Pitt-Ohio Express Inc. Renewable DC Microgrid Project
The Pitt-Ohio program successfully integrates solar and wind generation, along with battery energy storage and a DC network integration to power their Harmar Township distribution facility. The renewable energy component includes 50 kW of Solar PV, 5 kW of wind power, 70 kWHr of storage, and various power conversion integrations, while the facility’s internal distribution system includes a significant portion of Direct Current (DC) power distribution, indicated by the green lines on the one line diagram in Figure X. Figure Y is a view of the solar panels on the roof of the facility.In addition to Pitt-Ohio and the University of Pittsburgh, the other nine partners helping to make theprogram a success included the following industry organizations: Adam Solar Resources, Aquion Energy,BDA Engineering, Inc., Eaton, Elecyr, Emerson, Power Conversion Technologies Inc. (PCTI), SargentElectric, Universal Electric, and WindStax. All but Elecyr (New Hampshire) are located within 25 miles ofthe site, highlighting true community cooperation and the Pittsburgh region’s overall capabilities. Theproject construction phase began in late August 2015 and is scheduled for completion in early 2016. Pittprovided the engineering design, development, and concept of the project, and also took the lead role informing and managing the project team. Due to the success of the Harmar project, a new facility is beingplanned near Cleveland, Ohio using similar concepts and approaches.
