Longview Power LLC, a 700-megawatt coal-fired power plant in West Virginia, is seeking an extension of its sole right to file a bankruptcy exit plan as it continues to spar with contractors over who's to blame for the operational problems that have dogged the $2 billion facility, the Wall Street Journal reported today. Longview's exclusivity period is set to expire on Feb. 26 and the company is asking Bankruptcy Judge Brendan Shannon to extend that period to March 14.
