Catherine MacGregor

Catherine MacGregor spent her first four years as CEO of Engie refocusing, simplifying, and divesting. In 2025, she signaled the next chapter had begun. The French energy giant posted $81.10 billion in revenue and $5.53 billion in net recurring income in 2025—at the top end of guidance—while adding 6.2 gigawatts of renewable and battery storage capacity, bringing its total renewable and storage installed capacity to 57.2 GW. Then MacGregor made her boldest move yet: the acquisition of UK Power Networks, the electricity distributor serving nearly 8.5 million customers in London and southeast England, instantly making Engie a dominant force in regulated electricity infrastructure. The roughly $14.1 billion deal closed in May 2026. Renewed as CEO in 2025, MacGregor, an engineer by training, is now overseeing $39.5 billion to $44.1 billion in gross capital expenditures between 2026 and 2028, targeting 95 GW of renewable and storage capacity by 2030; around 90% of the investments will go toward renewables, batteries, and infrastructure.
