With Ontario’s power industry now disposing of massive and increasing amounts of excess generation, one of the challenges for the public in understanding this development is penetrating the fog of confused terms the industry uses to speak about the phenomenon. Scandalously, Ontario’s government-controlled power sector does not tally the cost to consumers of the ongoing wastage.
Ontario’s power industry takes on the affectation of referring to surplus power as “baseload”. The affliction for consumers is not a surplus of baseload generation but a surplus of take-or-pay generation, some of it stupidly expensive. Some of Ontario’s take-or-pay generation is legitimately considered baseload (nuclear, run-of-river hydro, cogeneration), but increasing amounts of it are intermittent junk generation, particularly wind but also in some circumstances, such as winter, solar. (Solar generation in winter in causes more severe than necessary evening ramping requirements for flexible supply resources exclusively on days with low day-time loads.)
