Microgrid. A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. [1] It is able to operate in grid-connected and in island mode. [2] [3] A '' stand-alone microgrid '' or '' isolated microgrid '' only operates off-the-grid and cannot be connected to a wider electric power system. [4]
The microgrid solicitation was a design-build project and was awarded to a joint venture of Schneider Electric and Black and Veatch in 2016. Engineering design for the project was completed in 2017, and construction started in 2018. Construction completion and project commissioning are both expected in 2019.
