PJM May Have Overpaid Generators By Up To $15 Million
May 07,2015
PJM said in a market notice yesterday that it recently identified that for at least the past 24 months, some Market Sellers have been erroneously credited with Lost Opportunity Costs (“LOC”) due to the provision of incorrect or inconsistent generator availability information to PJM.
PJM credited these Market Sellers with LOC during hours in which their generation resources cleared in the Day-ahead Energy Market but were unavailable to operate in real-time because the Market Sellers did not indicate in eMKT that their resources were on a forced outage during the Operating Day in question. Generation resources that are on forced outages in real-time are not eligible to receive LOC credits.
PJM estimates that the total amount of LOC payments to all affected Market Sellers since April 2013 that might be subject to billing adjustments is no more than $15 million in total.
As PJM refines its estimates of these billing adjustments in the coming weeks, PJM will reach out to individually affected Market Sellers with further information related to the precise amount of LOC for which they were improperly credited, and will issue billing adjustments to these Market Sellers in accordance with section 10.4 of the PJM Tariff.
