EPA proposal isn't likely to have much impact on Oklahoma

The Environmental Protection Agency proposed a rule Friday that would limit carbon dioxide emissions from new coal and natural gas electric plants.

New fossil-fueled electric generation plants will have to meet strict emissions standards for carbon dioxide under a proposed rule announced Friday by the Environmental Protection Agency.

The limits on carbon dioxide emissions apply to new coal and natural gas-fired plants. But they will have a greater effect on coal units, which emit almost twice as much carbon dioxide as natural gas units.

The proposed rule is unlikely to affect Oklahoma in the near future, since the state's two largest electric utilities have no current plans to build coal plants. Those plans are in line with the broader utility industry, which is moving toward natural gas for new power plants.

Oklahoma Gas and Electric Co. wants to put off building a new power plant until at least 2020, and has said any new plant would be powered by natural gas. Public Service Co. of Oklahoma plans to phase out its last two coal units in Oklahoma by 2026 and replace the generation with natural gas.

PSO spokesman Stan Whiteford said the utility could be affected by the proposed rule when it decommissions its last coal unit at Northeastern Station near Oologah by 2026.

“These new carbon dioxide limits could very well have an impact on our decision on new generation at that time,” Whiteford said. “Of course, by then, there could be additional advancements in the technology to handle emissions.”

Oklahoma Municipal Power Authority, which plans a new natural gas-fired plant near Ponca City, is studying the EPA's proposed rules, said spokesman Drake Rice. At first glance, it doesn't appear the proposed limits will affect the authority's new natural gas plant, he said. Construction is expected to start in the spring.

Spokesmen for OG&E and PSO said their companies are reviewing the proposed rules for new power plants to see if they might hold clues to another round of regulations by the EPA. The agency is expected to propose rules on carbon dioxide emissions from existing fossil-fueled electric plants by June 2014.

Limits on new plants

The proposed rule on carbon dioxide emissions from new plants calls for limits of between 1,000 and 1,100 pounds of carbon dioxide per megawatt hour of generation. Utilities can choose several options for determining how they will account for the emissions depending on the fuel type.

Power shifting to natural gas, wind, sunshine

— Tough new limits on the amount of heat-trapping emissions new power plants can emit will likely accelerate a shift away from coal-fired power and toward electricity generated with natural gas, wind, and sunshine.

Power prices for homes, businesses and factories may eventually rise, and nuclear power could return to fashion.

The rule proposed by the Obama administration Friday will have little effect on the mix of power sources and electricity prices anytime soon because it only applies to new power plants and is likely to be challenged in court. Even so, market forces are already reshaping power markets in the same way the rule will. A boom in natural gas production in the U.S. has dramatically increased supplies, sent prices plummeting and prompted a shift away from coal.

The rule requires new coal plants to be built with extremely expensive equipment to reduce carbon dioxide emissions. That will make coal look prohibitively expensive to regulators and utilities planning for the future. By comparison, natural gas-fired plants, which emit half as much carbon dioxide as coal plants, along with wind turbines and solar panels, will look like a bargain.

Jason Bordoff, director of Columbia University's Center on Global Energy Policy, called the rule “consistent with already evolving market trends toward the use of natural gas instead of coal” and described it as “cost-effective.”

Nonetheless, it creates financial winners and losers as the energy landscape changes for companies and customers.
