Small and DIY interconnection requirements
Ohio's statewide rules apply: systems sized up to 120% of your usage, and monthly excess credited at the standard-service-offer energy rate only, a few cents post-HB6. documented
Short form application with a $50 fee, one-line diagram, equipment certification, and a required disconnect switch. After install and inspection: Certification of Completion, then permission to operate once the meter is set. reported
Timeline runs about 20 to 35 business days for residential, the shortest of Ohio's big three. On time-of-use rates Duke nets hourly, which changes the math on self-consumption. reported
PUCO's own warning worth knowing: credits attach to the premise and may be lost if you relocate or stop taking service. documented
