When a company requires lot more energy, power plants are expected to produce lot more.
When a power plant produce a lot, the low consumption rates tend to get cheaper. It's gets cheaper to produce energy as the demand increases.
This is, of course, considering the input material is not scarce, like hydro power plants or wind power. Everything else (coal, oil, nuclear, gas, solar) should be easy to increase supply/demand.
