Platte Valley Voltage Conversion The objective of the Platte Valley Voltage Conversion Project is to convert the operating voltage of the 34. 5 k. V transmission lines and related facilities between Lingle Substation and Sievers Rural Substation to 69 k. V. The lines were rebuilt in the early 90’s to 69 -k. V standard.
Platte Valley Voltage Conversion The majority of the work is converting the numerous substations and taps along the line segments to 69 -k. V. Western and Tri-State signed a Letter of Concurrence in November 2004 laying the initial scope and responsibilities for the upgrades.
Platte Valley Voltage Conversion Scope: Lingle Substation: Install a 115/69 -k. V 40 MVA transformer and associated equipment. Torrington Substation: Install a 69/34. 5 -k. V 50 MVA transformer and associated equipment. Sievers Rural Tap: Install a 69/34. 5 -k. V 25 MVA transformer and associated equipment. Construct eleven miles of new 69 -k. V line between East Morrill Tap and Sievers Rural Tap.
Platte Valley Voltage Conversion Scope (cont): Torrington Rural Tap: Replace transformer and rebuild high side for 69 -k. V. Henry Tap: Replace transformer and rebuild high side for 69 -k. V. Village of Morrill Tap: Make necessary modifications to operate existing dual winding transformer at 69 -k. V. Connect the Town of Lingle Tap to the Limestone-Lingle 34. 5 -k. V line.
Platte Valley Voltage Conversion Scope (cont): Estimated Cost: $21 M Planned ISD: FY 2015 Project Manager: Roy Gearhart Current Status: Not planned to start until FY 2012. System Studies updated every two years. System Studies planned for 2010.
Platte Valley Voltage Conversion Major Milestones to date Various System Studies: 2000 -2010 Meeting with Platte Valley Customers: April 2003 Western and Tri-State signed Ltr of Concurrence: November 2004 Meeting with Platte Valley Customers: April 2005 Meeting with Platte Valley Customers: April 2007 Published Platte Valley Voltage Conversion Project Overview: January 23, 2006
Platte Valley Voltage Conversion Lingle Substation Scope: 115 k. V/69 k. V 40 MVA transformer with high and low side interrupters for protection. New Substation site required for 115/69 k. V additions New Control Building Schedule: 2012 -2015 Estimate: $4, 730 k (In 2014 $’s)
Platte Valley Voltage Conversion Lingle Town Scope: Move connection to Limestone 34. 5 -k. V line with ~0. 5 mile of new 34. 5 -k. V line. Schedule: 2012 -2015 Estimate: $100 k - $200 k (no detail estimate done)
Platte Valley Voltage Conversion Torrington Rural Scope: Convert to 69 -k. V with a 69 k. V/12. 47 k. V 5 MVA and a 69 k. V/24. 9 k. V 7. 5 MVA transformers and 69 k. V improvements on high side. Schedule: 2012 -2015 Estimate: $1, 500 k (In 2014 $’s)
Platte Valley Voltage Conversion Torrington Substation Scope: New 69 -k. V yard with 4– 69 k. V bays; 69 k. V/34. 5 k. V 50 MVA Transformer; New Control Building; more land. Schedule: 2012 -2015 Estimate: $5, 400 k (In 2014 $’s)
Platte Valley Voltage Conversion Henry Scope: Convert to 69 -k. V with a 69 k. V/12. 47 k. V 7. 5 MVA transformer and 69 k. V improvements on high side. Schedule: 2012 -2015 Estimate: $900 k (In 2014 $’s)
Platte Valley Voltage Conversion Village of Morrill Scope: Convert to 69 -k. V high side winding on existing 34. 5/69/7. 2/12. 47 k. V 2. 5 MVA transformer and 69 k. V improvements on high side. Schedule: 2012 -2015 Estimate: No estimate done
Platte Valley Voltage Conversion East Morrill Tap – Wildcat 69 -k. V line Scope: Construct ~3 miles of new 69 -k. V line from East Morrill tap to Wildcat. Creates the Lyman-Wildcat 34. 5 -k. V line. Allows Village of Lyman and Lyman Rural loads to remain 34. 5 -k. V Schedule: 2012 -2015 Estimate: $1, 395 k (in 2012 $’s)
Platte Valley Voltage Conversion Wildcat Substation Scope: No new additions initially planned at Wildcat. Should the system needs change, the new Torrington-Sievers Rural 69 -k. V line could be interconnected with the 34. 5 -k. V system at Wildcat to provide system reliability improvements.
Platte Valley Voltage Conversion Wildcat-Sievers Rural 69 -k. V line Scope: Construct a new 10 mile 69 -k. V line between Wildcat and Sievers Rural to bypass Mitchell area. Bypasses City of Mitchell and Mitchell Rural loads, leaving them at 34. 5 -k. V Schedule: 2012 -2015 Estimate: $4, 045 K
Platte Valley Voltage Conversion Sievers Rural Scope: 69/34. 5 k. V 20 MVA transformer with high and low side protection; new control building; land. Sievers Rural load remains served at 34. 5 -k. V. Schedule: 2012 -2015 Estimate: $2, 250 k (In 2014 $’s)
