The Peak Market Activity (PMA) credit requirement is used to establish a baseline credit requirement for each member, using historical activity as a guide. Virtual Transactions (INC/DEC/Up-to transactions) are financial instruments with their own bid screening system. Export transactions will also have their own credit screening system. This proposal would exclude from PMA the spot market energy, transmission congestion and transmission loss charges (and negative charges) that result from Virtual Transactions as well as export transactions.
