Additional Technical Services
Complementary services that typically connect to the core areas of photovoltaics, battery storage, substations and grid studies.
Engineering, interfaces and documentation as one system
These complementary services close technical gaps between design, procurement, evidence and project decisions. Varian Energy structures requirements, reviews documentation and keeps interfaces between the client, suppliers, network operator and certification body consistent.
- Engineering driven by expertise and experience
- Interfaces clearly defined
- Documented for review
Technical scope in detail
The service modules are clearly structured and can be combined to match the project phase, plant configuration and technical requirements.
Technical Procurement & Supplier Interface
Technical support with specification, quotation review, supplier selection and interface clarification for key electrical components.
- Transformer and substation (HV/MV)
- PV distribution cabinets
- BESS distribution cabinets
- SCADA
- Power Plant Controller (PPC)
- Energy Management System (EMS)
Support for Plant Certification
Varian Energy supports the technical preparation and coordination of plant certification processes and consolidates the required technical information together with the network operator, project stakeholders and the certification body.
- Plant certificate type A and B
- Coordination with the certification body
- Technical preparation of evidence documents
- Clarification of open technical points with the network operator
Which certification route applies depends on the specific plant and connection configuration and on the applicable regulations. The certificate itself is issued exclusively by the accredited certification body.
Feasibility Studies
Technical assessment of site, plant concept, grid connection and variants as a reliable basis for the next project decisions.
- Site conditions
- Preliminary layout
- Connection conditions
- Preliminary electrical concept
- Technology variants
- Yield simulation
- PV and BESS integration
- Technical project risks
- Investment and revenue estimation
- Grid connection inquiry with the responsible grid operator
The scope is technical and does not include financing or legal advisory services.
Technical Advisor
