AEP Generating Company — Moody's downgrades AEP, AEP Texas, Ohio Power and PSC of Oklahoma, outlooks stable

The downgrade of AEP considers the downgrades of these three utility subsidiaries and recognizes that its consolidated capital program, which includes the North Central Wind projects along with growth at its lower risk transmission and distribution networks, will be executed with significant use of leverage. In addition to increasing debt at its subsidiaries, AEP is also relying more heavily on parent level debt to support the equity needs of its operating utilities. Historically, AEP’s capital structure had incorporated a very limited amount of holding company debt, a key credit positive compared to many holding company peers. Currently, however, parent level debt represents about 20% of consolidated AEP debt, and the ratio will likely remain near this level.

Environmental, social and governance considerations incorporated into our credit analysis for AEP and its subsidiaries are primarily related to carbon regulations and social risks related to demographic and societal trends, as well as customer and regulatory relations. AEP has moderate carbon transition risk within the regulated utility sector as the majority of its energy is generated by fossil fuels. Although still heavily reliant on coal generation, AEP is focused on transitioning to a cleaner energy future. As of 2019, AEP’s consolidated 31,524 MW generating portfolio included about 45% coal-fired resources, versus about 66% in 1999, and about 17% in renewable generation, compared to around 4% in 2005. The North Central Wind projects will add close to 1,500 MW of wind generation bringing renewables to about 20% of the portfolio. From a governance perspective, financial strategy and risk management are key considerations.

The rapid spread of the coronavirus outbreak, severe global economic shock, low oil prices and asset price volatility are creating a severe and extensive credit shock across many sectors, regions, and markets. The combined credit effects of these developments are unprecedented. We regard the coronavirus outbreak as a social risk under our ESG framework, given the substantial implications for public health and safety. However, we do not consider the impact of the coronavirus outbreak to be a material credit driver for AEP.

As events related to the coronavirus continue, we are taking into consideration a wider range of potential outcomes, including more severe downside scenarios. The effects of the pandemic could result in financial metrics that are weaker than expected; however, we see these issues as temporary and not reflective of the long-term financial or credit profile of AEP.

Outlook

The stable outlooks for AEP, AEP Texas, OPCo and PSO recognize that the companies continue to benefit from supportive regulatory frameworks that provide numerous riders and trackers to assure recovery of the investments the utilities are making to grow rate base. The outlooks consider that the sizable capital programs are focused on lower risk transmission and distribution networks and renewables, which facilitate the organization’s clean energy transition and reduce its carbon transition risk.

FACTORS THAT COULD LEAD TO AN UPGRADE OR DOWNGRADE OF THE RATINGS

Factors that could lead to an upgrade

Upward ratings pressure could develop if there were to be an increase in cash flow, perhaps due to regulatory activity or load growth, or a reduction in leverage such that we could expect key financial credit metrics to strengthen. For example, at AEP a ratio of CFO pre-WC to debt sustained above 15%, at AEP Texas a ratio of CFO pre-WC to debt sustained above 15%, at OPCo a ratio of CFO pre-WC to debt sustained above 20%, and at PSO a ratio of CFO pre-WC to debt sustained above 20%. A reduction in parent leverage, such that the ratio of parent to consolidated debt moves closer to 10%, could put upward pressure on AEP’s rating.

Factors that could lead to a downgrade

There could be downward pressure on the ratings if a more contentious regulatory environment were to develop in any of AEP’s jurisdictions, if ongoing capital investments cannot be recovered on a timely basis, or if financial metrics deteriorate. For example, at AEP a ratio of CFO pre-WC to debt sustained below 13%, at AEP Texas a ratio of CFO pre-WC to debt sustained below 12%, at OPCo a ratio of CFO pre-WC to debt sustained below 16%, and at PSO a ratio of CFO pre-WC to debt sustained below 16%.
