The challenge

Different buildings. Different demands. One investment decision.

Neath Port Talbot needed a clear, investment-grade decarbonisation pathway across buildings with different demand profiles and site constraints. They required evidence to prioritise technologies offering the greatest carbon impact and financial value.

The solution

Model the estate in detail, then rank the opportunities

Quantaco modelled the estate at half-hourly resolution, assessing renewable generation potential, heating profiles, system constraints and regulatory viability.

39–72% modelled carbon reduction across the portfolio

Quantaco identified major opportunities to reduce emissions and cut fossil-fuel reliance across the council estate.

What the modelling revealed

Heat pump potential

Significant opportunity to displace gas consumption and reduce fossil-fuel reliance.

~84% on-site electricity self-sufficiency

A large education site showed potential to achieve around 84% on-site electricity self-sufficiency.

High-yield solar carports

Civic sites with extensive parking showed strong potential for solar carport deployment.

Estate types assessed
