Sept 16 (Reuters) - RWE RWEG.DE, Germany's biggest power producer, said on Wednesday it had bought an additional 3% stake in M31, which holds around three-quarters of shares in transmission system operator Amprion.
With the acquisition, RWE's pro-rata stake in Amprion will increase to about 58%, making it the majority shareholder of M31, RWE said. 

Here are more details:
RWE said Amprion will remain an independent transmission operator, adding that it will consolidate its stake in Amprion at equity. 
Sources told Reuters earlier this year that Amprion's major owners were considering selling their stakes to new investors.
In July, Germany's Federal Cartel Office approved RWE's acquisition of about 47% of shares in M31.
M31's shareholders include MEAG Munich Ergo, which is Munich Re's MUVGn.DE asset management arm, along with Swiss Life SLHN.S, Talanx TLXGn.DE, insurer Versicherungskammer and Commerzbank's CBKG.DE Commerz Real.
