar PV installations typically achieve payback within 7-10 years, with a 25-year panel lifespan delivering 15-18 years of post-payback income. When combined with EPC retrofit synergies and Sanufa aggregation, the effective return on solar investment materially exceeds standalone deployment economics.
