A copy of the Company's 2016 Rule 3206 Report, which was filed on May 2, 2016, is enclosed for your information. The purpose of the report is to provide the PUC with an opportunity to determine whether or not specific projects require a Certificate of Public Convenience and Necessity. Interested parties may file comments with the Commission regarding any of the projects listed in the report. Public Service is planning several new electric transmission projects in Weld County to facilitate replacement of the existing 44 kV transmission system, improve reliability, increase the local load serving capability, and accommodate potential generation resources. These projects include: 1. Ault-Cloverly 115 kV line, Graham Creek and Husky substations (also known as North Greeley Area Project). The project consists of two new substations and two new transmission lines. One substation is planned to be located near the town of Ault and the other planned to be located near the town of Eaton. Completion of this project is tentatively scheduled for 2019. 2. Weld-Rosedale 230 kV transmission line, consisting of approximately 13 miles of new 230 kV transmission between the existing Weld substation and the existing Rosedale substation. 3. Milton-Rosedale 230 kV transmission project, consisting of approximately 7 miles of new 230kV transmission between the existing Rosedale substation south of Greeley, and the proposed Milton substation. Together the Weld-Rosedale and Milton-Rosedale Projects are also known as the Southern Greeley Area Project. 4. The Southwest Weld Expansion Project. In 2016, Public Service expects to make a joint filing to the Colorado Public Utilities Commission with Tri-State Generation and Transmission Inc. to participate in their Southwest Weld Expansion Project (SWEP). The SWEP is a plan to initiate transmission development in the region to improve reliability and increase the capability to serve load growth in the area. Portions of the project are planned to be located near Hudson.

STATUS OF PROJECTS LISTED IN PRIOR REPORTS 21 2 Public Service Company of Colorado Transmission Construction Project Name of the project: Southwest Weld Expansion Project Participation Project description: In 2016, Public Service expects to make a joint filing with Tri-State Generation and Transmission Inc. (Tri-State) to participate in their Southwest Weld Expansion Project (SWEP). The Commission granted Tri-State a CPCN in Proceeding No. 14A-0896E and Proceeding 15A- 0728E, Decision Nos. C14-1482 and C15-1135 respectively. The joint filing would seek to amend the Tri-State CPCN to include the Public Service participation in the project. The SWEP is a plan to initiate transmission development in the region to improve reliability and increase the capability to serve load growth in the area. The objectives of participation for Public Service are to provide service for its own customer load growth, align with plans to replace the 44 kV transmission system in and around Greeley, and accommodate new generation resources. The SWEP consists of 230 kV and 115 kV transmission that begins near Ft. Lupton, Colorado, travels east towards Colfer, and then heads north and ultimately connects to the existing transmission a few miles south of Kersey. The project also includes a 230 kV line between Ft. Lupton and Henry Lake substations. Public Service and Tri-State executed an agreement to cooperate in SWEP in November 2014, which provides for Public Service ownership rights for up to 40% of the project. Refer to Attachment A, Exhibit—H from the Tri-State CPCN application filing, for the one-line diagram of this project. Estimated cost of the project: $27 million (Transmission dollars — Public Service share only) Manner in which the project is expected to be financed: Public Service capital budget for Public Service's share of the project Projected date for the start of construction of the project: Under Construction by Tri-State 3 Estimated date of completion of the project: December 2018 Estimated in-service date of the project: December 2018 Proposed general location: The project will be located in Weld County, Colorado.

Project cost will be estimated when an in-service date is determined. 29 Attachment G Bluestone Valley Project Scope Update (item # 22 in Status of Projects Listed in Prior Reports) The original scope of this project consisted of a new Bluestone Valley 230/69 kV Substation. The substation would include a 230/69 kV transformer and would interconnect the existing Parachute - Cameo 230 kV line and the existing DeBeque - Cameo 69 kV line. From Bluestone Valley Substation, a new line would be constructed to a new Grand Valley Power Clear Creek Substation. Public Service has now split this project into two phases: A 69 kV phase and a 230 kV phase of the project. Public Service intends to move forward with the 69 kV portion of the project now. The 230 kV phase may be constructed at a later time based on local load growth. The current plan is to construct a new Bluestone Valley 69 kV Switching Station with associated 69 kV buswork, switches and circuit breaker. The switching station will connect to the existing DeBeque - Cameo 69 kV line by way of a 1.4 mile, in-and-out 69 kV double circuit line. The 69 kV double circuit line will likely use single 477 kcmil ACSR conductor. The project will result in a DeBeque - Bluestone Valley - Cameo 69 kV line. The purpose of the project is to improve the reliability of the local 69 kV transmission system. This phase of the project is estimated to cost approximately $7.2 million dollars. The proposed project will be located near the Town of DeBeque in Mesa County in northwest Colorado. The expected in-service date is June, 2018. The Bluestone Valley Substation project was originally reported in the 2009 Rule 3206 filing. The 2009 filing listed the project as a new 230 kV substation that would interconnect the Rifle (Parachute) — Cameo 230 kV line. The Commission determined that no CPCN was required in Decision No. C09-0681, Proceeding No. 09M-392E. In 2013, Public Service modified the scope to include the 69 kV portion of the project. 30 Hello
