SWARCO – Integrated Solar, Storage and EV Charging, Cross Hands


eSmart Networks partnered with SWARCO to deliver one of their smart charging projects, for Carmarthenshire County Council and the Welsh Government.

Together, our teams designed, engineered and delivered an innovative solution for the connection and construction of an integrated solar carport, battery storage and EV charging hub in the village of Cross Hands off the major A48 highway.


    • Combined installation of solar PV, battery storage and EV charger technologies on one site.
    • A project scope change was required to include on site drainage to minimise the impact on exisiting infrastructure.
    • There were existing HV and LV DNO cables buried at shallow depths passing through the middle of the hub site carriageway area.
    • A commercial solution was required to provide concession operation of the infrastructure.


We designed and installed bespoke low voltage equipment to control and manage the interface between the combined technologies.

SUDs (sustainable drainage system) installed to minimise the effects on the local infrastructure and be environmentally beneficial.

Using our NERS accreditation we completed all diversion works ourselves, ensuring a smooth end-to-end service for our customers.

We integrated SWARCO and eSmart PM and delivery teams to ensure seamless implementation and handover to the SWARCO network operation and support teams.

Quality and reliability are the foundation of the SWARCO Smart Charging brand and eSmart Networks provided meticulous project management and solutions to site challenges when scope changes were required.
