PNE Wind UK's 1.2GW pipeline and employees have also been transferred to the new owner. PNE said it had invested approximately £27 million in to the pipeline to date. It does not own any operational projects.

PNE said during the negotiations it "became clear that investors were interested in acquiring the shares".

According to the PNE Wind UK website, the pipeline is mostly situated in Scotland and northern England.
The asset management firm has a large portfolio of renewable energy assets. In March 2014, Brookfield agreed to acquire the 500MW portfolio or Irish utility Bord Gais.
