   Project-specific research

   The current operator project page reports approximately 3,550 MW and a $5 billion estimated cost for the wind power plant. This is the wind-project estimate, not the separate TransWest transmission cost. Physical project infrastructure construction is documented in the operator progress pages.

   Published project-specific cost for Chokecherry and Sierra Madre: USD 5e+09. Basis: Published project-specific capital/construction estimate. Published electric generating project rating for Chokecherry and Sierra Madre: 3550 MW. Basis: Operator-reported electric generating capacity; not annual energy production. The developer describes Chokecherry and Sierra Madre as an approximately 3,550 MW wind project in Carbon County, Wyoming, with major federal and state permits secured and construction underway. This is the planned full-project capacity; it is not operating output.

   The purpose page also lists a $5 billion estimated wind-project cost.

   Scope and evidence

   Retained only with documented physical construction, commissioning or 2025–2026 opening and published project-specific costs and electrical output. Costs use the published scope and currency; no benchmark estimates or currency conversions. MW is power capacity, not annual electricity production. Expected annual energy, where given, is a forecast. The map point is a reported plant/project location and may be approximate. Matching inventory views and excluded expansion proposals are not additive capacity.

   Operator and regulator research, October 11, 2026

   The developer describes Chokecherry and Sierra Madre as an approximately 3,550 MW wind project in Carbon County, Wyoming, with major federal and state permits secured and construction underway. This is the planned full-project capacity; it is not operating output.

   The operator timeline distinguishes road construction beginning in 2016 from subsequent turbine development.

   Earlier pin evidence / inventory snapshot

   August 2026 inventory status

   EIA August 2026 generator inventory, plant ID 58987: Chokecherry and Sierra Madre Wind, Carbon County, WY. Included 4 new/recent generating units with a summed nameplate rating of 3550.5 MW.

   • Generator I-A: Onshore Wind Turbine; 844.2 MW nameplate; summer rating 844.2 MW; (U) Under construction, less than or equal to 50 percent complete; planned operation 2031-12.
   • Generator I-B: Onshore Wind Turbine; 849.6 MW nameplate; summer rating 849.6 MW; (U) Under construction, less than or equal to 50 percent complete; planned operation 2031-12.
   • Generator II-A: Onshore Wind Turbine; 1303.2 MW nameplate; summer rating 1303.2 MW; (U) Under construction, less than or equal to 50 percent complete; planned operation 2032-12.
   • Generator II-B: Onshore Wind Turbine; 553.5 MW nameplate; summer rating 553.5 MW; (U) Under construction, less than or equal to 50 percent complete; planned operation 2033-12.

   Date and location

   EIA reports operation at month/year precision. The date is the last day of the earliest reported operation month/year, an estimated display boundary, not an exact opening day. Different units may have later dates. Future dates are operator-reported plans, not guarantees.

   Coordinates are the EIA-reported plant point, not a verified entrance. New units at existing plants are included; the total excludes older units and battery/pumped storage. Capacity is a power rating, not annual energy output. Status was reported in August and may have changed since.
