Industrial solar power plants for businesses — 30 kW to 5 MW, turnkey
LK Energy is an engineering-and-manufacturing company with its own switchboard factory: we design the electrical part of the plant and build switchboards and packaged substations (КТП) in-house. The entire electrical scope — design, equipment, installation, grid connection and service — in one pair of hands.
Who it's for
Energy-intensive businesses — to cut the electricity bill
On-site generation covers a significant share of your daytime consumption: you buy less from the grid at the commercial tariff. We size the plant to your real load profile, not “to the roof area”.
Investors — a site and capital for generation
We build and operate the plant on a turnkey basis. Return metrics (IRR, NPV, payback period) are modelled individually for the chosen sales model — this is a guideline based on market conditions, not a guarantee. Considering generation as an investment? More on the investor page →
Businesses where downtime is critical — a solar plant with storage
If a production stoppage means losses, we add a battery (BESS) sized for your critical load. We show honestly what exactly it covers, without promising full autonomy.
Why this works now
The electricity tariff for businesses is rising, while the “green tariff” for new commercial sites has been replaced by market mechanisms (net-billing). So the logic has shifted: the main benefit of an industrial solar plant is not “selling to the grid” but self-consumption. Every kWh generated and consumed on site is a kWh you did not buy from the grid.
Surpluses you export to the grid are compensated under net-billing (under a self-generation purchase-sale contract — an addendum to your electricity supply contract) — this is compensation for the value of the energy exported, not a fixed income. That is why we design the plant around your consumption profile, so that the maximum of your generation goes to your own needs.
The solution — what “turnkey” includes
We take on the entire electrical scope of the plant — from the calculation to the connection.
Typical configurations
- 30–50 kW — so your business keeps running during outages. Rooftop or a small plot for small and medium businesses; a backup-ready design — hybrid inverter or BESS + ATS — keeps critical lines powered when the grid is down. One contract for the entire scope.
- 100–500 kW — this is already a power facility: technical conditions, design documentation, a 10(6)/0.4 kV substation and grid connection. Manufacturing, warehouses, agriculture, retail — we handle the entire electrical scope in-house.
- 500 kW – 5 MW — energy-intensive enterprises and investment sites: full EPC scope from feasibility calculation to commissioning.
Why LK Energy
Our own switchboard factory
We build switchboards, packaged substations (КТП) and 0.4–35 kV distribution equipment ourselves. That means control over quality, timelines and price — no middleman markup and no “third-party” equipment in the most critical part of the plant.
Engineers of the entire electrical scope
We take on the hardest part — the entire electrical scope and the grid connection. One party accountable for all of the plant's electrical works: no need to stitch a project together from several contractors.
Scale and level of responsibility
6 MW (AC) of industrial solar plants delivered; the flagship is a 4.95 MW plant with storage, delivered in the Odesa region. Plus engineering experience on nuclear sites — the Chornobyl NPP (subcontract) and the Rivne NPP. This is a level of responsibility you can see in every switchboard.
Delivered projects
- Industrial solar plant 4.95 MW + storage, delivered in the Odesa region — a plant with an energy storage system. View the case
- Equipment for solar plants — switchboards and switchgear of our own manufacture on site. View
For designers: a typical КТП solution for solar plants — a DWG set of relay-protection diagrams on request.
Electrical engineering — why it's reliable
- Grid safety. Grid-tied inverters run with anti-islanding (ДСТУ EN 50549-1:2022 / -2:2022): if grid voltage disappears, the plant disconnects automatically — protecting the operator's personnel during work on the line.
- Switchboards and protection of our own manufacture. Compliance with DSTU standards, coordinated relay-protection settings, correct coordination on both the 0.4 and 10(35) kV sides.
- Reactive power and contracted capacity. We account for cos φ and reactive-power compensation, so the plant does not incur penalties and stays within the terms of your contract with the DSO.
- Grid connection at the site's voltage class — from 0.4 to 35 kV, depending on the plant's capacity.
What the work includes
- Design — a calculation tailored to your load profile, single-line diagram, working documentation, environmental impact assessment (EIA) if required.
- Equipment — 0.4 kV switchboards, packaged substations (КТП) and 10(6)/35 kV switchgear, relay protection — from our own factory. Solar panels and inverters — sourced from proven Tier-1 manufacturers.
- Installation — ground-mounted or rooftop: construction and electrical installation works.
- Grid connection — technical conditions, coordination with the operator (DSO), commissioning. We run the process from application to acceptance certificate.
- Service — commissioning, monitoring, warranty and post-warranty maintenance.
