The current licence from Swiss energy company Repower to use the name expires at the end of 2012, confirmed a Repower Systems spokeswoman. She could not say whether an option exists to further extend the licence.
The rebranding of Repower has been put back on a number of occasions. In June 2010, Repower Systems' then-CEO Per Hornung Pedersen said: "The rebranding must take place before the end of 2012."
In 2011, current CEO Andreas Nauen said the rebrand would take place by the end of 2012.
The simple "renaming" of the company means there will be no change of structure, with the German turbine manufacturer remaining separate from its Indian parent Suzlon.
In the past, the strict separation between the two has been important in Repower Systems' success in getting new finance.
The EUR 750 million in finance facilities running for 2.5 years agreed with three German banks in February 2012 were structured "based on a stand-alone view of Repower."
However, the stand-alone renaming also continues to feed speculation that Suzlon could be considering divesting all or part of Repower Systems.
