Douglas County PUD

Douglas-Rapids 230-kV Transmission Line

Supplemental Progress Report

March 14, 2014

Updated Information from Initial Progress Report

1. Douglas County PUD is constructing a new 13-mile, 230-kV transmission line to connect its

Douglas Switchyard with its Rapids Switchyard. The conductor will be 1590 ACSR/TW and is

expected to have a Summer rating of 589.5 MVA, a Winter rating of 766.8 MVA, an Autumn

rating of 687.9 MVA, and a Spring rating of 671.6 MVA. A new 230/115-kV transformer will be

installed at Rapids Switchyard with expected ratings of 200 MVA (ONAN) 55° C, 266 MVA (ONAF)

55° C, 333 MVA (ONAF) 55° C, and 373 MVA (ONAF) 65° C. The new 230-kV circuit breakers at

Douglas Switchyard and Rapids Switchyard will be rated for 3000 A of continuous current. The

new 230-kV breaker disconnect switches at Douglas Switchyard will be rated for 3000 A of

continuous current and the 230-kV line disconnect switches at Douglas Switchyard and Rapids

Switchyard will be rated for 2000 A of continuous current.

2. The new transmission line is planned to be in operation in April, 2014.

3. The project is currently under construction and is tentatively scheduled for completion in April,

2014. The transmission line is complete, and the remaining work is to finish installing the

transformer at Rapids Switchyard.

4. The facility owner’s name is Douglas County PUD (DOPD). The contact for the project is:

Updated Information from Comprehensive Progress Report

1. See above updated information from the Initial Progress Report.

2. There are no changes to the original one-line and geographic diagrams.

3. A model of the new facility is available in the WECC power flow and stability programs.

mailto:[email protected]

4. The Transfer Capability associated with the project will be equal to the System Operating Limit

(SOL), which is based on the Facility Ratings (MVA ratings at the applicable ambient

temperature) of all applicable Facilities. The WECC Comprehensive Project Coordination Review

process suggests that project sponsors can use Subregional Planning Groups to meet its

requirements (“a project sponsor may use TEPPC or a Subregional Planning Group to meet the

requirements of Project Coordination Review in lieu of forming an independent PCRG for their

project.” Douglas PUD is a member of and uses ColumbiaGrid to accomplish its subregional

planning requirements. The ColumbiaGrid planning process has open participation in its general

planning and study team meetings. The Douglas-Rapids project has been reviewed by and has

achieved consensus through this planning process, which included all of the transmission

owners that could be impacted by this project. Project reports are available from ColumbiaGrid

at http://www.columbiagrid.org. The requirements of Project Coordination Review for this

project have been met through the ColumbiaGrid Subregional Planning Group. The impact of

the Douglas-Rapids project on other systems and on existing transfer path ratings has been

studied in the ColumbiaGrid Northern Mid-C Study Group. Douglas PUD complies with all NERC

Reliability Standards and WECC Criteria. The Douglas-Rapids Line facility additions and planned

system operation are in conformance with NERC Standards and WECC System Performance

Criteria. The Douglas-Rapids project will not require obtaining an accepted transmission path

rating.

5. The proposed Transfer Capability rating is based on Douglas PUD’s System Operating Limits.

Douglas PUD’s System Operating Limits are based solely on its Facility Ratings, which, for

transmission circuits and transformers, are determined by ambient temperature conditions.

6. See studies conducted in ColumbiaGrid Northern Mid-C Study Team and Northern Mid-C Joint

Operational Study Team for operating conditions that allow the project to operate within the

guidelines defined in the NERC Reliability Standards and WECC Criteria.

simultaneous ratings and simultaneous path interactions.

8. To demonstrate Douglas PUD’s compliance with NERC Reliability Standards and WECC Criteria,

the following power flow and stability cases were run by ColumbiaGrid:

a. Summer, 2012

b. Summer, 2013

c. Summer, 2014

d. Summer, 2015

e. Summer, 2019

f. Winter, 2019

To demonstrate Douglas PUD’s compliance with NERC Reliability Standards and WECC Criteria,

the following power flow and stability cases were run by Douglas PUD in 2013:

a. Heavy Summer, 2015

b. Heavy Summer, 2019

c. Heavy Winter, 2019

d. Light Autumn, 2022

e. Heavy Summer, 2023

f. Heavy Winter, 2024

9. In addition to the data provided in the Comprehensive Study Report, See Appendix A for power

flow outage results that demonstrate Douglas PUD’s compliance with NERC Reliability Standards

and WECC Criteria.

10. The project is currently under construction and is scheduled for completion in April, 2014. The

transmission line is complete, and the remaining work is to finish installing the transformer at

Rapids Switchyard. This will be accomplished within the next month.

Rapids-Columbia 230-kV Transmission Line

Supplemental Progress Report

March 14, 2014

Updated Information from Initial Progress Report

1. Douglas County PUD is constructing a new 230-kV transmission line to connect its Rapids

Switchyard with BPA’s Columbia Substation. The conductor will be 1590 ACSR/TW and is

expected to have a Summer rating of 589.5 MVA, a Winter rating of 769.2 MVA, an Autumn

rating of 690.3 MVA, and a Spring rating of 671.2 MVA. The new 230-kV circuit breaker at

Rapids Switchyard will be rated for 3000 A of continuous current. The new 230-kV line

disconnect switch at Rapids Switchyard will be rated for 2000 A of continuous current.

2. The new transmission line is planned to be in operation in January, 2017.

3. The project is currently in the planning and design process. Alternative line routes are being

studied and considered and biological and cultural studies are currently underway. The project

is tentatively scheduled for completion in January, 2017.
