Columbus lists July 2026 target for Circuit 7221 grid-conversion work

The City of Columbus’ Power Capital Improvement Projects program lists July 2026 as the expected time for a notice to proceed on Phase 1 of the Circuit 7221 voltage-conversion project in north Columbus.

The city describes the notice as expected, rather than confirmed. The available project information does not provide an exact date when a notice to proceed was issued, and it does not establish that Phase 1 construction has begun.

Planned work on aging electrical infrastructure

The project would convert aging 7,200-volt electrical circuits to 14.4-kilovolt service. Columbus identifies the work as an effort to address aging electrical infrastructure in north Columbus.

The city says the conversion is intended to improve electrical reliability and safety. Those are project goals, not completed outcomes; the city’s available information does not say the conversion work has been finished or that all customers have been moved to higher-voltage service.

Circuit 7221 is the project identified in the city’s Power CIPs program. The North Substation is also listed among the project entities in the city’s information.

Area covered by the project

The planned work covers a substantial service area in north Columbus. The city places the project primarily between Cleveland Avenue and Interstate 71, extending north to Dublin-Granville Road.

That geographic description identifies the area for the voltage-conversion work, but the available page does not provide a customer count or specify how many customers would be affected during Phase 1.

Schedule remains an expectation

Once Phase 1 receives a notice to proceed, construction is expected to last approximately 15 months, according to the city. That duration is an anticipated schedule, not a confirmed completion date.

The expected July 2026 notice to proceed is the next project milestone identified in the available city information. The page does not state a total project cost or provide a confirmed start date for construction.

For residents and businesses in the north Columbus project area, the city’s listing signals a planned upgrade to the electrical system, while leaving the exact timing of a notice to proceed and construction start unconfirmed.
