Siemens Researching Microgrids with New Jersey Solar + Storage Project

Siemens USA has launched a microgrid research and demonstration environment at its U.S. Corporate Technology headquarters in Princeton, New Jersey. The Princeton microgrid integrates technologies across the company’s “Smart Infrastructure” portfolio, including PV, battery storage, electrical power infrastructure, building management systems and microgrid control systems, allowing researchers to study each component of the microgrid and the system as a comprehensive solution. The living lab, which was developed utilizing automated microgrid design tools, will also result in a 50% reduction of the Princeton facility’s CO2 footprint.


Researchers are trying to validate these technologies in order to provide the market with a blueprint of how microgrids can be flexibly operated in similar applications such as universities, office parks and industrial sites, while reducing the adverse impacts of energy uncertainty. The microgrid will be powered by the renewable energy generated by the PV system, storing excess energy to be used when needed. The team will also introduce tests to see how the technology behaves in various scenarios, including completely islanding the system from the grid.

“Microgrids continue to become an integral part of our modern-day energy systems because they not only provide an answer to threats like extreme weather and power outages, but will also play a significant role in helping cities and communities meet their challenging CO2 reduction targets,” said Dave Hopping, president and CEO, Siemens Smart Infrastructure North America. “Our goal through this unique research project is to demystify the difficulties around installing and operating a microgrid to provide a clear path towards clean energy and carbon neutrality.”

The microgrid’s loads and energy assets are controlled by Advanced Microgrid Controls, an integrated software and hardware solution composed of Siemens’ SICAM microgrid controller and Russelectric switchgear and transfer switches. Russelectric, a Siemens Business, has been providing power solutions to mission-critical facilities for 50 years.

The microgrid will connect to the Siemens MindSphere cloud-based platform with data analytics and system monitoring technologies with support provided by the MindSphere team located in Austin, Texas. The system features a new dashboard for both building occupants and engineers that provides real-time data on how the grid is operating and performing.

“The microgrid market has been growing quickly and we have the opportunity to test how each component of these systems work as a whole,” said Xiaofan Wu, Princeton Island Grid Project manager, Siemens Corporate Technology. “The beauty of our R&D work in Princeton is that we have the power to investigate and validate highly innovative technologies continuously in a real environment, resulting in a clear blueprint for a more efficient and flexible microgrid system that can be replicated all over the world.”

Siemens has been developing microgrid technology in the United States over the past decade, including its work with Blue Lake Rancheria in Northern California and the Commonwealth Edison Bronzeville microgrid in Chicago. The company’s portfolio can address every component of a microgrid system from management software to battery storage and electrical power infrastructure.
