Optimizing Catalyst Performance Lowers O&M Costs

Santee Cooper’s Cross Station has implemented a catalyst optimization program that reduces catalyst replacement cost while maximizing catalyst performance. This case study illustrates the economic advantages of taking a holistic approach to optimizing unit catalyst performance by controlling slag, fouling, sulfur trioxide, and ammonium bisulfate—key factors that lead to premature shortening of catalyst life. With catalyst costing $2 million a layer and up, there is plenty of economic motivation to find ways to improve its life.

Features

Allocating Project Risk

Power generators typically allocate construction risks through the process of aversion. Owners have a tendency to shift risk to a project’s primary contractor, who in turn pushes it to lower-tier parties in the contracting arrangement. Research by the Construction Industry Institute has found that there are more equitable ways to allocate project risk.

Clean Air, Dirty Water

Efforts by power producers to meet clean air rules mean that wastewater effluent streams now face revised EPA regulations. A skirmish involving a New Hampshire power plant could set the tone for the next battle over regulations.

Dusty Trail: The Movie

The season’s blockbuster includes white-hatted heroes, good-natured regulatory sidekicks, bar fights, and a lurking menace named Fugitive Dust.

Fukushima Disaster Continues to Cloud Nuclear Outlook

With new reactors finally under construction, this should be an optimistic time for nuclear power in the U.S. But cheap natural gas, rising construction costs, and the Fukushima accident’s lingering pall have darkened the mood.

Gas Glut Drives Action in Combined Cycle Power

A diverse range of speakers reviewed the state of gas-fired generation at ELECTRIC POWER, but there was one constant: flexibility

Innovation Required as Gas Displaces Coal

Panelists at the ELECTRIC POWER Keynote and Roundtable Discussion in Baltimore in May wrestled with a range of issues. But despite calls for a “balanced portfolio,” an “all-of-the-above” energy strategy, and predictions of “more changes in the next 10 years than in the last 100,” the focus of attention appears to be the decidedly mundane displacement of coal by natural gas.

New Technologies Advance Biomass for Power Generation

As U.S. utilities seek to increase the percentage of carbon-neutral biomass used in their generation portfolios, they must deal with a number of complex challenges unique to this fuel source. Several breakthrough technologies are poised to help promote greater use of biomaterials.

Performance-Based Cooling Water Treatment

A West Coast combined cycle plant that uses reclaimed water found that cycling 300 times a year caused disruptions to the plant’s cooling water chemical treatment program. The solution was a performance-based monitoring and control system that uses available plant operating data plus algorithms to measure corrosion rates and fouling factors, which in turn allows the plant to trim chemical feed rates so they correlate with a specified corrosion rate, rather than a suggested chemical residual.

Power in India: Opportunities and Challenges in a Fast-Growing Market

India’s long-term annual economic growth rate is projected at over 7%, and the country is investing in its hydroelectric, nuclear, and renewable resources. However, the primary fuel used to produce electricity remains coal, and the government has ambitious plans to significantly increase coal-fired capacity. Those plans have been challenged by a number of unexpected factors that threaten to stifle India’s economic growth.

Utility Perspectives on Ramping Up Renewable Power

Panelists at ELECTRIC POWER discussed how U.S. utilities choose renewable power generation technologies based on their geographic locations, state requirements, economics, and other criteria—including reliability and federal regulations.

Incentives Provide Boon to Hydropower Industry

The U.S. hydropower industry has undergone a renaissance in recent years. One of the major drivers of the industry’s growth, the establishment of the production tax credit (PTC) for hydro, has seen strong policy support from our elected officials in Washington, D.C. More than any other federal policy, tax incentives, particularly the PTC, have sparked a level of growth in the industry not seen in nearly two decades.

When Successful Procurement Policies Fail

California is approaching a tipping point with respect to the near-term economic viability of existing non-utility generation. The procurement policies and practices implemented in response to the statewide energy crisis over a decade ago have evolved into market conditions that do not offer “uncontracted” existing resources with sufficient and stable enough revenue streams to recover going-forward costs. Continued adherence to these policies will subject such resources to an increasing risk of economic retirement, threatening long-term reliability and potentially costing electric consumers billions of dollars.

FERC Rule 1000: What Does It Mean?

The Federal Energy Regulatory Commission (FERC) has the responsibility for ensuring just and reasonable rates and preventing undue discrimination by public utility transmission providers. Last year FERC defined a new framework for public utilities and regional transmission organizations planning new transmission networks. The framework is provided in Order No. 1000—Transmission Planning and Allocation by Transmission Owning and Operating Public Utilities. The Final Rule was issued on July 21, 2011, and reaffirmed by Order No. 1000-A on May 17, 2012.


Improving Slurry Knife Gate Valves in FGD Applications

The primary considerations in slurry valve selection are reliability in function and design, abrasion resistance, and ease of maintenance. In addition, valves with a straight-through, unobstructed flow minimize the effect of abrasion and therefore reduce the need for maintenance.


Safety Implications of Coal and Biomass Fuel Mixes

Practically everyone would agree that the energy policy of the U.S. is in a great state of flux. Not since the introduction of commercial nuclear power some five decades ago has our country come to such an energy crossroads. No matter what your political ideology, no one can refute that conventional coal-fired power plants are being paralyzed by recent and potential U.S. Environmental Protection Agency (EPA) regulations designed to cut the nation’s reliance on coal.

MACT Attack

The Utility MACT Rule, the most recent skirmish in the U.S. Environmental Protection Agency’s (EPA’s) war on coal, is based on flimsy scientific evidence of actual health effects and again demonstrates the agency’s indifference to conducting rigorous scientific inquiry. The end justifies the means is not science.
