French Utility Engie to Acquire UK Power Networks
French utility company Engie has agreed to purchase UK Power Networks (UKPN), the owner of electricity cables and power lines across London, the south-east, and the east of England, in a transaction valued at £10.5 billion.
Headquartered in Paris, Engie announced on Wednesday that the acquisition represents a "major milestone" in its ambition to become the "best energy transition utility." The deal will see Engie take ownership of the electricity network operator that manages approximately 192,000 kilometers of power lines serving 8.5 million customers across London and southern and eastern England.
UK Power Networks has been owned for the past 15 years by a Hong Kong-based conglomerate founded by billionaire business magnate Li Ka-shing. Engie's acquisition marks a significant shift in ownership of this critical infrastructure.
Engie CEO Comments on Strategic Importance
"The acquisition of UK Power Networks marks a major milestone in the implementation of our strategic priorities.
By reinforcing our position in electricity networks, it confirms our ambition to become the best energy transition utility and will support our growth momentum while improving our risk profile," said Engie's chief executive, Catherine MacGregor.
Context Within UK Electricity Network Market
This acquisition comes nearly a year after the UK’s competition watchdog approved Spain’s Iberdrola to acquire an 88% stake in Electricity North West (ENW) through its UK subsidiary Scottish Power. That deal valued ENW, which serves nearly 5 million people in the north-west of England, at £5 billion. ENW has since been rebranded as SP Electricity North West.
Electricity distribution network companies in Britain operate the power lines and infrastructure across six geographical monopolies. These companies are currently about halfway through a plan to invest over £22 billion in upgrading and expanding their networks by 2028. This investment is part of a five-year programme approved by the industry regulator.
Importance of Investment for UK’s Energy Transition
The investments, which are considered crucial, aim to enable Britain to connect sufficient new low-carbon generation sources, battery storage, and electric vehicle charge points. These developments are essential to support the UK’s goal of reducing reliance on fossil fuels and increasing the use of green electricity.
