Lake County voters approved all eight electrical aggregation ballot questions posed to them during Tuesday's election.
Unofficial results show voters in five municipalities and three townships approved the measures that allow residents to choose different electricity suppliers than ComEd through a series of public hearings and bidding processes.
Many of the unincorporated residents were voting on the issue again because of concerns about the wording of a similar question on the November 2012 ballot.
Unincorporated residents of Ela Township approved the initiative 288-147, and unincorporated Warren Township voters overwhelmingly approved the question 882-481, according to unofficial vote totals Tuesday night.
Voters in unincorporated Lake Villa Township approved the measure by a narrow 216-206 vote, with help from early voters and those who voted by mail, unofficial results showed.
In Green Oaks, voters gave the aggregation plan a lopsided 193-44 victory. Volo voters approved the same measure 68-42, according to the unofficial results.
In Beach Park, voters approved the proposal 746-517. Only 34 voters cast ballots on the topic in Old Mill Creek, but the measure was approved 19-15. Zion voters also approved the initiative with a 828-687 final tally, unofficial vote totals showed.
Scores of towns and townships throughout the state have approved similar measures over the past two years. Studies have shown residents have been able to save money by competitively bidding out the service.
