The Environmental Protection Agency’s (EPA’s) release of the Clean Power Plan represents a seminal moment for the power generation industry. Based on statements by President Obama and the EPA, it appears the plan mandates significant but achievable CO2 emissions reductions while giving the states broad discretion in how to achieve those goals. Specifically, the plan provides a framework that will allow states to adopt a market-based approach to achieving reductions, easing the states’ burden while allowing market economics to decide the best mix of generation resources to achieve the goal. Importantly, these emissions reductions will be realized in a manner that ensures continued affordable and reliable electricity. Calpine Corporation (NYSE:CPN) believes the plan, as broadly described, is a workable and achievable approach to control CO2 emissions that will benefit generations to come.

“The Clean Power Plan represents a commitment to continuing the transition from carbon-intensive generation to efficient, low-carbon generation,” said Thad Hill, President and Chief Executive Officer of Calpine. “This flexible, market-based solution will reward the companies that invest and have invested smartly in cleaner generation. We applaud the EPA for its efforts throughout this collaborative process and look forward to working with the agency, states and other stakeholders as the rule is ultimately implemented.”

Calpine believes that a strong commitment to environmentally responsible electrical generation is a key element to achieving our vision of being the premier power generation company in the United States. As the nation’s largest generator utilizing natural gas, our portfolio of assets is well positioned to help achieve these emissions reductions and sustain reliable integration of renewables.

“Given our long-standing advocacy and support for environmental stewardship,” Hill said, “I am happy to say that our modern and efficient fleet of gas fired and renewable generation stands ready to help meet the growing needs of the nation’s electric market in an environmentally responsible way.”
