Microgrids represent a rapidly growing distributed energy market segment, and Capstone is well positioned to participate. While there is no one definition for what a “microgrid” is, it typically refers to a combination of distributed energy resources (DERs) able to operate connected to a utility grid, but also able to operate completely isolated from the grid. Ensuring reliable power for the mission-critical data center was the main priority of the state-of-the-art facility. A main driver of the purchase was resiliency that the utility could not provide. Traditional data centers rely on power from the utility and have banks of batteries that keep servers and equipment running during short power loses. A standby emergency generator is typically used for longer outages. Because of the critical nature of the complex, the microturbine is configured to provide power and therm

Case Study 1At the heart of this microgrid is a Capstone C600 Signature Series natural gas-fired microturbine that simultaneously creates electricity and thermal energy for heating and cooling. The C600S microturbine is a dual-mode model, able to operate connected to a utility grid or operate stand-alone, providing power to critical loads when the utility is unavailable.
The clean exhaust from the microturbine is brought to a 200-refrigeration-ton capacity absorption chiller for building cooling or can be directed to a heat exchanger to provide up to 3MMBTU per hour of hot water for building heating. This combination of outputs is called combined cooling, heating, and power (CCHP) and provides more efficient use of fuel than the traditional utility electric power and separate thermal systems. The C600S microturbine is controlled by two fully redundant Capstone controllers for maximum resiliency. Additional distributed energy resources in this microgrid include solar panels that can produce up to 180 kilowatts of power, wind turbines with a capacity of 24 kilowatts, an energy storage capacity of 231 kilowatt hours, and a traditional 1,500-kilowatt backup diesel generator. Tying all these separate power generation technologies together is a smart microgrid controller, featuring cutting-edge technology with the ability to control and dispatch using advanced optimization models. |
