Sandbrook Capital Partners has agreed to acquire United Utility, a US-based power grid operator, in a deal valued at approximately $1bn, marking a major private equity bet on the energy infrastructure sector, according to a report by Bloomberg.
The acquisition positions Sandbrook to capitalise on growing demand for reliable electricity networks and long-term infrastructure investments. United Utility, which manages critical transmission and distribution assets, is expected to benefit from Sandbrook’s operational expertise and capital support to enhance grid efficiency and expand capacity.
The transaction reflects broader private equity interest in utility assets, where stable cash flows, regulatory frameworks, and inflation-linked revenue streams continue to attract institutional investors. Sandbrook intends to maintain United Utility’s existing management team while exploring strategic initiatives to strengthen service delivery and pursue selective expansion opportunities.
Financial terms beyond the headline valuation have not disclosed. The deal is expected to close in early 2026, subject to customary regulatory approvals and closing conditions.
