Late September marked the placement of Shepard's two stacks, the 'crown' of the plant, and the last major external component of the generation facility.
The stacks are a significant facility component - they signify the building is almost complete, and they act as the exhaust for the natural gas-fired turbines – the heart of the facility.
While the stack placements took only 20 minutes each once the lift started, many hours of planning and preparation went into the moment. This major feat was completed at night – when wind is at a minimum.
The height of each stack is 180 feet, equivalent to a 22-story building. The bottom halves were built on-site, and the top halves manufactured off-site. The 150,000-pound, 19-foot diameter top stacks were placed by a large crane, and then workers took about 10 hours welding the top and bottom halves together.
With the stacks in place, the construction focus turns to completing all the piping, electrical and control systems inside the building. Construction is on track for Shepard's start up in 2015.
