Entergy Services, Inc. Smart Grid Project

From Open Energy Information

Entergy Services, located in New Orleans, Louisiana, will receive $4.6 million in funding to develop a smarter energy grid. The U.S. Department of Energy selected Entergy Services as one of 100 companies to receive federal stimulus funds as part of the American Recovery and Reinvestment Act of 2009.[2]

Entergy’s Deployment and Integration of Synchro Phasor Technology project is deploying phasor measurement units (PMUs), phasor data concentrators (PDCs), and state of the art decision support tools across Louisiana, Mississippi, Arkansas, and non-ERCOT portions of east Texas. These capabilities will enhance grid visibility of the bulk power system in near real-time, enable detection of disturbances which may produce instabilities or outages, and facilitate sharing of information with neighboring regional control areas. Additionally, the project will focus on training and education throughout the operations and engineering groups at Entergy to provide the foundational learning required to implement these advanced tools.[3]
