Draft rule reduction: 21.3% (419 lbs CO2 / MWh)

Editor's note: The following summary represents state and utility stances after the Supreme Court stayed the Clean Power Plan in February 2016.

Neither a spokesman for Missouri Gov. Jay Nixon (D) nor the Department of Natural Resources responded to questions about how the state will respond to the Supreme Court’s stay of the U.S. EPA Clean Power Plan on Feb. 9.

Missouri lawmakers introduced but did not move forward on legislation that would require the department to cease work until the stay is lifted.

Missouri was among 27 states that filed lawsuits challenging the rule.

Democratic Attorney General Chris Koster has claimed the rule would cost the state's energy producers more than $6 billion. Shortly after the stay, he said Missouri has a competitive advantage in enjoying low energy costs while developing low- and zero-carbon power on "a more reasonable timeline."

“Renewable energy is a vital piece of our state’s energy portfolio,” Koster said in a press release. “It is essential, however, that we achieve this goal in an economically responsible way that makes sense for Missouri.”

Other key Missouri Democrats, including Nixon and Sen. Claire McCaskill (D), have been silent on the Clean Power Plan while Republicans, coal producers and the state's largest utility warned of dire consequences.

Republican Sen. Roy Blunt, who met with members of Missouri electric cooperatives in August, continues to warn that the regulations will boost utility bills and harm middle- and low-income families. St. Louis-based Peabody Energy Corp., the biggest U.S. coal producer, said the plan will "punish" families and businesses with higher energy costs and damage reliability.

The Show-Me State burns coal for more than 80 percent of its electricity, and the state's carbon reduction goal under the final rule is much tougher than in the draft proposal.

Missouri must reduce its power-sector carbon emissions rate to 1,272 pounds of CO2 per megawatt-hour of power produced, much stiffer than the 1,544 pounds CO2/MWh level in the draft rule.

Missouri utilities have already begun retiring some of the state's coal fleet. But Ameren Corp. said the more stringent reductions in the final Clean Power Plan could upset its strategy to transition to cleaner energy sources.

MISO urged to disclose power plant shutdown notices

No matter how the Donald Trump presidency plays out, or whether the Clean Power Plan survives, the Midwest power grid will see dozens of older coal-fired power plants shut down in the next few years. The region's grid operator, the Midcontinent Independent System Operator (MISO), can keep plants running if they are necessary to keep the lights on. But when it comes to knowing which ones will close, and when, will the public be left in the dark?


To cut carbon emissions, some argue for the nuclear option

CALLAWAY COUNTY, Mo. -- The 31-year-old Callaway Energy Center is doing some heavy lifting. Missouri's lone nuclear power plant produces 11.7 percent of the state's electricity from one reactor, making it the third-largest electricity producer in the state. But Callaway really flexes its muscles when it comes to zero-carbon-emissions energy in a coal-heavy portfolio. Missouri gets 82 percent of its electricity from coal.


EPA's final climate rule made compliance easier for some state regulators, harder for others

Whether they plan on embracing or fighting the rule, Virginia, Kansas, Pennsylvania and Missouri are all planning on writing state plans to submit to U.S. EPA proposing how they aim to comply with the Obama administration's recently released Clean Power Plan that seeks to curb greenhouse gas emissions from power plants.


Mo. AG Koster joins states' lawsuit

A frequent critic of U.S. EPA, Missouri Attorney General Chris Koster, said Friday that he is joining a lawsuit against the agency to block it from implementing its landmark Clean Power Plan to cut power-sector carbon dioxide emissions.


Coal-heavy states explore carbon-cutting options with support from National Governors Association

Utah's political leaders are unequivocal about their position on U.S. EPA's Clean Power Plan -- they're not fans. Utah wants to see the proposal retracted or significantly revised. But state officials also don't want to be caught off guard, given the likelihood that some sort of carbon regulation will be enforced in the meantime. That's why Utah and three other states with mixed feelings about the rule have applied for and will receive assistance from the National Governors Association to explore various carbon-reducing options and model how they might affect their electricity systems.


State regulators set sights on Clean Power Plan at winter meetings

It is highly unlikely that there will be a consensus emerging from the upcoming winter meetings of the nation's utility regulators on the merits of U.S. EPA's Clean Power Plan, believed by many to be the most complicated rule the agency has ever issued. But there is optimism that the five-day gathering of more than 1,400 stakeholders starting Saturday in Washington, D.C., might result in a clear-eyed understanding of what it would mean for states to comply -- or not -- should legal challenges fail to upend the proposed rule.


EPA's Clean Power Plan would limit hazardous emissions, too -- report

No matter what effect it has on climate change, a new report says, U.S. EPA's Clean Power Plan will make Americans healthier by curbing their exposure to hazardous emissions. Scientists at Harvard, Syracuse and Boston universities released a report today looking at the potential of EPA's power sector carbon dioxide rule to limit sulfur dioxide, nitrogen oxides and fine particulate matter.


EPA's McCarthy pushes states to adopt carbon-cutting 'investment strategy'

DALLAS -- Gina McCarthy, the administrator of U.S. EPA, appeared at a meeting of state regulators to provide what she called a "signal." "Our energy world is changing, and really the key opportunity here is to embrace a direction that's good and available and reliable and responsible and affordable for each state," McCarthy said, "and to figure out how you can achieve these carbon pollution reductions in a way that's moving in that same direction."
