Definitions

  • the present invention broadly relates to a method or system for trading in a commodity.
  • the present invention relates to trading in commodities with a time variable demand and cannot be stored, such as electricity.
  • Electricity is typically provided to end users via electricity retailers. Any given wholesale electricity market typically involves a number of electricity generators, retailers and traders. As is the case with most commodities the price of electricity varies depending on the supply/ demand ratio.
  • Uniform load reflects a constant load quantity throughout the different time intervals of a trading period whereas variable load reflects changeable load quantities for the different time intervals throughout a given trading period.
  • Uniform load electricity pricing typically involves: an average price for all time intervals within a specified trading period; an average price for all peak time intervals within a specified trading period; or an average price for all off-peak time intervals within a specified trading period. These forms of uniform load electricity trading are known as flat, peak and off-peak respectively.
  • Variable load pricing of electricity typically involves specific time intervals of work and/or non-work days.
  • the cost of electricity for each time interval is calculated by multiplying the load quantity of electricity during that interval by the market price of electricity per unit during that interval.
  • the cost of electricity for the trading period is typically based on the sum of the costs for each specific time interval of the trading period.
  • the average price of electricity during any given trading period is typically calculated by dividing the cost for the trading period by the total load quantity during the trading period. The resulting average price is referred to as the load weighted average price.
  • Wholesale electricity trading may involve an intermediary in the form of a broker and / or an exchange. These intermediaries typically facilitate trade between electricity generators, retailers and traders. However, because of the complicated manner in which variable load pricing is calculated and the individuality of variable load requirements by participants, the intermediaries typically only facilitate trade involving uniform load pricing. As the demand for electricity may vary greatly throughout any given 24-hour period it may be typically difficult for market participants to execute a trade or trades of a desired load profile.
  • a method of trading a commodity comprising the steps of: determining a variable commodity demand; assigning a reference uniform demand to the commodity demand, said reference uniform demand being equal to or greater than the maximum value of the variable commodity demand; deriving a residual commodity demand by comparison of the reference uniform demand and the variable commodity demand; and calculating a price for: the variable commodity demand; or the residual commodity demand; or the reference uniform demand.
  • x is, or is representative of, the variable commodity demand
  • y is, or is representative of, the residual commodity demand
  • z is, or is representative of, the reference uniform demand
  • a is a price for the variable commodity demand
  • b is a price for the residual commodity demand
  • c is a price for the reference uniform demand.
  • the above step may be repeated for the creation of multiple variable commodity demands of different structure.
  • variable commodity demand varies over a predetermined time period.
  • a second aspect of the present invention there is provided a method of an intermediary facilitating trade between a buyer and a seller in the variable commodity demand and/or the residual commodity demand as calculated in the first aspect of the invention.
  • the method of the second aspect involves the intermediary obtaining bids and/or offers from market participants which result in a trade in the variable commodity demand and/or the residual commodity demand.
  • a system for trading a commodity comprising: data input means for inputting data defining a variable commodity demand, and a reference uniform demand corresponding to the variable demand; data processing means in communication with the data input means and configured for processing the input data; and data output means in communication with the data processing means and configured for outputting a residual commodity demand.
  • the data processing means of the third aspect of the present invention is preferably arranged to derive the residual commodity demand in accordance with the method described above.
  • the method also comprises the step of defining the variable commodity demand.
  • the variable commodity demand is preferably defined by a series of three or more discrete commodity demand values, which correspond to specific time intervals within the predetermined time period.
  • the variable commodity demand may be defined by a series of inputs representing the relative value of the variable commodity demand against the reference uniform demand for each specific time interval within the predetermined time period.
  • the reference uniform demand may be assigned a value of 1 and the variable commodity demand being defined by the relative proportion for each specific time interval within the predetermined time period.
  • the reference uniform demand is preferably equal to a maximum value of the variable commodity demand during the predetermined time period. However, the reference uniform demand may also be greater than the maximum value of the variable commodity demand.
  • the residual commodity demand is preferably derived by subtracting each specific time interval of the variable commodity demand from the corresponding specific time interval of the reference uniform demand over the predetermined time period.
  • the method also comprises the step of facilitating trading in the commodity.
  • the method preferably further comprises the step of the intermediary facilitating trading in the commodity for the variable commodity demand, or the residual commodity demand or both the variable commodity demand and residual commodity demand.
  • variable commodity demand or the residual commodity demand is one of a plurality of variable commodity demands.
  • the present invention at least in its preferred form creates tradeable parcels of variable load electricity.

  • a market price for each interval is ascertained (column 3) and then multiplied by the load per interval (column 2) to provide a "Load x Price" per interval (column 4).
