Delivering engineering and construction certainty in renewables.
As demand for clean, reliable power grows, utility-scale solar has become essential to supporting long-term energy needs. Backed by 40 years of proven experience, Kiewit partners with clients to execute complex solar and BESS projects across North America. Our team provides engineering, procurement and construction (EPC) services for utility-scale solar developments, ranging in size from 2 MW to over 1 GW — including co-located and stand-alone battery energy storage, substations and interconnect scope.
Kiewit self-performs design, fabrication and installation using our extensive resources and equipment. Our solar teams have the experience and tools to execute all critical-path activities with a focus on quality, safety, cost certainty and reduced risk.
Designed by Kiewit, ADAPT automates layout and design for large-scale solar facilities. The software enables rapid generation of 90% layouts and key quantities in under an hour, allowing for iterative testing and timely design adjustments to optimize project outcomes throughout the lifecycle.
Kiewit leverages UAV and infrared (IR) inspection technologies to support solar quality control. These tools identify defects that affect solar performance and ensure constructability and cost certainty are integrated into our QA/QC approach.
We support clients at every stage from pre-FEED through commissioning by providing owner’s engineering, project development, layout optimization, systems integration and constructability-focused design. Whether it’s a single task order or a major program, our engineering services are tailored to deliver quality, efficiency and value.
With over $10 billion in annual procurement across a network of 22,000+ vendors, Kiewit leverages global partnerships to provide efficient, end-to-end material management, securing volume discounts and long-term agreements to help clients manage risk and control costs.
Backed by nearly 140 years of construction experience, Kiewit’s integrated engineering and construction teams deliver simplified, cost-effective execution for complex EPC and design-build solar and storage projects. This collaborative approach minimizes delays, reduces cost overruns and ensures that each project meets quality and safety expectations.
Successful projects begin with the end in mind. From turnkey EPC projects to projects for an existing facility, we leverage integrated construction and commissioning teams to provide a seamless transition from construction to commercial operations — safely and on schedule.
Kiewit delivers large-scale BESS and long-duration energy storage projects that enhance grid reliability, integrate renewable energy and keep power flowing when it’s needed most. From engineering through commissioning, our proven EPC expertise ensures safe, efficient, on-time delivery of complex storage solutions.
Beyond Kiewit’s full-service EPC delivery, our construction-focused engineering and consulting services team delivers expertise across various power generation markets.
Our team of 4,000 engineering and design staff, including 1,500 dedicated to power, design and plan projects with a strong focus on constructability. Our clients can expect safe and reliable solutions focused on lower operational costs, reduced downtime and simplified maintenance. Kiewit’s engineering services are designed to meet each client’s specific needs, providing quality, efficiency and value for every project, from small tasks to major engineering programs.
