Levelise will deliver the long-term optimisation and flexibility management platform for the 576-home Cosmeston Farm development in Penarth, enabling residents to earn revenue from their home energy systems by participating in flexibility markets.
The landmark scheme, delivered by Barratt Redrow, is the UK’s largest net zero carbon housing development, with every home equipped with solar PV, a networked ground source heat pump, battery storage and an electric vehicle charge point.
Through the Levelise platform, these distributed energy assets will be aggregated and optimised to participate in flexibility markets, enabling homes to trade energy services with the grid and generate revenue that flows directly back to residents.
Steve Day, Product Director at Levelise, said: “Cosmeston Farm not only delivers zero carbon homes, but homes that earn. Networked ground source heat pumps and battery storage at this scale create a genuine grid asset, and homeowners should benefit from that value, not just absorb its cost.”
By orchestrating when batteries charge and discharge, when heat pumps pre-heat homes and when EVs draw power, the platform aligns household energy use with grid needs, lowering system strain while unlocking new income streams.
The project signals a shift in how large-scale residential developments are operated. Rather than viewing low-carbon technologies solely as a compliance requirement, Levelise’s model treats them as long-term performing assets.
As the UK prepares for mass heat pump adoption and increasing electrification of transport, Cosmeston Farm is expected to become a flagship site for national policy -demonstrating how next-generation energy systems can transform communities, cut carbon and support the UK’s transition to a low-cost, low-carbon housing future.
