10 MW Power Plant & Grid
Inglett & Stubbs International is currently furnishing and installing several lease power plants in Afghanistan. Each of the lease power plants is similar in that ISI is procuring and installing the power generation equipment and setting it up onsite. ISI is also installing a power distribution grid at each location to distribute the power from the new lease plant to the end-user on the base.
ISI’s lease plants are designed with current needs and future growth of the base or camp in mind. The projects utilize multiple diesel-powered generators that are paralleled together using complex switchgear to produce 13.8kV power that is distributed over the power distribution grid. With our lease plants, ISI also provides local centralized monitoring, fuel storage and fuel pumping equipment, all medium-voltage cabling for interconnections and emergency safety shutdown devices in the event there is a fault in the power plant. This equipment is brought into the base and installed on a plot of land designated by the U.S. Military typically in a central location that will serve the base or camp. Typically, ISI is able to have these style power plants in place and operating forty-five (45) days after receiving the notice-to-proceed from the customer. Along with our lease plants, ISI is also able to offer and install the power distribution grid. Refer to “MV Distribution” section for more details of this service in-theater. For one particular project located in northwestern Afghanistan, ISI will furnish, install and maintain a 10MW power plant and a 13.8kV power distribution grid consisting of overhead distribution lines with service laterals from the overhead lines extending underground to feed pad-mount transformers. Main distribution panels will be installed feeding from the pad-mount transformers that will connect to the end-user loads.
This project includes a 10MW 13.8kV power plant, 13km (8 miles) of overhead lines that will be installed in three phases. There is also 5.25km (3 miles) of underground laterals feeding out to pad-mounted transformers. We started this project in Setpember of 2011 with site preparation for the new plant and construction of the housing and support camp required to support power plant and power grid operations. Our first delivery of concrete poles arrived in late October 2011 and within a few weeks we had made good progress with pole and cross arm installation. The overhead cable and connections for the first phase are well underway by mid January in preparations to connect the first loads to the plant by the end of January 2012.
ISI also has two other projects similar in scope include a 5MW power plant in northern Afghanistan which was commisioned on September 12, 2011, and a second 10MW power plant in eastern Afghanistan which was commisioned on November 3, 2011. These projects include a combined total of 650 meters (2,130 feet) of overhead lines and 6.8km (1.3 miles) of underground laterals.
ISI is responsible for daily operations and maintenance of the power plants and power grids for all three projects.
