Grid connection design for pv power plants

greentech is your partner for grid connection design of your photovoltaic project! Our experienced experts support you with the route design, the correct dimensioning of transformer and substation as well as with the grid connection application and the communication with the grid operator.

Reliable grid connection design with specific know-how and many years of experience

Grid connection design is an elementary component of system engineering. With many years of experience and technical expertise, we determine the correct dimensioning of grid connection components, such as the route, high-voltage transformers or compensation systems, on the basis of your planned photovoltaic system and the specifications of the grid operator. For this purpose, we model the entire system including the route and high-voltage transformers using current software solutions. We perform load flow and short-circuit current calculations and determine the current carrying capacity of the line and transformers, also considering normative requirements for reactive power. Based on the results, we recommend a technically required or commercially optimized cable dimensioning for your route and the power range of the required high-voltage transformers. The information can be used directly when procuring materials. Within the scope of our grid connection services, we also take over the submission of the grid connection application as well as the complete communication with the grid operator.

greentech is the right partner for your
grid connection design when…

Electrical design is not your specialty? But it is ours! Our experienced grid connection engineers and electrical engineering specialists also have extensive knowledge of photovoltaic project development, engineering, and O&M. This gives us a holistic view of the PV system and allows us to develop the optimal grid connection solution for your system individually and reliably – including submitting the corresponding grid connection application to the grid operator and further processing and communication. In addition to the preparation of our own route design and dimensioning recommendations, we analyse in our activity as an independent assessor already prepared designs and evaluate their result.

We keep an eye on all technical regulations and the conditions of the grid operator. When designing the grid connection, we ensure that the route and transformer design are carried out in accordance with the applicable Technical Connection Rules (TCR Medium Voltage / TCR High Voltage) and can be connected to the grid in accordance with the specified connection conditions of the respective grid operator.

We determine suitable grid connection options with the grid operator, the corresponding connection conditions and prepare the required grid connection application for your plant. To ensure that the contract can be concluded as quickly as possible, we coordinate closely with the grid operator and take care of all activities and requirements that are relevant for obtaining the grid connection permit.

At greentech, experienced grid connection specialists and electrical engineers deal with all technical, normative, and economic issues related to grid connection. As an integrated PV company, we also incorporate practical findings and interdisciplinary knowledge from the areas of project development & financing, plant construction and O&M into our grid connection services.

At greentech, you receive all services of grid connection design reliably from a single source. You have a fixed contact person who coordinates all activities related to your grid connection design. We keep you transparently informed about all activities and results and advise you on necessary technical decisions.

The technical minimum design of the route not only provides clarity about the required cable cross-section, but also about the minimum investment costs to be incurred. If you would like to reduce cable losses in a given plant design by using a larger cable cross-section and realize a correspondingly yield-optimized route design, we will determine for you the cable cross-section that enables the best possible economic profit for your plant on the basis of plant-specific economic efficiency calculations.

What makes our grid connection design services special

Substantial grid connection know-how and many years of photovoltaic experience

Black box grid connection design? Not with greentech! Our experienced grid specialists and electrical engineers will fill the gap between plant design and grid connection for you with our knowledge of electrical engineering and photovoltaics. We ensure that the grid connection design of your plant is carried out in accordance with the applicable legal and normative framework conditions, that the cables are protected against overload and premature aging, and that the plant can thus later feed the intended electricity yield into the grid.

Full-service grid connection design from
a single source

We take care of all details of grid connection design, determine the route layout and the dimensioning of the transformers, identify possible grid connection points, submit the grid connection application, and take over further coordination with the grid operator. You have a fixed contact person at greentech who coordinates all activities within the framework of project management and reports to you. Think of us as your outsourced grid connection department that also looks after your commercial interests – we are there to support you with advice, action, and experience!
