Executive Summary

USD 207.2 Billion in 2025, the Power EPC Market is expected to grow at a CAGR of 4.4% to reach USD 320 Billion by 2035. Contract award follows FID: EPC scopes are not released until a project reaches final investment decision, and FID timing itself now hinges on a signed power purchase agreement with a creditworthy offtaker.

Grid interconnection reform and transmission capacity expansion are the primary growth mechanisms. FERC Order No. 827 mandates dynamic reactive power compliance for new US interconnections, and the wider FERC Order 2023 interconnection reform is cutting the queue processing delays that had stalled EPC award; US Inflation Reduction Act tax credits are pulling FID forward on both generation projects and the transmission built to connect them. India’s National Electricity Plan targets 6.48 lakh ckm of transmission by 2032. In the EU, Green Deal and REPowerEU targets are lifting auction-driven award volume even as EU Emissions Trading System carbon costs and the incoming CBAM raise input costs for steel- and cement-intensive EPC scopes.

Asia-Pacific led power generation EPC with a 59.40% share in 2025, while South America is the fastest-growing region at a 7.50% CAGR through 2031; Construction commands the largest service-type share at 39.20%. IEA and BNEF data both point to falling LCOE and rising capacity factor as part of the mechanism behind that award volume.

Interconnection queue congestion, which FERC and NERC data show has deferred roughly 60 GW of US capacity into 2027-2028, is the binding constraint on delivery timelines; ENTSO-E’s queue data point to a comparable pattern across European connections. National capacity targets set under the Paris Agreement NDCs continue to underwrite the long-run pipeline, but the Power EPC Market stays fragmented, with regional and mid-tier contractors competing alongside global engineering majors.

Market Definition and Scope

The Power EPC Market covers engineering, procurement and construction services delivered under single- or multi-contract structures for power generation, transmission and distribution assets, spanning greenfield, brownfield and turnkey project types across solar PV, wind, gas turbine, hydro, nuclear and storage technologies, serving utility, independent power producer and industrial offtakers from feasibility through commissioning.

Excluded are standalone equipment manufacturing without installation scope, pure O&M contracts on operating assets, and behind-the-meter residential solar sales that fall outside utility-scale and C&I EPC contracting.

Market Trends

SF6-Free Switchgear Mandates Are Forcing a Substation Retrofit Cycle

The EU’s F-gas Regulation (EU) 2024/573, in force since February 2024 as part of the EU Green Deal and REPowerEU decarbonisation push, restricts placing SF6-insulated switchgear on the market, pushing utilities toward fluoronitrile and clean-air gas-insulated substations. Grid operators replacing medium- and high-voltage bays cannot simply swap components; the transition requires re-engineered bus layouts and protection schemes, work that sits with EPC firms rather than OEMs alone. ENTSO-E’s ten-year network development plans already assume the fluoronitrile transition as a baseline for new interconnectors, and offshore wind capacity awarded through national Contracts for Difference (CfD) auctions increasingly specifies SF6-free equipment as a condition of grid connection. CBAM’s phased levy on imported steel and aluminium adds a further cost variable to bus-layout re-engineering, while a tightening EU Emissions Trading System carbon price raises the cost of deferring the swap. Brownfield substation contracts across EU transmission networks expand through 2035 as the mandatory technology-substitution cycle works through the installed base.

Grid Interconnection Reform Is Redirecting EPC Scope Toward Reactive Compensation

FERC Order No. 827 requires newly interconnecting wind, solar and storage generators to hold dynamic reactive power capability between 0.95 leading and 0.95 lagging at the point of measurement. The requirement lands on top of FERC Order 2023’s interconnection reform, which clusters new applicants and pulls reactive-compensation studies earlier into the queue. Developers taking FID can no longer treat reactive compensation as optional collector-substation equipment; EPC contracts signed against PPA offtake now carry dedicated engineering and procurement scope for static var compensators and reactive banks. That equipment adds fixed capex developers fold into LCOE rather than capacity factor, which reactive compensation does not affect. The requirement applies across every FERC-jurisdictional interconnection, raising per-project EPC content for utility-scale solar and storage builds queued for the remainder of the forecast period.

India’s Statutory Transmission Plan Is Setting a Decade-Long Conductor Tender Pipeline

The Central Electricity Authority’s National Electricity Plan, Volume II, commits India to expanding its transmission network from 5.09 lakh circuit kilometres in June 2026 to 6.48 lakh ckm by 2032, sized to evacuate 500 GW of non-fossil capacity by 2030, the target underpinning India’s Paris Agreement NDC commitment and tracked in both the IEA’s and BNEF’s annual capacity-addition outlooks. The build-out converts a policy target into a fixed multi-year tender calendar for overhead conductor and substation EPC packages. South Asian contractors absorb the bulk of this demand as state transmission utilities release annual tender tranches through 2032.

Growth Drivers and Restraints

FERC’s Reactive-Power and Queue-Reform Orders Are Expanding US EPC Scope

FERC Order No. 827 requires every newly interconnecting non-synchronous generator in FERC-jurisdictional territory to deliver dynamic reactive power between 0.95 leading and 0.95 lagging, forcing US renewable developers to add static var compensation and control-system engineering to collector-substation EPC packages. That requirement now sits on top of FERC Order No. 2023’s interconnection reform, which replaced first-come, first-served queue processing with a cluster-study model and pushes reactive-compliance and deliverability testing earlier into the project timeline, ahead of the developer’s own final investment decision. In South Asia, the Central Electricity Authority’s National Electricity Plan, Volume II, commits India to lifting its transmission network from 5.09 lakh ckm in June 2026 to 6.48 lakh ckm by 2032 and transformation capacity to 2,345 GVA, converting sanctioned targets into a recurring conductor and substation tender calendar that state transmission utilities release annually.

EU Switchgear and Rooftop Solar Mandates Sit Inside a Wider REPowerEU Compliance Calendar

The EU’s F-gas Regulation (EU) 2024/573, in force since 20 February 2024, restricts new SF6-insulated switchgear, obliging utilities to replace medium- and high-voltage substation bays with clean-air alternatives on a rolling basis that EPC firms, not equipment OEMs, execute on site. The recast Energy Performance of Buildings Directive, (EU) 2024/1275, layers a second, dated obligation on top: solar installations become mandatory on new public and non-residential buildings above 250 square metres from 31 December 2026, then extend to existing public buildings and new residential stock through 2029. Both sit inside the European Commission’s Green Deal and REPowerEU programme, which links accelerated permitting to the bloc’s Paris Agreement NDC commitments and gives EPC contractors serving the rooftop segment a build schedule that runs independent of wholesale power prices.

Grid Equipment Reshoring and EU Carbon Policy Are Adding EPC-Adjacent Scope

Siemens Energy’s February 2026 commitment of USD 421 million to expand transformer manufacturing in Charlotte, grid-technology engineering in Raleigh, and a parts and service centre near Winston-Salem, on top of a USD 150 million investment announced in 2024, is adding domestic grid-equipment capacity that shortens lead times for US substation EPC packages; the expansion qualifies for US Inflation Reduction Act tax credits under Section 45X. In Europe, the Net-Zero Industry Act’s Article 23 obligation requires oil and gas producers to develop 50 million tonnes per year of CO2 injection capacity by 2030, with the European Commission naming obligated producers in May 2025; the three permitted and seven permitting storage sites each carry construction and pipeline EPC scope adjacent to conventional power project delivery. Rising EU Emissions Trading System carbon prices, and the phase-in of the Carbon Border Adjustment Mechanism on imported steel and aluminium, are the pressure the obligation formalises: CBAM raises the landed cost of carbon-intensive grid-equipment inputs even as the same policy funds the capture infrastructure.

Interconnection Queue Congestion Is Deferring US Greenfield EPC Award Timing

US interconnection queues have pushed roughly 60 GW of proposed capacity into 2027-2028, delaying the point at which developers can award full-scope EPC contracts; IEA data on grid bottlenecks places the US backlog among the most severe of any OECD market. FERC Order No. 2023 is intended to compress that backlog, but it has yet to clear the pre-reform queue in the largest regions. IRA domestic-content qualification requirements add a further 8 to 12 months to equipment procurement, and BNEF’s LCOE tracking shows the compliance premium narrowing only slowly as US module and inverter capacity ramps.

Floating Offshore Wind’s Cost Premium Is Slowing FID Conversion in Europe

Floating offshore wind EPC packages in Europe run approximately 40% above fixed-bottom equivalents on an LCOE basis, a gap driven by mooring, dynamic cabling and port-side assembly requirements still short of serial-production scale; the technology’s higher capacity factor in deep-water Atlantic sites narrows the gap but does not close it. Developers are deferring final investment decisions in early-stage Atlantic and Mediterranean lease areas until EPC costs fall enough to clear at prevailing Contracts for Difference strike prices or corporate PPA rates, a threshold the UK’s AR6 CfD round did not reach for floating bids. Grid-connection data published by ENTSO-E shows floating projects further back in national interconnection queues than fixed-bottom equivalents, adding a second layer of timing risk on top of the cost gap.

Regional Analysis

Siemens Energy committed USD 421 million in February 2026 to expand power transformer manufacturing in Charlotte, grid-technology engineering in Raleigh, and a parts and service centre near Winston-Salem, building on a 2024 investment and adding roughly 500 jobs. Interconnection queues have deferred an estimated 60 GW of capacity into 2027-2028, while IRA domestic-content rules add 8-12 months to equipment procurement.

Floating offshore wind EPC costs run roughly 40% above fixed-bottom installations, weighing on North Sea and Atlantic project economics. The European Grids Package, which reached Council general approach on 26 June 2026, sets binding EU-level permitting deadlines and targets more than 100,000 km of new transmission lines, with over half of needed projects still awaiting permits.

Asia-Pacific led power generation EPC with a 59.4% share in 2025 and held the largest transmission and distribution EPC share, at 48.1%, the same year. T&D EPC in the region is also projected to grow fastest of any segment, at an 8.60% CAGR through 2031, driven by grid build-out in China and India.

Middle East and Africa EPC demand centres on Gulf giga-projects, where sovereign-backed tenders finance gigawatt-scale green-hydrogen developments tied to national diversification programmes. Utility-scale generation and associated export infrastructure are procured through state-backed EPC packages rather than merchant tenders, concentrating contract award among a small pool of sovereign offtakers.

South America is projected to grow fastest among regions for power generation EPC, at a 7.50% CAGR through 2031. Brazil’s competitive auction wins and Chile’s hydrogen-linked project pipeline anchor the pace, alongside an expanding biomethane sector: 16 producers held ANP authorisation as of October 2025, with roughly 989,321 cubic metres per day of installed capacity.

Segment Analysis

Project Type

• Greenfield (largest, 58.22% share) – An EPC project that builds a new power generation or transmission facility on a previously undeveloped site with no existing infrastructure to integrate
• Brownfield – An EPC project that expands, retrofits, or modernizes an existing power plant or grid asset, requiring integration with legacy equipment and operations
• Turnkey – A contracting model in which a single EPC firm handles engineering, procurement, and construction and delivers a fully operational facility ready for immediate handover to the owner

Greenfield project delivery led the segment with a 58.22% share in 2025. Most new capacity additions, particularly utility-scale renewables and new generation and transmission builds required to serve electricity load growth, are contracted as full-scope EPC greenfield packages rather than piecemeal awards. A single greenfield contract lets a developer transfer schedule and interface risk to one EPC firm rather than coordinating separate vendors across a live site. Developers typically award that contract only after the project reaches final investment decision, by which point a signed power purchase agreement with a named offtaker is already underwriting the construction debt; IEA capacity-addition data point to solar PV and onshore wind as the technologies carrying the bulk of new-build FIDs. Brownfield scope in Europe is increasingly tied to compliance work: retrofits that cut emissions intensity under the EU Emissions Trading System, sharpened by the incoming Carbon Border Adjustment Mechanism, require EPC firms to integrate new abatement equipment with grid data reported through ENTSO-E. Turnkey delivery is growing the fastest of the three project types. Developers and financiers increasingly prefer a single point of contractual accountability, particularly where financing conditions and content-compliance rules complicate multi-vendor coordination. FERC Order 2023 interconnection reform in the US and competitive CfD auction rounds in Europe are compressing the window between FID and commercial operation, and a bundled turnkey mandate is the more reliable way to hold one EPC firm to that shortened timeline.

Service Type

• Engineering – Design and technical planning services covering feasibility studies, front-end engineering, and detailed design of power generation, transmission, or distribution assets
• Procurement – Sourcing, purchasing, and logistics management of equipment, materials, and components required to build a power project, including vendor selection and supply contracts
• Construction (largest, 39.2% share) – On-site civil, mechanical, and electrical works including installation, erection, and commissioning of power plant or grid infrastructure built per the engineering design
• Project management – Coordination of schedule, budget, quality, and risk across the engineering, procurement, and construction phases to deliver a power project as a single integrated contract

Construction held the largest share of service-type revenue at 39.2% in 2025. Civil works, equipment installation, electrical integration and commissioning are the most labour- and cost-intensive phase of an EPC contract, and that cost weight carries directly into revenue share regardless of project type. Commissioning tests also fix the capacity factor a plant is contracted to deliver under its PPA, so construction quality carries into long-term generation revenue, not just build cost, and it feeds directly back into the LCOE the developer quoted at bid stage. Interconnection queue congestion under FERC Order 2023 reform is lengthening the construction-to-energisation window in the US, pushing more schedule risk onto the EPC contractor’s balance sheet. Procurement is expanding fastest among the four service categories. Domestic-content rules attached to incentive regimes such as the US Inflation Reduction Act tax credits are lengthening vendor qualification and sourcing cycles, while BNEF cost-curve data show module and turbine pricing as the largest swing factor in EPC bid competitiveness. Together these are pulling procurement scope, and the fees attached to it, away from simple purchase-order execution and toward managed, compliance-driven supply-chain services that EPC firms increasingly retain in-house rather than delegate to subcontractors.

Country Growth Comparison

Country-level momentum in the Power EPC Market traces to named projects and policy rather than a single blended rate. China and India anchor Asia-Pacific’s 59.4% share of power generation EPC and its 8.60% CAGR in transmission and distribution EPC. Brazil’s auction wins and Chile’s hydrogen-linked pipeline drive South America’s 7.50% CAGR, the fastest of any region. The United States is absorbing a 60 GW interconnection backlog alongside IRA-linked reconductoring funding, while Germany’s 1.6 GWh battery storage EPC award points to accelerated storage contracting across Europe.

Competitive Landscape

The Power EPC Market is fragmented, with contract awards split across large multinational contractors and strong regional players rather than concentrated among a handful of firms. Competition turns on delivered project cost, execution record on prior EPC contracts, balance-sheet strength to carry construction-phase working capital, and increasingly on local-content compliance under regimes such as the IRA. Established contractors leading the field include Bechtel Corporation, Fluor Corporation, Worley Limited, Larsen & Toubro Limited, KBR, Inc., Jacobs Solutions Inc., McDermott International, Technip Energies N.V., Wood Plc and Saipem S.p.A.

In February 2026, Adani Energy Solutions Ltd. secured long-term financing from a group of Japanese banks for an HVDC transmission line carrying solar power from Rajasthan into India’s national grid, extending its transmission EPC pipeline. In November 2025, HyperStrong International GmbH signed an EPC agreement with LEAG Clean Power GmbH to deliver a 1.6 GWh battery storage project in Germany, among Europe’s largest on completion, marking EPC firms’ expansion into storage-specific contracting.

Strategic Outlook

The clearest whitespace lies in interconnection and grid-reinforcement EPC tied to reconductoring programmes and permitting reform, benefiting contractors with transmission execution records in the United States and the European Union. Realising it depends on funding awards and permitting timelines converting into signed contracts rather than deferred queues.

By 2035, delivery is expected to shift toward turnkey and storage-integrated contracts as developers consolidate accountability with fewer counterparties. Local-content compliance and balance-sheet strength are expected to weigh as heavily as unit cost in contractor selection, favouring larger, vertically capable EPC firms.
