North Aurora residents will still be paying less for electricity in the fall than ComEd customers, under a new aggregation contract the village has arranged.
And they can feel "greener" because the electricity will be wind-generated.
The village recently picked Verde Energy USA, which is based in Connecticut, for a one-year term.
Verde will charge 5.329 cents per kilowatt-hour, from September through May 2014. ComEd currently charges 5.511 cents, and plans in October to drop that to 5.473 cents.
In June 2014, the Verde rate increases to 6.499 cents through August 2014.
Customers can opt out of the agreement and pick a different provider.
The contract also covers small commercial users.
Earlier this month, the village ended its contract with another electricity supplier, Integrys, as its rate was increasing and becoming higher than ComEd's.
"We are pleased that we were once again able to obtain a rate that is not only less than ComEd's Price-to-Compare, but is also for 100 percent renewable energy," North Aurora President Dale Berman said in a statement.
North Aurora was one of the first towns in the area to adopt electrical aggregation. Residents gave village officials permission to do so in April 2011. Aggregating the load and having the village negotiate a contract was hoped to result in lower costs.
