OH SB121

Expands the definition of "infrastructure development" to include construction, upgrading, extension, or any other investment in transmission or distribution facilities owned and operated by natural gas companies.

Adds a return on infrastructure development costs for economic development projects equal to the natural gas company's authorized return on equity from its most recently approved rate case.

Increases the monthly per-customer recovery limit under the infrastructure development rider from $1.50 to $3.00 per billing period for all approved projects.

Establishes a regulatory deferral mechanism allowing natural gas companies to defer infrastructure development costs exceeding the monthly limit, with carrying costs at the company's long-term debt rate, to be recovered in subsequent years.

Requires natural gas companies to recover the same infrastructure development rider amount from every customer uniformly.
