GRID FLEXIBILITY / 3-SITE PORTFOLIO — 15 MW / 30 MWh PER SITE
What We Do
We build and operate a three-site portfolio of grid‑scale battery storage directly at Romania's border substations with Hungary and Ukraine. Each site delivers 15 MW / 30 MWh capacity, optimizing existing infrastructure — delivering maximum flexibility within grid constraints to charge on surplus and discharge on deficit.

Why Borders
Border nodes experience frequent imbalances driven by cross‑border trades, renewable intermittency, and grid stress. Placing storage at these substations intercepts imbalance at the source and captures high‑value balancing activations while avoiding deep‑grid upgrades.
How We Operate
- Balancing (TSO‑directed): We contract capacity with Transelectrica for stable €/MW·h availability and deliver energy on activation.
- Arbitrage (DAM/IDM): We selectively charge and discharge in day‑ahead or intraday windows with the best spreads.
About Battery.Network
Strategic Positioning at Energy Imbalance Hotspots
Our battery energy storage systems are strategically positioned near Romania's borders with Hungary and Ukraine — the country's largest energy imbalance zones. A significant portion of electricity delivered to Ukraine flows through this corridor, while substantial power imports arrive from Hungary via the western interconnection.
This geographic concentration creates frequent grid oscillations and large frequency deviations, driving high imbalance prices. The scarcity of local balancing resources in these border zones further amplifies market opportunities, making our BESS installations critical infrastructure for grid stability.
Technical Expertise & AI-Powered Trading
Beyond asset ownership, Battery.Network delivers comprehensive energy trading services through our proprietary platform. We offer:
- PZU & Intraday Arbitrage Trading — optimized execution for third-party assets
- AFRR/FCR Balancing Services — capacity reservation and activation management
- AI-Powered Market Analytics — machine learning algorithms analyze weather patterns, cross-border flows, and grid conditions to predict imbalances and optimize charge/discharge cycles
Our software continuously monitors real-time data — meteorological forecasts, import/export flows, renewable generation curves — to anticipate grid stress events. This allows us to position batteries proactively: charging during surplus periods, discharging during deficits, or holding capacity for high-value reserve payments.
Investor Value Proposition
When you invest in Battery.Network, you gain access to both premium infrastructure assets and our advanced trading know-how. We don't just deploy batteries — we maximize their revenue potential through intelligent, data-driven operations that capture value across multiple market segments simultaneously.

Strategy
Balancing Market (TSO-directed activations)
Every day, our 15 MW nodes are offered into the balancing market. Transelectrica pays a fixed €/MW/h for availability. When the system faces a deficit, we discharge; when there is surplus, we absorb. These activations generate additional €/MWh revenue on top of the availability fee. Located at imbalance-heavy border nodes, our probability of activation is high.
Day-Ahead and Intraday Arbitrage
Beyond contracted balancing services, we actively participate in DAM/IDM to capture spreads. The cheapest hours for charging are typically early morning (03:00–04:00), while peak discharging hours occur in early evening (18:00–19:00). This spread — often above €120/MWh — generates strong daily margins.
Hybrid Optimization
We combine both worlds. A majority of capacity is reserved for balancing to guarantee stable income, while a portion is allocated for merchant trading when spreads are profitable. This hybrid approach maximizes revenue while maintaining obligations.
Balancing Scenario
Technical (per site)
- ATR 15 MW
- Activation power % 66%
- Activation h/day 7.0 h
Market Inputs
- UP €/MWh €450
- Capacity €/MW·h €4.9

- Total €/month €—
Note: Scenario calibrated to our balancing base case (15 MW, 7 h/day at ~15% activation, €450/MWh sell vs. €120/MWh buy, €4.9/MW·h capacity). Adjust inputs if market conditions differ.
Profitability Simulation
Vision – Turning Volatility Into Value
We believe that the chaos of modern energy markets is not a threat but an opportunity. By positioning storage assets at strategic imbalance hotspots, we are able to convert market turbulence into structured, predictable returns. Our vision is to build a network of cyber-resilient storage nodes that stabilize Romania’s grid while generating market-leading profitability.
This vision is backed by three principles:
- Location is everything. Substations on the border with Hungary and Ukraine see constant swings due to cross-border trades and renewable intermittency. By placing our assets there, we intercept imbalance directly at its source.
- Hybrid revenue stacking. We combine the guaranteed income of balancing market capacity payments with the upside of active trading in the day-ahead and intraday markets.
- Scalability. Each 15 MW node is modular and replicable. The plan is to expand from an initial 45 MW to over 100 MW across Romania and neighboring regions.
Economics
The economics of Battery.Network are driven by high‑value imbalance activation and disciplined arbitrage. Live figures below are tied to the current Balancing Scenario assumptions.
- Export/day— MWh
- Export/month— MWh
- Energy €/month€—
- Capacity €/month€—
- Total €/month€—
Balancing forecast: €3,120,000 annual revenue, €663,258 energy cost, delivering €2,456,742 net profit after costs (per 15 MW / 30 MWh node).
PZU trading forecast: €2,766,978 revenue, €1,921,943 net profit (after costs), €0 incremental OPEX, 10,950 MWh energy volume.
Revenue Composition
- Balancing activations (energy): Exported MWh × UP price. Driven by activation hours/day and % of ATR committed.
- Capacity availability: ATR × 24 h × Capacity €/MW·h. Paid regardless of activation (subject to performance KPIs).
- Optional arbitrage: Opportunistic DAM/IDM trading can add upside when spreads justify cycling without jeopardizing reserve availability.
Current Assumptions
- ATR: 15 MW (ref: scenario ATR)
- Activation hours/day: 7.0 h
- Activation power: 66% of ATR
- UP price: €450/MWh
- Capacity price: €25/MW·h
Operating Costs
- OPEX (fixed): ~€0.25–0.30M/yr (service contracts, insurance, compliance, site ops).
- Augmentation: Modular cell augmentation around year ~8 to sustain usable energy and performance.
- Auxiliary: Site parasitic/aux loads minimized; telemetry and EMS costs included in OPEX.
Financial Metrics
- Payback: With €9M investment and €2.46M annual net profit, payback is ~3.7 years for balancing services.
- Debt serviceability: Strong capacity revenues support stable DSCR even in softer activation months.
- IRR sensitivity: IRR rises with activation hours and UP price; declines with price compression or lower activation.
Sensitivity
- High Activation: +2 h/day → Energy €/month increases materially; total €/month up accordingly.
- Low Activation: −2 h/day → Energy €/month decreases; capacity €/month anchors baseline.
- Price Compression: −€50/MWh on UP → Energy €/month down; revisit scenario to adjust activation strategy.
