Energy Aggregation Information

What is aggregation?

Your energy bill includes two parts: a delivery fee and a supply fee. While delivery service is provided by a set utility, Ohio law allows residents to choose their gas and electric suppliers.

To help residents and small businesses secure lower energy rates, the City of Troy competitively bids supply contracts and negotiates rates on behalf of the community. Participants are automatically enrolled in the aggregation program but may opt out at any time. To further increase buying power, Troy joined with other area communities as part of the Miami County Communications Council, creating a larger aggregation area.

Electric Aggregation 

AES Ohio delivers electricity to Troy residents and issues your monthly bill. Constellation NewEnergy has been selected as the electric aggregation program supplier for the Miami Valley Communications Council Electric Aggregation Program, which includes the City of Troy and 17 other local communities. The goal of the aggregation is to provide a lower, stable electricity rate for residents and small businesses through the selection of a lower-cost supplier.

Beginning January 1, 2026, the supplier is Constellation Energy, providing a fixed rate of 9.049¢ per kWh through December 31, 2026.

For comparison, AES Ohio’s standard rate is 9.45¢ per kWh (as of June 1, 2025). This rate is updated annually in June. For the most recent comparison, visit the Energy Choice Ohio Apples-to-Apples Comparison Chart.

Gas Aggregation

Troy launched its natural gas aggregation program for residents and small businesses in October 2025. Participants receive delivery service from CenterPoint Energy, which also issues monthly bills. CenterPoint Energy is planning a merger with National Fuel in 2026—watch your bill for updates regarding changes.

The gas aggregation offers a fixed rate of $0.6625 per hundred cubic feet (ccf) from October 2025 (November billing) through May 2027, supplied by Archer Energy.

While CenterPoint’s standard rate may be lower during summer months, the aggregation’s fixed price protects participants from rate increases during the higher-cost winter season. For the most recent comparison, visit the Energy Choice Ohio Apples-to-Apples Comparison Chart or review your CenterPoint bill for current supply rates.
