Public Service Company of Colorado on July 31 filed with the Colorado Public Utilities Commission a quarterly construction progress report for the Cheyenne Ridge Wind Project, noting that as of June 30, Public Service has spent $685m, or 92%, of the “baseline budget” for the project of $743m.
The company noted that under the terms of an approved settlement, the point cost for project capital costs is $743m, including allowance for funds used during construction (AFUDC), with $743m referred to in the quarterly reports for the project as the “baseline budget.”
As noted in the filing, the commission in April 2019 issued a decision approving a certificate of public convenience and necessity (CPCN) for the project, which is comprised of the approximately 500-MW Cheyenne Ridge Wind Farm and the approximately 65-mile, 345-kV generation tie-line (Gen-Tie) necessary to connect the wind farm to the Rush Creek Gen-Tie and Public Service’s system.
The company said that as detailed in its first quarterly report for the project filed in October 2019, all major contracts have been awarded and executed.
Key construction activities that occurred during 2Q20 include that the:
- Wind turbine generator (WTG) blade deliveries and erection were completed; WTG pre-commissioning activities continued; WTG final commissioning started
- Construction of the underground collection system was completed
- Construction of the West and East collector stations were completed and both stations were energized
- Site restoration activities continued
- The Gen-Tie was energized
The company added that as of June 30, the construction progress is estimated as such: blade deliveries, collection system, and turbine erection — 100% complete; pre-commissioning — 86% complete; and final commissioning — 44% complete.
Public Service said that as detailed in its quarterly report filed on April 30, it, its construction partners, and crews have been complying with corporate policies and guidance from the Centers for Disease Control and Prevention (CDC) to ensure a safe work environment during the COVID-19 pandemic. To date, the company said, there have been no significant COVID-19 associated impacts or delays to the project schedule.
The overall project continues to progress ahead of schedule and is currently tracking to meet the December commercial operation date (COD), Public Service said.
Among other things, the company said that its efforts to reduce project costs are ongoing, with cost savings captured in 2Q20 by a reduction in estimated road repair costs due to implementation of continuous maintenance throughout the project, as well as a reduction in estimated wind delays due to deploying night shift construction labor during the windy season.
