> The authors note that given the size of past Yellowstone eruptions, and the span of time between them, the rate that energy builds below the volcano is only around 1.5 gigawatts - less heat than a typical power plant sheds. Yellowstone currently bleeds heat at a rate of about 4.5 to 6 gigawatts, mostly through heated water moving below the surface. You'd thus (theoretically) only need to increase the heat bleed by around 35% to stop energy accumulating and stop future eruptions.

That sounds overly simplistic. Volcanic eruptions aren't caused by energy accumulation alone (otherwise every eruption would have the same magnitude), and AFAIK it's mostly the accumulation of gas that triggers eruptions, and in many cases the gas is in fact steam…
