Powersystems , a leading high-voltage electrical engineering contractor, is proud to reaffirm its position as a trusted partner for developers seeking reliable, compliant, and efficient grid connections.
As the first Independent Connection Provider (ICP) accredited under the Lloyd’s National Electricity Registration Scheme (NERS), Powersystems has maintained this status for 29 years, delivering high-quality, contestable connections for projects across wind, solar, battery storage, and other renewable and low-carbon technologies.
What is an ICP?
An Independent Connection Provider (ICP) is a specialist contractor authorised to design, construct, and commission electrical connections to the UK electricity grid on behalf of developers. ICPs operate under the Competition in Connections framework, providing an alternative to Distribution Network Operators (DNOs), giving developers greater choice, flexibility, and transparency when connecting their projects.
Powersystems and the NESO Framework
With the transition to the National Energy System Operator (NESO) arrangements, Powersystems continues to deliver contestable high-voltage connections up to 132 kV in line with the latest national regulations and assurance standards. Working closely with NESO, transmission operators, and distribution network owners, Powersystems ensures that connections are timely, compliant, and technically robust.
