On August 10, the American Clean Skies Foundation released Repurposing Legacy Power Plants: Lessons for the Future arguing that coal-fired power plants set to close in the coming decade present “tremendous” redevelopment opportunities like riverfront housing, shops, offices, museums, and parks. Industry analysts predict that 15-20% of US coal plants might retire by 2020 due to age, EPA toxic emissions rules, and natural gas competition. The report says at least 20 of the dozens of plants may be good candidates for redevelopment, and this kind of redevelopment frequently takes several years due to potentially huge upfront costs, cleanup, working with old buildings, meeting requirements for historic preservation, and special financing challenges.
