Base CaseRocky Mountain Area Transmission Study

Presentation to Steering Committee

February 5, 2004

RMATS

Revised inputs

Monitor/enforce constraints on an additional 4 paths• Naughton to Ben Lomand; Yellowtail N and S; Sierra total imports

Modify the way in which 2 additional paths are monitored• Brownlee East and Flaming Gorge to Bonanza• Also increase Brownlee East by 100 MW to 1850<W

Refine schedules for planned maintenance Correct and update certain loads

• Adjust NW load flow data for change in aluminum smelters loads; add upper Missouri loads; zero out the negative loads in SSG-WI data for DC ties to Eastern Interconnect

Calculate average LMPs on seasonal as well as annual basis• January and June months selected

Changes since January 26 Technical Review

3

RMATS

Additional validation

Address discrepancy in COI and Pacific DC duration curves• Model is loading DC less than actual practice• Combine COI and the DC for comparison purposes • Apply nomogram to enforce split of flows between DC and AC

Address discrepancy in TOT 2• Additional info

SCIT duration curve• Examine discrepancy between modeling results and actuals

Compare base case load forecast to WECC forecast Document process and key assumptions for load forecast (in progress

– LFWG) Examine dispatch of thermal units

• Esp. minimum run


4

RMATS

Additional runs

Run “unconstrained” cases for internal RMATS paths only and for top 5 RMATS congested paths only, as well as for all Western Interconnect

A first look: transmission to address congestion in 2008• IPP DC line: Determine change in system-wide variable costs (VOM) if

500 MW capacity is added

• SW Wyoming to Bonanza: Determine change in VOM if line rating is increased by100 MW

• Idaho to Montana: Determine change in VOM if phase shifter added


5

RMATS

Presentational improvements

Further clarify model capabilities and limitations

Clarify certain input and modeling assumptions • For example, wind resource hourly shape assumptions, heat rates not adjusted for

elevations, wheeling charges not included in LMP prices

Enhance contour maps• Expand geographic scope and focus on time periods of greatest congestion

Add certain calculations to slides• Add mean, Std Dev., and correlations to duration curves

Remove net position slides

Further refine formatting of duration curves

Editorial fixes

RMATS

Base Case Observations

In concept, transmission congestion (bottlenecks) and losses cause differences in marginal prices at the nodal/bus level (LMPs)• In this modeling, transmission congestion drives differences in LMPs

LMPs are calculated separately for loads and generation• In the base case, the lowest LMPs for loads are at Laramie River, Colorado-West,

and Yellowtail• Lowest LMPs for generation are at Laramie River, Colorado-West, and Bonanza• Indicates generation is bottled up

LMPs tend to decrease as relatively low cost resources are added• High wind capacity sensitivity is an example

Targeted transmission investments would levelize/stabilize marginal prices because congestion is relieved • Sensitivities were run to explore the change in VOM costs if constraints are

removed – all constraints west-wide, constraints internal to the Rocky Mountain sub-region only, and constraints on Rocky Mountain import/export paths only

• VOM cost savings would be significant and reach broadly• Such savings alone do not justify making investments, however. Investment costs

and other factors must also must be considered

7

RMATS

Base Case Observations

The top 5 congested paths in the Rocky Mountain sub-region are also export-related paths:• Idaho to Montana• TOT 2C• Bridger West• IPP DC• TOT 3

The top 5 congested paths at $4 gas price are also the top 5 at $5 gas price• Dispatch ranking of plants is unchanged• Exception: high wind capacity sensitivity

Analysis includes a first look at opportunity costs (congestion costs) and potential solutions for three of the top 5 congested paths

Next steps: consider other alternative transmission solutions for 2008, determine capital costs, determine technical feasibility

Potential Solution• Increased line rating by 100 MW

(increase line limit to 300 MW from 200MW); this can be accomplished by adding a transformer and possibly line compensation.

Results• System wide cost decreases by ~$4.3

million; hydro model does not allow hydro redispatch.

• Line loading increases by 7,170 MWh

• Alleviates binding congestion, which now occur 3% of the time

RMATS

Next StepsPotential Solutions

Proposed transmission solutions were tested based on VOM cost savings

Capital costs are not considered (TAWG) Power Flow/Stability analysis should be run to

confirm technical feasibility; other solutions should be examined (e.g., FACTS device instead of phase shifters, etc.)

Measured savings apply to the entire Western Interconnect; this raises question about sharing the costs 9

Benchmarking

62

RMATS

The objective is to compare patterns of path loading

Applies to all paths• Added about 1600 MW of resources to the SSG-WI 2008 case

• Compares 2002 actual loads to 2008 base case

• PDCI line flow is less than historic loadings; low load is caused by absence of contractual rights, tariff wheeling and tariff loss charges

Must consider modeling limitations when drawing conclusions
