A private equity consortium led by Global Infrastructure Partners closed its $33 billion acquisition of AES Corporation, transferring control of 33 gigawatts of power generation capacity and regulated utility operations serving 2.6 million customers across fifteen U.S. states and four Latin American countries. The transaction, which includes assumption of $7.2 billion in net debt, represents the largest utility sector take-private since Brookfield's $14.3 billion Origin Energy bid in late 2024.
The consortium—GIP alongside an undisclosed group of institutional co-investors—paid $87.50 per share in cash, a 22 percent premium to AES's ninety-day volume-weighted average price at announcement in October 2025. AES shareholders approved the deal in January with 89 percent support. Regulatory clearance from FERC, the Virginia State Corporation Commission, and Brazilian energy regulator ANEEL arrived between December and February, each with conditions requiring the consortium to maintain current capital expenditure commitments through 2028 and preserve existing supplier contracts.
The deal puts $18 billion in regulated rate-base assets—primarily Indiana Michigan Power and Appalachian Power—under infrastructure fund ownership at a moment when U.S. utilities face $2.1 trillion in grid modernization spending requirements through 2030, according to Edison Electric Institute projections. GIP and its partners acquire AES with $4.7 billion in contracted renewable generation already in place, including the largest battery storage portfolio among independent power producers at 3.2 gigawatts of capacity. The consortium inherits a business mix that is 64 percent regulated utilities, 28 percent renewable contracted generation, and 8 percent merchant power—a profile that offers both stable cash flows and exposure to the energy transition without the activist pressure that pushed AES's public equity volatility above 40 percent annualized in 2024 and 2025.
What allocators should watch: the consortium's refinancing approach when AES's $3.1 billion in senior unsecured notes mature in November 2026 and March 2027. GIP has historically favored asset-level project finance over holding-company debt, and any move to bifurcate the capital structure would signal expectations for regulated utility cash flows to subsidize renewable development rather than the reverse. Separately, the Virginia commission's approval included a review trigger if the consortium sells any AES subsidiary within thirty-six months, creating a Q1 2029 window to watch for portfolio rationalization. The consortium declined to disclose its internal rate-of-return target, though comparable infrastructure fund utility acquisitions have underwritten to 9-11 percent levered returns.
BlackRock Infrastructure, which participated in the consortium but was not the lead investor despite early reporting errors conflating GIP with BlackRock, now controls indirect stakes in utilities serving 4.8 million U.S. customers across seven transactions since 2022—a footprint that approaches 3 percent of the domestic regulated rate base and will draw congressional attention when the Senate Energy Committee reconvenes in April.
