Grid connection
with no dead ends

Nobody can tell in advance whether the grid has free capacity – the grid operator decides only in its statement on the application and allocates capacity in the order of complete applications. So we prepare the application to pass the first time and file it as early as possible.

WHAT WE HANDLE FOR YOU

From the site check to the connection contract

For generation and consumption, with EG.D, ČEZ Distribuce and PREdistribuce.

01 Site check What can be found out in advance: land, zoning plan, protection zones, the nearest lines and stations, the likely voltage level and indicative connection options. Within 3 working days.

02 Grid connection application A complete submission under the grid operator's rules: site plan, single-line diagram, technology data, landowner's consent. An incomplete application is returned and loses its place in the queue – ours are not returned.

03 Statement and contract Communication with the grid operator, additional documents, capacity reservation and deadline tracking up to the connection contract.

04 Connection conditions in the design Disconnection point, grid protection, metering, dispatch control and communication, power quality – built into the design so that commissioning passes without rework.

05 Documents for operation For the Energy Regulatory Office and for the first parallel connection.

06 For installers We also prepare applications and documentation for installers' contracts, so they can focus on the installation.

HOW THE CONNECTION WORKS

Four steps to the contract

Capacity is allocated by the date of the complete application – your place in the queue is what matters most.

01 Site check What we know about the site in advance – and what only the grid operator decides.

02 Application A complete submission to the grid operator, with all attachments the first time.

03 Statement and contract The grid operator assesses the grid, confirms or adjusts the capacity and connection point and sets the conditions. Once the contract is signed, the capacity is yours.

04 Design and construction We build the conditions into the documentation; after completion we prepare the documents for commissioning and the first parallel connection.

WHAT TO WATCH OUT FOR

Four things that cost time

Order of applications Capacity is allocated by the date of the complete application. A missing attachment means the application is returned and loses its place.

Reserved capacity Apply for the capacity you will really use. The grid operator may cancel an unused reservation after some time, and larger capacities require a deposit.

Voltage level The grid operator may require a medium-voltage connection – and therefore your own transformer station. Allow for it in the budget and the schedule.

Every grid operator is different EG.D, ČEZ Distribuce and PREdistribuce differ in their requirements for the disconnection point, metering and communication. We know them from more than 200 projects.

FREQUENT QUESTIONS

What people ask us

Can I apply for a connection before I have a design?

Yes, and that is the right order. The application needs only a site plan, a basic diagram and technology data; the detailed design follows the grid operator's conditions.

How long does connecting a battery storage system take?

The grid operator's statement alone has a deadline set by the connection decree (roughly 30–60 days). The whole path from application through design, permits and construction to commissioning is much longer – for a storage system usually a year or more, depending on the capacity, the site and whether the grid operator has to reinforce the grid. That is why we file the application right at the start.

What if the grid operator refuses the connection or reduces the capacity?

We propose a change to the plan: lower capacity, limited export to the grid, a different connection point or a medium-voltage connection. Most refusals can be resolved.

Do you handle connections for installers too?

Yes. We prepare applications and documentation for installers' contracts, so they can focus on the installation.
