Investment in Industrial Solar Power Plants

What you are buying: a generating asset, not equipment

Investment in an industrial solar power plant is not "panels on a roof." It is a generating asset that produces electricity for sale and returns invested capital through the cash flow from that sale. The project may have no self-consumption at all: the plant is built to sell kilowatt-hours, not to cover someone's electricity bill.

This changes the evaluation logic: you are not analyzing "savings" but revenue, cost of generation, market sale price, and the risk of that market — as with any infrastructure asset. For new industrial facilities the "green" tariff is closed, so the economics rest exclusively on market sales — it must be approached as an investor, not as a subsidy recipient.

Three sources of revenue for the asset

Merchant — sale on the DAM

the "day-ahead market": the plant delivers volume to the wholesale market through a licensed supplier/trader at the hourly market price. The most flexible, but also the most volatile, stream.

PPA / direct-line supply

a long-term bilateral agreement (10–20 years) "generator → offtaker-consumer" with a fixed price and volume. A PPA reduces price volatility for the contracted volume and significantly improves the project's suitability for debt financing (bankability). A separate mechanism for direct corporate PPAs in Ukraine is currently being implemented.

BESS — energy storage system

arbitrage (store during low-price hours, sell at peak) and a hedge against grid restrictions — when the dispatcher limits output, the energy is stored in the battery and sold in the evening.

A real project is almost always a combination: part of the volume under PPA for predictability, part on merchant for upside, BESS to smooth out price dips and restrictions.

Merchant revenue: why "average price × generation" is a myth

In simple terms: the sun generates during the day, when the market price is often lowest — so calculating revenue at "the average price" is incorrect. The DAM is hourly and volatile — within a single week of 2026 the price range varied by roughly 1.5 times (the base index for May 2026 was around UAH 5,069/MWh; in the first half of the year the price ranged from ~UAH 3,950 to ~UAH 6,930/MWh, per Market Operator data). The key point: a solar power plant generates during the day, when the price is often below average due to a surplus of sunlight — so revenue is calculated not as "average price × annual generation" but on the hourly capture profile (how much a kWh is worth specifically during your generation hours). The plant does not sell directly but through a supplier/trader, who takes on balancing — a separate cost item in the model.

Economics and metrics: what we calculate and how

Initial investment (CAPEX) is calculated on an engineering basis — from the BOM, i.e., from the equipment specification with current prices, rather than "$/kW out of thin air." The market benchmark for the specific cost of a turnkey ground-mounted solar power plant without storage in 2026 is approximately $550–750/kW; this is a market benchmark, not a price for your specific facility — the actual cost depends on the equipment, logistics, and site. In commercial proposals, all prices are quoted incl. VAT. The specific cost without BESS and the full cost of a hybrid system with storage are shown separately — these are different figures; maintenance costs (OPEX) are a separate line item in the model.

According to public market estimates for energy projects in Ukraine in 2025–2026, the yield is approximately 10–15% per annum in foreign currency, with payback of around 4–7 years depending on the sales scheme: shorter for a diversified profile (PPA + BESS services), longer and riskier on pure merchant. These are market benchmarks, not a guaranteed yield, and not a public offer — the figures for your specific facility may differ.

IRR, NPV, cash flow, and payback for your facility are calculated in a financial model built for the specific site — using the actual hourly DAM profile, CAPEX from the BOM, and the chosen sales scheme, with sensitivity analysis.

Key risks and how they are managed

DAM volatility and solar capture

daytime generation falls within the lower-price hours. Management: a share of volume under a fixed-price PPA, modeling on the capture profile.

Output curtailment

the dispatcher may limit output from renewable energy facilities to balance the power system. The hedge is BESS and "flexible connection," which in some cases makes it possible to avoid costly grid reconstruction; this mechanism is currently being implemented in Ukraine.

Connection cost and timeline

new NKREKP (National Energy and Utilities Regulatory Commission) rates apply from 01.04.2026. Grid connection can become a separate major CAPEX line item and a timing risk — it is built into the model from the outset.

Regulatory risk

changes to the transmission/distribution tariff methodology affect the economics. The model is built without relying on the closed "green" tariff.

Currency risk (FX) and debt financing

CAPEX is mostly in foreign currency, revenue in hryvnia. Banks finance not "pure arbitrage" but a structured Revenue Stack — diversified streams (arbitrage + ancillary grid services + balancing + PPA) rather than a bet on a single price.

Why LK Energy de-risks the project

LK Energy is a Ukrainian manufacturer of 0.4–35 kV switchgear equipment (its own factory in Odesa) and an EPC contractor for solar power plants: approximately 100 solar power plants built, with the flagship being an industrial 4.95 MW plant with an energy storage system (see the project →). For an investor, this translates into concrete advantages for the asset:

Site selection with available capacity

we find a site in the right location where there is available capacity at the substation at the connection point. This is often the main factor in project feasibility and cost.

Predictable CAPEX and timeline

estimate from the BOM, with key equipment (KTP, switchgear, RZA) of our own production: less currency and logistics dependency, control over price and schedule.

Single point of accountability

design + manufacturing + construction + service under one roof, with no gaps between contractors.

A financial model as the deliverable

not a presentation, but a working project model (IRR, NPV, cash flow, sensitivity) based on the actual DAM profile. A document you can take to the bank.

Next step — a calculation for your site

The general ranges here are for market orientation only; decisions are made based on the financial model of the specific facility. If you are considering a project from ~$600 thousand, we will estimate CAPEX from the BOM, calculate revenue on the hourly DAM capture profile, compare sales schemes (merchant / PPA / +BESS), and show IRR, NPV, payback, and sensitivity to risks. Provide the site parameters (capacity, location, presence of an offtaker-consumer, connection conditions) — you will receive a specific calculation.
