Local context, in plain English.
Springfield is a metro of about 113,394 in central illinois. The utility footprint here is dominated by Ameren Illinois, which means every Springfield buyer is on one of those utilities for delivery — wires, meter, outage response — regardless of which supplier they pick on the supply side.
Because Illinois is a deregulated supply market, Springfield buyers can pick from a multi-supplier shelf and lock a fixed rate for 12, 24, 36, or 48 months. The supplier sets the per-kWh rate; the utility still bills, owns the wires, and responds to outages. We surface the licensed shelf, rank by methodology, and let the buyer pick the term that aligns with their planning window.
Estimated savings for Springfield buyers based on the 2025–2026 Seenra customer book sit in the up-to-14.6% range on the supply line. Actual savings vary by ZIP, by load profile, and by the day you lock — never guaranteed, always disclosed in the quote.
