The mix

Herewith, a pretty chart showing Newfoundland and Labrador Hydro's total generation output (in GWh, with percent of the total) from thermal (largely Holyrood) and hydraulic sources, over the past decade. (Churchill Falls, Menihek, isolated diesel, and the feeble wind industry output, excluded.)

[Data source: Nalcor/NLH annual reports, passim.]

Thermal once accounted for well over 30% of the total — a figure which is sometimes still, and, at best, erroneously, bandied about.
