An Electricity Procurement Model with Energy and Peak Charges

Abstract: SummaryWe describe a model developed to help minimize the energy procurement costs of a New Zealand process industry that is a high user of electricity. The model accounts for stochastic prices that depend on the hydrological state of the electricity system, as well as transmission charges that are incurred during coincident electricity peaks. We describe how these are modelled and derive a stochastic dynamic programming algorithm that is used to arrange production to meet demand while minimizing the expected … Show more

“…Anytime peak pricing can be contrasted with coincident peak pricing (and its relation "time-ofuse" pricing) which imposes a demand charge in periods when the system experiences peak demand (as modeled in [6] for example). The Hopkinson rate was originally intended to charge for electricity when it was primarily used for lighting, and so any user's peak demand typically coincided with the system peak.…”
