  • Dominion’s Indy Solar Projects Go Into Service

    Dominion announced that it has placed into service a group of solar generation projects in Marion County, Ind., that will generate up to 28.6 MW of electricity. The three projects, known as Indy Solar I, II, and III, were acquired in July 2013 from Sunrise Energy Ventures LLC, based in Minnetonka, Minn. All three projects […]

  • 1.05-GW Iowa Wind Expansion Moves Forward

    MidAmerican Energy Co. is already the top ranked, rate-regulated utility owner of wind generation in the U.S. and with 448 new wind turbines being added in Iowa—the largest wind expansion in the state’s history—its hold on that position will be further strengthened. In November, the company announced it had reached an agreement with Highland Wind […]

  • Transformer Fire Takes Down Nuclear Plant

    Arkansas Nuclear One Unit 2 was taken offline the morning of Dec. 9 due to a transformer fire in the site switchyard. Operators at the plant declared an “Unusual Event” at 8 a.m. CST and notified the Nuclear Regulatory Commission (NRC) of the situation. An Unusual Event is the lowest of four nuclear emergency classifications […]

  • Crystal River $1.18B Decommissioning Plan Submitted to NRC

    Duke Energy submitted its decommissioning plan to the Nuclear Regulatory Commission (NRC) this week for the company’s retired Crystal River nuclear plant in Florida. The 860-MW plant, located about 85 miles north of Tampa, went into service on March 13, 1977. It has been shutdown since September 2009 when engineers discovered a delamination, or separation […]

  • Europe’s Most Efficient Coal Plant Comes Online

    With an electrical efficiency of 45.95%, the Lünen hard-coal-fired power plant, located on the Datteln-Hamm Canal in the state of North-Rhine Westphalia, Germany, is Europe’s cleanest and most efficient. The 750-MW unit is owned by Trianel Kohlkraftwerk Lünen GmbH und Co. KG and has been online in continuous operation since Dec. 1. The plant had […]

  • Major Milestone Achieved at Concentrated Solar Plant

    AREVA announced that on Nov. 29 the first steam production was achieved at the concentrated solar power (CSP) plant it is constructing near Dhursar in the state of Rajasthan, India. The plant is Asia’s largest CSP installation and will be operated by Reliance Power. The 100-MW plant was approved for carbon credits in July under […]

  • Construction Permit Extended (Again) for Watts Bar Unit 2

    The Nuclear Regulatory Commission (NRC) has extended the expiration date of the construction permit for the unfinished Unit 2 at the Watts Bar Nuclear Power Plant (WBN) to Sept. 30, 2016. WBN is located about 10 miles south of Spring City, Tenn., and is owned by the Tennessee Valley Authority (TVA). TVA requested the extension […]

  • Improve Coal Flow by Using Insert Technology

    Coal-fired power stations rely on storing coal in large bunkers or silos. Over time, changes in the type and quality of coal can lead to poor flow during discharge, creating production inefficiencies and significantly reducing storage capacity. Manual intervention is frequently used to promote flow; however, this is a hazardous process for operators and fails […]

  • New Options Allow Silo Cleaning Without Confined Space Entry

    Anyone operating a coal-fired power plant has faced the challenge of keeping coal-handling equipment free of blockages and plugging. Not only do material flow problems interrupt smooth plant operations, but they also require dirty, sometimes dangerous, and often unscheduled maintenance work. As in many other industries, remote-controlled tools can help solve this problem. Bulk material […]

  • Public Utilities Commission Scrutinizes Xcel Cost Overruns

    The Minnesota Public Utilities Commission (MPUC) will hire a nuclear engineering consultant to investigate cost overruns associated with Xcel Energy’s Monticello Nuclear Generating Plant Life Cycle Management/Extended Power Uprate Project. The project, at an estimated cost of $320 million, was authorized by the MPUC in 2009 and included necessary upgrades to increase the 600-MW plant […]
