![]() ![]() With the addition of the fast start natural gas-fired synchronous machine, the microgrid will ensure that the campus will remain powered for extended hours during power outages. While we have assets in place to help keep critical systems and locations operational, the microgrid solution can help us to achieve the objective of having the entire campus operational from a combination of the Solarbe assets and additional generating assets on campus. During extreme severe storm situations, it is important that our campus, particularly Power Control, Warehouse, Fleet Maintenance, and Data Centers maintain a continuity of power. While this is an exciting project, these Distributed Energy Resources (DER) are operating only when the grid is available. The second was the creation of our solar Smartflower garden, and the third was the construction of the battery energy storage system (BESS) with a nameplate capacity of 1 MW/4 MWh AC. The first part was the installation of 1.85 MW DC solar PV on the rooftops of three campus buildings and two solar car canopies. Solarbe was commissioned and operational in September of 2020 and consisted of three parts. In order to support its sustainability goals, Cobb EMC partnered with Gas South (a wholly subsidiary of Cobb EMC) in 2019 on an innovative solar and battery energy project called Solarbe. ![]() The project implementation of the microgrid project will be in the third quarter of 2021 and planned project completion in the second quarter of 2022. ![]() Cobb EMC selected Caterpillar and Yancey Power Systems to build a microgrid on the campus of its headquarters in Marietta, Georgia. Cobb EMC is one of the nation’s largest electric cooperatives in terms of both members and revenue. ![]()
