Coal

A much greater coal power burn is expected this summer in reaction to an anticipated rebound in natural gas prices, suggests a recent reliability assessment from staff at the Federal Energy Regulatory Commission (FERC). Among other key aspects of the new report is that while electric reliability for the rest of the nation will be adequate, Texas could see a significant chance of an energy emergency.

A new version of coal ash legislation introduced in the U.S. House of Representatives on Monday sets minimum federal standards for coal residuals from coal-fired power plants, but it gives states—not the Environmental Protection Agency (EPA)—responsibility for crafting their own permit programs.

In a report released on May 13, the U.S. Energy Information Administration (EIA) presents data on energy-related carbon dioxide (CO2) emissions for each state by year, fuel, sector, and other breakouts for the years 2000 through 2010.

AES Corp.’s subsidiary Dayton Power & Light (DP&L) plans to retire six coal-fired units representing about 390 MW at its 414-MW Hutchings coal-, gas-, and oil-fired plant in Miamisburg, Ohio, by June 2015 as a result of existing and expected environmental regulations, including the Mercury and Air Toxics Standards (MATS). The news comes on the heels of Indianapolis Power & Light Co.’s (IPL’s) announcement that it plans to retire 600 MW of coal-fired capacity to comply with environmental rules.

Cost overruns of nearly $1 billion to build the 582-MW Kemper integrated gasification combined cycle (IGCC) plant in Kemper County, Miss., were underscored on May 20 as Mississippi Power’s Board of Directors took the dramatic step of replacing the Southern Co. subsidiary’s leadership.

Operators familiar with the unique requirements of burning Powder River Basin (PRB) coal will tell you that it’s not a case of “if” you will have a PRB coal fire, it’s “when.”

Every piece of equipment that transports or processes coal creates some level of particulate matter. Having a strategy for coal dust management in your plant is essential.

Electric motors are the largest energy consumer within a typical industrial plant. Motors also present the greatest opportunity to reduce auxiliary loads, particularly those with high usage factors.

Investments into Australia’s power sector enable the industry to meet the collective goal of becoming a cleaner, greener nation. Download the report.

Los Angeles sits alongside the world’s largest body of water, and naturally the city’s Department of Water & Power (LADWP) placed its generating stations along the shoreline to take advantage of that abundant resource for cooling. The LADWP built three coastal generating stations that provide the city with 2,162 MW, about 35% of the peak annual demand.

The D.C. Circuit Court on Tuesday dismissed an appeal by Sunflower Electric Power Corp. of a ruling requiring environmental review of Sunflower’s proposed 875-MW coal-fired power plant in Holcomb, Kansas.

A carbon tax or cap-and-trade programs could raise trillions of dollars within the first 10 years of their enactment and avert climate change effects, but without accounting for how these revenues will be used, they could take a toll on the U.S. economy, the Congressional Budget Office (CBO) says in a report released on Tuesday.

Cost overruns of nearly $1 billion to build the 582-MW Kemper integrated gasification combined cycle (IGCC) plant in Kemper County, Miss., were underscored on Monday as Mississippi Power’s Board of Directors took the dramatic step of replacing the Southern Co. subsidiary’s leadership.

Domestic content requirements that require some generators to source up to 60% of equipment from the Canadian province of Ontario under its feed-in-tariff (FIT) program are inconsistent with international trade rules, officials from the World Trade Organization’s (WTO’s) highest court said on Monday.

Panelists at a House hearing today refuted varied claims concerning if and how increased natural gas and renewables generation pose widespread challenges to the reliability of the electric grid. Some pointed to ineffective rules in the restructured wholesale power market and the failure of conventional power plants as being more of a threat to grid reliability.

Last year’s stampede toward gas in the power sector is moderating for 2013, as higher gas prices cut into the economic incentives supporting coal-to-gas switching.

Navajo Nation President Ben Shelly signed a land lease extension on April 30 for the 2,250-MW Navajo Generating Station, but not before adding several amendments to the agreement. The early lease renewal with the Navajo Nation must be in place before plant owners could consider making future investment in expensive new air quality control equipment.

Drought is a serious vulnerability for the power sector, witnesses testified at a full committee hearing held last week in the Senate to assess the impacts of drought on the power and water sectors. Members of the panel invited by the Senate Committee on Energy and Natural Resources offered a number of possible solutions for federal agencies and power companies that could mitigate adverse effects from drought.

Germany has chosen to transform its energy system within a few decades—an ambition that has evoked equal admiration and confusion. Has Europe’s largest economy embarked on a rational path to an energy future that will make it the bellwether for global acceptance of renewables, or will the complex array of current challenges encumber its grand transformation?

China has gone through three periods of nationwide power shortages since 1978. The previous two shortages were mostly caused by the lack of installed generation capacity. However, the third—which has severely restricted economic development—is a consequence of institutional problems that must be corrected.

The number of regulated air emission constituents is increasing while the acceptable amounts for release are decreasing. In the long run, picking the most flexible multipollutant technology is surely the least cost option.

India’s Reliance Power in March synchronized the first of six 660-MW units of its Sasan Ultra Mega Power Plant (UMPP) in the state of Madhya Pradesh, readying it to supply power to 14 distribution companies across seven states. The plant (Figure 1) has been hailed as India’s first supercritical project to integrate a coal mine—an important achievement in a country that is battling chronic coal shortages. Though India has large coal reserves, domestic mining companies are struggling to keep up with demand needed to sustain its existing coal plants, which account for 55% of its generation.

My career began as a results engineer testing large utility boilers. Ever since that first assignment, I have remained interested in the details of how the measurement and control of the furnace fuel and air inputs can make a huge difference in overall boiler performance. Given that plant operations and maintenance (O&M) budgets are slimmer today than in recent memory, my experience is that targeted performance testing can provide important feedback for prioritizing maintenance expenditures. The combination of plant testing and targeted O&M expenditures provide the best opportunity for efficient and reliable plant operations. I call this approach to plant efficiency improvement “performance-driven maintenace.”

By the end of 2013, one year ahead of its goal, the province of Ontario will be virtually coal-free—a first for a North American jurisdiction. How did the most populous part of Canada go from 25% to 0% coal-fired generation in just a decade, and what does this phaseout mean for the rest of the world?

A settlement between the federal government, the Sierra Club, and Wisconsin Power and Light Co. (WPL) on Monday could require the Madison-based Alliant Energy subsidiary and other defendants to invest more than $1 billion in pollution controls and retire and refuel at least four units at three Wisconsin coal-fired power plants to resolve alleged Clean Air Act New Source Review violations.

Revisions proposed on Friday by the Environmental Protection Agency (EPA) to technology-based effluent limitations guidelines and standards could set the first federal limits on the levels of toxic metals in wastewater discharges from steam electric power plants. The proposed rule would help reduce pollutants in U.S. waterways from coal ash, air pollution control waste, and other power plant waste, but they could come at a cost of between $185.2 million to nearly $1 billion a year, the agency said.
