Generator Information System cost-exemption requests and renewals for 2014 due by November 18

It’s that time of year again for owners of Generation Information System (GIS) Load Assets to request or renew exemptions from GIS Costs charges for the coming year. To request or renew an exemption for 2014 charges, Lead Load Asset Owners must submit a certification or opinion letter along with the GIS Exemption Request Form to by close of business on November 18, 2013.

GIS is an emissions reporting and tracking tool that monitors environmental attributes of generated electricity. For each megawatt-hour of electricity generated by individual units, a certificate is assigned that records the attributes of that power. These certificates are then used by electricity suppliers to differentiate their products for consumers, to provide the information required on energy disclosure labels, and to comply with state and regional Renewable Portfolio Standard and emissions performance standards. GIS Costs represent the expenses incurred by the ISO for the vendor that administers GIS. The methodology for allocating GIS Costs is described in the document, Allocation of Costs Related to Generation Information System.

For a load asset to be exempt from GIS Costs charges, its Lead Load Asset Owner must annually provide ISO New England with either a certification by one of its officers or an opinion of counsel explaining the specific reason, per the state’s Attribute Laws, why each of its load assets is not subject to the GIS Costs charges. Read the GIS Annual Exemption Process Instructions for more detailed information on how to request or renew an exemption status.

Reminder: If a change is made to an assets’ owner during the year, both new and previous GIS Account Holders must inform APX of the change in order for the GIS Costs to be charged to the appropriate party.

Exemption status of each load asset is listed on participants’ Market Information System GIS Costs reports. Any GIS Load Asset with exempt status that is not renewed will become non-exempt effective with the January 2014 metered load’s billing cycle.
