United States Power Epc Market: Market Size & Forecast 2026

Power EPC services in the United States encompass engineering design, equipment procurement, and physical construction of power generation projects spanning utility-scale thermal, hydroelectric, nuclear, solar photovoltaic, wind, geothermal, and energy-storage facilities. The market has demonstrated consistent expansion, with 2024 estimates placing it in the $20-29 billion range, reflecting solid demand across conventional and renewable project categories alike. Near-term outlooks project the market approaching the $47-49 billion range by the early 2030s, assuming current policy and investment trajectories hold.

• •Market valued at approximately $30.48 billion in 2026, building on 2024 estimates of roughly $20-29 billion depending on scope and methodology
• •Consensus forecast CAGR of approximately 5.1%, with long-range projections suggesting a market approaching $47-49 billion by the early 2030s
• •Scope covers full-cycle project delivery across conventional generation, renewable installations, transmission infrastructure, and grid-modernization programs

Federal energy and climate policy, including tax-incentive frameworks for qualifying clean-energy technologies, has been a dominant catalyst for EPC activity, spurring investment in new solar, wind, and battery-storage projects across multiple geographies. Rapidly rising electricity demand, driven by manufacturing reshoring, electrification of transport and heating, and the explosive growth of data-center load, has amplified utility capital expenditure and, by extension, EPC contracting. Additionally, the aging profile of existing conventional and nuclear generating assets, combined with state-level renewable portfolio standards, creates a continuous pipeline of repowering, retrofitting, and replacement projects.

• •Federal clean-energy incentive programs have unlocked tens of billions in new project capital, directly converting to EPC contract awards across utility-scale solar, onshore and offshore wind, and grid-scale battery storage
• •Data-center load growth, manufacturing expansion, and building and vehicle electrification are driving demand for new generation and transmission capacity at rates unseen in decades
• •Asset-aging dynamics in conventional generation and nuclear fleets, alongside tightening environmental regulations, sustain a steady stream of retrofit, repowering, and replacement EPC work

The market is commonly segmented by power source, thermal (natural gas, coal, and remaining nuclear projects), renewables (solar, wind, hydro, geothermal), and emerging technologies (battery storage, green hydrogen facilities), each with distinct engineering and construction profiles. Transmission and substation EPC constitutes a growing sub-segment as grid-interconnection queues lengthen and utilities invest in upgrade programs. Geographically, market activity is concentrated in states with aggressive renewable mandates and high load growth, notably the Southwest and Southeast for solar and nuclear, the Great Plains and offshore Atlantic for wind, and the Intermountain West and Texas for large-scale generation and transmission build-out.

• •Renewables (particularly utility-scale solar and onshore wind) represent the fastest-growing EPC sub-segment, with battery-storage and emerging technologies gaining share as system-integration requirements grow
• •Conventional thermal and nuclear EPC remains a significant revenue contributor, driven by long-lead-time capital projects and fleet-replacement needs, though project counts have moderated
• •Market activity is concentrated in high-growth regions: the Southeast and Southwest for solar and new nuclear, the Great Plains and offshore corridors for wind, and Texas and the Intermountain West for transmission-led expansion

Who are the notable companies in the industry?

## Competitive Landscape The U.S. Power EPC sector remains structurally fragmented at the project-entry tier, where mid-sized and specialty contractors compete for smaller renewable and distributed-generation scopes, while a handful of diversified EPC groups self-perform on multi-billion-dollar thermal, nuclear, and integrated renewables-plus-storage programs. **Siemens AG** anchors the field with deep technology integration and a strong digital-solutions foundation aimed at streamlining energy-service development, while **Fluor Corporation** leverages an extensive, cross-sector project portfolio to engage in large-scale energy projects and innovative engineering solutions, increasingly through local-partner collaborations. **Bechtel Corporation** brings a global reach and comprehensive project-management expertise to large-scale energy-infrastructure construction, with its strategy centered on energy-transition programs. **John Wood Group PLC** contributes broad service offerings for energy and utilities clients, applying technology-driven approaches to support energy transition and operational efficiency. **JGC Holdings Corporation**, along with affiliated **JGC Corporation**, draws on long-standing EPC expertise in energy and industrial markets, including oil and gas specialization, while expanding capabilities into renewables to capture shifting project pipelines. **Mitsubishi Heavy Industries, Ltd.** and **McDermott International Ltd.** further extend competitive depth through heavy-industrial engineering and large-scale energy-project execution, reinforcing the upper tier of capable contractors.

• •Market spans from a small number of large, vertically integrated EPC contractors with broad power-sector capabilities to a broad base of mid-tier and specialty firms focused on specific technologies or project tiers
• •Dominant project-delivery routes include traditional lump-sum turnkey contracts for large thermal and nuclear projects, and EPC or design-build arrangements for utility-scale renewable and energy-storage installations
• •Regional capacity concentration aligns with project pipelines: thermal and nuclear capability is concentrated near existing generation hubs in the Midwest, Southeast, and Gulf Coast, while renewable and transmission EPC capacity has expanded into the Southwest, Intermountain West, Great Plains, and Atlantic seaboard

What are the recent trends and outlook?

The near- and medium-term outlook for the U.S. Power EPC market is underpinned by structural rather than cyclical demand drivers, with load growth and policy support providing visibility well into the 2030s. Repowering of older renewable sites, replacing turbines or solar inverters and upgrading balance-of-systems, represents an emerging contract category as first-generation assets reach the end of their initial operational cycles. The integration of large-scale battery storage as a co-located or stand-alone asset class is creating new EPC workflows that combine civil, electrical, and commissioning disciplines in novel configurations. Supply-chain considerations, including equipment lead times, skilled-labor availability, and permitting timelines, remain the primary near-term constraints on project execution and, consequently, revenue recognition for EPC operators.

• •Repowering of first-generation solar and wind assets is emerging as a significant EPC opportunity as installed renewable fleets age and technology improvements justify component and layout upgrades
• •Co-location and hybridization of generation with grid-scale battery storage and emerging clean-energy technologies are expanding the scope and complexity of power EPC project scopes
• •Supply-chain pressures, equipment procurement timelines, skilled craft labor availability, and interconnection and environmental permitting throughput, are the key near-term factors that could moderate project delivery rates and revenue timing across the sector
