Bloomington's Ameren Bills:
Why They're So Much Higher Now
McLean County homeowners on Ameren Illinois have experienced some of the most dramatic electricity rate increases in recent state history – and the causes are structural, not temporary.
- Summer 2026 Supply Spike
+50%
- In summer 2026, Ameren's electricity supply price jumped roughly 50% — from around 8¢/kWh to about 12¢/kWh — causing typical residential bills in Bloomington to increase by $40–$60/month or more during the summer season.
- MISO Capacity Auction — Root Cause
22x
- The MISO regional grid auction — which sets capacity costs passed directly to Ameren customers — cleared at $666.50/MW-day in 2026, a 22x increase from the prior year's $30/MW-day. Coal plant retirements tightened supply faster than new generation came online.
- ICC Delivery Rate Increases
$357M
- The Illinois Commerce Commission approved a $308.6M delivery rate increase for Ameren in December 2024, followed by a $48.4M grid modernization surcharge in December 2025. These are passed directly to every Ameren customer in McLean County and statewide.
- Current All-In Ameren Rate (2026)
~15.5¢
- Bloomington homeowners on Ameren's default supply are now paying approximately 15.5¢/kWh all-in — up from roughly 8¢/kWh in 2021. That's a 94% increase over five years. Ameren has signaled it intends to file another rate increase in 2026.
- Why this matters for solar: The higher your current electricity rate, the stronger the financial case for solar tends to be — because every kWh your panels produce offsets a more expensive kWh from Ameren. A solar lease or PPA that fixes your rate at ~10¢/kWh saves you significantly more when Ameren is charging 15.5¢ than it did when Ameren was charging 8¢.

Your Bloomington Energy Options:
Compared Honestly
There’s no single right answer for every Solar in Bloomington home. Here’s what each option actually means — and when each one makes the most sense for central Illinois homeowners.

Solar Lease
A solar company installs panels on your roof. You pay a fixed monthly amount — typically lower than your current Ameren bill. No upfront cost, no system ownership required.

Power Purchase Agreement
You pay per-kWh for the solar energy your panels produce — often below your current Ameren rate. Provides predictable costs without the need to own the system.

Solar Loan
You own the system and finance it over time. Loan payments are often offset by Ameren bill savings — and qualifying systems in Bloomington may be eligible for Illinois Shines SREC income.

Cash Purchase
No monthly payment — the strongest long-term financial return for homeowners who can invest upfront.

Battery Backup
Add home battery storage to your Bloomington home. Keep power on during outages, reduce peak-hour Ameren costs, and maximize solar value under Illinois's current energy policies.

- State program available to Bloomington homeowners
Illinois Shines (SREC-II) in Bloomington & McLean County
Solar in Bloomington is in Ameren Illinois territory—which currently has better Illinois Shines enrollment slot availability than ComEd territory in northern Illinois. This is a meaningful advantage for Bloomington homeowners considering owning solar systems right now.

Fixed-Price SREC Contract
Qualifying Bloomington solar installations receive a 15-year contract for Solar Renewable Energy Credits — a long-term additional income stream on top of your electricity savings. Ameren is required by Illinois law to purchase these SRECs.
Typical SREC Value — Ameren Territory
Illinois Shines SREC income for typical Ameren-territory homeowners with qualifying systems has historically ranged from $10,000+ to well above that over the 15-year contract period, depending on system size and SREC block pricing at enrollment.
Ameren vs ComEd Slot Availability
Ameren territory — including Solar in Bloomington and McLean County — currently has more Illinois Shines enrollment capacity available compared to ComEd territory. For homeowners timing their installation, this is a relevant factor right now.
Ownership Requirement for SRECs
Illinois Shines SRECs go to whoever owns the solar system. Solar in Bloomington homeowners who lease or use a PPA generally do not receive SREC income — the installer retains it. This is one factor to weigh when comparing financing options.
