Arden managed all aspects of construction for this onsite cogeneration plant, featuring a 7.5 megawatt gas turbine generator (GTG) with a heat recovery steam generator (HRSG) equipped with supplemental (duct) ring, to provide up to 60,000 lbs. of steam per hour. For operational flexibility, the plant included a dual-fuel system. The GTG is normally run on natural gas, with low sulfur diesel as the backup fuel. The plant also features all auxiliaries necessary to run the gas turbine and generator, including a local control panel and evaporative inlet aircooler for enhanced power production in the summer.
