Oregon Clean Energy LLC on May 1 applied with the Ohio Power Siting Board for a Third Amendment of its Certificate of Environmental Compatibility and Public Need, covering minor changes for its electric generating facility in Oregon in Lucas County, Ohio.
The application offered this project schedule update: “As stated in the First Amendment, initiation of construction activities was scheduled for October 2014 to reach commercial operation by May 1, 2017. As a clarification, commercial operation is expected to be reached sometime between March and July 2017.”
One small change relates to the fact that the original application states that each heat recovery steam generator (HRSG) will be equipped with an ammonia injection grid and associated aqueous ammonia storage tank. Initially the on-site ammonia tank storage system was to consist of a 40 foot long, 9-foot diameter double-walled tank allowing for a maximum of 18,600 gallons of 19% aqueous ammonia to be stored on-site, given a maximum volumetric tank capacity of 85%. In order to ensure high plant availability, the contents of the tank would not have been allowed to drop below 20% capacity. Therefore, a minimum of 4,400 gallons would have been stored on-site at all times. The design basis of each tank has now been modified, and will instead be 25,500 gallons net, each, or 26,800 gallons gross. This equates to a total gross volume of 53,600 gallons. The size is driven by the desire to have 10 days of storage for inclement weather conditions that can impact delivery.

The Ohio board on March 9 signed off on the prior amendment of its May 2013 approval of the 799-MW Oregon Clean Energy combined-cycle project.
