For the year, GE's renewable energy unit recorded a loss of $666 million, down from a $292 million profit across 2018.
In Q4, the unit posted a loss of $197 million, having recorded similar shortfalls of $162 million, $184 million and $98 million across the first three quarters of the year, respectively.
"Segment profit of negative $197 million was driven by execution issues, particularly in grids; price headwinds; tariffs; and increased R&D investment," the US conglomerate explained in its report.
However, revenue and the order total was up in the Renewable Energy unit. Revenue for the year was $15.3 billion, up 7%.
Meanwhile orders grew 10% to $16.9 billion for 2019, despite a slight dip in Q4 which was 11% lower than the same period in 2018.
The manufacturer added it had received 1.2GW of new onshore wind orders from China in 2019 — a typically difficult market for western OEMs to do business in.
