Unit meets coal`s challenges: Florida project sets environmental marks while it scores a number of management points as well
Bringing in the cleanest-burning conventional coal-fired generating unit in the country in 39 months isn`t good enough for managers on a Florida project. They are making it a model of construction partnering and safety as well. The process has contained costs on the second unit at Orlando utilities Commission`s Stanton Energy Center. The new unit will match the 460-Mw capacity of the upgraded 1987 unit. But Timothy D. Slepow, OUC`s project coordinator, says the current budget has been cut from $522 million to $480 million. Unit 1 cost $516 million. {open_quotes}This is not a duplicate of unit 1,{close_quotes} says Hal E. Smith, executive partner of Black & Veatch, Kansas City, Mo., designer and construction manager. {open_quotes}In the permitting process, there was a tremendous effort to ratchet down to now-established best available control technology.{close_quotes} Unit 1, also designed by B&V, is operating at far below permitted emission levels, says Gregory A. DeMuth, OUC`s environmental director. Sulfur dioxide discharges are less than one-quarter of what permits allow, while emissions of nitrogen oxides and particulates also are considerably below requirements. Because of that operating record, the utility tried to get a {open_quotes}bubble{close_quotes} permitting concept applied to unit 2, DeMuth says. But state and federal environmental agencies {open_quotes}said unit 2 had to stand alone,{close_quotes} and pressed for even stiffer controls, he says. The major change is a selective catalytic reduction system that injects ammonia to slash nitrogen oxides emissions. {open_quotes}This will be the first coal-fired unit in the U.S. to have full volume SCR,{close_quotes} says Smith. {open_quotes}It`s previously been seen only on gas turbines. Subsequent to our doing it, others have been permitted.{close_quotes}
