Industrial solar plant for self-consumption

Calculate your plant's payback → +380 67 104 94 91

An industrial solar plant reduces the electricity bill through self-consumption: during the day the business consumes its own generation instead of buying from the grid at the full tariff. We are an electrical engineering company with our own design department and our own in-house manufacturing of switchgear 0.4–35 kV, so we size the plant for your electrical facility — the grid, the connection point and the load schedule — not "for the roof."

Who benefits

The greatest effect is for businesses with stable daytime consumption, when generation matches the load:

  • manufacturing, workshops, metalworking;
  • agribusiness, greenhouse and farm operations;
  • warehouses, logistics, cold storage facilities;
  • retail and services with a daytime peak.

Solutions by capacity

30–50 kW
rooftop and small ground-mounted plants; three-phase connection at 0.4 kV.
100–200 kW
manufacturing and agricultural facilities with significant daytime load; often combined with energy storage (BESS) for peak shaving.
500 kW – 5 MW
industrial sites; connection is typically at 6–35 kV via a dedicated transformer substation (KTP) and relay protection (the exact voltage class is determined by the grid operator in the technical specifications).

Examples of plants by capacity — with indicative parameters; the exact configuration is calculated for your facility.

What this gives your business

  • a lower electricity bill through daytime self-consumption;
  • predictable energy costs for years ahead;
  • backup power for critical loads during outages (with BESS storage);
  • surplus energy can be fed into the grid under the active consumer model (net-billing) at the market price — this is compensation, not fixed income.

We calculate the payback period individually for your load schedule and tariff. In projects with a high share of self-consumption, the calculated period is around 3–4 years; this is an indicative modeling result, not a guarantee, and depends on the share of self-consumption, the tariff and the market price for the surplus.

What we handle in the electrical engineering part

Most of a plant's engineering risk lies precisely in the electrical part: how it works together with your grid. Mistakes here are the most costly — incorrect protection settings or transformer overload when feeding surplus back. We design and carry out this part ourselves:

  • load and short-circuit current calculations;
  • anti-islanding protection — at the inverter level (EN 50549 / IEC 62116) and relay protection of the connection at 6–35 kV;
  • checking the transformer under reverse power flow — its loading when feeding surplus back and the voltage rise on the busbars;
  • in-house switchgear 0.4–35 kV (KTP, switchgear, panels, ATS) built for the project;
  • the connection design and support in coordinating it with the grid operator (DSO).

We select and supply the panels and inverters (Tier-1), while the switchgear 0.4–35 kV we manufacture ourselves.

Types of industrial solar plants

  • Grid-tied — for self-consumption with surplus feed-back; the greatest effect with daytime load.
  • Hybrid with storage (BESS) — stores the daytime surplus for the evening and provides backup during outages.
  • Rooftop or ground-mounted — depending on the roof's load-bearing capacity and available land; for production and warehouse buildings the roof is often the optimal choice.
Scope of service

What the work includes

  • Audit of consumption and the connection point — the plant is sized for your actual load schedule.
  • Electrical design: loads, short-circuit currents, relay protection, transformer check.
  • In-house switchgear 0.4–35 kV (KTP, switchgear, panels, ATS) for the specific project.
  • Tier-1 panels and inverters: selection, supply, installation.
  • Grid connection: design and support in coordinating with the grid operator (DSO).
  • Commissioning, testing by our own ETL, warranty and service support.
Questions & answers

FAQ

What is the benefit for a business from its own solar plant?
The main benefit is a direct reduction of the electricity bill through self-consumption: during the day you consume your own generation instead of buying from the grid at the full tariff. The amount of savings depends on the consumption profile — the share of daytime load, the plant's capacity and current energy prices. The greatest effect is for businesses with stable daytime consumption (manufacturing, warehouses, cold storage facilities, agribusiness, retail). In addition, the plant provides partial energy independence and predictable costs for years ahead. We size the capacity for your actual load schedule, not "for the roof."
What is the payback period of an industrial solar plant?
In projects with a high share of self-consumption, the calculated period is roughly 3–4 years, when most of the generated energy is consumed directly at the facility during the day. With lower self-consumption, the period is longer. This is an indicative modeling result, not a guarantee: it depends on the share of self-consumption, the tariff the savings are compared against, the market price for surpluses, and the business's operating schedule. That is why we design the plant for your actual load schedule and calculate the period individually for your facility.
What documents are needed to connect an industrial solar plant?
The basic package: technical specifications (TU) for connection from the distribution system operator (DSO/oblenergo), the plant design, a connection agreement and the related agreements for operating under the active consumer model, as well as installation of bidirectional metering. The exact composition depends on the capacity, the connection scheme and the specifics of the facility. As a design organization, we prepare the design documentation and handle the coordination with the DSO ourselves — you do not have to go through the various offices and gather the paperwork yourself.
Can surplus electricity be sold to the grid in 2026?
Yes, but under new rules. For new commercial plants, the "green" tariff no longer applies — it has been replaced by market mechanisms (auction / market premium) under Law No. 4777-IX, in effect since 11.03.2026. For businesses building a plant for self-consumption, the "active consumer" model (net-billing) applies: you consume your own energy, and the surplus is fed into the grid at the current market price (the day-ahead market, DAM). The market price changes daily, so selling the surplus is an additional component, not the main source of income; the economic case is built on self-consumption. We help arrange active consumer status.
Is an NKREKP license required for an industrial solar plant?
For most commercial self-consumption plants — no. An NKREKP license for electricity generation is required from 5 MW of installed capacity (or if there is an intention to sell the generated energy as a market participant). Smaller plants for self-consumption that sell surplus under the active consumer model do not need a generation license. The license-free threshold for energy storage systems (BESS) has also been raised to 5 MW (NKREKP resolution No. 789 of 26.05.2026). This is a reference point as of 2026 — we determine the specific scenario at the design stage.
What determines whether the protection works correctly and the transformer is not overloaded?
It depends on the engineering calculation of the electrical part, not on "default settings." Anti-islanding protection is provided by grid-tied inverters (per EN 50549 / IEC 62116), and at the 6–35 kV connection — by interface relay protection with settings matched to the actual short-circuit currents. The transformer is not overloaded if its capacity and operating mode are calculated with account for reverse power flow when feeding surplus back and the voltage rise on the busbars. Our electrical engineers design the plant together with its protection as a single system — on paper, before installation.
Can a solar plant be installed with batteries (BESS)?
Yes. Hybrid solutions with an energy storage system (BESS) allow the daytime surplus to be stored and used in the evening or during outages — this increases self-consumption and provides backup for critical equipment. Storage is especially worthwhile when the consumption peak does not coincide with the generation peak. The licensing threshold for storage has been raised to 5 MW. We size the BESS capacity for your load schedule so that the storage pays for itself rather than sitting idle — additional batteries increase both the effect and the capital cost.
Can a loan or financing be obtained for a solar plant?
Yes. In 2026, preferential financing programs for energy independence are available to businesses — including the state program "Affordable Loans 5-7-9%" and the EBRD support program (ESSF) with a grant component. Specific rates, limits and conditions depend on the program, the type of borrower and the partner bank, and change periodically — they should be confirmed with the bank at the time of application. We help prepare the technical and design part of the package (design, cost estimate, equipment specification) to meet the bank's or donor's requirements.
