Aggregation is when a group of customers join together to form a single, larger customer that buys energy for its members. A large buying group may be able to get a better price for the group members than you can get on your own. In Ohio, local communities are allowed, by law, to join their citizens together to buy natural gas and/or electricity as a group and thereby gain buying power to solicit the lowest price for the group's natural gas and/or electricity needs. Learn more about aggregation.  

30% of the Village of Granville’s greenhouse gas emissions come from the generation of the electricity we use in our homes and businesses.  By moving to an electric aggregation program where renewable energy is the default option, we are able to significantly reduce our greenhouse gas emissions. 

Granville Township Trustees use a different energy aggregator for their electric than the Village of Granville.  

Granville Township contracts with a private energy broker, Aspen Energy, which utilizes the electric generation supplier Dynegy (formerly Energy Harbor).  The default electricity of this plan is conventional (dirty) power and Granville Township residents must "opt in" to get renewable electricity.   

To opt into green electric, in Granville Township contact: 

• By email: jsell@aspenenergy.com  

• By phone: contact Jay Sell at 614-884-5300 ext. 234 (M-F from 8a.m.-5p.m.) 

Granville Township residents may opt-in to the Granville Green Electric program one of two ways. Whichever way you choose, we recommend having your AEP account information handy.   

By email: jsell@aspenenergy.com  
By phone: (M-F from 8a.m.-5p.m.) Village residents can contact Jay Sell at Aspen Energy at 614-884-5300 ext. 234.  Township residents can contact Energy Harbor at 1-866-636-3749.

Once enrollment has been confirmed by the utility, you will receive a welcome letter confirming enrollment along with the terms and conditions for the program. Residents enrolled in the renewable product will see at the top of the terms and conditions the Energy Incentive listed as “100% Wind Sourced Renewable Energy Certificates.”

NOTE: This does NOT apply to Village of Granville residents. See above for more information on Village contract with SOPEC.

AEP Ohio is the regulated utility that serves Granville and much of the Township.  AEP Ohio owns the power lines and they handle your electric billing including costs for transmission and distribution of the power you use. However, over a decade ago Ohio changed its laws to allow energy customers to choose the supplier for their electricity generation. This benefits us all because we can now shop for the best rates and choose where our power comes from and how it is generated. So, AEP handles transmission and distribution and you (or your community via aggregation ) can pick which company handles the generation of your power. The Village of Granville contracted with SOPEC and Granville Township have contracted with  Aspen Energy to manages the program with Dynegy (formerly Energy Harbor). 

In 2025, the fixed price for Granville's regular electric aggregation was 7.15 cents per kWh, while the 100% renewable wind energy was just 7.59 cents per kWh. For the average Granville home, the added cost to opt in to renewable electricity was about $3.67 per month - less than a latte!   

New electric rates will be negotiated when contracts expire in 2026.  Electric rates for all customers have increased recently and we anticipate that our rates will go up, but it is unclear how much. 

Electric rates fluctuate frequently. View an apples-to-apples electric comparison from Energy Choice Ohio to view current rates.

Not YET.   Aspen Energy and Dynegy have said they are making upgrades to their terms and conditions and billing system and after June 2026 Township customers with solar panels will be able to opt in to the renewable electric option for the energy they aren't producing.

Residents are free to opt-out of the energy aggregation program anytime for any reason without penalty or early termination fee.

Both SOPEC (for Village residents) and Dynegy (for Township residents) source wind energy from a number of generation facilities which, depending on cost and availability, may change over time in order to meet 100% of the required supply needs in a cost effective manner for residents. 

The current supply agreement specifies renewable energy from wind generation sources at a guaranteed rate through June 2026.  There is no provision in the contract to change the generation source or the cost to residents prior to June 2026, however, energy suppliers will consider solar energy in the future.
