Operation & Maintenance
We supervise plant operations, maintenance activities, and performance, ensuring optimal plant status and efficiency.
Asset Advisory
Our asset management expertise focuses on optimizing costs and maximizing benefits, helping clients achieve sustainable and profitable operations.
End-to-End Engineering Solutionsfor Renewable Energy Projects
Basic design for feasibility studies, tenders, and permits during the development phase.
Detailed design for construction.
Basic and detailed engineering scopes can be extended to engineering for construction when you move forward with your project. We would help you with the engineering of the generation facility as well as evacuation lines and interconnection infrastructure. We have experience in Wind, Solar, Transmission Line and High Voltage Substations. Not only the design is our scope, we´ll prepare full project, measurements, calculations to execute a good project according to the Good Practices of Engineering Book. If you are an EPC seeking to externalize engineering services, ACS engineering can be your engineering firm. We can act as an extension of your team.
Revision Owner´s engineering.
Owner’s Engineering (OE) is a figure typically engaged by Client that wants to rely on a top experienced engineering firm to take lead on a project execution. OE shall assure,-that the project is properly designed. The scope usually includes a detailed engineering review, construction and commissioning protocols. Additional to engineering, this activity is linked with supervision on site, during construction works, to when ACS engineering propose to supervise construction, planning, quality. As well as FAT supervision. These tasks can be complemented with project management activities. Sometimes the OE can join a project in a precedent phase, prior to EPC selection, providing consultancy services for the EPC tender and contract negotiation. At ACS engineering has experience in all these services. We have participated on some projects worldwide.
Comprehensive Advisory Services for
Renewable Energy Projects
Technical Due Diligence
A Technical Due Diligence (TDD) is designed to conduct a comprehensive project risk assessment for acquisitions, financing, or refinancing—whether for debt or equity. It identifies potential risks and provides recommendations for mitigation measures. Our Advisory Department has carried out numerous TDDs on renewable energy projects, giving us a deep understanding of key risks and how to address them.
The scope of a TDD typically includes evaluations of natural resources (such as solar and wind), energy production estimates, environmental impact assessments, permit evaluations, technical reviews of licenses and authorizations, asset lifespan analysis, and contract reviews (EPC, O&M, and PPA contracts). Each TDD can be tailored to the specific needs of a project.
For M&A transactions, the TDD process is similar but adapted to the project’s current status. For example, a TDD for a greenfield project will focus on different areas than one for an operational project. In some cases, the TDD can be supplemented with product due diligence (PDD) to provide a more comprehensive evaluation.
Feasibility Studie
A feasibility study, similar to a Technical Due Diligence (TDD), is typically requested at an earlier stage of project development to assess its technical and economic viability. The scope of a feasibility study is fully customized to meet the specific needs of the project and client. While it may share some content and scope with a TDD, the key difference is that a feasibility study focuses on optimizing and defining a project, whereas a TDD evaluates an already defined project.
At ACS Engineering, our feasibility studies often go beyond the basics, including irradiance studies, assessments of environmental requirements, infrastructure considerations such as roads, railways, rivers, or canals, water level changes, drainage needs, and geotechnical analysis — all aimed at minimizing risks and ensuring the project’s future success.
Tenders, Purchasing and Inspection in supplier´s factories.
Our advisory team can support you whether you are planning to participate in a tender or are responsible for organizing one. At ACS Engineering, we tailor our services to your specific role and needs:
- Assisting tender participants or bidders.
- Supporting IPP companies participating in IPP tenders or auctions.
- Assisting EPC companies involved in EPC tenders.
- Helping clients organize and manage tenders or bids.
- Running EPC tenders to select an EPC Contractor.
- Running IPP tenders to select an IPP.
The scope for each scenario is fully customizable to meet the specific needs and context of each client, whether you are a government institution, multilateral organization, utility, or a private EPC or IPP.
Contract Negotiations
Our team can assist with EPC Contracts, O&M Contracts, PPA, Transmission Agreements, and main equipment supply agreements. We can help by reviewing contracts, providing recommendations, and participating in meetings with you, your suppliers, or subcontractors.
The ACS Engineering team specializes in contract drafting and negotiations, particularly on technical issues. With our expertise in market standards and deep technical knowledge, we help you minimize technical risks and ensure smooth contract execution.
Construction Supervision
As projects grow larger and more complex, and margins become tighter, having the right guidance is essential to ensure they are completed on time, within budget, and to the required specifications. Specialist project management and hands-on experience are key to achieving the best possible results.
At ACS Engineering, with our extensive experience in successful construction, we can guide you through the most critical aspects of your project. Whether you need end-to-end project management, specialist implementation teams, or HSE and Quality Assurance support, our experts are dedicated to delivering the best possible outcomes tailored to your specific needs.
Operation & Maintenance Supervision
After project completion, the Operation and Maintenance (O&M) phase begins. ACS Engineering can provide supervision of all activities for subcontractors or third parties involved in the project. As specialists in this field, we will oversee periodic and preventive maintenance, as well as repair operations.
With our extensive experience in successful O&M activities, ACS Engineering will guide you through the most critical aspects of project execution. Our role includes continuous oversight, inspection, and coordination of work to optimize production and prevent equipment malfunctions that could lead to deterioration or loss of production.
Management of the Technical and
Financial Aspects of Assets
Comprehensive Asset Management for Optimal Performance
Engineering for renewable energy projects is not standard and require specific tailoring for an optimized result. An optimized project engineering is essential to maximize your returns but also to minimize risks. If you are developing a project and you are seeking a specialized team to optimize the engineering for maximum project returns, ACS engineering Department will help you achieve your goal. The level of detail and optimization can be adapted to your need and your project status of development. We can just carry out a technology comparison or we can provide a detailed optimized project design including BoQ, Yield Assessment and project economic´s estimations. Out team have performed the design optimization for multiple projects worldwide.
