Description: Revision to Protocol Section adds the submittals to ERCOT by affected Entities that are required under the provisions of Protocol Section This change captures as protected information the descriptions of the metering facilities of all Common Switchyards that contain multiple points of interconnection of Loads (ESIDs) and generation meters (EPS). Revisions to Protocol Section add the requirement to include within the Resource Parameters submittal the methodology and, if utilized, the values of constants in any underlying net injection calculation for each Resource. Revision to Protocol Section clarifies that net power output from generation resources may be provided to ERCOT systems as a measured or calculated value. Revisions to Protocol Section, Real-Time Energy Imbalance Payment or Charge at a Resource Node incorporate settlement methodology to be applied in the situation of a net metering installation. Revisions to Protocol Section memorializes the requirement that affected entities provide to ERCOT metering diagrams; and adds the requirement that all Load(s) included in a net metering arrangement for an EPS Metering Facility shall only be electrically connected to the ERCOT grid through the EPS Metering point(s) for such Facility and that these Loads shall not be electrically connected to the ERCOT Grid through electrical connections that are not metered by the EPS metering point(s) for the Facility.
Reason: These changes are required to port the existing net metering provisions of the zonal market to the nodal market implementation. Additionally, these changes clarify that Generation Resource’s must provide net generation output for use by the ERCOT systems.
