(1) Unfavourable generation mix As a result of the current generation mix, NSPI is dependent on international suppliers for its fuel supply, exposing the Company to volatile global pricing. This exposure, combined with continued investment...
AI summary NSPI's reliance on international fuel suppliers and coal-based generation has led to higher electricity rates. While the Muskrat Falls project will reduce coal use, coal-based assets will still contribute to the generation mix beyond 2029. Federal and provincial regulations require coal plant closures by 2030, necessitating significant investment in replacements.
