Tes_raleigh_tank

Pepco Energy Services (PES) provided an energy services performance contract project to the State of North Carolina, and selected DN Tanks to build a 2.7 MG (million gallons) stratified chilled water Thermal Energy Storage (TES) tank on the state capital campus in downtown Raleigh.

The precast, prestressed, wire-wound concrete TES tank is at the heart of this significant energy savings project. Coupled with a new high efficiency packaged chilled water plant, this TES tank is capable of delivering 27,260 ton-hrs of cooling capacity. The system is the primary chilled water source for 3.5 million square feet in 20 buildings.
