DBRS Morningstar Confirms Ratings on Northwestern Hydro Acquisition Co Inc. at A (low), Stable

DBRS Limited (DBRS Morningstar) confirmed the Issuer Rating and Senior Secured Bonds (the Bonds) rating of Northwestern Hydro Acquisition Co Inc. (the Issuer) at A (low) with Stable trends. The Issuer is a taxable corporation owned by Manulife Financial Corporation (Manulife; rated “A” with a Stable trend by DBRS Morningstar) and Axium Infrastructure Canada II LP (Axium; collectively, the Sponsors). The Issuer holds a 35% stake in Northwest Hydro LP (NWHLP) which, in turn, owns Coast Mountain Hydro Limited Partnership (CMHLP or ProjectCo). CMHLP is a special-purpose vehicle that owns and operates three run-of-river hydro facilities in northwest British Columbia (the Project). ProjectCo has been selling electricity to British Columbia Hydro and Power Authority (BC Hydro; rated AA (high) with a Stable trend by DBRS Morningstar) under three separate 60-year Energy Purchase Agreements (EPAs) since 2014. The EPAs feature fixed-energy pricing, which is indexed to British Columbia’s consumer price index for the entire contract term.

Results for 2019 significantly improved following several years of underperforming hydrology, including an exceptionally challenging year in 2018. Generation levels reached 1,205 gigawatt hours (GWh), representing an increase of 20% from 2018 and 96% of the forecasted long-term average generation (LTAG) of 1,256 GWh. The improvement almost exclusively resulted from increased water flows, which returned to 93% of LTAG. Net productivity, a key measure of actual to achievable generation, also increased to 96%, continuing a trend of general improvement from 85% in 2015. ProjectCo continues to make progress on operating improvements and DBRS Morningstar views the steady increase as indicative of ProjectCo’s ability to operate and maintain the facilities effectively. Actual operating costs for 2019 and budgeted costs for 2020 also remain relatively in line with rating-case expectations. Project performance, however, remains primarily constrained by resource availability and volatility. DBRS Morningstar notes that, without the late-year spike in November 2019 that nearly doubled waterflows from normal levels, generation performance in 2019 would have tracked noticeably lower than actual results. On the other hand, the overall improving trend for the year suggests that the hydrological cycle could be nearing the end of its current downcycle.

Debt servicing on the Bonds relies on distributions upstreamed from ProjectCo. Despite the much improved water flows in 2019, the timing of the BC Hydro cash settlement resulted in a relatively weaker reported debt service coverage ratio (DSCR) of 1.23 times (x). On an accrual basis, however, the DSCR would have been 1.37x, which better reflects actual performance and is within the lower bounds of rating expectations. Given that the Project is only two months into the current year, the Issuer’s 2020 DSCR projection of 1.52x is based on base-case assumptions. Because the Issuer only holds a minority stake in ProjectCo, bondholders only have recourse to the equity interest in ProjectCo instead of direct security over the underlying assets and cash flow as in a more standard project structure. This weakness is largely mitigated by the Sponsors’ collective majority interest in NWHLP and by strong contractual protections in the security package.

DBRS Morningstar may take negative rating action if the interest-only DSCR continues to materially underperform compared with the rating case.
