The appellant, an independent power producer, appealed a trial judgment that found the respondent breached a power purchase agreement but awarded no damages due to unreliable evidence.
The trial judge had concluded that the respondent failed to include an inter-area transmission credit in its avoided costs calculations, but dismissed the damages claim because the appellant's expert evidence was deemed unreliable.
The Court of Appeal upheld the finding of breach but held that the trial judge erred in dismissing the damages claim entirely.
Relying on Martin v. Goldfarb, the Court found that where a significant loss is proven but the quantum is difficult to assess, the plaintiff should not be denied compensation.
The appeal was allowed and a new trial on damages was ordered.
