PPA Structure/Project Financing/Transmission
  • PPA Structures are typically volumetric energy
    based
  • Project revenues entirely dependent on energy
    deliveries to the grid
  • Physical congestion that results in curtailment
    of energy reduces project revenues
  • Financing entities are very sensitive to risk to
    project revenues
  • If project bears curtailment risks, it needs to
    be bounded
  • Pressure for Firm Transmission/Network Service
    (or Full Delivery in CA markets) as congestion
    mitigation
  • Firm Transmission/Full Delivery Service
  • Involves the engineering analysis of boundary, or
    extreme, conditions
  • Presumption that if transmission capacity is
    available under the boundary condition(s), then
    Available Transmission Capacity (ATC) exists
  • If ATC is not available under the boundary
    condition(s), little information is generated to
    quantify the extent of the deficiency
  • Transmission Upgrades are identified, potentially
    involving large, expensive new lines in order to
    satisfy the boundary conditions (and the
    financing parties)

7
Outcome of Current PPA Transmission Practices
  • Underutilized Transmission Assets
  • Boundary conditions seldom, if ever, experienced
  • 25 (/-) capacity factor resource vs 24x7
    transmission
  • Unclear Justification for Large Investments in
    New Transmission Facilities
  • Cost versus value assessment is not comprehensive
    and is dispersed in the LSE procurement processes
  • Few tools available for risk management if the
    value/cost ratio is low
  • Tools such as Conditional Firm Transmission have
    nominal value when the risk/financing question is
    not addressed.
  • Long Delay and Great Uncertainty in Renewable
    Generation Development
  • 7-10 year lead time for major new transmission
    lines.
  • Many renewable generation projects cannot sustain
    such delays
  • Path 46 (West of River) Rating - 10,623 MW
  • Path 49 (East of River) Rating - 9,300 MW

Current Project Status and Hurdles
11
Independent Transmission Barriers
  • Planning, Permitting, Cost Recovery
  • RTO Practices and the Right of First Refusal
  • Transmission Interconnection Process
  • Regulatory Wish List Level Playing Field
  • Project evaluation, approval, and cost recovery
    or
  • Competitive process after planning is complete

12
Regional Transmission Planning Prerequisite to
a Robust Renewable Energy Supply VERS Balancing
  • The need for Southwestern planning and
    coordination has never been greater. Renewable
    integration and balancing demands interlinking
    Southwestern load with renewable resources.
  • 2001-2005 STEP (Southwest Transmission Expansion
    Plan)
  • By 2007, STEP was to be succeeded by a CAISO-led
    sub-regional planning group
  • In 2008, SCE convened a Pacific Southwest
    Planning Association (PSPA)
  • In 2009, PSPA was overtaken by the California
    Transmission Planning Group (CTPG)
  • DOE/WECC transmission planning process is taking
    broad view of overall transmission plan
  • Currently, there is no forum for working out
    cooperative approaches to transmission planning ,
    permitting, cost allocation and operation
    specific to the Southwestern states.

13
Allocating Cost to Ratepayer and Renewable
Energy Advantage
  • FERC Order 2003
  • Financing burden intended to provide incentives
    for efficient transmission use and lessen need
    for new transmission by influencing generator
    siting- not anticipating location-constrained
    renewable resources in remote locations.
  • Texas SB 20 Approach
  • Texas approach provides for lines to Competitive
    Renewable Energy Zones (CREZs).
  • Southwest Solution Promote Interstate Flow of
    Renewable Energy, Enhancing Reliability
    Reducing Overall Cost
  • Without a cost allocation solution, pancaking
    will deter southwest solar development and create
    a barrier to the lowest-cost, reliable renewables
    infrastructure.

14
Beginning this important journey with a few sure
steps
  • Ultimately, we need a comprehensive, robust
    Southwestern transmission web.
  • This journey will never reach its destination
    unless we begin with some concrete steps
    immediately.
  • Joint nomination of pilot projects by any two
    states would provide sufficient lines for a proof
    of concept, with planning and permitting
    completed to commence construction in 2013.
  • With demonstrated progress, mid- and longer-term
    planning is more likely to achieve results- and
    maintain renewables investment.

16
Right-Sizing Transmission Lines
  • Double-Circuit vs. Single-Circuit Lines
  • Double-circuit more expensive but more
    cost-effective, when fully utilized
  • Optimal use of ROW
  • Install the second circuit when needed
  • Path rating limitations
  • Who pays how do they recover their costs?
  • Cost allocation
  • Cost recovery

Double-Circuit Structures
Single-Circuit Structures
17
Cost Allocation/Recovery for HPX
  • Cost allocation doesnt apply for non-RTO regions
    that dominate WECC
  • Voluntary agreements for cost-sharing
  • Investments typically justified for serving load
    for reliability
  • How to fund to meet public policy goals?
  • Who pays for right-sizing?
  • How to assure cost recovery?
  • HPX PacifiCorp-Gateway Dilemma
  • Double vs. single-circuit 500 kV
  • Matching need with cost over time

600 mile 500 kV example, based on WREZ model
18
Issues to be Addressed by State Regulators
  • Cost recovery to meet need public policy goals
  • Nothing gets built without the assurance of cost
    recovery
  • How to assure cost recovery in non-RTO regions
    for non-jurisdictionals?
  • Right-sizing to optimize land use future demand
  • Potential solution socialize the incremental
    costs for the 2nd circuit
  • Regional cooperation between states
  • Clarity in public policy siting, permitting,
    RPS cost recovery
  • Without the foregoing..
  • Some renewable projects will continue to be sited
    in sub-optimal locations to the detriment of
    consumer costs renewable development
  • Incremental transmission expansion will be the
    norm...to the detriment of land use optimization
    where economies of scale are forgone

Company Overview
  • Structure
  • Solar Trust of America (STA) joint venture
    of Solar Millennium AG and MAN Ferrostaal AG.
  • 75 years of EPC market experience 25 years of
    solar thermal experience.
  • Solar Millennium, LLC is wholly owned subsidiary
    of Solar Trust of America.
  • Development Projects
  • Developed and built first parabolic trough
    plants in Spain (Andasol) 13 plants, total 150
    MWs, with 7.5 hours of molten salt storage.
  • 30 MW Solar field integrated into 150 MW CCGT
    plant in Egypt (under construction).
  • More than 2,000 MWs currently in development in
    the U.S. Southwest.

21
Southern California Transmission Projects
22
Near Term CA Transmission Enhancements
  • Up to 5000 MW of new transfer capacity from the
    Colorado River to California load centers could
    be available in the near term.
  • Each of the new projects comprising this capacity
    has essentially been through the planning,
    siting, permitting, cost allocation, approval
    hurdles, however none are completely cleared for
    construction.
  • In addition, roughly 2500 MW of new transfer
    capacity should become available over the next
    eight years as California phases out coal imports
    in compliance with SB 1368.
  • The focused attention of state/federal policy
    makers is required to allow the bulk of this
    potential new transmission capacity to be made
    available to renewable energy projects to achieve
    state/regional renewable energy generation
    targets.

PUC Policies and Development of RTPs in the West
Southwest Renewable Energy Transmission
Conference
Tom Wray Project Manager
May 21, 2010
24
  • 470 miles
  • Two 500 kV lines five substations
  • AZ and NM 14-county study area

25
PUC Missions are Similarfor Regulating
Electricity Supply
  • AZ need for an adequate, economical and
    reliable supply of electric power
  • CA safe, reliable utility service and
    infrastructure at reasonable rates promote
    competitive markets
  • CO safe, reliable, and reasonably-priced
    services consistent with the economic,
    environmental and social values of our state
  • NM reasonable and adequate services
  • NV reliable service at rates that are just and
    reasonable
  • UT reliable, adequate, and reasonably priced
    utility service

26
PUC Policies Affect RTP Development
  • Renewables are remotely located in the West
  • New long-distance EHV RTPs are needed
  • RTP investors need assurances that
  • Competitive interstate wholesale supply markets
    exist
  • Regulatory impediments to utility supply choices
    do not exist
  • Not all proposed RTPs will be permitted
  • Resulting in a scarce supply of deliverable
    renewable energy from remote sources

27
Federal Preemption is likely
  • National policy of more renewable energy
    requires significant capital for RTP development
    on the grid
  • SENR is considering a national RPS
  • FERC is requesting siting authority for
    interstate EHV lines
  • Some state procurement policies disregard
    benefits of higher capacity factors and lower
    delivered prices in favor of in-state renewable
    generation resources
  • Procurement policies favoring in-state
    generators are eliminating incentives for
    investment in RTPs across the western grid

28
Policy Topics for Panel
  • How can PUC regulatory procurement policy be
    coordinated to reduce interference with
    interstate commerce of renewable energy?
  • How is economical electricity provided to
    customers by reducing wholesale competition
    across state lines?
  • What is better than the market for allocating
    scarce commodities?
