What is the minimum frequency for updating measurement data in the PJM system?

The minimum frequency for updating measurement data in the PJM system is every 30 minutes. This timeframe is crucial for maintaining accurate and timely information about the electrical grid's operational status, including load and generation levels. Updating data at this interval allows PJM to effectively monitor system performance, respond to operational changes, and ensure reliability across the grid. By obtaining current data every 30 minutes, PJM can more accurately manage resources, forecast demand, and coordinate generation and transmission to meet the needs of the market while maintaining system stability.
