NeXtWind’s shareholders are mooted to be preparing a sale of the business.

Sandbrook Capital, Public Sector Pension Investment Board and the Investment Management Corporation of Ontario (IMCO) acquired NeXtWind Capital from a Crestline Investors-led shareholder group in summer 2023.

The company now operates 37 onshore wind sites with 500 MW of installed capacity as of late 2025, with 1.9 GW in permitting and construction. The company aims to exceed 3 GW of capacity by 2028.

Sandbrook for one, which holds a majority stake in the company, is now believed to be lining up the sale of its holding, according to three market sources, with the process envisaged to launch either later in 2026 or by the start of 2027.

The group’s backers are believed to have mandated financial advisor UBS to support in the future sale.NextWind completed a EUR 1.8bn syndicated debt financing in November 2025, with proceeds to be used for acquisitions, repowering of existing wind parks, and development of integrated clean energy hubs.

The Berlin-based IPP launched in late 2020 with a focus on acquiring and rejuvenating older onshore wind farms across Germany which have typically been in operation for over 10 years.

Sandbrook, PSP and IMCO said three years ago that they aimed to commit up to USD 750m in equity to support NextWind Capital’s growth over the coming years.

None of Sandbrook, NextWind or IMCO responded to a request for comment. PSP Investments declined to comment.
