Clarify Information Policy re sharing Operating Reliability Data - Meeting #1

Information Policy Changes

Overview

• Background

• The Interregional Security Network (ISN)

• Information Policy Changes

• Transition of NERCnet to the EIDSN

2

Background

Mandatory reliability standards and other FERC/NERC initiatives have pushed for:

•Improved “situational awareness”

•Better understanding of impact of “external contingencies”

•Availability of more detailed information for wide area monitoring

August 2003 Northeast Blackout

•U.S.-Canada Power System Outage Task Force

Sept. 2011 CA/AZ Outages

•FERC/NERC Staff Report on the September 8, 2011 Blackout

The Interregional Security Network (ISN)

• The Interregional Security Network (ISN) is commonly referred to by the term NERCnet and has been in operation since 1997

• NERCnet is a communication network used by NERC, Reliability Coordinators (RCs), Transmission Operators (TOPs), Balancing Authorities (BAs) to share real-time operating reliability data (ORD) across the Eastern Interconnection

• The ORD is used to provide wide area situational awareness and sharing of ORD is a requirement of the mandatory NERC Reliability Standards

• The ORD consists of transmission interface limits, line flows, circuit breaker status , generator output etc.– Likely to include phasor measurement data (PMU) in the near future

Information Policy Changes

• The ISO proposes changes to the ISO New England Information Policy so that the policy better reflects the ISO’s obligations to share reliability-related data pursuant to NERC and similar requirements

Example Reference NERC standards

• http://www.nerc.net/standardsreports/standardssummary.aspx

• COM-001-1.1

• TOP-005-2a

Transition of NERCnet to EIDSN

• NERC has moved to transition management and support of the reliability tools (RCIS, NERCnet, IDC) to the industry

• The “Eastern” Reliability Coordinators are establishing the Eastern Interconnection Data Sharing Network (EIDSN) and management entity to pick up NERCnet

• NERCnet is scheduled to become the EIDSN in 2014
