On January 9th, 2006, I posted the following message under the article Playing with Fire – Part II:
LRMC works when your have an adapted system. Things like congestion and price spikes make a lot of noise and the expected value of short run deviates a lot from long run values. To mitigate congestion and price spikes - both of which signal whole system risk of failure - ultraquality is needed based on both resources of the supply side and on the demand side.
The dimension of the demand side, however, is well undeveloped. So, EWPC innovation opportunities abound in the demand side, which definetly should include differentiated customers interruption costs, and not only the power bill in the rationing optimization. That is how the whole system - not its parts - is adapted to resolve both the stability of output prices and recovering of capital costs, by making the expected value of short run marginal costs get closer to the long run marginal costs.
