On March 23, the City Council approved a new contract for residents who are currently in its municipal aggregation program. The two year agreement with Integrys provides cost savings over the ComEd rate, and also includes the purchase of renewable energy credits (RECs). One REC is produced for each megawatt hour of renewable electricity put on the grid, and will help finance renewable energy generation. The REC option will add approximately $1.60 per month to the electricity bill for an average Highland Park home.
