Research: Action Rating: Moody’s downgrades Ohio Power to Baa1, outlook stable

Around $3 billion in affected debt

New York, August 22, 2022 — Moody’s Investors Service (“Moody’s”) has downgraded the issuer and senior unsecured ratings of Ohio Power Company (Ohio Power) to Baa1 from A3 and changed its outlook from negative to stable. Ohio Power is a transmission and distribution utility subsidiary of American Electric Power Company, Inc. (“AEP”, stable Baa2).


“We expect Ohio Power’s credit metrics to remain weak relative to other A3-rated utilities for at least the next two years,” said Nana Hamilton, vice president – principal analyst. Significant increases in debt to fund Ohio Power’s high capital expenditures continue to put negative pressure on a credit profile already weakened by the loss of the commission-approved transition endorsements in 2018. The next security plan (ESP) from Ohio Power, which will become effective in June 2024, will be an important factor in determining the utility’s long-term credit quality beyond 2024.

Although Ohio Power benefits from the use of approved riders/tracking mechanisms under its current ESP, utility credit metrics have been significantly lower than levels achieved prior to 2018. This is partly due to an increase in debt to finance heavy investments in its transmission. and distribution infrastructure. The utility’s reported long-term debt has grown rapidly over this period and is now 70% higher than it was in 2018. Over the next three years, we expect annual capital expenditures to hold steady. near recent highs of around $800 million minimum. and projecting that the utility will continue to fund its negative free cash flow with additional debt.

As Ohio Power’s debt has grown, its cash flow has been negatively impacted by the expiration of old credit support covenants associated with Ohio’s transition to competition. In 2016-18, these endorsements generated approximately $250 million in cash flow per year, contributing significantly to strong pre-WC CFO/debt ratios above 30%. With their expiration, we expected the pre-WC CFO/leverage ratio to remain in the 16% to 20% range. However, with higher debt balances incurred to fund high capital expenditures, Moody’s now expects Ohio Power’s pre-WC CFO-to-debt ratio to be maintained in the 14% to 16% range, which is more indicative of a Baa1 rating.


Ohio Power’s stable outlook reflects our expectation that regulation in the state will continue to support utility credit quality, including the use of covenants to recover most costs and a return on investment of distribution and that there will be a new credit support PSE implemented in 2024. The outlook reflects our view that, going forward, the company will generate CFO pre-WC to debt ratios in the range 14% to 16% as it executes its major capital expenditure plan.


Factors that can lead to an upgrade

An increase in cash flow and/or a reduction in leverage that reverses recent trends and leads to a pre-WC CFO/debt ratio consistently above 16% could put upward pressure on the rating.

Factors that may lead to a downgrade

If Ohio’s regulatory environment, or the new ESP 2024 in particular, becomes less credit-friendly, resulting in less recovery certainty or increased regulatory lag, or if the pre-W/C CFO to debt remains lower at 14% for an extended period, the rating could move down.
