ATA Renewables brings more than 20 years of international experience and participation in projects exceeding 300 GW to design robust, optimized renewable solutions ready to be executed, financed, and successfully operated.
We support developers, IPPs, EPC contractors, investors, and public entities across all phases of the project lifecycle, from early-stage development through commercial operation. Our multidisciplinary team provides technical independence, risk control, and financial insight to maximize the value of every asset.
More than 500 clients in over 50 countries endorse our experience and ability to deliver technical solutions tailored to each market and technology.
We understand engineering as a critical component in ensuring the technical and financial viability of every renewable energy project.
Our international experience and involvement throughout the entire lifecycle enable us to deliver optimized, executable solutions aligned with our clients’ strategic objectives.
We act as an independent technical partner, ensuring quality, control, and long-term performance.
Permitting engineering establishes the technical foundation that enables a project to advance through administrative and regulatory milestones. At this stage, we define the initial technical configuration, ensuring consistency, feasibility, and alignment with grid access and interconnection requirements.
We develop engineering solutions for solar, wind, storage, pumped-storage hydro, hybrid projects ranging from 5 to 500 MW, and transmission infrastructure up to 400 kV, ensuring technical robustness from the earliest stages.
Scope of Services:
⦿ Grid access and interconnection studies
⦿ Technical studies, including topography, hydrology, geotechnics, ground-penetrating radar, and bathymetry, among others
⦿ Plant and evacuation infrastructure design
⦿ Basic and detailed permitting documentation
⦿ Engineering support for administrative approvals
⦿ Professional certifications and declarations
⦿ Ongoing support throughout the permitting process
A technically well-structured permitting phase reduces delays, avoids rework, and anticipates critical design constraints.
Our approach enables regulatory and technical certainty, laying the groundwork for a solid and bankable Ready-to-Build phase.
The basic engineering phase defines the project’s technical architecture and directly influences its long-term profitability. At ATA Renewables, we optimize design from both a technical and financial perspective, identifying the optimal balance between energy yield, CAPEX, and operational efficiency.
We work on solar, wind, storage, and hybrid projects, preparing the technical foundation required for IPP or EPC tender processes and financial close.
Scope of Services:
⦿ Comparative analysis of technological alternatives
⦿ Integration of hybrid solutions (solar, wind, BESS)
⦿ Preliminary BOQ definition and optimization
⦿ Layout and electrical configuration optimization
⦿ Development of plant and transmission basic engineering
⦿ Pre-construction engineering for EPC processes
An optimized basic engineering phase improves LCOE, reduces risks when permitting, and prevents cost overruns in later stages.
Our approach combines energy modeling, technical criteria, and economic vision to maximize asset value prior to execution.
Detailed engineering is the phase in which the project becomes fully defined for construction. We translate basic engineering into precise construction documentation, minimizing on-site risks and avoiding cost overruns resulting from undefined items.
At ATA Renewables, we deliver detailed engineering for solar, wind, storage (BESS), and transmission infrastructure projects, ensuring technical consistency, economic optimization, and alignment with contractual requirements.
Scope of Services:
⦿ Civil, mechanical, and electrical construction drawings
⦿ Detailed layout and MV/HV network design
⦿ Civil, mechanical, and electrical calculations
⦿ Single-line diagrams and protection systems
⦿ Final BOQ optimization and closure
⦿ Technical documentation for construction and procurement
Robust detailed engineering reduces construction deviations, improves interdisciplinary coordination, and ensures the project is ready for efficient execution and cost control.
Our experience in Owner’s Engineering and construction supervision enables us to develop engineering solutions grounded in real-world buildability—not just theoretical design.
Tendering and award processes are critical milestones that define the project’s technical, contractual, and financial balance. ATA Renewables acts as an independent technical advisor, providing rigor in the evaluation and negotiation of EPC proposals.
We support developers, IPPs, and public entities in competitive processes, strengthening their technical position and reducing contractual risk.
Scope of Services:
⦿ Design and structuring of EPC tender processes
⦿ Preparation of technical tender documentation
⦿ Technical evaluation and comparative analysis of bids
⦿ Identification of risks and technical deviations
⦿ Technical support in contract negotiations
⦿ Advisory support in IPP and financing processes
A well-structured tender process ensures selection of the most technically robust and economically competitive solution.
Our international experience and market knowledge help minimize technical and contractual risks before EPC contract signature.
As the Owner’s Technical Representative, we oversee project engineering to ensure it is carried out in accordance with the established technical and contractual standards.
We act as an extension of the developer's or Independent Power Producer’s (IPP) technical team, safeguarding their interests from the pre-financial close stages through commercial operation and subsequent follow-up.
Scope of Services:
⦿ EPC technical design review
⦿ Technical and document management of the project
⦿ Review of quality procedures and FAT reports
⦿ FAT and SAT supervision, as well as factory quality control
⦿ Construction supervision and on-site quality control
⦿ Site inspections
The presence of an independent Owner’s Engineer reduces execution risks, improves contractual oversight, and ensures that the asset meets the defined technical and financial expectations.
Our experience across international projects of varying scales enables us to anticipate deviations and act proactively rather than reactively.
During the execution phase, technical coordination and quality control are critical to meeting schedule, budget, and technical requirements. At ATA Renewables, we provide comprehensive site management services, ensuring efficient execution aligned with contractual obligations.
We act as the coordination point between the developer, EPC contractor, and subcontractors, providing independent technical oversight and a holistic view of the project.
Scope of Services:
⦿ Owner’s Site Supervision and Site Management
⦿ Civil, mechanical, electrical, and high-voltage coordination
⦿ Quality control and quality management
⦿ Document management and change control
⦿ Commissioning coordination
⦿ Health and safety supervision
⦿ Environmental management and permitting support
A structured technical management approach during construction reduces deviations, improves traceability, and prevents contractual disputes.
Our approach ensures continuous technical oversight, regulatory compliance, and a smooth transition into commissioning and commercial operation.
