Abstract

A method for hedging energy sales or purchases in a short-term future or day-ahead market includes determining an historical performance of a regional net energy forecasting methodology for a facility or facilities which have solar energy generating systems in a geographical region. The method further includes estimating a difference between the maximum cost of energy in a spot market and an energy trader'"'"'s minimum price of energy for each hour bid in the short-term future or day-ahead market, determining a risk factor associated with energy sales or purchases from the historical performance and the estimated difference, and purchasing or selling options to buy energy at the previous day'"'"'s day-ahead market price based on the determined risk factor.

Claims

1. A method for hedging energy sales or purchases in a one day-ahead, short-term market against shortfalls in a spot market, comprising:

determining on a computer processor an historical accuracy of a regional net energy forecasting methodology for a facility or facilities which have solar energy generating systems in a geographical region;

estimating a difference between the maximum cost of energy in a spot market and an energy trader'"'"'s price of energy for each hour during a forward spot market;

determining a risk factor associated with energy sales and purchases from the determined historical performance and the estimated difference between the maximum cost of energy and the energy trader'"'"'s price of energy; and

purchasing options based on the determined risk.

2. A method for hedging energy sales or purchases in a short-term future or day-ahead market, the method comprising:

determining on a computer processor an historical accuracy of a regional net energy forecasting methodology for a facility or facilities which have solar energy generating systems in a geographical region;

estimating a difference between the maximum cost of energy in a spot market and an energy trader'"'"'s minimum price of energy for each hour bid in the short-term future or day-ahead market;

determining a risk factor associated with energy sales or purchases from the determined historical performance and the estimated difference; and

purchasing or selling options to buy energy at the previous day'"'"'s day-ahead market price based on the determined risk factor.
