Wind OEMs & Tower Manufacturers
Our Story
Sphere Renewables is a manufacturing and supply chain partner to tier‑1 wind OEMs and tower manufacturers, including the largest tower producer globally and some of the world’s leading wind turbine companies. Our role is to take critical components, assemblies, and kitting off your plate so you can focus on turbine design, core production, and fleet performance.
How We Help OEMs & Tower Manufacturers
01
Strengthening and Localizing Your Supply Chain
We design programs that combine U.S. manufacturing with our global network in Europe, China, and Mexico to create resilient, flexible supply chains. This allows you to support localization and domestic‑content goals while still benefiting from competitive global sourcing, smart routing, and regional finishing/assembly.
02
Reducing Cost and Tariff Exposure
By shifting more value-added work into North America and optimizing where each component is produced, we help you lower total landed cost, not just piece price. Our approach supports tariff mitigation, reduces long‑haul freight and handling, and cuts rework and delays at plants and sites.
03
De‑Risking Projects and Operations
We supply pre‑assembled nacelle and tower components, tower internals kits, and transport/site equipment that arrive ready for production or installation. This reduces site labor, crane time, and schedule risk, and creates smoother hand‑offs to EPC and BOP partners during new build, repower, and O&M campaigns.
What We Do for OEMs & Tower Clients
Nacelle & Large Mechanical Assemblies
Build‑to‑print nacelle cover assemblies, hub frames, and large mechanical subassemblies.
Mixed‑model production and JIT deliveries to plants and laydown yards.
OEM‑grade quality systems, welding, and inspection to support current and next‑gen platforms.
Tower Internals, Hardware & Components
Fabricated and machined parts in steel, stainless, and aluminum.
Tower internals kits: platforms, ladders, brackets, fasteners, railings, and accessories.
Tower feet storage and refurbishment, supporting new build and repower.
Kitting, Transport Equipment & Site Readiness
Site and installation kits for towers and nacelles (mechanical, electrical, and tooling content).
Transport frame and equipment refurbishment programs to extend asset life and reduce capex.
Optimized packing and loading through our Colorado facilities and our own trucking fleet.
Parts, Spares & SKU Management
5,000+ parts under management
We manage and supply more than 5,000 individual part numbers across turbines, towers, and balance‑of‑plant components, covering both serial production and spare parts.
Localization & tariff‑smart sourcing
Dual‑sourcing strategies that combine U.S. manufacturing with our global network in Europe, China, and Mexico.
Structured transitions from imported to localized content to support domestic content targets and IRA‑driven strategies.
Tariff and duty mitigation through smart sourcing, routing, and local finishing/assembly.
Direct‑ship spare parts programs
Centralized spares, with direct shipment from Sphere to OEM warehouses, service hubs, or sites.
Kitted spares (e.g., tower internals repair kits, nacelle hardware packs) that reduce pick/pack and site errors.
Options for OEM‑branded packaging and documentation to keep your customer experience consistent.
How We Strengthen Your Strategy
More resilient supply chains
We design part and assembly programs that absorb disruption—multiple manufacturing regions, buffer stock where it matters, and domestic final assembly close to your plants and projects.
Lower LCOE, not just lower part price
Reduced freight, tariffs, and handling via regional manufacturing and fiberglass in North America.
Fewer vendors and POs through assemblies and kitting.
Less site rework, crane time, and downtime through better‑prepared components and spares.
Smoother hand‑offs to EPCs and service
Pre‑assembled, pre‑kitted components and spares mean EPC/BOP and O&M partners see fewer gaps and delays, which, in turn, strengthen your platform performance and reputation.
Let’s Talk
If you’re looking to localize content, reduce cost and tariff risk, and make your supply chain more resilient, Sphere can act as an extension of your operations and sourcing teams for wind turbines and towers.
