General Description
Numerous utilities are supplied to Technology Park clients, including steam, electricity, city water,
river water, cycle (cooling) water, nitrogen, natural gas, compressed air, and bulk gases.
Steam: Steam is supplied to the site by Duke Energy's on-site facility. Current annual average
load is 32M lb/hr., with an all-time high peak of 92M lb/hr.
Electric Power: The site is supplied with electric power by a dedeicated 46 kV to 13.8 kV American
Electric Power (AEP) substation with two 13,800 volt underground feeders. Total capacity is 24 MVA with
a current summer peak load of 15 MVA. AEP has 100% redundancy in their substation.
City Water: Potable water for the site is supplied by the West Virginia Water Company. The current
capacity is 850 gpm, which is double the present and future known requirements.
River Water: River water is supplied to the site from the South Charleston Plant via a 14-inch
underground line. River water is used for fire water make-up, cooling tower make-up, and once-through
cooling systems. Capacity is 1250 GPM and is currently operating at approximately 60% of capacity.
Cycle (Cooling) Water: Cooling water is recirculated between the major buildings and the cooling
towers. Ten cooling towers exist at the site, located at Buildings 704, 705, 740, 770, 771, 773, 777,
791, 2000 and 6000. The cooling towers located at Buildings 705 and 777 are currently out of service.
Each in-service cooling tower is presently running at capacity. The cooling towers
located at Building 2000 are 20 years old and will need to be replaced within the next five years.
Nitrogen: The Technical Park has two sources of nitrogen. One is a pipeline fed from Institute’s
Praxair air separation unit though the South Charleston Plant’s distribution system. The second is a
Praxair liquid bulk storage facility. The total combined capacity of these systems is 55,000 cfh.
Currently the pipeline system can supply 100% of low pressure nitrogen requirements during peak flows
and will handle the requirements for a new laboratory building. All of the high pressure requirements are
supplied from the Praxair liquid bulk system.
Natural Gas: The site has a six-inch natural gas (methane) line running through the site fed by
Cabot Gas. Capacity is approximately 120,000 cfh with current usage at 40 to 90,000 cfh. There is also
a two-inch gas (methane) line fed by Mountaineer Gas of West Virginia which feeds the heaters at the
wellness center.
Compressed Air: The compressed air for the site is produced by two oil-free centrifugal air
compressors with a
total capacity of 3000 cfm with current usage of 1700 cfm.
Bulk Gas: The bulk gas area has the following facilities: hydrogen, ethylene, ethane, oxygen,
carbon monoxide, carbon dioxide, nitrogen, butene, propylene, hexene, isopentane and butadiene. The
following systems and their storage capacities are owned and/or operated by Technical Park Operations:
hydrogen 800 lbs, ethylene 58,500 lbs, ethane 8500 lbs, oxygen 46,160 lbs, carbon monoxide 3260 lbs,
carbon dioxide 1365 lbs, and nitrogen 74,202 lbs. The remainder of the systems are owned and operated
by Dow business units.
Each of these systems is designed for specific customer capacity requirements.
