Isn't it possible that such a system will over-produce 99% of the year and that therefore, the marginal cost will almost always be $0?
'Take my energy and allow me to stop accelerating my flywheels which regulate production' seems more plausible than 'someone would always like more heat for something' (what?)
Or possibly 'take my energy and I'll cut off some of the people using spare energy to do low priority, low value computation for free'?
