General Designer
of energy investments, HV substations, industrial systems, and BESS

Home page / Offer / General Designer

Comprehensive design – HV substations, Main Power Supply Points, energy storage systems, and complete power systems ready for implementation.

We oversee the entire design process – from concept development and grid connection analysis to detailed design documentation, 3D and BIM modeling, and as-built documentation. We deliver complete HV substation projects – including the integration of BESS energy storage systems, HV switchgear, and MV power systems.

Who is the General Designer service for?

Our General Designer service is dedicated to investors, EPC contractors, and companies involved in energy and industrial projects, including:

Power plants and
CHP plants

Thermal waste
treatment plants

Battery Energy Storage Systems (BESS)

Wind and PV farms

HV substations

Why Enetecs?
We manage the design process from analysis to implementation.

Comprehensive design approach – from HV substations and switchgear systems to cable routes, BESS, I&C systems, and building and lighting installations.
Experience with BESS-integrated projects – we integrate energy storage systems with HV/MV infrastructure, PV installations, and wind farms. We develop concepts, prepare grid impact analyses, design and coordinate connections with Distribution/Transmission System Operator.
Systematic and interdisciplinary thinking – we cover the entire power system layout as well as supporting disciplines (architecture, structural engineering, I&C, process piping, sanitary systems).
Regulatory support – we assist in communication with Distribution/Transmission System Operator. and public institutions or independently conduct coordination, prepare expert opinions, and obtain necessary permits.
Understanding EPC investments and procurement processes – we support clients not only with design, but also during prefabrication, equipment selection, author supervision, and on-site implementation.
Precision and speed of delivery – we operate with an in-house design team, licensed design tools, an efficient project management system, and experience in international projects (e.g., UK, France, UAE, Serbia, Sweden).
3D modeling and BIM technology – we design using BRCM, AVEVA E3D, Revit, SmartPlant 3D, and Navisworks to ensure precise interdisciplinary coordination.

the role of the General Designer

General Designer for Power Investments – Full Responsibility for the Design Process

In large-scale energy and industrial investments, the key factors are the consistency of the concept, precision of solutions, and coordination of all disciplines. The role of the General Designer is to ensure that from the first sketches to the as-built documentation, every decision is deliberate and compliant with technical, regulatory, and investor requirements. At Enetecs, we take full responsibility for the entire process – from feasibility studies and grid connection analyses, through 3D design and BIM, to the preparation of construction-ready documentation.

Comprehensive Design of HV Substations, GPO, GPZ and BESS

Our expertise covers the full design of high-voltage substations, main supply points, medium- and low-voltage switchgear, as well as Battery Energy Storage Systems (BESS). We deliver integrated solutions – where HV/MV systems, generation sources, building installations, and I&C automation operate in a safe, efficient, and grid-compliant manner. Our projects also include cable management, lighting, HVAC, and structural works, ensuring that investors receive complete, ready-to-build documentation.

Projects for Power, Industry, and Renewables

The General Designer service is dedicated to investors, EPC contractors, and companies implementing projects in the energy and industrial sectors. We work for power plants and CHP plants, waste-to-energy facilities, wind and solar farms, energy storage systems, and industrial facilities. Each project is approached individually – considering not only technical requirements but also industry specifics and the client’s business context.

Integration of Energy Storage with HV and MV Infrastructure

One of our strengths is experience in projects where BESS systems are integrated with the power grid infrastructure. We prepare concepts and grid impact analyses, design connections and switchgear layouts, and coordinate them with DSOs or TSO (PSE). This ensures that investors receive fully implementable solutions that meet formal and technical requirements from the outset.

Design Process Management in EPC Formula

We understand how EPC projects are executed – and that success depends on seamless cooperation between designers, contractors, and technology suppliers. That is why we support our clients not only during the design stage but also in procurement, prefabrication, author supervision, and construction phases. We work with reputable equipment manufacturers and prefabrication companies, enabling us to guarantee the highest quality of delivered solutions.

Precision, Speed, and Advanced Design Tools

At Enetecs, we combine engineering precision with operational efficiency. We rely on our in-house design team, licensed design environments, and proven project management processes. 3D modeling and BIM technology in BRCM, AVEVA E3D, Revit, SmartPlant 3D, and Navisworks enable accurate interdisciplinary coordination and minimize collision risks during construction.

Collaboration Process – from Analysis to As-Built Documentation

Every project begins with an analysis of the client’s inquiry and input data. Based on this, we prepare a tailored offer and a detailed work schedule. After the scope and input documents are approved, we proceed with the project execution, which concludes with the delivery of comprehensive documentation. If new data or changes arise during the process, we flexibly adapt the design to meet all requirements and ensure readiness for implementation.At Enetecs, the role of the General Designer goes far beyond coordinating drawings and reports. It is the responsibility for the coherence and quality of the entire investment – from the first sketch to commissioning. Our goal is to deliver solutions that ensure safety, efficiency, and readiness for the future challenges of the energy and industrial sectors.
