Goals and Expectations
• Goal: Develop a process that allows competitive
generators to deliver their energy to load on a
reliable transmission system.
• Expectations of this stakeholder process:
– An iterative process that examines Tri-State’s
interconnection procedures;
– Constructive dialog with stakeholders on specific
improvements to Tri-State’s concept paper;
– Final procedures that meet the goal.

Background
• In 2007 and 2008, 57 requests were added to
Tri-State’s queue
– Process became unmanageable

LGIP Changes Effective 1/12/09
• Projects designated as a network resource or with
a power purchase agreement receive priority for
study work—FIRST READY-FIRST SERVED.
• Prior to Facilities Study, network interconnection
requestors must have power customer.
• Suspension of construction for Force Majuere
events only.
• Only accept “immediately available funds” in
advance.
• Several changes to streamline study process.

LGIP Reform
• Tri-State’s LGIP Reform concept paper is the
second step in a two step process
• Changes in January were designed to improve
queue management and the interconnection
study process.
• Tri-State’s LGIP Reform concept paper
presents ideas that will simplify and expedite
the generation interconnection process.

LGIP Reform
• Most of the changes adopted in January 2009
will be retained.
• New Concepts:
– Interconnection process based on Load and
Resource Transmission Study.
– New options for determining Network Upgrades.
– Biannual Interconnection Request Windows.

LGIP Reform
• New Concepts (continued):
– Multiple Customer options for proceeding to
Facilities Study
– Queue Management:
• First Come-First Served through the System Impact
Study, subject to priority for projects with
designation as Network Resource;
• First Ready-First Served after the System Impact
Study.

Load and Resource Plan
• Load and Resource Plan
– Submitted by all Network Customers.
– Identify resource amounts and anticipated
geographic areas.
– Up to 4 resource distribution scenarios will be
accepted with each plan.
February 19, 2009
11
Draft Definition
• Load and Resource Plan shall have the
meaning set forth in Section 31.6 of the
Tariff and shall identify projected load
growth and projected amounts of generating
capacity from each Resource Zone to meet
the network integration transmission
customers’ network load requirements.
February 19, 2009
12
Load and Resource
Transmission Study
• Performed once annually
• Will include transmission upgrades in
Tri-State’s most recent 10 year
transmission plan.
• Will determine and estimate the cost of
additional upgrades required to
accommodate the needs presented in the
Load and Resource Plans.
February 19, 2009
13
Draft Definition
• Load and Resource Transmission
Study means a transmission planning
study that models the Transmission
System and identifies Network Upgrades
and projected amounts of generation
from each Resource Zone to
accommodate the combined Load and
Resource Plan.
February 19, 2009
14
Draft Definition
• Resource Zone means a geographic area that is
a projected location for interconnection of new
Network Resources to the Transmission System.
Transmission Provider shall evaluate each
Resource Zone on the basis of the combined
Load and Resource Plan of all Network
Integration Transmission Service customers as
required by Section 31.6 of the Tariff, and in
coordination with Transmission Provider’s
applicable Tariff and regional transmission
planning responsibilities.

Interconnection Service
• Pro Forma LGIP:
– Energy Resource Interconnection Service
– Network Resource Interconnection Service
• Tri-State concept:
– Single Interconnection Service
– Focuses on Interconnection Facilities
– Network Upgrades handled either in Load and
Resource Study or subsequent to Transmission
Service Request (TSR)
February 19, 2009
16
Interconnection Service—Draft
• Interconnection Service. For the purpose of
Interconnection Service, Transmission
Provider shall make no distinction among
types of transmission service or delivery
capabilities from physically similar
Interconnection Facilities, except that
Network Upgrades shall be identified either
through a Load and Resource Transmission
Study or through studies to be provided as part
of a Transmission Service Request.
February 19, 2009
17
Interconnection Service—Draft
• The Product. Transmission Provider shall conduct the
necessary Studies to construct the Interconnection Facilities and
Network Upgrades needed to integrate the Large Generating
Facility (1) in a manner comparable to that in which
Transmission Provider integrates its generating facilities to serve
native load customers based upon a Load and Resource
Transmission Study that includes Network Upgrades; or (2) with
Interconnection Facilities provided and Network Upgrades added
pursuant to a Transmission Service Request; or (3) with
Interconnection Facilities provided and Network Upgrades
deferred at the Interconnection Customer’s own risk of operating
limits for the purpose of future Transmission Service.
