Final Five-Minute Reserve Zone Requirements, Prices, and Designations

Download reports for final five-minute reserve zone requirements, designations, and prices. The report includes data for each five-minute interval of the day in the region's four reserve zones. The time listed in each row indicates the start of the interval; for example, 9:15 indicates that the prices and designations are effective from 9:15 until next time new data are published.
 

The reserve zone IDs are as follows: 7000 = Rest of System Reserve Zone (ROS), which is the area excluding the other reserve zones; 7001 = Southwest Connecticut Reserve Zone (SWCT); 7002 = Connecticut Reserve Zone (CT); 7003 = Northeast Massachusetts and Boston Reserve Zone (NEMABSTN).
 

Note: The reserve requirements listed in the reports for 7000 are actually requirements for the whole system.
