EV Charging Infrastructure

The rapid expansion of EV charging infrastructure is needed to keep up with the uptake of electric vehicles and fleet decarbonisation and at Rock Power we are helping drive that expansion, connecting super hubs and ultra-rapid charging stations across the UK.

As an ICP we are able to offer an end-to-end service, managing both the DNO connection as well as the EV charging hub, meaning we can design and install substations, transformers, the Low Voltage network, SCADA communications and all civils.

Building Grid Resilience

As we move towards net zero carbon, we see increasing demand on the grid due to the electrification of heat and the transition towards cleaner fuels.

Our role as power connection specialists is crucial to green project growth and development, particularly around EV charging infrastructure and onsite power generation.

We offer three key services that enable businesses to access additional power from the Distribution Network, supporting decarbonisation objectives; new electrical connections, upgrade of electrical supply and transformer replacement.

‘Building Network Operator (BNO)’ – is a term which refers to the installation between the intake position and the customer’s own meter, often referred as the “laterals and risers”.

We offer a full design and installation service for electrical connections to apartment developments and mixed-use developments where individually metered supplies are required.  We can provide the electrical connection to the building, the internal Low Voltage mains or both.

We will liaise directly with the Distribution Network Operator (DNO) and ensure efficient delivery to achieve your energisation date.
