There is 1,800 capacity in Wuxi, so I think 1.2GW will be sold off,
"The first of those three subsidiaries is cell manufacturer Luoyang Suntech, holding 200MW of cell capacity and considered to have the most expensive and the oldest cell production lines. The second is Shanghai Suntech, apparently reminiscent of the thin-film production facilities as suggested by Solarzoom, but according to 20-F filing 2011 Annual Report, this location also holds 400MW of cell and module production lines with the company’s high-end efficiency product, the “Pluto” module. Finally, the third subsidiary is a facility manufacturing solar ingots and wafers; however, there is no clarity whether both Zhenjiang Rietech and Zhenjiang Rende New Energy Science Technology Co., or just one of them, will be allowed to go bankrupt. Suntech’s total wafer capacity was quoted by the company recently as 1.65GW."
No word on those other plants being shut down, but they were suggested to go first as being old and expensive.
That 600MW is only 40% owned by Suntech Wuxi and rest by Wuxi Industrial Development Group and Wuxi New District E&D Group.
The way this is going it looks to me that they are selling off the assets to pay creditors and will keep 40% of Suntech's owned asset for themselves (Wuxi will) I think that means that wafer factories as well Shanghai and Luoyang will be sold off as well. Shanghai has Pluto.
