Priority Power Management, LLC (PPM), a Texas-based independent energy management and consulting services firm, has delivered an end-to-end electric energy solution to Woodford Express, LLC (WEX), a subsidiary of Xplorer Midstream LLC (Xplorer), for a natural gas processing project in Grady County, Oklahoma.

WEX’s Grady plant provides natural gas processing services in the South Central Oklahoma Oil Province (SCOOP) shale play. The design includes 210 MMcfd of natural gas processing capacity from two trains of 60 MMcfd and 150 MMcfd, with accommodations for two additional 200 MMcfd processing trains in the future.

Important considerations in the early planning stages were the availability of sufficient electrical infrastructure to serve the initial and future electrical loads of the Grady plant, and the cost of receiving electric service – both from an upfront capital expense and ongoing operating expense perspective.

PPM developed electric rate models to analyze estimated future operating and upfront capital expenses for several build out and operational scenarios, from which a multi-phase plan was conceived. PPM consulted with WEX with respect to the negotiation of agreements for electric service with Public Service Company of Oklahoma (PSO), a subsidiary of American Electric Power, to provide electric service to the Grady plant initially from a 25 kV primary distribution feeder, then ultimately from a new 138 kV transmission line.

Subsequently, WEX expanded PPM’s scope to include engineering, procurement and construction (EPC) services to develop the electrical infrastructure WEX would need to receive service from PSO and power the Grady plant. PPM delivered a full turnkey EPC solution that included a 25 kV primary distribution system with capacitors integrated for power factor correction, and a 120 MVA 138 kV/25 kV high voltage substation. The substation was designed with full transformation and breaker redundancy for maximum reliability and was energized this past week.
