4×5.0 MWh
≈ 20 MWh nominal20ft liquid cooled plate containers. Compact delivery scheme; confirmation of ≥15 MWh useful AC energy per 6 kV is required.
Visualization of design execution. The number and arrangement of identical modules are determined by the working design.
The main project according to the original technical specifications
Project BESS 5 MW / ≥15 MWh usable AC energy
Project article: SNEE-5000-3H-LFP
Container LFP complex: approximately 20 MWh nominal capacity for guaranteed output of at least 15 MWh useful AC energy on side 6 kV.
Price under review
There is a comparison of factory offers for architecture 5 MW / about 20 MWh nominal. The final price is fixed after guaranteeing ≥15 MWh useful AC energy for 6 kV, choice of cooling, logistics and Russian installation.

Proposed factory architectures
Two options for 20ft LFP containers
Status: preliminary technical study. The exact model, number of containers and guaranteed energy are fixed in the technical and commercial proposal and the contract.
5 × 4.2 MWh
≈ 20.9 MWh nominal20ft liquid cooled immersion containers. Provides greater energy reserves; the final choice is made after calculating losses, resource and cost.
Acceptance criterion
15 MWh is measured at the 6 kV point of interconnection
The usable energy includes the operating range of the SOC, battery, PCS and transformer losses, HVAC auxiliary needs, temperature reduction and the agreed degradation margin. The nominal capacity of containers in itself does not confirm the fulfillment of the technical specifications.
Compliance with the original technical specifications
Not just a battery container, but a single energy complex
The parameters below have been transferred from the main text and appendices of the technical specifications. The final values are confirmed by the manufacturer's design and proposal.
Power conversion
Bi-directional PCS, DC cabinets and battery strings with BMS coordination.
Guaranteed issue
Full design power continuously, after an overnight charge of up to 8 hours.
Network integration
packaged transformer substation, ATS, relay protection and synchronization by phase, voltage and frequency.
Climatic version
packaged transformer substation UHL1 and engineering container systems for work on industrial sites.
Battery operating range
LFP, 10-90% SOC range, monitoring every storage tier.
Cyclic resource
At least 3000 cycles with a residual capacity of at least 60% of the initial one.
Contents of the project supply
All subsystems provided for in the technical specifications
packaged transformer substation can be replaced with a transformer as part of the BESS module, if this is confirmed by the design solution.
Cumulative part
LFP strings, BMS, parallel string logic control and DC cabinets.
Power transformation
Bidirectional PCS, protection, metering and power addition mode when load threshold is exceeded.
packaged transformer substation 6 kV
Transformer, one-way service panel, automatic transfer switch, relay protection and automation and auxiliary power supply.
Engineering systems
Heating, air conditioning, lighting, auxiliary needs, addressable fire alarm.
Control and SCADA
Local control system, event archive and exchange via Modbus and IEC protocols with the upper level.
Project and documentation
Detailed design, drawings, passports, certificates, spare parts, factory acceptance and training.
Budget update
Calculation 5 MW / about 20 MWh nominal
The previous guideline of 449.73 million rubles was formed from a base of $3.5 million and was saved only as an early budget estimate. Factory prices are currently being requested for increased capacity and different cooling systems.
The final budget will include confirmed FOB/DDP, component classification, 22% VAT, logistics, certification, Russian installation and commissioning. This is not a public offer.- Early budget estimate
- RUB 449.73 million
- Nominal capacity
- ≈ 20 MWh
- Useful energy for 6 kV
- ≥ 15 MWh
- Final price
- after the technical and commercial proposal
- Status
- under review
Scalable versions of HELIKOR
1 and 2 MW - not separate positions of the original technical specification
These are commercial options based on the same architecture. Their price is calculated separately taking into account the higher share of fixed project costs.
Design package according to technical specifications
Request a confirmed price and deadline
Together with commercial proposal we will fix the number of containers, brands of cells and PCS, single-line diagram, packaged transformer substation 6 kV, production schedule and delivery conditions.
