New Connections Support

 

  • Negotiating grid connections for commercial clients, both for load customers and generating customers including, industrial, commercial and the public sector

  • Overseeing the connection of Distributed Generation plant in compliance with ENA ER G99

 

National Electrical Registration Scheme (NERS)

 

We are registered to undertake the design of connections to the public electricity network under the National Electrical Registration Scheme (NERS), using the Competition in Connections (CIC) process.

We are able to design the contestable element of any connection to the UK Distribution Network Operators’ (DNO) standards allowing the customer to appoint an approved contractor to undertake the installation of the works.

This enables the client to have increased control in the design input on the contestable part of the installation and may offer reduced delivery times along with cost savings.

We can also provide design services to Contractors registered for the installation of contestable works, enabling the contractor to have access to full design services, as part of their offer.

Featured power systems projects

 

JCB Heavy Products Plant


CPW designed the MEP building services for JCB’s brand new bespoke 450,600ft2 production facility which is capable of producing 8,000 excavators a year. 

This heavy products plant is set in Uttoxeter, Staffordshire and is the only facility in the UK which produces large tracked and wheeled excavators from seven to 46 tonnes.

New Cross Hospital

Following a review of the hospital’s electrical infrastructure and subsequent power system analysis with the help of a digital twin of the network, it was highlighted that the current infrastructure is not equipped to support the Trust’s decarbonisation plans for this site.

Kettering General Hospital

Kettering General Hospital

CPW have been appointed to support the redevelopment of Kettering General Hospital under the Health Infrastructure Plan (HIP2) through the replacement of aging site-wide energy infrastructure.

Frequently asked questions

  • Power systems are vast networks of components working together to generate, transmit and distribute electricity. First electricity is created, and power plants can use various sources like fossil fuels or renewable energy. It is then transported over long distances and delivered to homes and businesses. Power systems are complex and need to be constantly monitored and controlled to ensure they operate safely and reliably.

  • Power system engineers provide support for projects that require specialist power systems engineering input or developing detailed designs for pure power system projects. Their duties may include network modelling and simulation, visiting sites to inspect installations, developing technical specifications, cable network design and protection studies.

  • Power system consultants support by producing surveys of existing networks and due diligence analysis. They will also create a replacement strategy along with asset planning. They support for FAT, SAT and equipment commissioning
