What municipal leaders are saying

“This is a great partnership! Thanks so much for all of your help. You have made this process go very smoothly and everyone feels so much better prepared than they felt with any other Electric Aggregation rollout. They also really appreciate your willingness to provide support for the more in-depth/detailed inquiries they receive.” — Assistant Village Administrator

“I am truly appreciative to you and I want to thank you for all that you have done during my time with this organization. Out of all the programs I managed for the Village, Electrical Aggregation was the easiest because of your assistance and genuine willingness to help. Thank you and you are very much appreciated by the Village, our residents and especially me.” — Assistant to the Village Manager

FEATURED

  • ComEd's Environmental Disclosure

    26 September 2024: For the 12 months ending 30 June 2024, ComEd procured RECs, ZECs & CMCs totaling 90% of deliveries to retail customers. The percentage volumes of electricity sources remained unchanged over the previous 12-month period.

    REC = Renewable Energy Certificate; ZEC = Zero Emissions Credit; CMC = Carbon Mitigation Credit

  • ComEd Rate Just Released

    13 September 2024: 6.47¢ is the new residential supply rate for the non-summer months from October 2024 to May 2025. That is a decline from the current summer rate of 6.9¢ per kWh. For the last 12 months, the monthly PEA variant averaged a small credit of 0.15¢ per kWh.

  • Riverside Offset 200 Million Lb Coal Burned

    The Village of Riverside may be the only community in Illinois to retain a 100% Green / Renewable Energy Aggregation program continuously since 2012. Current program continues to October 2025. With the large increase expected in the ComEd rate in 2025, the fixed rate program is likely to provide resident savings next summer as well.

  • Changes Afoot at ComEd

    22 June 2023: ComEd has eliminated its plus-or-minus 1/2-cent cap for the monthly variable Purchased Electricity Adjustment (PEA). There is no longer an imposed limit.

    Also, ComEd did not procure a full load this year and may turn to the daily market to purchase power. It remains to be seen if these moves will result in increased volatility.

  • Good News, Bad News

    The ComEd supply rate is expected to decline slightly for the upcoming Energy Year June 2024 - May 2025.

    The Carbon-Free Energy Resource Adjustment (initially a credit of 4.3¢ per kWh), has flipped to a charge of 1.3¢ as pf May 2024. This charge supports nuclear generation and appears in the Taxes & Fees portion of the ComEd bill.

  • Buffalo Grove Renews Green Aggregation

    “We’re happy that Buffalo Grove recently renewed its Green Electric Aggregation Program, retaining our high ranking with the EPA, and all at zero added cost to the ComEd rate,” Mike Skibbe, Deputy Village Manager told us.

    The renewal commences at meter read dates in March 2023.

  • Hawthorn Woods: Preserving for Legacy

    Pamela Newton, Chief Operating Officer, is racking up awards: Governor’s Hometown for Environmental Initiatives, National America in Bloom, International Dark Sky Association, International Audubon Community.

    Their Electric Aggregation program, designed to promote sustainability initiatives, renews February 2023.

  • ComEd Warns of Scammers

    Discover ComEd’s tips on avoiding and reporting imposters, scams, and identity theft which increased once the moratorium on door-to-door soliciting (during the pandemic) was lifted.

    When residents are scammed or misinformed via nefarious tactics, our customer service works with the ratepayer to ensure their supply service is rightfully returned to their desired supplier.

  • Kane County Receives EPA Award

    The County’s mission “to improve its environmental, economic, and social sustainability” was furthered through its green aggregation program.”

Pierog; Energy and Environmental Committee Madam Chair and Commissioner Mavis Bates; Sharon Durling, President and CEO, Illinois Aggregation Consultants; Jodie Wollnik, Director, Department of Environmental and Water Resources; Ivy Klee, Resource Management Coordinator

  • Illinois Aggregation Consultants Awarded National Women's Business Certification

    WBENC Certification is the gold standard for women-owned businesses in the US.

    As Energy Consultant to over 100 communities in Illinois since 2011, we are delighted to have first received this designation in 2021.

  • Throwback: Tinley Park one of First in Illinois

    In 2018, the Environmental Enhancement Commission, then chaired by Antonio Halek, led efforts to become one of the first municipalities in Illinois to establish the ComEd Price Match Renewable Aggregation.

    Program suspended in 2022 due to reduced gas production during the Pandemic followed by the war in Ukraine creating price volatility; some analysts suggest this “perfect storm” may dissipate in 2023.

  • Palos Park Second in the Nation!

    Ann Debortoli, a Director at MC Squared Energy Services, presented the EPA Green Power Community Certification to now former Mayor John Mahoney and current Mayor Nicole Milovich-Walters. Palos Park was the second community in the USA to establish an Electric Utility Price Match 100% Green program.

How we serve:

Deep Expertise

Following stints in strategic risk management consulting at PwC and 15 years as a vice president in banking and real estate, Sharon Durling, President and CEO, participated in Illinois’ first Municipal Electric Aggregation Programs in 2011. Instrumental in establishing industry best practices in a new market segment, Durling has worked with 100 governmental bodies, serving a population approaching two million.

Innovation

We were the first Energy Advisor in the State of Illinois to pivot toward renewable energy for a wide swath of the community—at zero added cost—to enable our municipalities to skyrocket to the EPA’s highest rankings of green communities, outpacing states on both coasts. Flyover country will not be left behind!

Customer Centric: for Every Resident

When markets and events upend the status quo, so do we. We work with suppliers to develop new programs to bring new benefits such as renewable energy and community solar subscriptions for ratepayers. In some instances, a civic grant may be procured for the municipality. Our fellow Illinois residents are the reason we work.

Proprietary Process: Serving Mayor, Council, and Staff

We manage a robust process from supplier negotiation to staff training, supporting the municipal project leader through every step from board presentations through final reports. We have worked with every power supplier that has engaged aggregation in Illinois and work closely with ComEd. Our expertise and breadth of population served are unmatched.
