The increasing cost of natural gas relative to coal is expected to increase coal’s share of total generation from 37.4% in 2012 to 39.9% in 2013, according to the U.S. Energy Information Administration (EIA) April release of its Short-Term Energy Outlook (STEO). Though that would leave coal’s percentage below its 42.3% share in 2011, it indicates that gas may not be on an inevitable path to overtake a significantly greater share of the generation pie.

The United Arab Emirates (UAE) is made up of seven emirates, yet two dominate the demographic, economic, and geopolitical landscape. Download the report.

Several European governments have so far this year bucked a reluctance to extract shale gas via hydraulic fracking even as the practice continues to be strongly opposed in countries like France and Bulgaria.

On the second anniversary of the 9.0-magnitude Great Tohuku Earthquake that killed more than 25,000 people and set off the worst nuclear disaster in 25 years, Tokyo Electric Power Co.’s (TEPCO’s) devastated Fukushima Daiichi Units 1 through 4 were in cold shutdown and set to be abolished. All Japan’s nuclear reactors remain shuttered for safety inspections, and the rattled nation has yet to finalize a future energy roadmap. Meanwhile, as panelists at the IHS CERAWeek noted, the world’s global nuclear sector seems to have made a slow but determined recovery.

The Environmental Protection Agency (EPA) estimates final regulations curbing greenhouse gas (GHG), mercury, and air toxics emissions from new sources could appear in the Federal Register over the next six weeks. Also forthcoming are final cooling water intake rules and proposed effluent guidelines. The coal ash rule, which has no target date for a final rule, may not be issued this year, the agency said.

Energy demand in Mexico, according to the Secretary of Energy (SENER), will increase by approximately 4% each year for the next ten years, and with it the potential for private sector growth in the industry. Download the report.

Controversy concerning natural gas exports flared the day the U.S. Energy Information Administration (EIA) released its estimate that U.S. natural gas exports could begin in 2021.

Here are some of the longest pipelines recently built as well as noteworthy ones in the pipeline.

More and more electricity is generated by natural gas. This trend is likely to persist. Hydraulic fracturing technology is increasing domestic supplies and enabling natural gas prices to remain at historic lows.

The lifeblood of the combined cycle plant is its water chemistry program. This is particularly true for plants designed for high pressures and temperatures as well as fast starts and cycling. Even though such plants are increasingly common, no universal chemistry program can be used for all of them.

Steam turbine blade cracking often suggests the need for an upgraded blade design. Follow the process of reversing engineering a failed blade to produce a more reliable and efficient design.

Most professionals in the energy industry know about biomass; fewer of us are conversant with biogas. This commentary explains the basics of biogas, with a focus on its current use and future potential as a source of electrical power.

Japan’s scramble to replace generation lost from nuclear power plants that were shuttered after the March 2011 Fukushima Daiichi nuclear accident has forced it to rely on pricey imports of fossil fuels—and soaring energy costs are hammering the world’s third-largest economy.

A rule proposed by the Environmental Protection Agency (EPA) directs 36 states to revise their Clean Air Act State Implementation Plans (SIPs) to eliminate exemptions for excess emissions of air pollutants at power plants during startup, shutdown, or when the plant malfunctions.

Boosted by President Obama’s inaugural address commitment to mitigate climate change, congressional Democrats have initiated several more climate measures. A legislative packet that seeks to mitigate climate change by enacting a carbon "fee" of $20 per ton of emitted carbon or methane equivalent was introduced last week by Sens. Bernie Sanders (I-Vt.) and Barbara Boxer (D-Calif.). In the House, as several Democratic amendments for climate change hearings were voted down, more than 40 lawmakers urged President Obama to create a panel that would help communities deal with climate change events.

President Obama outlined a number of key energy-related measures in his State of the Union speech on Tuesday night, urging Congress to pursue legislation to mitigate climate change and calling for an expansion of clean energy and reduced red-tape for natural gas and oil permits.

A newly announced resource strategy could require Duluth, Minn.–based Minnesota Power to convert its 110-MW Laskin Energy Center in Hoyt Lakes, Minn., to a natural gas peaking facility in 2015, install environmental upgrades at its 558-MW Clay Boswell Energy Center Unit 4 in Itasca County, and retire one of three coal-fired units at its 225-MW Taconite Harbor facility in Schroeder.

Citing low natural gas prices, Duke Energy announced on Feb. 1 that it would shutter its 1920s-built Buck and Riverbend stations two years before the coal-fired plants were slated for retirement. The company had chosen to retire the plants just before April 2015, which is the compliance deadline for recently enacted federal environmental rules.

Improper layup practices are a major contributor to boiler tube failures and to steam turbine pitting and cracking in U.S. fossil plants. EPRI’s research into identifying damage mechanisms, utility best practices, and innovative new methods to protect plant equipment during outages will aid plant operators in achieving a successful layup.

The electricity industry is being transformed by the so-called “shale gas revolution” in the United States. Production of natural gas from shale rock using hydraulic fracturing (“fracking”) has boosted supply and reduced prices, making gas-fired power competitive with coal-fired power on price. Historically, coal-fired electricity generation has dwarfed generation from gas-fired plants in the U.S. […]

Average spot natural gas prices in New England have surged to $3 per million British thermal units (MMBtu) higher than natural gas prices at the Henry Hub since November, driven up by supply constraints from natural gas pipelines that haven’t kept up with demand, high international prices, and declining production in eastern Canada, the U.S. Energy Information Administration (EIA) says in a report released last week.

Wisconsin Energy nearly doubled its natural gas burn for power generation in 2012, from 23.9 billion cubic feet (bcf) in 2011 to 46.5 bcf in 2012. Gale Klappa, CEO, said during a January 30 earnings conference call that natural gas units at the company’s 1,150-MW Port Washington generating station operated at a 46% capacity factor in 2012. This compares with a 23% capacity factor in 2011.

A federal appeals court last week denied a motion from developers of new coal- and oil-fired power plants to force the Environmental Protection Agency (EPA) to finalize its reconsidered Mercury and Air Toxics Standards (MATS) for new sources by March and help them avoid a regulatory Catch-22 posed by a looming rule to curb greenhouse gas emissions in new plants.

Georgia Power on Monday said it was seeking state regulatory permission to decertify and retire 15 coal- and oil-fired generating units—a total capacity of 2,061 MW—citing several factors, including costs to comply with existing and future environmental regulations, economic conditions, and lower natural gas prices.

The Environmental Protection Agency (EPA) on Dec. 20 finalized changes to a specific set of adjustments to Clean Air Act that apply to a coal, oil, natural gas and biomass boilers and certain solid waste incinerators.

Global generating capacity is poised to soar by more than 72%, to 9,340 GW, by 2035 from 5,429 GW in 2011, despite retirement of about 1,980 GW, the International Energy Agency (IEA) forecasts in its World Energy Outlook 2012, released in November.

Achieving a balance between affordable and sustainable electricity while improving reliability is a challenge unlike any the electricity sector has faced since its inception. Technology innovations in key areas such as energy efficiency, smart grid, renewable energy resources, hardened transmission systems, and long-term operation of the existing nuclear and fossil fleets are essential to shaping the future of electricity supplies.

North American shale gas was supposed to realign the generation fleet here and abroad (thanks to anticipated exports) far into the future. Turns out, that’s not exactly how the near term is shaping up. Despite stagnant (and even putrid) economies and legislative bodies in the U.S. and EU, there promises to be sufficient market volatility to keep everyone alert.

For the first time, U.S. generation from coal and natural gas was equal in 2012, although just momentarily. Gas dominated early in the year, but as gas prices rose in response to supply and demand forces, coal use rebounded. Expect more of the same give-and-take in 2013.

The availability and low price of natural gas enticed many U.S. utilities to fuel switch on a grand scale in 2012. Increased demand has put upward pressure on prices, moving coal back to the top of the dispatch order in some regions. Expect the price momentum to shift often in 2013.
