Detailed Description

Off peak power index.

A commodity index to represent daily off-peak power prices.

In general, when used in derivatives the off-peak power value for a given date will be:

1. the average of Locational Marginal Prices (LMPs) over the off-peak hours, generally 8, on peak calendar business days
2. the average of LMPs over all hours on peak calendar holidays

There are generally two types of daily futures in the power markets:

1. those that average the LMPs over the peak hours, generally 16, on every calendar day
2. those that average the LMPs over the off-peak hours, generally 8, on every calendar day

This off peak power index uses the prices of both of these daily future contracts to construct the index that is used in derivatives that reference off-peak power prices. The off-peak future is used directly on peak calendar business days. On peak calendar holidays, the weighted average of the daily off-peak future price and daily peak future price is used where the weights are the number of off-peak hours and peak hours respectively divided by 24.

pastFixing()

Real pastFixing ( const Date & fixingDate ) const

overrideprotectedvirtual

returns a past fixing at the given date

the date passed as arguments must be the actual calendar date of the fixing; no settlement days must be used.
