## Summary

This public procurement process involves the National Grid Electricity Transmission PLC, based in London, UK, which has issued a direct award for the purchase of CBtect Portable Circuit Breaker Monitoring units. The procurement, under the category of sensors, is tailored to the utilities sector and was initiated due to a lack of competition for similar technology. The contract pertains to the supply of 10 units with potential for additional purchases based on operational demands. The award was made to Elimpus Limited, a small to medium-sized enterprise located in Motherwell, Scotland. The planned contract period commences on 9 January 2026 and will conclude on 31 March 2031, with the potential for extensions.

This tender presents significant opportunities for businesses specialising in innovative monitoring and operational maintenance technology. The need for a portable, non-invasive monitoring solution tailored for circuit breakers underlines the competitive advantage held by firms capable of providing such unique solutions. Small to medium-sized enterprises, particularly those with expertise in sensor technology and utilities management, are well-positioned to benefit from future opportunities of this nature, as demonstrated by the successful award to Elimpus Limited.

## Notice

Supply of 10 CBtect portable circuit breaker monitoring units, plus licenses for connection to servers and warranty. Option for up to an additional 10 CBtect units depending on operational requirements included.

### Procurement Information

Competition is absent for technical reasons and there are no reasonable alternatives (Procurement Act 2023, Schedule 5, paragraph 6): CBTect is a unique technology designed following an innovation project to enhance National Grid's ability to capture multiple aspects of condition data of in-service circuit breakers. The CBTect units being purchased have been developed as a portable monitoring system that does not require an outage to install and will provide flexibility when assessing the condition of, and subsequent maintenance of, circuit breakers. CBTect can identify a range of fault conditions including: Timing defects, interrupter defects, failing grading capacitors, mechanism damping problems and SF6 contamination. National Grid has not identified a reasonable alternative portable product that can analyse the range of fault conditions required and does not require an outage to be installed.
