    Fossil fuel plants, whose operating costs are primarily labor and fuel
    (mostly fuel), are at a disadvantage when interest rates go back up
    because such plants, if they do not own their own already established
    fuel supply chain, generally must make large seasonal or annual
    purchase agreements to get fuel at economically competetive rates. Such
    purchases incur financing, ergo finance charges at higher interest
    rates increase the net cost of fuel and result in less competetive
    energy. When such situations become tight, generators will generally
    switch from a full time generation situation to one of generating only
    or mostly for peak consumption periods, when they can charge the
    highest rates for their power.

    This is right, and not what I said. What I said was that windmills
    built and installed when interest rates are low find they are
    competetive if not outcompeting fossil fuel generators when interest
    rates go back up, specifically because of the fuel finance situation I
    detailed above.

    Actually, there are a few locations where hydroelectric 'batteries'
    have been built to take advantage of peak and off-peak demand changes,
    which adds value to off-peak generated power.

    Yes, and this is also a problem with intermittent energy providers like
    wind, solar, tides, etc where the power plant operator has little or no
    control over when they are able to generate or not. Hydro at least has
    some degree of control (excluding drought and fish migration conditions).
