The Markets and Reliability Committee Thursday approved corrections to errors inserted in Schedule 1 of the PJM Operating Agreement and Attachment K of the Tariff in 2008 and 2009.

One correction will clarify how deviations occurring within one zone are associated with PJM’s Eastern or Western region for purposes of Operating Reserve charges.

The other will insert a cross reference to tie language concerning forgiveness of positive demand deviations to the shortage pricing “trigger.”
