Automation Boosts Coal Power Plant’s Reliability, Energy Output While Cutting CO2 Pollution
A coal-fired power plant in West Virginia has improved plant stability and reliability while producing less carbon pollution after installing Emerson automation technologies.
Longview Power’s chose engineering and technology company Emerson to rehabilitate its Maidsville, West Virginia 700-megawatt power plant, previously plagued by frequent outages and poor performance.
After Emerson replaced Longview’s existing control system with its Ovation technology that manages operations, the plant is now one of the “cleanest, most efficient coal-fired plants in the United States,” according to Emerson.
The plant’s availability has risen to over 98 percent and net generation has increased by more than a third, all while using less fuel than before and producing 15 percent lower carbon dioxide emissions than the average US coal-fired power plant, the companies say. Longview also expects to save $3 million per year by avoiding unplanned outages.
The automation work was completed in 13 months, nearly twice as fast as a typical project of this scope, the companies say.
Meanwhile, after several coal company bankruptcies over the past couple years, the US Office of Surface Mining Reclamation and Enforcement is reconsidering how it can get guarantees from coal companies to fund efforts to repair the lands on which they have mined.
