Abstract

A system, method, software, and portfolios for managing risk in markets relating to a commodity delivered over a network are described, in which a market participant constructs portfolios of preferably liquid price risk instruments in proportions that eliminate the Spatial Price Risk for the market participant'"'"'s underlying position. Techniques are also disclosed for constructing and evaluating new price risk instruments and other sets of positions, as well as identifying arbitrage opportunities in those markets.

Claims

1. A method for hedging a set of underlying positions at a prospective time in a market related to a commodity delivered over an electric power network, comprising the steps of:

using a computer for estimating a plurality of distribution factors indicating effects on one or more congestible lines in the electric power network due to transfers of the commodity at respective locations in the electric power network; and

using a computer for producing a portfolio of price risk instruments for the market based on the estimated distribution factors,

wherein the step of producing the portfolio includes selecting a portfolio y of price risk instruments, such that z′

A−

y′

P′

A=0, where A represents the distribution factors, P represents the available market of price instruments, z represents the underlying position, and the ′

(prime) symbol denotes a transpose of a matrix.

2. A method for identifying arbitrage opportunities among a plurality of available price risk instruments in a market related to a commodity delivered over an electric power network, comprising the steps of:

using a computer for estimating a plurality of distribution factors indicating effects on one or more congestible lines in the electric power network due to transfers of the commodity at respective locations in the electric power network; and

using a computer for producing a portfolio of price risk instruments from among the available price risk instruments based on the estimated distribution factors, wherein a number of the price risk instruments is greater than a number of the one or more congestible lines,

wherein the step of producing the portfolio includes selecting a portfolio y of price risk instruments, such that y′

P′

A=0, where A represents the distribution factors, P represents the available market of price instruments, and the ′

(prime) symbol denotes a transpose of a matrix.
