DBRS Confirms St. Clair Holding, ULC at BBB, Stable Trend

DBRS Limited (DBRS) confirmed its rating of BBB with a Stable trend on the 4.881% Senior Secured Notes (the Notes) issued by St. Clair Holding, ULC (ProjectCo or the Issuer). The $171.8 million of Notes issued fully amortize and mature on August 31, 2031 (current outstanding balance of $130.7 million). ProjectCo indirectly owns Moore Solar LP and Sombra Solar, LP, two separate solar power sites located in St. Clair, Ontario (together, the Project), each with a nameplate generation capacity of 20 megawatts (MW).

ProjectCo benefits from attractive long-term fixed power prices under four 10-MW Ontario Renewable Energy Standard Offer Program power purchase agreements with the Independent Electricity System Operator (rated A (high) with a Stable trend by DBRS), maturing in February 2032, six months after the due date of the Notes.

The Project has shown robust results since achieving the commercial operations date in early 2012. Electricity generation for full-year 2016 and for the last 12 months (LTM) ending June 30, 2017, exceeded degradation-adjusted DBRS rating case estimates at P90 levels by 17% and 12%, respectively. Generation also surpassed the DBRS degradation-adjusted P50 levels by 11% and 6%, respectively, over the same periods. Total operating expenses were 8% below DBRS’s rating case estimates for 2016 and 19% below rating case estimates for the LTM ending June 30, 2017. As a result of higher generation revenue and lower expenses, the Project’s debt service coverage ratio (DSCR) of 1.55 times (x) for LTM ending June 30, 2017, and 1.65x for the year ending December 31, 2016, were higher than the DBRS rating case estimate of 1.38x.

DBRS may revise the rating case and take a positive rating action in the future if the Project continues to produce, on a sustainable basis: (1) electricity production at or above the degradation-adjusted P50 levels and (2) better-than-expected financial results measured primarily by DSCR. A future rating action would also consider the additional cash flow headroom resulting from a corporate restructuring that was completed in June 2014 that placed the payment of principal and interest ahead of income taxes. This restructuring results in the rating case DSCR improving to 1.40x in 2023, and increasing every year to 1.89x in 2030, well above the pre-restructuring rating case of a flat 1.38x DSCR.

The rating is constrained by (1) solar panel degradation risk and (2) the credit quality of the solar panel supplier providing a 25-year power output warranty; however, these risks are partially mitigated by (1) additional structural enhancements, including panel degradation reserve accounts; and (2) high break-even resilience for panel degradation at 2.6% per annum.
