The ongoing struggles on the U.S. energy industry claimed another power provider this week as La Paloma Generating Co. LLC, which operators a natural gas-fired power plant in Southern California, filed for bankruptcy Tuesday in Delaware.

La Paloma, owned by Texas-based private equity firm Rockland Capital Energy, listed $524 million in debt in its Chapter 11 petition. The company operates a 1,200-megawatt combined cycle plant 110 miles northwest of Los Angeles in McKittrick, California.
