Project Overview
Mortenson is building a gigawatt-scale renewable energy and storage facility in the Southwest that integrates more than 1,200 MW of solar and wind generation with 2,000+ MWh of battery storage to support a large data center. Combining clean energy, power delivery and complex infrastructure, the project demonstrates an innovative model for meeting growing energy demand sustainably.
Key Takeaways:
- 500+ MW of solar energy
- 750+ MW of wind energy
- 1,000+ MW / 2,000+ MWh of energy storage
- Five substations and 35 miles of transmission line
- Roughly 160 miles of permanent road work to support short- and long-term transportation needs including bypass roads, retaining walls, highway deceleration and turn lanes
- Installation of a 500-foot, three-span bridge to serve as a vital access route for site traffic that provides safe, reliable passage for project operations and personnel
- Roughly 70 miles of temporary road work for safe navigation of construction equipment and personnel
- Roughly 1.8 million cubic yards of grading
- Temporary and permanent hydrology infrastructure
- Soil preparation and stabilization work to ready site for all construction activities
- Proper restoration of all temporary features to minimize impact
- Fire prevention practices (fire break roads, regular mowing and strategic water resource planning)
- Site readiness of five substations, O&M buildings, the transmission line, and solar, wind and data center facilities
- Estimated Completion Date

Meeting Growing Energy Demand while Advancing Clean Energy at Scale
Mortenson is the full Engineering, Procurement and Construction (EPC) contractor for 1,200+ megawatts combined of solar and wind energy generation along with more than 2,000 megawatt-hours of battery energy storage being built in conjunction with a large-scale data center project in the southwestern United States.
By seamlessly combining industrial facility construction with massive renewable generation, we are solving the modern world’s greatest challenge: meeting growing energy demand while advancing clean energy at scale. It’s a different way of thinking, one that our customers and the world both need more than ever.
Innovation in Action
This project is unique in the industry both due to its overall size and the integration of multiple clean energy sources alongside data center construction. That requires detailed planning and consistent communication among the Mortenson team to ensure work is completed efficiently and safely.
The clean energy facility will feature 1.3 million First Solar Series 7 solar panels and Nextpower Hail Pro-75 trackers, along with 112 Vestas 4.5 MW V163 wind turbines, which will consistently maximize power output. An energy storage system will store the power when it is generated and discharge it when it is needed.
Powered by People
At its peak, the project will employ upwards of 4,000 skilled craft workers and 300 non-craft team members from 10 different Mortenson operating groups. The project brings together Mortenson’s expertise in different areas such as wind and solar energy generation, energy storage, power delivery, civil, commercial construction, engineering services, supply chain, and manufacturing.
This cross-functional team will be rooted in the principles of Mortenson’s culture — Do the Right Thing, We Before Me and Inspire What’s Possible — to effectively work together and deliver a successful project outcome.
A detailed schedule will keep the project and all craft team members on track, with scope start and end dates lined up strategically throughout the construction process.
We’re uniquely positioned — both in the work that we do and how we do it — to tackle something of this complexity and size and to handle challenges that go along with it. It’s another way Mortenson is leaning into smart growth for the future.
Building our Energy Future
Through an integrated, cross-functional approach, the Mortenson team is delivering clean wind and solar energy to help meet growing demand from both the commercial and residential sectors. By seamlessly combining data center construction with massive renewable generation, the cutting-edge project offers a blueprint for the future of global infrastructure.
Mortenson is uniquely positioned, both in the work that we do and how we do it, to tackle something of this complexity and size and to handle challenges that go along with it. We are creating value, solving complex challenges, and enabling our customers’ most ambitious visions through unmatched integrated capabilities. That integrated delivery model allowed early coordination to bridge the gap between competing timelines – allowing the project to meet the customer's needs.
Work is expected to be completed in 2028.
