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

Development of the GIS Operating Rules

• System designed based on NEPOOL GIS Operating

Rules.

• Collaborative effort in the development process.

• Rules were adopted by NEPOOL - 1/18/02

• Future changes through NEPOOL Markets

Committee.
