News that global wind turbine giant Siemens Gamesa Renewable Energy (SGRE) is in talks to buy what look to be the main elements of Senvion's assets on sale is obviously good news for the shareholders of the insolvent German OEM, as well as for hundreds of Senvion employees fearing for their jobs.

Majority-owner US private equity firm Centerbridge Partners is likely to get at least part of its investment back.

It is less clear what Siemens Gamesa gets out of a possible deal that may be announced before the end of this month.
