teppc spsg activities5
TEPPC - SPSG Activities

      • Consumer advocate
      • New technology
      • Renewable integration
      • Environmental
      • Tribal

teppc spsg activities6
TEPPC SPSG Activities
  • RFP’s
    • SPSG Technical Support RFP (AWARDED)

      • Energy Planning Analysis (ICF)
      • Energy Policy Analysis (E3)

teppc spsg activities7
TEPPC SPSG Activities
  • SPSG Environmental Data Task Force (EDTF)
    • SPSG, through EDTF, is developing recommendations for a methodology to incorporate environmental data into transmission planning process.
    • Interview with ICF International on 2/21 to share how we incorporate environmental data in SWAT.
    • I need your help – How do we (SWAT) incorporate environmental data into transmission planning?
    • Who else has been contacted?
  • What is “environmental data”?
    • Land, wildlife, cultural, historical, water resources
  • How/when do we bring environmental data into the planning process?
    • Developers? Utilities? Governments?? Others??
teppc spsg activities8
TEPPC SPSG Activities
  • A Sampling of the Interview Questions:
    • “What is it about the planning process that could be improved to facilitate the development of transmission (in general or from an environmental perspective)?”
    • “What assumptions are made in the transmission planning process related to environmental issues?”
    • “Please describe the nature and extent of environmental considerations in IRP processes.”
    • “What types of environmental info does your planning process consider?”
    • “How do we define “environmental data”? Land ownership? Air emissions? Policy?”
    • “How can we use the environmental data to assist transmission development (as opposed to being an obstacle)?”
teppc spsg the scenarios
TEPPC SPSG - the SCENARIOS
  • The DRAFT Scenarios Proposed to be investigated 20 year):
    • Scenario 1 – Brave new world or green ascendant
    • Scenario 2 – Shifting Sands or Riding the Waves
    • Scenario 3 – Lost Years or the Abyss
    • Scenario 4 – Energy Stockade, Fortress USA, Energy Island USA
teppc spsg the scenarios10
TEPPC SPSG - the SCENARIOS
  • Scenario 1 – Brave New World or Green Ascendant
    • Expects climate change regulation through:
        • Taxes
        • Carbon redux goals
        • State vs federal mandates
    • Closure of 90% of coal plants, enacted carbon tax, cheap gas and renewable deployment increase
    • High adoption of alt-fuel vehicles, energy efficiency
    • Technology improvements to lower carbon footprint, smart homes, grid, distributed generation vs large centralized plants
    • Transmission lines needed to harness remote resources for load and meet RPS standards
teppc spsg the scenarios11
TEPPC SPSG - the SCENARIOS
  • Scenario 2 – Shifting Sands or Riding the Waves
    • Anticipates no clear policy or direction
      • Periods of activity, followed by laissez faire, vacillating government policies, lack of clarity at federal, state, local levels
      • Federal Cap and Trade is proposed to be passed, international agreement to reduce carbon emissions
    • Coal plants are moderately affected, some closure, but less environmental (EPA) focus
    • Renewables and Natural Gas are fuels of choice, California policy of all in-state renewables stalls development of mountain-state renewables
    • Transmission development difficult in early years, easier in later years to access renewables, smart grid, dynamic pricing opportunities
teppc spsg the scenarios12
TEPPC SPSG - the SCENARIOS
  • Scenario 3 – Lost Years or the Abyss
    • National/international financial crises stall any significant climate change, energy, or transmission policy. Water crises emerge.
      • Subsidies to fossil fuels and renewables are eliminated
      • Low oil/gas prices, low demand in early years, some price volatility.
    • Climate change legislation abandoned to address the basic needs of food/water
    • Limited EPA regulations on coal, minimal coal retirements. Federal regulations on water impact generation development, eliminates OTC
    • Limited transmission development in early years, modest additions to meet California loads with out of state solar/wind
teppc spsg the scenarios13
TEPPC SPSG - the SCENARIOS
  • Scenario 4 – Energy Stockade, Fortress USA, Energy Island USA
    • International geopolitical instability and huge trade imbalance results in a self-sufficient US energy policy
      • Reduced oil imports (Canada exempt)
      • Alternatives to gasoline engines encouraged by a bridging tax on all gas engines
      • Federal government agnostic on power plant fuels as long as they are domestic fuels – natural gas and renewables are favored
    • Energy independence mandates result in energy efficiency, conservation, technology, and building standards.
    • DG encouraged to reduce vulnerability of transmission system.
    • Self-sufficiency and US isolationismdue to international instability result in economic stagnation and very little transmission development.
    • The limited amount of transmission developed is in response to security (cyber attack/terrorism) concerns and to meet CA loads and RPS standards.
teppc spsg the scenarios14
TEPPC SPSG - the SCENARIOS
  • The scenario descriptions are available at:

http://www.wecc.biz/committees/BOD/TEPPC/SPSG/Shared%20Documents/Forms/AllItems.aspx?RootFolder=%2fcommittees%2fBOD%2fTEPPC%2fSPSG%2fShared%20Documents%2fScenario%20Planning&FolderCTID=&View=%7bAFB30CAC%2dC89C%2d43B8%2dAB4A%2d3AFB9A253FDE%7d

  • How do these scenarios translate into transmission, studies, and a report for 2013?
    • More to come!
scg activities16
SCG Activities
  • SCG = Subregional Coordination Group
  • Eight planning entities

(CTPG still to be added, making 9)

  • Developed Foundational

& Potential Projects list

  • Foundational Projects used in determining the base transmission in the 2020 production cost modeling studies
  • Potential Projects may be used to relieve congestion
scg activities17
SCG Activities
  • January 2011 meeting
    • Technical Study of the 2020 Reference case
      • Round-trip of powerflow-promod-powerflow case
      • SCG’s to determine season/hour of interest to study (SEE NEXT SLIDE)
      • SCG’s to help develop N-1 (select N-2) outages to be studied
      • Consultant will be hired to perform the study work by 2/28
    • “Reasons for Building New Transmission” whitepaper
      • Trying to highlight/educate that there are more reasons to build transmission than just production cost modeling
      • May bediscussed at the February 23-25 SPSG/TEPPC meetings
    • Improving SPG’s coordination and interaction
      • Beginning to formalize SPG coordination to ensure that projects don’t get missed
    • Developing “Planning Projects in the West” informational paper regarding transmission planning in the West
      • Educate on process, groups involved, deliverables
scg activities18
SCG Activities
  • The Round-Trip N-1 analysis – Hours tentatively selected for SWAT footprint
    • Reminder: 2020 transmission topography, Foundational Projects in service, running n-1 and perhaps selected n-2 contingencies
    • What other hours of the 2020 case are of interest?
scg activities19
SCG Activities
  • Plot of March 15, 2020 showing load and load net renewables in the 24-hour period. Hour 12 shows the largest “delta” between plots.
