Tubular Turbine Hydropower Plant Comes Online
Albania this June inaugurated its first major hydropower project since the early 1980s, bringing online Ashta I, the first of two run-of-river plants with a combined capacity of 53 MW. At the inauguration ceremony, Albania’s Prime Minister Sali Berisha called the plant “a novelty” because it is the largest in the world to use advanced tubular turbines technology.

Flow Control Chutes Reduce Fugitive Coal Dust
Moving thousands of tons of coal per hour at high speeds through a complex handling system is a main cause of airborne coal dust in a coal-fired plant. Depending upon the coal’s characteristics, that dust can become explosive when its concentration reaches 80 g/m3 and, hence, a threat to life and property. The best option is to stop the dust from becoming airborne in the first place.

New Gas-Fired Technology Gains Backers
A new gas-fired power generation technology that uses an oxyfuel, high-pressure, supercritical carbon dioxide cycle and produces pipeline-ready carbon dioxide for sequestration or use in enhanced oil recovery (EOR), without reducing plant efficiency, garnered the interest of three new partners in June.

New Environmental Rules Keep Pressure on Coal-Fired Generation
New U.S. Environmental Protection Agency regulations affecting the nation’s coal power plants are routinely in the national news. The latest proposed rule focuses on the release of carbon dioxide into the atmosphere. With a substantial amount of coal generation expected to be shut down (up to 40 GW to 50 GW in the coming years by some accounts), the new regulations are increasing the likelihood that this lost capacity will not be replaced by new coal generation.

Too Dumb to Meter, Part 3
As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the third chapter, “Micro-Mismanagement by Committee.” During the frenzy to manage atomic power after World War II, Congress created an executive branch agency that threatened to be too independent, too powerful, and too isolated from the rest of government. Compounding their errors, perhaps in recognition of what they had created, the solons also developed a way to insert their own power into the action. This proved to be a major mistake—blurring the lines between executive and legislative authority—causing no end of problems for the nation’s nascent atomic energy venture.

Consent Decree Could Force Closure of FirstEnergy Coal Ash Impoundment Facility in Penn.
A lawsuit filed in federal court on Friday by Pennsylvania’s Department of Environment Protection (PDEP) alleges that FirstEnergy’s Little Blue Run Dam coal ash impoundment pond in Beaver County, a facility that stores coal ash from the generator’s 2,470-MW Bruce Mansfield coal-fired power plant in Shippingport, Pa., has leached heavy metals in drinking water supplies and surface water. A proposed consent decree could force the generator to shut down the impoundment facility.

Leveraged with recipient cost-sharing to support about $9.4 million in total projects, the awards are expected to support the development and deployment of “carbon capture, utilization, and storage (CCUS)” by focusing on further improving the efficiency and reducing the costs associated with carbon capture.

Federal Court Rejects Challenges to EPA Industrial, Automotive GHG Rules
A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on June 26 ruled that the U.S. Environmental Protection Agency (EPA) was "unambiguously correct" in its interpretation of the Clean Air Act (CAA) to regulate carbon dioxide emissions. The federal agency’s endangerment finding that greenhouse gases (GHG), including carbon dioxide, are a threat to public health and welfare, and its decision to set limits for industrial and automotive emissions of GHGs, was "neither arbitrary nor capricious," the court ruled. The court, however, found that it lacked jurisdiction to review the timing and scope of the GHG rules that affect larger stationary sources, including new coal-fired power plants.

Coal Could Regain Ground from Gas as Summer Demand Ramps Up
Natural gas-fired generation enjoyed a competitive advantage through this past winter and spring as historically low prices for the commodity combined with mild weather and relatively light demand to turn the dispatch stack on its head and favor gas over coal. That advantage is narrowing as summer demand approaches. A senior market analyst with Bentek Energy expects coal-fired generation to be advantaged at least until the fall shoulder season.
