Grid connection for PV, BESS, and wind<\/h1>

We support you with the grid connection of PV, BESS, and wind projects \u2013 from the initial application to the grid operator, through grid connection planning, to quality assurance for the construction of substations and transfer stations.
This ensures that grid operator requirements are understood early, decisions are transparent, and interfaces are properly prepared.<\/p>\n<\/div>

Grid connection & integration<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

We ensure that your PV system, battery storage (BESS), or wind power\u00a0 plant (WPP) is optimally integrated into the power grid \u2013 from the initial non-binding grid connection application, grid connection design, support with the procurement of transformers, substations, and calbles to quality assurance during the construction of the grid connection.<\/p>\n

We identify potential grid connection points, submit non-binding grid connection applications, and undertake \u2013 in accordance with all grid operator specifications \u2013 the appropriate grid connection design with a comprehensible design for connection to medium or high voltage. We review existing grid connections for optimisation potential, evaluate flexible grid connection agreements (FCA) for your project if necessary, and support you in negotiations with the grid operator.<\/p>\n

Our work helps you avoid surprises when connecting to the power grid, allows for realistic project cost calculation, and lays the foundation for stable and reliable operation of your system.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

When grid connection services<\/span> from greentech are the right solution for your project<\/h2>\n<\/div><\/div>\n<\/div>\n\n
\n

If you need early guidance on connection options.<\/h3>

Location and capacity are roughly determined, but you need to quickly know which grid connection points are realistic and what the next step looks like.<\/p>\n<\/div><\/div>\n\n

If you want to structure communication with the grid operator.<\/h3>

Inquiries, documents, and technical requirements should be clearly bundled to enable faster and more consistent decision-making.<\/p>\n<\/div><\/div>\n\n

If you require reliable preliminary design for the grid connection.<\/h3>

From \"connection generally possible\" a technical concept should emerge \u2013 e.g., as a basis for project calculation and subsequent planning decisions. The preliminary design clarifies key aspects (connection variant\/voltage level, central components, interfaces) and aligns them with grid operator specifications before you proceed to detailed planning.<\/p>\n<\/div><\/div>\n\n

If there are restrictions at the grid connection point (power, reactive power, feed-in requirements).<\/h3>

Grid operator requirements influence design or economic viability \u2013 an early technical assessment and variant evaluation provides clarity.<\/p>\n<\/div><\/div>\n\n

If you want to specifically examine grid connection optimisation before planning \"too far ahead.\"<\/h3>

You want to compare options (e.g., connection variant, dimensioning, metering\/concept approaches) to reduce costs, risks, and re-planning, or you want to cooperate with other developers or operators.<\/p>\n<\/div><\/div>\n\n

If you need a professional sparring partner for grid topics and communication with the grid operator.<\/h3>

Technical topics (requirements, design, metering\/protection\/control concept) should be professionally classified, inquiries structured, and your interests effectively represented in discussions.<\/p>\n<\/div><\/div>\n\n

If your project changes \u2013 and grid integration needs to be properly adjusted.<\/h3>

For adjustments to capacity, technology (PV\/BESS\/Co-location), or schedule, we help identify impacts early and clearly define the next steps.<\/p>\n<\/div><\/div>\n\n

If you want to reduce planning risks before proceeding to detailed design.<\/h3>

You want to prevent later planning stages from having to be re-initiated due to grid restrictions or unclear specifications.<\/p>\n<\/div><\/div>\n\n

If you want to evaluate flexibility as an option (e.g., FCA) and realistically assess opportunities.<\/h3>

You want to understand if a flexible grid connection approach is generally suitable and what prerequisites typically need to be met.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Substation engineering \u2013 if grid connection is only possible via a dedicated substation<\/h2>\n<\/div><\/div>\n\n

If grid connection can only be realized through the construction of a dedicated substation, the substation becomes the central point of technical design and implementation.<\/p>\n

With our implementation package for substations, we bundle the relevant engineering services into a continuous service chain \u2013 from preliminary design, through permitting design & documentation, to the detaild electrical design of the connected system(s) (PV, wind, and\/or BESS) as a technical basis for substation design and interfaces. We consider SCADA and control requirements from the outset \u2013 including implementation via the \"greenCORE\" power plant controller. Building on this, we prepare the tender documents for the substation and transformer, support contract negotiations, and accompany the implementation on site until acceptance.<\/p>\n

This provides you with a consistent technical basis, clear interfaces, and documents that can be directly used for project implementation \u2013 without discontinuities between grid requirements, design, procurement, and commissioning.<\/p>\n

Our services bundle the central steps necessary to technically connect a PV, wind, or storage system<\/strong> to the power grid \u2013 from initial orientation in the early project phase to a reliable basis for further planning. We handle structured communication with the grid operator and prepare the necessary documents so that you can make informed decisions. Our services can be commissioned individually \u2013 depending on your project phase and existing results.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

Non-binding grid connection application<\/h3><\/div><\/div><\/div>\n\n

The preparation of the non-binding grid connection application (grid registration) ensures that your project is correctly addressed to the responsible grid operator early on and that you receive reliable initial feedback on the next steps. Upon request, we can also provide further technical support \u2013 including tracking the grid application process and coordinating with the grid operator. <\/p>\n
