3. What is the Function of NEPOOL GIS?
Load Serving Entity (LSE)
A system to assist in accumulating data for complying with reporting requirements
Results of the system will be used to generate reports for use by LSE’s 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

4. Development of the GIS Operating Rules
System designed based on NEPOOL GIS Operating Rules.
Collaborative effort in the development process.
