Electric Aggregation
In 2013, Mt. Vernon residents voted to let the city negotiate electricity rates on behalf of residents and small businesses. This is called electric aggregation, and it helps keep electricity costs low.
The City has consistently secured rates at or below Ameren's default supply rate.
Homefield Energy is the City's chosen supplier.
The current rate of $0.11789 per kWh, locked in from June 1, 2025 to May 31, 2026.
What is electric aggregation?
Electric aggregation lets the City buy electricity for residents and small businesses at a group rate. Illinois passed Public Act 096‑0176 in 2009, allowing municipalities to use electric aggregation to help residents and small businesses save money. You can read the full text of the law here.
The city seeks bids and negotiates the fixed rate per kWh from a supplier and the length of the contract.
Who Can Participate?
- All residents within Mt. Vernon city limits
- Small business within the city limits using 15,000 kWh or less
