In yet another black eye for the long-delayed and hugely over-budget Kemper County integrated gasification combined cycle plant (IGCC), the Mississippi Supreme Court ruled on Feb. 12 that the Mississippi Public Service Commission (MPSC) erred in granting plant owner Mississippi Power rate increases in 2013 and 2014, and ordered that the increases be refunded to […]

PPL Montana, a subsidiary of PPL Corp., announced on Feb. 10 that it will permanently shut down its J.E. Corette coal-fired power plant located near Billings. The 153-MW plant began operation in 1968. In 2012, the company decided to mothball the plant, retaining the option to restart it if wholesale power market conditions in the […]

The sixth annual ARPA-E Summit wrapped up on Wednesday, and though there were too many sessions to cover in depth, here is a mini-summary by way of selected interesting comments. Speaker photos (where available) follow the comment. “Any disruptive technology will not fit an existing market.” —Brian Janous, Director of Energy Strategy, Microsoft “[The energy […]

“The coolest thing on Earth” is, according to its new director, a young federal agency that has a unique focus on pushing technology frontiers and an “unblinking attention” to market realities. One thing you can say for sure about the energy world, said Dr. Ellen Williams (Figure 1), incoming director of ARPA-E (Advanced Research Projects […]

According to Peter S. Glaser, partner with Troutman Sanders LLP, who practices in the energy and environmental law fields, saying “no” is an option that states have in response to the Environmental Protection Agency’s (EPA’s) Clean Power Plan proposal. Speaking during a panel discussion at George Mason University’s Law and Economics Center on Feb. 4, […]

The Byron Sher Auditorium in Sacramento, Calif., was filled at times with students, parents, and other concerned citizens as the Environmental Protection Agency (EPA) held the last of three public hearings on proposed updates to the national air quality standards for ground-level ozone on Feb. 2. The hearings were scheduled as part of the policymaking […]

The Department of Energy (DOE) announced on Feb. 3 that it was ending its involvement with the troubled FutureGen 2.0 clean coal project, concluding that it had run out of time to finish development before federal funding expires in September. First proposed under the Bush administration in 2003, suspended in 2008, then revived and allocated […]

An unnamed power company and the U.S. Naval Research Laboratory (NRL) have partnered to test a concept proven to work at a small scale that applies pulsed electron beam technology to slash coal plant nitric oxide and nitrogen dioxide (NOx) emissions. The concept (Figure 3) essentially involves directing electron beams from a cathode into the […]

Despite its efficiency and environmental benefits, combined heat and power (CHP) generation has languished at around 10% of worldwide capacity for more than a decade. But a global review shows growth in some sectors and promising new technology on the way. The statistics are both eye-opening and somewhat depressing. Globally, according to the International Energy […]

As it struggles to grow its economy while improving air quality in urban areas, China is updating its energy delivery infrastructure. A key part of that plan is switching from coal-fired to gas-fired combined heat and power plants. To push efficiency even further, some plants are turning to synchronous clutches. The developed world has done […]

American Electric Power, one of the premier generating utilities in the U.S., is caught between a deregulated rock—wholesale competitive capacity markets that don’t, in the company’s opinion, value solid equipment over ephemeral demand response—and a regulatory hard place of increasing federal government rules that devalue on-the-ground coal-fired generation. Add the competitive challenge of cheap natural […]

An increasing supply of low-cost higher-chlorine coal is prompting many U.S. generators to give the fuel serious consideration in spite of its reputation for causing corrosion. Though corrosion can be a consideration, it’s not always caused simply by the fuel switch. Understanding the various chemical interactions, as well as operational and emissions pros and cons, […]

Proposed U.S. standards for reducing carbon emissions from existing coal-fired power plants rely heavily upon generation-side efficiency improvements. Fuel, operations, and plant design all affect the overall efficiency of a plant, as well as its carbon emissions. This review of the fundamentals of coal plant efficiency, frequent problems that reduce efficiency, and some solutions for […]

According to a study funded in part by the U.S. Department of Energy (DOE) and conducted by Massachusetts Institute of Technology (MIT) researchers, a smaller portion of carbon dioxide (CO2) that is injected into the ground may be converted into rock than was previously presumed. The team, working in the Department of Earth, Atmospheric and […]

In a dramatic move that passed the state Legislature with little debate and almost no opposition, West Virginia lawmakers on Jan. 22 voted to repeal the state’s 2009 alternative energy standard, which requires utilities to get 25% of their power from alternative sources by 2025. The repeal bill passed the state Senate unanimously and the […]

On Jan. 14, the Environmental Protection Agency (EPA) published its Toxics Release Inventory (TRI) report for 2013 showing that electric utilities have cut toxic releases to the environment 49% since 2003. The drop was driven by a 73% decline in on-site toxic air releases as a result of a decrease in hazardous air pollutants (HAP) […]

Michigan Gov. Rick Snyder announced a series of deals designed to eliminate a costly utility rate payment in the state’s Upper Peninsula (UP), while providing long-term, cost-effective energy reliability for the region. The solution was developed through four principle agreements. In one, the electric utility businesses now owned by We Energies and Integrys (doing business […]

Düsseldorf, Germany–based energy supplier E.ON announced on Jan. 12 that it would sell its Italian coal and gas generation assets to Energetický a Průmyslový Holding (EPH), a Czech energy company. E.ON has been looking for a suitor for the Italian operations since at least Nov. 30 when it announced it was embarking on a new […]

According to a story first reported by Amanda Levin of TheStreet.com, American Electric Power Co. (AEP) has retained the services of Goldman, Sachs & Co. in an effort to unload its 7,923-MW merchant generation fleet. AEP—headquartered in Columbus, Ohio—is one of the largest electric utilities in the U.S., serving over five million customers in 11 […]

The U.S. Environmental Protection Agency (EPA) said today that a delay in issuing final rules affecting carbon dioxide emissions from new power plants, which were due this week, will help the agency release a set of more coordinated rules covering new, existing, and modified plants. The carbon dioxide rule for new plants—issued under Section 111(b) […]

The trial operation of a steam loop for more than 17,000 hours at temperatures exceeding 760C (1,400F)—the highest ever tested at a pulverized coal plant—have wrapped up at Plant Barry Unit 4 in Alabama

Renewables’ share of the global power mix is slated to overtake coal to become the largest source of electricity by 2040, the International Energy Agency (IEA) projects in its 2014 edition of the World
