Project Finance
June 13, 2025

DBRS Limited (Morningstar DBRS) 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 the Guarantor, 2016 Comber Wind Limited Partnership (ProjectCo), 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) in Essex County, Ontario. ProjectCo benefits from fully contracted power prices at attractive rates under two feed-in tariff (FIT) contracts (for each of Comber East and Comber West) with the Independent Electricity System Operator (IESO). As at December 31, 2024, approximately $201.8 million of the Bonds were outstanding.

KEY CREDIT RATING CONSIDERATIONS
The Project commenced commercial operations in November 2011, generating an average of approximately 457.5 gigawatt hours (GWh) annually to YE2024, which is 4.4% more than the annual P90 production forecast of 438.4 GWh and 5.4% 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.) wind assessment. The Project has not achieved the P50 generation level because of less favourable wind conditions compared with the plan, although it approximated P50 in 2013 and 2014. Revenue for the Project mirrors generation. In 2024, the generation achieved was 430.6 GWh, approximately 1% below the rating-case forecast as a result of unfavourable wind conditions, with an estimated generation loss of 6.5 GWh as a result of outages.

CREDIT RATING DRIVERS
Morningstar DBRS may consider a positive rating action if the Project's generation level and debt service coverage ratio (DSCR) outperform the rating case on a sustained basis. A negative credit rating action could be triggered by frequent forced outages as well as material and sustained underperformance versus the rating case.

FINANCIAL OUTLOOK
For the 12 months ended December 31, 2024, the Project achieved a Morningstar DBRS-adjusted DSCR of 1.43 times (x), higher than the rating case projected average and minimum DSCRs of 1.40x and 1.38x, respectively. The ProjectCo was able to achieve a higher DSCR due to a higher realized sales price, and lower O&M expense compared with the rating case forecast.

The FIT 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 $149.84/MW hour (MWh) for 2024, and the market price received in Ontario.

CREDIT RATING RATIONALE
The rating is anchored by the (1) fixed effective energy price, supported by a high credit quality offtaker: IESO; (2) robust operational performance; and (3) experienced sponsor with reputational and strategic stake. The main challenges include (1) wind resource risk, (2) power production forecast and operating risk, and (3) exposure to negative wholesale electricity prices.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE CONSIDERATIONS
There were no Environmental, Social, or Governance factors that had a significant or relevant effect on the credit analysis.
