@Domain
public class Buyer
extends Genco

This is a simple buyer that provides some amount of market liquidity, as well as a modest amount of volatility, to the wholesale market. It does this by offering to buy some quantity at some price in each timeslot. The price offered is distributed exponentially around a mean that should be lower than the lowest genco offer price. The quantity requested is inversely proportional to the price.
