Q0377 December 9, 2011 Page 1 CONFIDENTIAL / DRAFT

1.0 Description of the Project Interconnection Customer is constructing a new generation resource on their system which will interconnect to PacifiCorp’s (Transmission Provider) system at the locations shown in Figure 1. The new Project consists of a 199 MW GE combustion (gas) turbine in the Interconnection Customer’s system. The exhaust heat from this combustion turbine will be directed into a heat recovery steam generator to generate steam to re-power the existing Power Plant Units 1, 2 and 3. The combined output of the combustion turbine and Units 1-3 will be 269.4 MW for summer and 275 MW for winter. The point of interconnection is defined as the point the Interconnection Customer’s conductor attaches to the Transmission Provider’s take off structure located in the protection and control, communication and interchange metering substations which are adjacent to the Interconnection Customer’s substations. The requested commercial operation date for the Project is January 1, 2014. Transmission Provider has assigned the Project Queue “Q0377”. Interconnection Customer has chosen to have the project interconnection as an Energy Resource.

2.0 Scope & Objectives The objective of the facilities study is to:

• Complete a facilities analysis which shall specify and estimate the cost of equipment, engineering, procurement, and construction required to address issues as outlined in the system impact study, and

• Provide a scope of work and an estimated cost and schedule for completing the scope of

work.



3.0 Study Assumptions • All active higher priority transmission service and/or generator interconnection

requests will be considered in this study. If any of these requests are withdrawn, the Transmission Provider reserves the right to restudy this request, as the results and conclusions contained within this study could significantly change.

• For study purposes there are two separate queues: o Transmission Service Queue: to the extent practical, all network upgrades that are

required to accommodate active transmission service requests and are expected to be in-service on or after the Interconnection Customer’s requested in-service date for the Project will be modeled in this study.

o Generation Interconnection Queue: when relevant, interconnection facilities associated with higher queue interconnection requests will be modeled in this study. However, network upgrades required to provide delivery will only be modeled for projects which have requested network resource integration service only or qualified facility status. No generation will be simulated from any higher queued project unless a commitment has been made to obtain transmission service.

• The Interconnection Customer’s request for interconnection service in and of itself

does not convey transmission service.

• This study assumes the Project will be integrated into Transmission Provider’s system at the substations.

• The Interconnection Customer will construct and own the any facilities required

between the point of change of ownership and the Project.

• Generator tripping may be required for certain outages.

• All facilities will meet or exceed the minimum WECC, NERC, and Transmission Provider performance and design standards.

• It is assumed the Interconnection Customer’s proposed two new 138kV lines of

approximately 8.4 miles in length from the new 138kV substation to a new Interconnection Customer owned 138kV substation are in service. It is assumed that OPGW fiber optic cable was installed with the transmission lines. This is modeled in the study.



• It is assumed the GIS substation will be constructed and in service as part of the Interconnection Customer’s scope of work for the Interconnection Customer’s load addition project. It is assumed that a medium D20 RTU with an interposition rack using DNP 3.0 protocol into the multiplex channel was installed with the load project.

• It is assumed any transmission line upgrades beyond the point of interconnection are in service as part of the scope of work for the Interconnection Customer’s load addition project.

• It is assumed the fiber upgrades are in service as part of the scope of work for the

Interconnection Customer’s load addition project.

• It is assumed that the existing 138kV line will be re-terminated making it the Terminal- New substation 138kV line.

• If the assumptions used in this study significantly change, the Transmission Provider

reserves the right to perform a re-study.

4.0 Scope of Work

4.1 Facilities Analysis Results The interconnection of the Q0377 project will require the construction of a small Transmission Provider owned protection and control, communication and interchange metering substation adjacent to the Interconnection Customer’s substations. The Transmission Provider’s scope of work will also include the installation of metering, protection and control and communication equipment at the Interconnection Customer’s existing Power Plant, new generation and new generation facilities. Three existing circuit breakers will need to be replaced at the Transmission Providers Oquirrh substation and communication upgrades will be needed at the Salt Lake City and Portland Communication centers. Approximately ¼ mile of the existing 138kV transmission line will need to be decommissioned at approximately 1800 feet of new 138kv transmission line will need to be constructed to create the new Terminal – new substation transmission line.

The 138KV breaker status can be hard wired over to the substation RTU. If this is not feasible, a small RTU could be installed at the Plant and fiber converters could connect it back to a mux channel at the substation, or the audio might be bridged back to the DNP 3.0 9600 baud leased line that the meters in the refinery substation are using.
