28 years ago this year (2025) Powersystems became the first fully accredited Independent Connection Provider (ICP) in the UK, under what was then called the Accredited Contractor Scheme; under OFGEM’s ‘Competition in Connections’ is now commonly known as the National Electricity Registration Scheme (NERS).
This scheme is operated by Lloyds Register on behalf of the UK Distribution Network Operators (DNOs).
The NERS accreditation lists both the location coverage and the scope of works an ICP can carry out at the different voltages.
Accredited up to 132 kV, Powersystems high voltage electrical engineering company specialise in grid and network connections and contestable works, offering an alternative to using the local Distribution Network Operators.
For 48 years Powersystems, who started trading in 1977, have continued to build long term relationships with clients to provide the optimal engineering solution.
Still ground-breaking in 2021, Powersystems lead the way on some of the UK’s first of its kind electrical contracts like; the first greener grid park project in Moray, Scotland. The project, located near the Scottish and Southern Electricity Networks transmission substation at Keith, will include two large rotating stabilisers designed to provide stable flows of energy through the grid network, helping to increase the amount of renewable energy transmitted on the system and prevent power blackouts. As well Powersystems are also providing the electrical cable installation works contract for the world’s largest offshore wind farm Dogger Bank, under construction today.
It is with thanks to our in-house expertise, we provide a trusted point of contact throughout the project lifecycle, which helps to minimise the risk of schedule delays and helps us to maintain project quality, whilst delivering a safe and sustainable solution.
We can assume responsibility for the following elements of a project.
- Design of a connection from the ‘Point of Connection’ (POC) to the site
- Supply of all cables, switchgear, and transformers required to make the connection
- Civil engineering works including excavation of the connection route, cable laying from the POC to the site, the installation of concrete bases for substations and other electrical equipment.
- Construction and installation of electricity substations
- Commissioning of the installed connection assets
- Full project management of all works
- Full project hand back including as-built records (OEM) for all connected assets (digitally supplied)
Because Powersystems specialise in both high and low voltage distribution systems, we can include the following within our infrastructure works:
Electrical design of Distribution Networks covering:
- HV cable networks (11 kV, 33 kV, 66 kV, 132 kV)
- Substation installation (11 kV, 33 kV, 66 kV, 132 kV)
- Overhead wooden pole (11 kV, 33 kV)
- Cable jointing (LV, 11 kV, 33 kV, 66 kV, 132 kV-PM)
- Cable laying (LV, 11 kV, 33 kV, 66 kV, 132 kV)
- Civil works
- Substation installation (11 kV, 33 kV, 66 kV, 132 kV)
