Enel
Italy's former state electricity monopoly, created by the nationalisation law of December 1962, listed in November 1999 and still ~23.6% owned by the Italian Treasury (verify current %), which became one of the world's largest private electricity companies by customers (~70m end users, company claim) and the largest private owner of renewable capacity (company claim) by buying Spain's Endesa in 2007 and then spending a decade building wind, solar and networks across Latin America, Europe and North America. The growth was paid for with debt: net debt reached ~€60bn at the end of 2022 (company), and the group spent 2023–25 selling assets in Argentina, Peru, Romania, Russia and elsewhere under a new chief executive, Flavio Cattaneo, before presenting a ~€53bn 2026–28 plan in February 2026 tilted toward regulated grids (~€26bn) and "Tier 1" countries, the United States among them (company). In the US, Enel North America (Andover, Massachusetts) runs ~5 GW of wind and solar and ~1.3 GW of batteries, mostly in Texas (ERCOT), Oklahoma and Kansas (company, Feb 2025), plus a demand-response business built on the 2017 purchase of Boston's EnerNOC. Enel's story is matched capital gone wrong and then repaired: a utility balance sheet stretched to fund global, part-merchant growth, and a reset that bought back investor trust by shrinking.
