German asset manager Allianz Global Investors has entered the US wind debt financing market in a big way, providing more than $400m to a 400MW project in Nebraska owned by a unit of billionaire Warren Buffett’s Berkshire Hathaway conglomerate.

BHE Renewables will use the proceeds to reimburse costs of construction for the Grand Prairie wind facility that began in 2015 and will be completed later this month.
