A Message from PJM:
The changes in the Data Viewer application related to Dynamic Reserves that was reviewed at the July 18th Tech Change Forum is now available. Data provided on the new Dispatched Reserves page is based on the real-time security constrained economic dispatch solution, which solves for a near-term look-ahead interval. Reserve pricing, and declaration of shortage pricing, is based upon the data displayed on this page. The existing Operating Reserves page has been updated with more descriptive labels, whereby the Reliability Synchronized Reserves Requirement represents 100% of the output of the single largest online contingency in the Reserve Zone or Sub-zone and the Reliability Primary Reserves Requirement represents 150% of the output of the single largest online contingency in the Reserve Zone or Sub-zone. Additional information on the reserve requirements can be found in Manual 11, Section 4.2.2.
