DBRS Morningstar Confirms TransAlta Corporation at BBB (low) and Pfd-3 (low) With Stable Trends
Utilities & Independent PowerDBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Unsecured Debt/Medium-Term Notes credit rating of TransAlta Corporation (TAC) at BBB (low) and TAC’s Preferred Shares credit rating at Pfd-3 (low). The trends are Stable. The confirmations reflect TAC's (1) reasonable contractual profile, (2) low fuel risk and cost competitiveness, and (3) operational expertise. These strengths are partially offset by (1) merchant generation risk, (2) structural subordination of cash flows, and (3) expansion risk.
DBRS Morningstar notes that on October 5, 2023, TAC announced that it acquired the 40% stake of TransAlta Renewables Inc. that it did not previously own. In November 2023, TAC entered into a definitive share purchase agreement with an affiliate of Energy Capital Partners, the parent of Heartland Generation Ltd. and Alberta Power (2000) Ltd. (collectively, Heartland). For additional details, please see DBRS Morningstar’s press releases dated July 11, 2023, and November 2, 2023, respectively.
The Province of Alberta's (Alberta; rated AA with a Stable trend by DBRS Morningstar) merchant spot electricity prices decreased to $152 per megawatt hour (MWh) in Q3 2023, compared with $221 MWh in Q3 2022. TAC's Alberta hydroelectric facilities, which represent more than 90% of Alberta's hydro generation plants, were able to benefit from the strong merchant prices. The Alberta hydroelectric assets generated approximately 28% of TAC's consolidated adjusted EBITDA in last 12 months ended September 30, 2023. The strong merchant sales resulted in TAC achieving strong financial metrics for 2022. DBRS Morningstar expects the financial metrics to remain solid over the medium term.
TAC's contract profile remains strong, with more than 90% of TAC's consolidated free EBITDA (after maintenance capital expenditures) coming from either long-term contracts with a weighted-average life of approximately 11 years or from hydro generation plants in Alberta. DBRS Morningstar believes TAC currently benefits from the energy-only market in Alberta and from its hydro generation assets. However, TAC's exposure to the power market in Alberta remains a concern because most power-generation assets in Alberta are without long-term power purchase agreements.
DBRS Morningstar notes the credit ratings incorporate the structural subordination of TAC's debt to the nonrecourse debt at its projects and subsidiaries. DBRS Morningstar believes the structural subordination is significantly mitigated because most of TAC's modified cash flow comes from assets with no or minimal debt. However, DBRS Morningstar notes that if the project-level debt increases significantly, structural subordination could become a greater concern, which could result in a negative credit rating action.
The Stable trends reflect DBRS Morningstar's view that (1) the exposure to merchant risk in Alberta for 2024 is well hedged and (2) TAC’s business risk and 2024 consolidated credit metrics are likely to continue supporting the current credit ratings. DBRS Morningstar does not expect to take any positive credit rating action in the near to medium term. However, a negative credit rating action could occur if (1) Alberta has a sustained weakening in its power market, (2) the current contractual profile deteriorates materially, or (3) the consolidated cash flow-to-debt ratio falls below 17.5% on a consistent basis.
