TRAININGVirginia City Hybrid Energy Center-Training is key to first-time runningThe new US-based 585MW Virginia City Hybrid Energy Center is part of Dominion’sresponse to meeting a projected growth in demand for electricity of 4,000MWs from its customersby 2017, or enough electricity to <strong>power</strong> one million homes. WIP has <strong>the</strong> story.The Virginia City Hybrid EnergyCenter [right] - a US$1.8 billionproject - is apparently ‘well onschedule and on budget’ for commercialoperation by July 2012.Construction began in 2008, is now 98%complete, following <strong>the</strong> November 2011‘First Fire ‘ - a key milestone in <strong>the</strong>commissioning process for 585MW stationFossil fuels, such as coal, oil and naturalgas, are non-renewable sources of energy.Dominion's fossil-fueled <strong>power</strong> stationsgenerate more than 40% of <strong>the</strong> <strong>power</strong>provided to its customers.“Top-quality training, a dedicated workforceand advanced technologies are <strong>the</strong>keys to being a pacesetter in fossil-fuelgeneration,” a company spokesman toldWIP.Since coal-fired <strong>power</strong> stations producegases and airborne particles known as flyash, Dominion has a comprehensiveapproach to protecting <strong>the</strong> environment.Its <strong>power</strong> stations use a variety oftechniques to reduce harmful emissions,including electrostatic precipitators andsystems that reduce nitrogen oxide, suchas selective catalytic reduction.The 585-megawatt Virginia City HybridEnergy Center is part of Dominion’sresponse to meeting a projected growthin demand for electricity of 4,000MWfrom its customers by 2017, or enoughelectricity to <strong>power</strong> one million homes. Itwas five years ago in 2007 when The ShawGroup Inc. was first awarded anengineering, procurement andconstruction contract to develop <strong>the</strong> siteby Dominion.Once <strong>the</strong> plant is up-and-running VirginiaCity will be one of <strong>the</strong> cleanest <strong>power</strong>stations of its kind. The circulatingfluidised bed unit will use coal and up to20% biomass for its fuel. A Virginia Techeconomic impact study concluded that <strong>the</strong>station will generate about US$440 milliona year in tax revenues and o<strong>the</strong>r benefitsfor Wise County.The station will provide nearly 1,000jobs during construction and require apermanent staff of more than 75 peopleonce it begins operating. It will createabout 350 mining jobs. Dominion has provideda task-tailored comprehensive training& education programme for all itsworkers, as well as full health & safetytraining.[Left] David A. Christian, chief executiveofficer for Dominion Generation, whichoperates electricity-generating stationsfor Dominion Virginia Power, told WIP:"First fire back in November 2011 proveda major milestone for <strong>the</strong> Virginia Cityproject and signified a shift fromconstruction to a station focused onexcellent operations."He said: "There have been manytalented and dedicated people who haveworked over 12.5 million hours to get tothat point. This sets <strong>the</strong> stage for successfulproject completion in <strong>the</strong> Summer of2012."Initial cleaning, heating and testing atVCHEC will be performed using fuel oil.Part of <strong>the</strong> activity surrounding first firingwill be <strong>the</strong> release of steam – calledsteam blows – which is a commontechnique used to clean <strong>the</strong> piping beforesteam is sent to <strong>the</strong> turbines that spin <strong>the</strong>station's electric generator.Advanced circulating fluidized bed technologyis proven clean-coal technologythat also enables <strong>the</strong> using of run-of-minecoal, waste coal and renewable energysources, such as wood waste. CFB technologycombined with modern post-combustioncontrols has low emissions of sulfurdioxide, nitrogen oxide, particulatematter and mercury.WIPInternet linkwww.dom.com32M ARCH 2012 • WORLDWIDE I NDEPENDENT P OWER
