Hybrid Solar Power Plant with BESS, 5 MW Capacity
General information
Hybrid solar power plant with BESS, 5 MW — composition and purpose
A ground-mounted energy complex: a grid-tied solar power plant of 5 MW plus a BESS storage system rated 5 MW and 20 MWh — the upper limit LK Energy takes on as general contractor. The package includes high-efficiency monocrystalline Tier-1 modules, inverters (Deye, Huawei, Solis), the storage unit, a step-up KTP/RP substation with the high-voltage section, and the metering, SCADA and monitoring systems.
Storage on this scale is not an option but the second half of the project: it smooths the daily generation profile, keeps critical loads supplied during outages within the batteries' reserve, and makes it possible to shift energy delivery in time. The plant is designed, manufactured and installed by one team: the switchboard equipment — KTP, RP and switchgear — is built at our own plant in Odesa, followed by electrical installation, commissioning and support with the grid connection. The typical delivery time is 5–8 months, from site selection to putting the plant into operation.
Price and CAPEX
The indicative cost of a hybrid solar-plus-BESS complex of this configuration is about $1,200/kW (example: $6,000,000 for 5 MW with 20 MWh of storage); the exact cost is calculated for the project, depending on the configuration:- Inverters (Deye, Huawei, Solis)
- BESS (CATL, BYD, Sungrow)
- Type of mounting structure
- KTP/RP/transformer
- Level of automation and SCADA
- Complexity of the grid connection (technical conditions)

KTP, RP, switchgear, high-voltage section
Design of KTP, RP and switchgear units and of high-voltage cable lines.BESS (energy storage)
The storage system within the plant smooths the daily generation profile, keeps critical loads supplied during outages (within the batteries' reserve) and makes it possible to shift energy delivery in time. The capacity and the converter rating are selected for your consumption profile and connection scheme.
Electrical installation works and EPC
The integrated EPC approach includes:- Installation of structures
-
Mounting the solar panels and their supports.
- Cable routes Laying the cables that carry the electricity.
- Inverter systems
- Connecting the inverters that convert direct current into alternating current.
- KTP/RP substations
- Installing the transformer substations that feed the energy into the grid.
- BESS integration
- Integrating the energy storage systems into the plant's scheme.
- Commissioning (PNR)
- Commissioning works.
- Putting into operation
- completion of the installation and putting the plant into operation.
