Environmental Protection Agency

Efficiency Beyond the Low Fruit

Continuous improvement requires changing practices and cultural norms.

As efficiency programs mature, utilities and regulators will be challenged to keep producing demand-side resources. A systems-oriented approach can yield cost-effective results.

Orchestrating Outages

IT systems ease the pain of power plant restarts.

Squeezing plant outage duration by days or even weeks can save the industry billions of dollars in lost running time. The San Onofre outage is just the most visible example of what’s at stake for the industry. New outage management technologies and processes allow generators to coordinate outages and get critical plants back online quickly and efficiently.

Regulatory Gordian Knot

EPA’s new water, waste, and air regulations complicate power plant compliance.

New environmental requirements under the Clean Water Act (CWA) will add to the already complex burden of compliance for power plants. As the Environmental Protection Agency moves forward with cooling water and effluent standards, utilities and generators will have to deal with overlapping rules and conflicting policy goals.

Shale vs. Coal

Portfolio strategies for the new power-fuel market.

Shale gas discoveries and ballooning inventories have pushed natural gas prices down to a 10-year low. At the same time, increasingly stringent emissions regulations are squeezing out some coal-fired power assets. Are we witnessing a power-fuel revolution? And if so, what’s the best survival strategy?

Planning a Fossil Teardown

Decommissioning and remediation of coal- and oil-fired plants.

As new EPA regulations drive companies to decommission older power plants, utilities face issues involving plant retirement and demolition. Some sites can host new power plants, but many can be better used for other commercial purposes. Thoughtful planning and decommissioning strategies can bring the greatest value from underutilized assets.

Green Dealing

Renewable M&A lives on despite death of Treasury cash grants.

The U.S. Treasury cash grants for new renewable power projects expired at the end of 2011. These incentives, which were implemented under Section 1603 of the American Recovery and Reinvestment Act of 2009, helped to support continued capacity additions throughout the recession. The impending expiration of these grants caused a wave of merger and acquisition (M&A) activity during 2011 as developers and financiers rushed to get deals done and to begin construction in order to meet the Section 1603, 5-percent safe harbor threshold by the Dec. 31, 2011 deadline.

Reconsidering Waste-to-Energy

Technology and regulation changes the outlook for garbage burners.

Notwithstanding some past difficulties, trash-fired power plants represent an increasingly attractive opportunity for future clean generation investment. Waste fuel offers a green source of baseload power that’s competitive with fossil fuels. The technology is proven and mature, and it enjoys public policy support. Additionally, waste fuel will help utilities meet diversity goals and environmental mandates.

Regulating Fine Particles

Developing a new paradigm for managing fine particulate air pollution.

The Environmental Protection Agency regulates emissions of particulate matter based on the mass of those emissions—not on the toxicity of the particular components. A growing body of evidence shows that different kinds of particulates affect health differently. Research by the Electric Power Research Institute suggests that in order to most effectively protect public health, the EPA’s next round of air quality standards should differentiate between relatively benign sulfate or nitrate compounds, and more harmful trace metals in particulate emissions.

Baghouse Bottleneck

EPA, mercury and electric reliability.

The energy industry has known for decades that federal regulators eventually would set rules under the Clean Air Act to govern emissions of mercury and other air toxics from coal-fired power plants. However, with the U.S. Environmental Protection Agency now having issued a final mercury rule, along with guidelines for possible extensions of the compliance deadline, utilities and power plant owners finally have a clear idea what they are up against. And the outlook isn't pretty. The challenge is to retrofit many hundreds of generating plants across the country--and all on the same three-year compliance schedule. Yet two wildcards remain in play: what deference the EPA will give to electric reliability needs, as it "consults" with the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Council; and how effective FERC Chairman Jon Wellinghoff will be as Republican leadership in Congress works to derail the new rules.

Partners in Power

Complex problems call for collective measures.

Among all of the investment priorities in the U.S. electric power industry, one stands out as having the greatest momentum: transmission. This is interesting because transmission is perhaps the most difficult type of power infrastructure to develop, and has been for decades. Editor Michael T. Burr talks with executives at Xcel Energy and Great River Energy to learn how the CAPX2020 consortium has managed to succeed where others failed.
