Ameren Small Commercial Electric Supply Rate Falling 10%

Ameren has filed with the Illinois Commerce Commission new Retail Purchased Electricity Charges (electric supply rates) for the period beginning June 1, 2020

The Retail Purchased Electricity Charges are the largest component of the Price to Compare (PTC). The PTC also includes the Supply Cost Adjustments and a bypassable transmission rate. A bypassable Purchased Electricity Adjustment is not included in the PTC.

For residential customers, due to tiered, usage-based pricing applicable in the non-summer (current period) versus a flat summer rate, an apples to apples comparison of Ameren's new supply rate versus the current rate is not applicable

The June 1, 2020 filed Ameren residential (BGS-1) Retail Purchased Electricity Charge is 3.152¢ per kWh for the summer 2020 period. This is lower than the current Retail Purchased Electricity Charges for both non-summer usage tiers, which are 3.485¢/kWh for usage 0-800 kWh, and 3.246¢ for usage >800 kWh

The June 1, 2020 filed Ameren BGS-2 Retail Purchased Electricity Charge, for secondary voltage, is 3.779¢ per kWh for the summer 2020 period, about 10% lower than the current charge
