Our Consultancy & Design Development
Before construction commenced, EvoEnergy provided detailed consultancy and design development to refine the HyperHub concept into a fully deliverable, construction-ready scheme.
City of York Council had secured funding for the project, however final construction finance required the design to reach a defined level of technical maturity and cost certainty before it could be released. We developed the scheme through to RIBA Stage 3–4, providing the technical validation, risk reduction and specification detail required for fixed-price procurement.
Drawing on our experience from the earlier HyperHub projects, we embedded lessons learned into this phase, particularly around grid capacity risk, infrastructure sizing and projected EV demand growth. Grid constraints remain one of the biggest barriers to EV infrastructure rollout in the UK, so early engagement with the Distribution Network Operator formed a critical part of our consultancy scope. Through proactive grid assessments and technical dialogue, we de-risked connection uncertainty and validated the most viable configuration for the site.
Our consultancy services included specialist site surveys, ground condition assessments, detailed layout optimisation, technology due diligence and specification writing. All equipment was reviewed to ensure it was commercially available, supply-chain resilient and aligned with long-term operational requirements. This ensured the project could progress confidently into procurement without delays or design rework.
In addition, we reviewed compliance requirements including PAS 1899 accessibility standards, ensuring the public-facing charging hub met regulatory and inclusion expectations from the outset.
Energy Modelling & Future-Proof Strategy
To validate the technical and commercial case, total consumption and PV generation data were fed into a 5-direction site energy model. This incorporated fluctuating demand, variable solar generation, projected EV charging growth and multiple battery capacity and power scenarios.
The modelling refined the multi-technology system configuration and allowed us to stress-test performance under different grid and usage conditions before installation. It ensured the final design was not only technically robust but financially optimised.
From best estimates, our model showed that the amount of self-generated solar energy used onsite would increase by 50% in 2021 to almost 100% in 2030, meaning that as EV uptake increases, all energy produced onsite will be self-consumed.
This forward-looking approach created more than a single-site solution. It further refined a repeatable HyperHub blueprint that can be scaled across future locations. The modelling framework, grid strategy and technology configuration now provide a strong foundation for the Council’s wider EV infrastructure programme.
By providing technical certainty, commercial realism and long-term strategic insight, EvoEnergy enabled the Council to move confidently from concept to construction while protecting public investment and reducing delivery risk.
