Solution
Connecting a site without waiting for grid upgrades
In constrained grid nodes, a capacity increase takes years. The storage charges within the allocated capacity and covers peaks above it, so the site can start earlier and avoid paying for capacity it needs only a few hours a day.
Key figures
up to 4 months
to fulfil grid connection conditions when spare capacity exists, for sites up to 670 kW

grid company practicehours, not megawatts
storage covers peak hours, not the entire load
calculation principleWhy a site waits for the grid
Capacity shortage in the node
There is no spare capacity at the substation, and the grid connection conditions require an upgrade with a long lead time.
Peaks shorter than a day
The site needs high power only a few hours a day: charging stations, equipment starts, seasonal load.
Expensive new capacity
The grid connection fee grows with capacity, and it has to be paid up front.
Business deadlines
A warehouse, plant or data center has to start now, not after the grid company finishes construction.
Solution
How it works
The storage acts as a buffer between the grid and the load: grid consumption does not exceed the allocated capacity, and the battery supplies the difference.
- Profile-based calculationWe determine how much power and for how many hours is missing, and size the energy and power of the storage.
- Charging within the limitDuring low-load hours the storage charges without exceeding the allocated capacity.
- Covering peaksWhen the load exceeds the limit, the storage supplies the difference. A power limiter prevents exceeding the grid capacity.
- After the upgradeOnce the grid is reinforced, the storage stays on site and moves to lowering capacity charges and providing backup.
- primary source
- backup
- unstable
- not available
Grid consumption does not exceed the allocated capacity.
When storage beats a capacity increase
| Situation | Without storage | With storage |
|---|---|---|
| Peak of 2-4 hours a day | paying for capacity sized to the peak | capacity sized to the average load, the battery covers the peak |
| Grid upgrade of 2-4 years | the site waits or runs on gensets | start-up within the allocated capacity |
| EV charging stations | high capacity for short sessions | on-site buffer, the grid sees a flat load |
| Seasonal load | capacity sits idle most of the year | storage works all year round lowering charges |
Grid connection lead times are based on current rules and grid company practice in Russia as of 10.2026. The use of storage is agreed with the grid company under the site's connection conditions.

Peak shaving and load shifting
Discharging during peak hours lowers billed capacity; charging at night lowers the energy bill.
