2009 State of the Market Report
Virtual supply was generally more profitable at the nodal level ($2.46 per MWh) because larger price differences occur at individual nodes that are less liquid than Cinergy Hub. Almost $36 million of the $41 million in gross virtual supply profits in 2009 occurred at individual nodes, although the allocation of RSG costs offsets more than one-half of these profits. Virtual demand was consistently unprofitable at the Cinergy Hub and generally profitable at other locations. However, many of the demand bids at Cinergy are likely physical hedges (which tend to be modestly unprofitable), rather than speculative bids by virtual-only participants. The average loss of cleared virtual-demand bids at the Cinergy Hub was $0.87 per MWh in 2009, compared to a profit of $0.44 per MWh at nodal locations.
