Public Service Company of Colorado
Why you’ve been invited here today:
► PUC Rule 3627 – 10 year transmission planning
outreach
►Provide an overview of transmission planning
►Review long-range plans
►Gather “alternative solutions” to proposed
plans for further study and evaluation
►Address alternative solutions in next 10-year
plan
►Every two years
CPUC Rule 3627
► Recently adopted by the Colorado Public Utilities
Commission
► Provide government agencies and other
stakeholders with opportunities for “meaningful
participation”
► Provide summary of stakeholder participation and
input in the plan
► Provide participating stakeholders with filings
related to the rule

Transmission Planning Basics
Stakeholder Participation
How it works
Power is generated
and transmitted over
transmission lines to
distribution lines to
customers. Voltage is
reduced at substations
and electricity is
delivered to customers
Transmission Lines – 345 kV

Planning Principles
► Focus on customer and affordability
► Ensure alignment with policy makers
► Ensure cost recovery support from regulators
► Coordinate with subregional utilities
► Actively participate in regional plan development
► Coordinate with subregional(CCPG) and regional
(WestConnect, WECC) planning groups
Transmission Coordination
Transmission Ownership
Colorado
Economic Planning
► Various resource scenario evaluation
► Economic evaluation of alternatives
► SPSG (Scenario Planning Steering Group) WECC
► TEPPC (Transmission Expansion Planning Policy
Committee) WECC
► Economic benefits, coupled with other benefits
(reliability, local or regional policy, etc.) enter into
transmission alternative evaluation
Balancing Act
Transmission planning
is the art of identifying
future transmission
infrastructure for
delivery from forecasted
resources to forecasted
load centers without
violating mandatory
compliance standards.
Transmission Planning Process
Why Plan?
Planning
Development
Construction
• 1 to 2 years
• 3 to 5 years
• 2 to 3 years
Timeframe takes 7 to 10 years to plan, develop and construct
Transmission Participants in
Colorado Coordinated Planning
Group (CCPG)
Transmission Planning
Drivers
► Core
► Load forecast (April 2010)
► Transmission service studies
► Wholesale/retail load and generation interconnections
► NERC reliability compliance and planning criteria
► Sub Regional
► FERC Generation Interconnection Studies* –8,932 MW, 45 Requests, Wind (24), Solar
(19), Combined Cycle (2)
► State and national energy policy
► State renewable portfolio standards
► 2007 Colorado resource plan -bid solicitation -(PSCo)
► SB -100 transmission plans to energy resource zones (Biennial plan filed Oct. 2007 and
Oct. 2009)
► 10-Year Colorado long range planning group (CCPG) studies (Jan. 2009)
► 10-Year WestConnect Annual Plan
► Regional
► National and State energy policies advocating reduced carbon emissions, renewable
energy portfolios, reliability and operation criteria inherent to intermittent renewable
sources
Senate Bill 07-100
► Upon recommendations by the 2006 Transmission Task Force on
Reliable Electricity Infrastructure, the 66th General Assembly passed
Senate Bill 07-100
► Under SB 07-100, PSCo must meet the following requirements:
► Designate “Energy Resource Zones (ERZ)”
► Develop plans for the construction or expansion of transmission
facilities necessary to deliver electric power consistent with the timing
of the development of beneficial energy resources located in or near
such zones
► Consider how transmission can be provided to encourage local
ownership of renewable energy facilities
► Submit proposed plans, designations, and applications for certificates
of public convenience and necessity to the commission for
simultaneous review
Long-Range Planning Projects
► More than 40 projects for PSCo 10-year plan
►Available on our webpage
►Hardcopy to view here at the workshop
►WestConnect website
► Today’s focus is on specific projects for this region
►Does not include distribution projects or normal
course of business projects
