Whether a renewable energy project, your industrial/commercial premises or a generation scheme, Powersystems are able to provide a competitive connection offer.

Our teams of engineers will manage the entire connection process from initial application, design, construction and commissioning, through to final energisiation and adoption.

From application to energisation

Lloyds Register is responsible for assessing and accrediting Independent Connections Providers (ICPs) under the National Electricity Registration Scheme.

Under our full scope of National Electricity Registration Scheme (NERS) accreditation we are able to undertake connection design work, cable installation, cable jointing, substation design and construction, switchgear and transformer installation and testing and commissioning services. Powersystems carry out contestable works from low voltage up to 132 kV.

As an Independent Connection Provider (ICP) Powersystems have been assessed and accredited nationally by Lloyds register to carry out:

This accreditation enables us to provide grid connections in all areas of the UK, at voltage levels up to 132 kV and as a result we have successfully completed a large number of projects.

Powersystems celebrate 26 years as the UK’s first Independent Connection Provider.

We have civil construction capability which enables us to offer clients a ‘turnkey’ connection service to include trenching works, directional drilling, substation building, construction and design from small 11 kV substations up to 132 kV primary substations.

What is an Independent Connection Provider (ICP)?

ICP stands for Independent Connection Provider, and refers to an accredited company that can build electricity networks to the specification and quality required by Distribution Network Operators or an Independent Distribution Network Operators.

Powersystems have carried out a large number of grid connections for a varied clientele, ranging from Data Centres, Industrial Customers, Formula One Racing Teams, Health Trusts, Water Industry, Major Film Studio/Visitor Attraction and the Renewable Energy Sector.
