First Solar - PGT 2, 3, & 4

Perrysburg, Ohio

Mechanical

Each of the three facilities features a fully automated central utility building housing chillers, pumps, heat exchangers, and air compressors coupled with desiccant dryers. The 3 facilities chiller plants create a total of over 30,000 tons of cooling to serve the HVAC and process cooling needs of the plants. Additionally, the 3 plants utilize centrifugal and packaged screw air compressors to create oil-free, sub-zero dewpoint compressed air for process needs. JDRM coordinated closely with installing contractors to modularize the piping racks to accelerate schedule and provide premium quality through shop fabricated pipe modules. In addition to process needs, JDRM designed the front offices featuring numerous meeting rooms, commercial kitchens, and locker rooms.

Electrical

Electrical design included two separate substations served both at 138kV from the local utility. The substation serving PGT-2 & PGT-3 consists of three 30MVA base rated transformers with tie feeders at the 15kV level between all three allowing for back feed of switchgear in the event one transformer is offline. The Central Utility Building at each facility included multiple 5kV and 480V main-tie-main switchboards for increased reliability. Cable tray was utilized for large tool feeders while busway was used for small feeders 200A and less.

Plumbing

Each of the facilities feature robust plumbing systems to serve occupant needs. Each facility has numerous restroom pods to conveniently serve floor employees. JDRM works closely with First Solar to locate all emergency safety showers and eyewash units throughout the plant floor to ensure safety and protection of all workers. In addition to plant floor needs, JDRM designed shower areas and full commerical kitchens for each building.

Technology

The first solar campus and PGT-2, PGT-3, and PGT-4 are state of the art facilities for the manufacture, testing, storage, and shipping of solar panels. The facilities leverage multiple technology systems to accomplish this goal and secure the sites. Structured cabling is generally category-6 with WLAN coverage throughout the facilities. Physical segregation is provided between manufacturing and building network cabling systems. Primary and secondary server/telecom rooms are provided for the general building and multiple telecom cabinets serve the manufacturing and warehouse spaces. Redundant fiber backbone feeds are provided to all rooms & cabinets utilizing disparate routes to maximize redundancy. Access to the sites is limited by controlled entry gates and secured vestibules. Each site has a security room that can control gates and doors for entry. Smart card readers and credentials are used for staff with video intercoms provided for visitors and delivery of material. The exterior of all sites are monitored with IP surveillance cameras. On the interiors surveillance cameras are provided at key locations. Each security room has a surveillance video wall for viewing of cameras as well as camera controls.

Project Details

Two new manufacturing facilities and a new R & D center built over the course of six years totaling 4,825,000 square feet of space under roof. The new manufacturing facilities allowed for significant growth in manufactuing capacity and represented the first facilities in North America for First Solar dedicated to production their new larger panel format. JDRM designed the HVAC, Process Cooling, Plumbing, Electrical, Fire Protection and Technology systems for all three facilities.
