Houston-based Dynergy has backed out of a joint venture with LS Power Associates, which would have developed new coal-fired power plant projects. The reasons Dynergy cited for pulling out of the venture were the current credit market and the multiple regulatory hurdles that they would face. As part of the split, Dynergy will retain its rights to approximately 30 projects and pay LS Power Associates $19 million, and LS Power Associates will transfer to Dynergy the rights to projects in Arkansas, Georgia, Iowa, Michigan, and Nevada.
