Summary
The Minimum Current Exposure (MCE) calculation, which is part of the Total Potential Exposure (TPE) credit evaluation, fails to recognize net purchases of firm physical power, which is a crucial and widely utilized means to fulfill Load serving obligations. Not recognizing net purchases of firm physical power causes the MCE to inaccurately overstate the actual credit risk posed to the market and unfairly penalizes Market Participants who prudently hedge their Load positions.
