Bigr R posted screen shots apparently showing that he had access to management systems at the , located about 170 miles southeast of Alberquerque New Mexico. Depending on how the software was configured, he could have shut down the 200 megawatt facility or possibly even damaged hardware there, McGrew said.

Florida Power & Light (FPL) owns and operates the Fort Sumner turbines, but the power they generate is used by PNM, an Arizona utility company. The facility has been in use since October 2003.

PNM is not aware of any incidents affecting the company's Fort Sumner facility, said company spokeswoman Susan Sponar. She referred inquiries to FPL. FPL officials were not immediately able to comment on the matter.

The data posted by Bigr R show screenshots of the Wind Turbine's management interface -- Siemens-built software called WinCCC -- along wtih screenshots of an FTP server and a company project management system. There is also Web server header information and configuration data from a Cisco router, apparently hosted for the company by AT&T.

According to the router information, one of the company's passwords for the router was "cisco."
