This State of Illinois Energy Tracker is a new Smarter Illinois Initiative to track energy cost and consumption for State of Illinois utility accounts. Electric and natural gas billing data is compiled by reporting Illinois utilities and agencies and relayed to the CMS utility database through the Energy Resources Center at UIC. Data is comprised of thousands of identified accounts for facilities owned or leased by the State of Illinois. New accounts will be added as utility data feeds are established and additional metrics and other relevant data will be displayed as available. This Energy Tracker will replace the annual “Illinois State Buildings Energy Expense Study” which was distributed to the State Legislature annually and was previously prepared manually using estimated data.

Electric (or Gas) Costs for Reporting Illinois Accounts Graph shows the annual cost for each reporting agency by fiscal year. The Electric (or Gas) Usage for Reporting Illinois Accounts Graph shows the annual electric or natural gas usage for each reporting agency by fiscal year. Graphs show the “Paying Agency” which isn’t always a reflection of “Using Agency” actual costs. CMS appears as a large Paying Agency as costs and usage includes those facilities that are paid by CMS Bureau of Property Management (BoPM) but occupied by other agencies and departments. This interactive Energy Tracker allows user to toggle between Electric Costs and Gas Costs by selecting “Gas Report” or “Electric Report” tabs, filter costs and usage by fiscal year by clicking the arrow under “Filter Costs by Fiscal Year” and selecting the appropriate fiscal year. Hovering over the lines on the graph show the total cost per fiscal year and the average cost per unit energy.

Illinois CMS Office Locations and Electric Usage Map shows all the zip codes with CMS Office Locations where the size of shaded area represents zip code area. User can select the Fiscal Year and hover over the zip code area to see the facility street, facility name, annual electric consumption and annual electric cost and pdfs can be downloaded using the “Download” function.

Illinois CMS Office Locations and Electric usage Comparison Chart compares the electric costs and usage for each facility. User can select the Fiscal Year and hover over the bar to see the facility street, facility name, annual electric consumption and annual electric cost. PDFs can be downloaded using the “Download” function.

The State Fiscal Year begins July 1st through June 30th. Monthly billing data is shown in the month closest to the actual billing period which may fall across 2 months. Efforts are underway to improve the quality of this data and require the cooperation of all the Agencies, utility supply and utility delivery. Please report any data errors or updates to jfarme1@uic.edu
