Design, Assembly, Installation & Commissioning of High Voltage Protection Systems & Control System Integration Solutions


Originally called IDEC, the company was founded in Teesside in 1976. The company originally specialised in Instrumentation and Electrical Engineering Design and Project Management. Since then, it has expanded over the decades with over 150 staff and 5 offices across Northern England and Scotland. As IDEC Technical Services Limited, it covered the following business areas:

  • High Voltage Protection Systems
  • High Voltage Protection Refurbishments
  • High Voltage Substation Design
  • Substation Installation and Commissioning Services
  • Instrumentation and Control Systems & System Integration
  • The Manufacture of HV Packaged Substations and Control Rooms Including Control and Electrical protection panels

In 2022, Keltbray Group acquired IDEC and the company was renamed to Keltbray-IDEC Limited. The future sees the company become part of a broader power engineering offering within Keltbray Energy, and part of Keltbray’s plan for strategic growth in the utilities and power sector.




 Keltbray-IDEC’s  aim is to work in partnership with the client in the design, management, and installation and commissioning of Control and Protection systems, meeting the high expectations of today’s market place. Within the engineering and construction business IDEC recognises that profitability and safety rely critically on the following objectives:

  • Quality of Engineering
  • Effective use of Resources
  • Completion of the works on Time


Keltbray-IDEC has the technical ability and in-depth knowledge to provide totally integrated control systems for either HV Protection or Control System Integration. This involves the combination of plant control with state of the art “intelligent” relay systems, giving communications and process control, load control, load shedding, tariff optimisation, generator control and automatic supply restoration.

Our engineers have designed, built, and commissioned most functional types of protection and system integration control schemes and are conversant with the major manufacturers of hardware and operating systems.

Our commitment is to identify the need accurately, providing our customers with the most flexible and cost-effective solution, giving full account of existing control systems and future expansion possibilities.

As a compliment to the above we have a fully equipped workshops and test facilities for the assembly of Control Panels, MCCs and HV Protection Panels, together with the programming and configuration of the PLC, RTUs and SCADA systems.
