What is the Function of NEPOOL GIS?

• Load Serving Entity (LSE)
• A system to assist in accumulating data for
  complying with reporting requirements

  reports for use by LSEs and regulatory agencies.
• Generation
• An accounting system of generation attributes for
  energy consumed in NE to be reflected on a
  Certificate issued to the owner of the asset.
• Traders
• A common platform that tangibly identifies
  generation attributes
• Regulatory Agencies
• Consistent Reporting
• Conservation of generation attributes
