ABB has completed its acquisition of IPEC Limited, bringing the Stockport-based specialist in partial discharge monitoring into its global electrification service organisation. The deal adds around-the-clock diagnostic monitoring and analytics to ABB’s predictive maintenance offer, with the combined business targeting critical electrical infrastructure in sectors where unplanned downtime carries a high operational and financial cost.
IPEC has built its position around detecting partial discharge — the small electrical sparks that can signal the early stages of insulation failure in high-voltage assets. That capability is relevant across substations, data centres, airports, utilities, hospitals, and industrial plants, where operators are under pressure to extend asset life while reducing disruption. ABB said the acquisition strengthens its move away from reactive maintenance and towards condition-based service models built on earlier fault detection and clearer asset intelligence.
The strategic logic is straightforward. Electrification systems are becoming more digital, more heavily loaded, and more business-critical at the same time. In that environment, online monitoring can shift maintenance windows, reduce avoidable outages, and give operators better visibility across distributed assets. ABB has said partial discharge is a leading cause of equipment failure, and IPEC’s monitoring systems and analytics are intended to identify developing faults before they become shutdown events.
Dr Colin Smith, Managing Director of IPEC, said: “This transaction has been in the making for more than two years, so we are delighted to officially sign the contract and become part of ABB, one of the world’s most respected names in electrification.”
IPEC was founded out of the University of Manchester and now operates internationally, with the business having expanded from domestic utility clients into wider industrial and infrastructure markets. ABB said the company employs around 70 people across operations including the UK, the Middle East, Sweden, and the US, with data centres now representing its largest and fastest-growing market segment.
The transaction also underlines the value now being attached to specialist diagnostics businesses in electrification. Corporate finance support and tax structuring advice to IPEC’s owners was provided by DJH, while legal advice to shareholders came from Bermans. For ABB, the acquisition is another step in building service-led revenue around installed electrical assets. For IPEC, it provides a route to broader international reach inside a much larger installed base.
