**[PROPOSED]{.underline}**

## SSG-WI 2015 Case Preparation Process and Schedule

**A. 2015 Cases to be created by SSG-WI**

> The following 2015 cases will be created by SSG-WI

1.  "Do Nothing" case

    a.  case will be developed from the final 2008 case

    b.  Loads - will be extrapolated to 2015 levels

    c.  Resource additions -- Add high cost resource in each area,
        priced to only run if the area is resource deficient.

    d.  Transmission -- No incremental transmission will be added

> 2\. "Planned Resource Scenario" case

a.  Resource additions (2008 to 2015) -- Add resources identified in
    utility IRPs and state Renewable Portfolio Standards, NPCC 5^th^
    Power Plan, CEC resource projections for California, available IRPs
    for NW publics, PNM filing with PRC, and any other documented
    resource plans.

b.  Loads -- WECC forecast for 2015

c.  Transmission -- add only major transmission required to integrate
    above resources.

**B. Process to develop SSG-WI 2015 Cases**

1\. "No Nothing" case -- **Modeling Team** will create this case from
existing 2008 base case.

> 2\. "Planned Resource Scenario" case --
>
> a\. Develop "strawman" matrix with readily available modeling detail,
> for proposed resource additions (2009 to 2015) (Those identified below
> should send information to the Modeling Team who will complete the
> matrix)

-   **CEC** does CA resource additions -- Angela Tangetti

-   **WIEB/LBL** -- IRP data from LBL for Avista, PSE, PGE, PAC, NWE,
    Sierra/NP, Xcel

-   **WIEB** -- PNM filing with PRC

-   **BPA/NPCC** -- NW Publics & NPCC 5^th^ Power Plan

-   **NREL/Modeling Team** -- Add renewables to meet RPS standards

-   **Modeling Team** -- after above is completed, identify resource
    "gaps" by area to meet planning margin

> b\. Obtain information from SPG's to fill in the gaps as needed and
> prepare scenario material for review by SPGs and States -- **Modeling
> Team**
>
> c\. **SPG's and State's** review "strawman" matrix, make revisions and
> **complete the details** missing in the matrix -- SPG Liaisons and
> WIEB submit to Modeling Team.
>
> d\. Refer discrepancies to TSG for resolution
>
> e\. If responses not received on time, go with "strawman"
