Low natural gas prices and static coal prices have created a business opportunity for power producers to utilize significantly greater amounts of natural gas to meet their generation demand. In addition, increasingly stringent environmental regulations will require many coal-fired units to be retired or to be retrofit with emissions control equipment for continued operation on coal.
