CHICAGO--(BUSINESS WIRE)--The Illinois Commerce Commission (ICC) today approved ComEd’s plan to construct one of the first utility-scale microgrid clusters in the nation in the Bronzeville neighborhood on the South Side of Chicago. The project, which has received more than $5 million in grant funding from the U.S. Department of Energy (DOE), will enable the study of how microgrids support the integration of clean energy onto the grid and increase grid security to keep power flowing even during extreme weather or a catastrophic event.

A microgrid is a small power grid with defined boundaries which can operate both when connected to the larger electric grid and as an “island” when there’s an interruption on the main grid. It draws on distributed energy resources (DERs), such as solar power, to serve customers within the microgrid footprint. These benefits extend to surrounding communities through better access to food, supplies, and public services.

“The importance of grid security will only continue to grow along with our increasing reliance on electricity,” said Anne Pramaggiore, president and CEO, ComEd. “This microgrid demonstration project will provide critical learnings on how to protect against and recover from disruptive events, including extreme weather, as well as physical or cyber-attacks. We’re glad to receive approval from the Illinois Commerce Commission and funding support from the DOE to move this important project forward and gain the valuable insights that it will bring to us, the state and the nation.”

“The new microgrid project will connect with an existing microgrid on the campus of the Illinois Institute of Technology, creating one of the most advanced clustered urban microgrids in the United States,” said Joe Svachula, vice president, Engineering and Smart Grid Technology, ComEd. “By connecting with the IIT microgrid, we’ll learn how to integrate microgrids with renewable energy resources and how to maximize the value of the interaction between two microgrids. It’s an important step forward in our effort to develop a more secure, resilient and reliable distribution system in the future.”

The demonstration microgrid project will be located within the Bronzeville neighborhood on Chicago’s South Side, in an area bounded from 33rd Street to the North, 38th Street to the South, State Street to the West, and South Dr. Martin L. King Jr. Drive to the East. Bronzeville was selected following a comprehensive study to evaluate locations where a microgrid could be located. The study developed an overall resiliency metric for small sections of ComEd’s northern Illinois service territory and identified locations where a microgrid could best address both security and resiliency, with a focus on public good. The project will serve an area that includes 10 facilities providing critical services, including the Chicago Public Safety Headquarters, the De La Salle Institute and the Math & Science Academy, a library, public works buildings, restaurants, health clinics, public transportation, educational facilities, and churches.

“The microgrid project complements Bronzeville’s long history of innovation,” said Alderman Pat Dowell. “Our vision for our historic community is centered on sustainability and accelerating the adoption of smart technology and infrastructure. Grid security and support for renewable energy sources are essential to realizing this vision and that’s what the microgrid will bring. The Bronzeville community looks forward to continuing a robust civic engagement process as we build out the components of the microgrid.”

The project builds upon ComEd’s smart grid platform and a continuous effort to advance the design and performance of the electric system serving northern Illinois. Phase I of the project will include 2.5 MW of load and require reconfiguration of an existing feeder, and installation of battery storage and solar PV. It will directly serve approximately 490 customers. Phase II of the project will add approximately 570 customers and an additional 4.5 MW of load and 7 MW of DERs, enough to meet the peak electricity demand of customers within the microgrid footprint and maintain service when the microgrid is islanded from ComEd’s grid. The completed project will serve approximately 1,060 residential, commercial, and small industrial customers.

The project will allow ComEd to take full advantage of work funded by two grants awarded by the DOE. This work includes developing and testing a microgrid controller that will control the cluster of the Bronzeville microgrid and the microgrid at IIT. A second DOE grant is focused on studying how large amounts of solar PV and batteries can be integrated into a microgrid.

The microgrid is expected to be completed in 2019 and its performance and impact, including a cost benefit analysis, will be studied over approximately 10 years. A broad range of metrics have been established to evaluate the project and its ability to positively impact the resilience of the energy system, the Bronzeville community and critical infrastructure.

The microgrid will be a key component of ComEd’s Community of the Future Initiative in Bronzeville, where it’s collaborating with residents to identify needs and opportunities to leverage smart grid technology and related services. Technology pilots planned or underway include an electric vehicle transportation service, off-grid wind and solar LED streetlights, outdoor interactive digital display technology providing community news, emergency alerts, way finding and free Wi-Fi. ComEd is currently conducting an Ideathon that exposes Bronzeville high school students to smart city and smart grid technologies and supports the development of skills in Science, Technology, Engineering and Math (STEM). Students will present final projects in April to a panel of judges and the teams will have the opportunity to win cash prizes up to $2,000.

Commonwealth Edison Company (ComEd) is a unit of Chicago-based Exelon Corporation (NYSE: EXC), the nation’s leading competitive energy provider, with approximately 10 million customers. ComEd provides service to approximately four million customers across northern Illinois, or 70 percent of the state’s population. For more information visit ComEd.com, and connect with the company on Facebook, Twitter and YouTube.
