DBRS Morningstar Confirms Ratings on Comber Wind Financial Corporation at BBB, Stable Trends

Project Finance
June 20, 2023

DBRS Limited (DBRS Morningstar) confirmed Comber Wind Financial Corporation’s (the Issuer) Issuer Rating and the rating on the $450 million Series 1 Senior Secured Bonds (the Bonds), due November 15, 2030, at BBB with Stable trends. The Issuer is the financing vehicle of 2016 Comber Wind Limited Partnership (ProjectCo and the Guarantor), a special-purpose entity that owns the 82.8-megawatt (MW) Comber East project and the adjacent 82.8-MW Comber West wind project (together, the Project) located in Essex County, Ontario. As at December 31, 2022, approximately $254.9 million of the Bonds were outstanding.

The Project commenced commercial operations in November 2011, generating an average of approximately 465.3 gigawatt hours (GWh) annually to YE2022, which is 6.2% above the annual P90 production forecast of 438.4 GWh and 7.2% more than the rating case forecast of 434.3 GWh. The P50 planned generation level is 500.7 GWh, as per the resource consultant's (Underwriters Laboratories Inc. or UL) wind assessment. The Project has not achieved the P50 generation level because of less favourable wind conditions compared with the plan; although, it approximated the P50 in 2013 and 2014. Revenue for the Project mirrors the generation. In 2022, the generation achieved was 464.6 GWh, approximately 7% more than the rating case forecast as a result of favourable wind conditions. The Project has not experienced any material operational issues.

Since the first full year of debt service in 2013, ProjectCo's annual debt service coverage ratio (DSCR) has been above the rating case projection minimum DSCRs 1.38 times (x). For the 12 months ended December 31, 2022, the Project achieved a DBRS Morningstar adjusted DSCR of 1.56x, higher than the previous year because of relatively higher generation and revenue.

DBRS Morningstar notes that the 2021 reported DSCR is changed to 1.39x from 1.43x. The reason for the change is the recognition of maintenance capex of $1.496 million which was not included in 2021 DSCR calculation.

ProjectCo benefits from fully contracted power prices at attractive rates under two feed-in tariff contracts (for Comber East and Comber West) with the Independent Electricity System Operator (IESO). The contracts expire 12 months after the maturity of the Bonds. For 20 years until November 2031, the IESO pays ProjectCo the difference between a fixed but partially indexed price, which was $146.4/MW hour for 2022, and the market price received in Ontario.

A negative rating action could be taken if the Project consistently underperforms below the P90 level. The rating is constrained by (1) the inherent uncertainty of wind forecasts, (2) operating and maintenance cost management, and (3) exposure to negative Hourly Ontario Energy Price (HOEP). These risks are partially mitigated by the Project’s actual performance, ability to maintain cost discipline, and minimal exposure to negative HOEP.

There were no Environmental/Social/Governance factor(s) that had a significant or relevant effect on the credit analysis.
