• Nebraska Wind Conference
• Wednesday, November 16, 2011

Overview

• Nebraska Only public power state
• Nebraska Southwest Power Pool (SPP)
• Nebraska Transmission Advocacy Group (NTAG)
• NTAG Transmission Expansion Plan

3
The Only State

• Nebraska is a totally public power state
• Authority to set rates resides with the
  utility/municipality governing body
• No state legislation mandating renewable
  generation
• NPPD and OPPD Boards have established goals of
  10 renewable generation by 2020
• Nebraska passed legislation in 2010 to encourage
  private developers to
• Develop, own and operate renewable energy
  facilities for export to other states
• Requires utilities to work with the developer on
  a joint transmission development agreement
• Provides a process for the developer to seek
  regulatory approval from the Nebraska Power
  Review Board

Nebraska Southwest Power Pool

• Nebraskas largest utilities (LES, NPPD OPPD)
  joined SPP in 2009
• SPP RTO has members in 9 states and provides for
• Reliability Coordination
• Market Operations
• Tariff Administration
• Transmission Expansion

5
SPP Integrated Transmission Planning (ITP) Process

• ITP goals
• Integrating reliability, economic public policy
  inputs to create a regional transmission
  expansion plan
• Develop plans that are robust, flexible, and
  cost-effective
• Three phases of the iterative process
• ITP20 20 Year Plan (visionary)
• ITP10 10 Year Plan (detail)
• Near-term Conducted yearly (closer to action)

6
SPP Notices to Construct (NTC)

As of 2010, SPP Board has issued NTCs to direct
Transmission Owners to begin construction of
these projects.

Nebraska Transmission Advocacy Group (NTAG)

• A volunteer advocacy group created to proactively
  communicate Nebraskas unified message regarding
  long range transmission expansion to the
  Southwest Power Pool (SPP)
• Led by Nebraska Transmission Owners who serve as
  technical advisors
• Includes representation from NE Utilities, NE
  State government, Wind Energy Coalition NE land
  owners
• Nebraska Power Association (NPA) Board approved
  formation of NTAG

9
Nebraska Conceptual Overlay

• At direction from NTAG, Transmission Planners
  from the Nebraska Sub-regional Planning Group
  developed a conceptual overlay to submit to the
  SPP for the 10-year plan (ITP10)
• Participants
• OPPD, NPPD, LES, MEAN, Tri-State, Grand Island
  Hastings Utilities
• Developed two alternatives for consideration
• r-Plan
• T-Plan

• The combination of the Balanced Portfolio, the
  Priority Projects, and the suggested NTAG
  r-Plan will address all six existing NE
  Flowgates

• The western leg from Cherry County to Stegall
  (substation) will be a subject of discussion at a
  later time for the next 20-year plan (ITP20) to
  be drafted in 2013.

Benefits of NTAG r Plan

• Reduces transmission congestion
• Enhance and improve reliability and robustness of
  the bulk transmission system in the region
• Facilitate tapping into Nebraskas abundant wind
  generation
