The automation work was completed in 13 months at the Maidsville, West Virginia plant that had previously been plagued by frequent outages and poor performance. Emerson replaced Longview’s existing control system with a new Ovation technology that manages operations across the plant. Availability has increased to over 98 percent and net generation has increased by more than a third, all while using less fuel and producing 15 percent lower carbon dioxide emissions than the average U.S. coal-fired power plant. Longview expects to save $3 million per year by avoiding unplanned outages.
“Emerson’s ability to manage this comprehensive automation project within a very aggressive timeframe was instrumental in helping us bring the plant back online and generate electricity as quickly as possible,” explained Steve Nelson, Longview’s Chief Operating Officer. “Since we began using the new Ovation controls we’ve experienced drastically improved plant stability, enabling us to provide more power to the grid – and generate more revenue.”
