JRE, which is backed by Goldman’s $3.1bn GS Infrastructure Partners II fund (GSIP), did not disclose the terms of the deal in its online statement on the matter.

It may have paid Summit Wind Power, a unit of conglomerate Sumitomo, as much as ¥3bn ($29.4m), said the Nikkei newspaper, without citing sources.

The project — featuring eight 2MW Vestas turbines — is situated along the Sea of Japan coast in Sakata, Yamagata prefecture.
