The New England Power Pool Generation Information System (NEPOOL GIS) issues and tracks certificates for all MWh of generation and load produced in the ISO New England control area, as well as imported MWh from adjacent control areas. In addition to the generation, the NEPOOL GIS provides emissions labeling for the New England load-serving entities by tracking the emissions attributes for generators in the region. In recent years the NEPOOL GIS has adapted to the various state RPS laws to track combined heat and power, demand response and conservation and load management certificates.

For information on NEPOOL GIS functions, please reference the NEPOOL GIS Help Center selection in the above menu.
