Industrial battery storage
Energy where and when you need it
Design and turnkey installation of industrial lithium-ion battery energy storage (BESS) systems. HUPX intraday arbitrage, peak demand reduction, reverse-power protection, capturing surplus solar generation — optimised for your consumption profile.
Value creation
How does battery storage create value?
The value of industrial battery storage depends on the type of electricity contract. It generates savings through different mechanisms for fixed-price and spot-price clients.
Spot (HUPX) contract — spreadThe difference between the most expensive and cheapest hour within a day — the source of arbitrage.More in the glossary →
- •Intraday arbitrage: charging during the cheap midday hours (solar price depression), discharging into the expensive morning and evening peaks. The HUPX intraday price difference is the engine of value creation.
- •Capturing surplus solar: the storage catches the solar clipping (free charging) and releases it during expensive peak hours.
- •Peak demand reduction: lowering the capacity charge by smoothing the peaks.
Fixed-price contract
- •Capturing solar clipping: the storage catches the surplus solar generation (free charging) and returns it into the fixed-price consumption — this is the main value-creating mechanism.
- •Peak demand reduction: reducing contracted capacity is a source of savings available to fixed-price clients as well.
- •No energy arbitrage: a fixed price means no intraday price difference and no spread. Arbitrage is ruled out.
Industrial energy prices
What makes up the industrial electricity price?
The industrial electricity price consists of two main components, and battery storage affects both.
The commercial fee (energy fee) includes the unit energy price — identical in every hour under a fixed contract, or varying quarter-hourly with the HUPX day-ahead price under a spot contract — plus the monthly-varying KÁT/premium levy (0–11 HUF/kWh, higher in summer; this varies even under a fixed-price contract), along with excise duty and the energy efficiency contribution.
The system usage charge consists of a volumetric charge (transmission 3.39 HUF/kWh plus distribution, from 1.98 to 22.20 HUF/kWh depending on voltage level; 11.78 HUF/kWh in total at medium voltage) and a contracted capacity charge (around 15,924 HUF/kW/year for a medium-voltage industrial client). These charges are identical under fixed and spot contracts. Source: MEKH 2026 distribution tariff table.

The only variable component even under a fixed-price contract — trackable month by month.
Contracted capacity charge — peak shavingPeak demand reduction: the BESS smooths peak load, lowering the contracted capacity charge.More in the glossary →
Battery storage reduces peak demand and therefore the contracted capacity — a direct saving.
Design approach
Simulation-based sizing
We do not work from templates. Using our own simulation engine we optimise the system on your real consumption and price data.
Quarter-hourly resolution
35,040 intervals per year, with the energy balance calculated for each. No averaging, no annual estimate — the real consumption profile determines the optimum.
Fixed vs. spot modelling
We handle both contract types with separate logic: HUPX-based arbitrage optimisation for spot clients, solar clipping capture and peak demand reduction for fixed-price clients.
Joint PV + BESS optimisation
When solar and storage are sized together, the two assets compensate for each other’s weaknesses — for spot clients this is the strong combination.
HUPX market price data — DAMDay-ahead market: the HUPX next-day market, the settlement basis for spot contracts.More in the glossary →
Built-in HUPX day-ahead reference prices at 15-minute resolution. Arbitrage potential can be calculated in advance, even without the client’s own price data.
Reverse-power protection
Reducing reverse-power exposure is a valuable side effect of battery storage — particularly with a large solar system and low base consumption.

Annual savings, cycle count, payback period, CO₂ savings — every figure from the simulation run in one place, in exportable format.
Applications
Where does it create the most value?
Manufacturing plants
Steady, high base consumption plus a spot contract is the ideal BESS profile. One to two full cycles per day.
Logistics centres
Cold stores, EV chargers, variable load — peak demand reduction delivers the largest saving here.
Food industry plants
Cooling load plus the summer KÁT peak means higher prices exactly when the solar system generates. Storage optimises this.
Alongside existing solar
If the PV system clips (generates surplus), the storage catches it — free charging, discharged into the consumption peak.
Jedlik grant winners
The Jedlik programme primarily supports battery storage. Our simulation helps size the planned system.
Sites with reverse-power limits
Has the distribution operator imposed a reverse-power limit? The storage absorbs the surplus — no generation is lost.
Financing
How do you finance the investment?
Corporate tax incentive — tax incentiveThe corporate income tax energy efficiency incentive (§22/H), claimable over six years.More in the glossary →
The BESS investment is deductible from corporate income tax over six years. It can be combined with the Jedlik grant up to the GBER ceiling.

Energy Infrastructure as a Service: we provide the funding, you subscribe. The service fee is lower than the savings.
