On Monday General Electric Co disclosed that the industrial conglomerate was being investigated by the European Union’s competition watchdog. The investigative body is reviewing allegations that GE provided misleading information during a merger review with LM Wind Power which took place last month. At the time of the merger the transaction seemed to have the approval of the US, the EC, China, and Brazil.

However, according to a statement provided by GE, on March 9 2017, the corporate giant was provided with a notification by the European Commission that it was opening a proceeding to evaluate possible infringements in the transaction. GE said it is cooperating with the investigation and since that time, no formal information has been provided.

Last October, GE announced its intention to purchase a Danish producer of wind turbine blades, LM Wind Power, for $1.65 billion from the private equity firm Doughty Hanson. The motivation behind this transaction is of course to enable GE to secure a larger portion of the lucrative renewable energy market. As of March the EU had approved the deal.

However, this approval was given after GE assured EU regulators that it no plans to develop a giant new offshore wind turbine. According to Bloomberg news, which was the first to report upon the these events, it was shortly after the company had received approval that the EU began to suspect it had been mislead. Two years ago in a $10 billion deal GE took over Alstom SA’s power operations. This included the Alstrom Renewable Power Sector which was renamed GE Renewable Energy and currently produces 6 megawatt offshore wind turbines.

If the probe decides there was intentional deception on the part of GE, the next step in the procedure which could take months, would be the filing of what is described as a statement of objections. As punishment, GE could face a penalty of up to 1% of its annual sales.
