Crystal Lake Electric Aggregation Program 

All City of Crystal Lake residents and small businesses have been automatically enrolled unless they:

  1. Chose to opt out during the opt out period
  2. Have previously switched to another Alternative Supplier
  3. Participate in an hourly-rate program

The City receives a bulk electric supply rate that is available to residents and small businesses; this is called electrical aggregation. Crystal Lake has provided the Electric Aggregation Program since 2012.

The City recently renewed the program and contracted with Dynegy Energy Services for a 24-month period. This began in October 2018 and will end in October 2020. During this time, there will be a fixed rate of 7.098¢ per kWh.
