METHOD AND SYSTEM FOR INTERMEDIATE TO LONG-TERM FORECASTING OF ELECTRIC PRICES AND ENERGY DEMAND FOR INTEGRATED SUPPLY-SIDE ENERGY PLANNING
First Claim
1. A method of price forecasting in an electrical energy supply network and/or load (energy demand) forecasting of a given consumer of electrical energy, in the context of an electrical energy supply network that is adapted to supply electrical energy to a number consumers connected to the network, for identifying the optimal mix of energy hedge and exposure to day ahead/spot market prices for deriving economic benefits in overall energy expenditure, the method comprising;
- developing a multi-regime, regime switching stochastic model for determining day ahead/spot market energy prices using at least one historical profile and an experts opinion; and
configuring the multiple regimes to correspond to a number of combinations of key physical factors, each regime is identified by at least three factors,wherein a program using a processor unit runs one or more of said developing and configuring steps.

Abstract
A method of price forecasting in an electrical energy supply network and/or load (energy demand) forecasting of a given consumer of electrical energy, in the context of an electrical energy supply network that is adapted to supply electrical energy to a number consumers connected to the network. The method includes developing a multi-regime, regime switching stochastic model for determining day ahead/spot market energy prices using at least one historical profile and subjective opinion from at least one expert; and the multiple regimes correspond to a number of combinations of physical factors. A regime is identifiable by at least three factors. The method thus facilitates identifying the optimal mix of energy hedge and exposure to day ahead/spot market prices for deriving economic benefits in overall energy expenditure.
