End-to-end solutions for utility-scale energy storage.
Energy storage is becoming an increasingly crucial solution for supporting grid reliability, renewable integration and decarbonization goals.
From project development and front-end planning through commissioning, Kiewit offers fully integrated engineering, procurement and construction (EPC) services for utility-scale energy storage projects. Our market diversity allows us to draw from expertise across renewables, power generation, industrial and heavy civil sectors to deliver tailored storage solutions that meet project-specific needs — safely and efficiently.
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 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.
Battery Energy Storage Systems are essential to modern solar infrastructure — increasing system flexibility, enabling energy delivery after sundown, and supporting grid stability. Kiewit provides full EPC solutions for co-located or stand-alone BESS installations across North America.
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.
