PowerP&L provides data in four perspectives

  • Day-Ahead shadow settlement data 
  • Real-Time shadow settlement data ( updated every five-minutes )
  • Day-After shadow settlement data
  • Final Settlement/Bill Module


Data is updated as frequently as every five minutes and includes day-ahead and real-time LMP, energy and ancillary service revenues, costs and margins. Estimated Operating Reserves and Credits as well as performance measures such as lost opportunity revenues are also calculated.

This provides a powerful tool for real-time analysis and decision making as well as a tool for review of historical data. The tool also provides lost profit analysis for each hour due to various reasons such as inability to follow dispatch, outages, etc. The key goal is to understand periods where profit is not maximized, so that companies can best evaluate internal processes to capture lost margin and maximize profits.

All of the financial data analysis using known and forecast market data, internal data, and costs are rolled up along with the shadow Profit and Loss and presented real-time. Along with our core metrics, the system is designed to allow addition of client specific metrics that are critical to each unit or fleet.
