Overview
• NERC’s Evolution to Today’s Culture of Compliance
• Organized and Bilateral Markets – No Standard Market Design
• Regional Planning is working and improving
• Interregional Planning in process
• Smart Grid Applications for Transmission in Future
About NERC: Reliability History1965 Northeast Blackout I
1968 NERC formed
1978 National Energy Act – NERC Expands
1980 NERC Merges with NAPSIC
1987 National Electric Security Committee
1992 Energy Policy Act - NERC action plan for the future
1996 FERC orders on open access put NERC on a course to become a self-regulatory reliability organization
1997 NERC/DOE “Blue Ribbon” Panel suggests mandatory standards
2002 First reliability standards become mandatory and enforceable in Ontario
2003 Northeast Blackout II
2005 Energy Policy Act creates “Electric Reliability Organization”
2006 NERC applies & becomes “Electric Reliability Organization”
2007 First reliability standards become mandatory & enforceable in US

Need for Transmission

High levels of variable generation will require significant transmission additions and reinforcements.

Transmission…
• represents only a fraction of a consumers total energy bill (5-10%)
• enables and defines markets
• can no longer be an undervalued asset since it provides tremendous benefits in reducing congestion costs, improving value of diverse/variable resources, enhances grid efficiencies and dynamic performance
• is aging infrastructure in existing ROWs that could provide tremendous value and capability as it is replaced and rightsized, where appropriate

EWITS Scenario 2
Merchant Developers like Clean Line are Proposing Large HVDC Projects
FERC Order 1000US 500 kV and above AC plus HVDC Transmission
25
Future in SPP
• Renewable development beyond member needs of 12GW in SPP will depend on level of exports. While focus to date has been wind, solar will be next, then…
• Asset management with aging infrastructure will be a challenge. Effective use of new and existing ROWs will be key success factor
• Future is bright with more robust planning and certainty of cost allocations, but we need smart grid applications to minimize renewable curtailments in advance of grid build-out and to manage flows using new technology, e.g., HVDC, as well as system reconfiguration/ optimization tools
26
So…where are we going?
• ITP in process, Integrated Marketplace in place 1Q14
• EIPC Federal Futures project >100GW wind in SPP
• Customers have requested dozens of Firm Transmission Service Requests with more than 7GW of wind exports from SPP to SERC, with firm/contingent firm service on adjacent systems. Most under study, with few granted
• SPP reviewing through and out rates which should help potential rightsizing of facilities in a key corridor or two
• Compliance filings for FERC Order 1000 for regional and interregional planning due October 2012 and April 2013, respectively
