## 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.  Run with no transmission or generation resource additions beyond
        2008 case

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

    e.  Transmission -- No incremental transmission will be added

> 2\. "Planned Resource Scenario" case

a.  Resource additions (2008 to 2015) -- Add resources identified in
    utility IRPs, NPCC 5^th^ Power Plan and other approved resource
    plans. Add renewables as necessary to meet RPSs. Perform L&R, set a
    target planning margin, and fill any gaps with thermal units.

b.  Loads -- WECC forecast for 2015

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

d.  This case would made available to others for evaluating resource and
    transmission scenarios

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

1\. "No Nothing" case -- Load Forecasting group will develop 2015 load
forecast. **Modeling Team** will then run.

> 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 complete the matrix and submit to the GSG for review,
> reconciliation, and iteration. Only after all detail is obtained will
> matrices be provided to modeling team)

-   **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 & NWPCC 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 (GSG)
>
> c\. Prepare scenario material for review by SPGs and States --
> **Modeling Team**
>
> c\. **SPGs and State/Provinces** review "strawman" matrix, make
> revisions and **complete the details** missing in the matrix -- GSG
> submits to Modeling Team.
>
> d\. Refer discrepancies to TSG for resolution
>
> e\. If responses not received on time, go with "strawman"
