DBRS Morningstar Confirms Ratings on Trillium Windpower, LP at BBB (high) With Stable Trends

Project Finance
November 25, 2021

DBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Series 1 Senior Secured Amortizing Notes (the Notes) rating of Trillium Windpower, LP (the Issuer) at BBB (high) with Stable trends. The Notes, which fully amortize on February 15, 2033, had $229.862 million of the $315.462 million principal outstanding as of September 30, 2021.

The Issuer is a special-purpose entity created to finance and indirectly own the 22.9-megawatt (MW) Conestogo and 124.4-MW Summerhaven wind farms in Ontario (collectively, the Project). The Project benefits from long-term fixed-power prices under feed-in tariff (FIT) contracts with the Independent Electricity System Operator (IESO; rated A (high) with a Stable trend by DBRS Morningstar) for 20 years. The Coronavirus Disease (COVID-19) pandemic has not materially affected the Issuer’s operations or financial performance.

The rating confirmations reflect the Project's continued and consistently strong electricity generation, with a reliable operating and financial performance of more than seven years. Actual debt service coverage ratios (DSCRs) have been well above the rating case minimum DSCR of 1.46 times (x), averaging 1.61x over the seven-year period since 2014 and reaching 1.66x for 2020. For the last 12 months ended September 30, 2021 (LTM 2021), the DSCR remained commensurate with the rating level at 1.51x; however, it was dampened because of (i) lower generation and revenue resulting from relatively lower wind resources in Q1 2021 and Q2 2021 and (ii) higher-than-budgeted operating and maintenance (O&M) costs resulting from parts & labour overage from the replacement of parts nearing end of life and timing of some labour and services costs. The Project achieved 102% of the P50 generation target for 2020 and 94% for LTM 2021.

The Project’s Summerhaven facility is subject to economic curtailment but is compensated for almost all curtailment by the IESO, which forecasts the foregone energy that would have been generated free of curtailment based on the wind resource and other assumptions.

The Issuer is majority (51%) owned by Cordelio Power LP (Cordelio Power) through wholly owned subsidiaries, having purchased in 2018 the entity that formerly owned the Project (NextEra Energy Canada Partners Holdings, ULC) from NextEra Energy Partners LP (whose parent company is NextEra Energy, Inc.). The remaining 49% is owned by Axium Infrastructure as of January 2021. Headquartered in Toronto, Cordelio Power was launched in June 2018 by the Canada Pension Plan Investment Board (CPPIB; rated AAA with a Stable trend by DBRS Morningstar) to complete the purchase of a portfolio of wind and solar assets in Ontario. The Project continues to be operated by NextEra Energy Canada Operating Services, Inc. with no change in contracts. Cordelio AdminCo Inc., an indirect wholly owned subsidiary of CPPIB, administers the Project, with Administrative Service Agreements in place.

The ratings are supported by the fixed-price FIT contract, the Project's strong and consistent operating track record, and the strength of the owner and operator. The ratings are constrained by the inherent uncertainty with wind forecasts, O&M cost management, and exposure to negative hourly Ontario energy price (HOEP) for the Summerhaven wind farm. These risks are partially mitigated by the Project’s strong actual performance, ability to maintain cost discipline, and bidding strategy that largely eliminates negative HOEP exposure.

A further rating upgrade is unlikely in the near future. DBRS Morningstar may take a negative rating action if there is material and sustained underperformance, causing a DSCR consistently below 1.45x.
