storage
Energy stored exactly where it's needed. Storage for businesses, agricultural sites and the utility scale – including grid connection.
240+ MWhof storage in our projects
LV & MVconnection and transformation
Study → as-builtall documentation stages
WHAT WE DESIGN
The whole storage system in one set of documents
Equipment, grid connection and civil works. Each part builds on the next.
01
Study
Where the storage can stand and how it connects. Options and payback.
02
Equipment layout
Layout of battery containers, inverters and transformers on site.
03
3D visualisation
The storage system in 3D before it is built – for the investor and the authorities.
04
Equipment foundations
Foundation drawing and documents for the foundations.
05
MV connection
Transformer stations, MV switching stations and transformation.
06
Cable routes
LV and MV cables on site and to the point of connection.
07
Diagrams and switchboards
Single-line diagrams, switchboards and metering.
08
Lightning protection
Risk management, air-termination system and earthing.
09
Surge protection
Protection of equipment on the LV and MV side.
10
Calculations
Cable sizing, voltage drops and short-circuit conditions.

WHY NOT WAIT
Grid capacity is allocated in order of applications
Whoever has the documentation and application ready first is in a better position. Every month of delay can mean worse connection terms.
Order of applicationsThe grid operator assesses connection applications one by one, based on free grid capacity.
Subsidy deadlinesSubsidy calls have fixed deadlines – the documentation must be ready before them.
Site check within 3 daysIn three working days you know whether it makes sense to go on.
SITE CHECK
Can you build on the site?
Send us the plot numbers and the required power. Within 3 working days of confirming the details, you know what stands in the project's way. If you then commission the project, we deduct the cost of the check from the project price.
Zoning plan
Nature protection – protected landscape areas and Natura 2000
Agricultural land protection
Flood zones
Protection zones and utilities
Indicative grid connection options
What we need from you
Cadastral area and plot numbers
Required power or capacity
Purpose – power plant, storage, or both
TO GET STARTED
A few details are enough
Site – cadastral area and plots
Required power and capacity
Purpose – self-consumption, energy trading, ancillary services
Existing site connection, if the storage sits behind the meter
Selected technology, if you already have it
Grid operator's statement, if you already have one
Have solar PV? We'll design storage for it.
