In response to member feedback, PJM has improved the way public information, such as historic locational marginal pricing data, is made available through pjm.com. The new Data Miner tool provides a new method for requesting specific public data through the website as well as a method for making system-to-system requests (via Web Services). This enhancement enables stakeholders to request public data over a date range of their choosing, as well as for specific pnodes, and allows this data to be downloaded in formats that are easier to analyze and manage (.csv, .xml). While this new application provides extended capability for the user, the existing methods and formats for retrieving public data from pjm.com have not been affected.
