6PPA 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)
7Outcome 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

10Current Project Status and Hurdles
11Independent 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
12Regional 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.
13Allocating 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.
14Beginning 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.

16Right-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
17Cost 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
18Issues 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

21Southern California Transmission Projects
22Near 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.
23PUC 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
25PUC 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
26PUC 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
27Federal 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
28Policy 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?
