How battery-analytics-pro computes Romanian BESS revenue and ROI
This page consolidates the data lineage, calculation logic and regulatory backing for every number produced by the platform. It is intended for investors, lenders and counterparties performing due diligence on a Romanian BESS project.
All revenue projections are anchored on public market data. Coverage windows are pulled live from /api/v1/data/manifest where available; otherwise the fallback range is shown.
Hourly closing prices from the Romanian day-ahead exchange. Drives all PZU arbitrage simulations.
Public capacity/activation history for aFRR and mFRR products. Pay-as-bid settlement since ANRE Order 60/2024 (2024-10-01).
Daily RON/EUR reference rate from the National Bank of Romania, used for FX hedge cost modelling.
Tariff coefficients and storage exemption parameters from ANRE orders 56/2025, 60/2024 and 127/2021.
Chronological, SOC-aware dispatch over the day-ahead curve. We brute-force the optimal (charge_start, discharge_start) pair across all 24×24 candidates, respecting battery capacity and SOC bounds. AC round-trip losses are split symmetrically as √η on both charge and discharge legs.
profit = Σ (P_disch · √η · price_disch) − Σ (P_charge / √η · price_charge)
optimal = argmax over (h_charge, h_discharge) ∈ {0..23}²Capacity revenue is pay-as-bid since ANRE Order 60/2024 (2024-10-01). Activation revenue is the product market_share × market_mwh, capped at the battery's daily energy throughput so we never claim more energy than physically deliverable.
R_capacity = P_MW · hours · availability · price_capacity_pay_as_bid
R_activation = min(market_share · market_mwh, P_MW · 24 · cap_factor) · price_activation
R_total = R_capacity + R_activationAmortizing PMT loan, calendar + cycle fade on usable capacity, augmentation CAPEX in years 5 and 10, FX hedge cost on RON revenue, DSCR covenant flag, capacity-price compression with a regulatory floor, and a PICASSO go-live cliff that compresses pre- and post-launch capacity prices independently.
PMT = P · r / (1 − (1+r)^−n)
SOH(t) = 1 − cal_fade · t − cycle_fade · cycles(t)
DSCR(t) = CFADS(t) / debt_service(t) // covenant if < 1.20
P_cap(t) = max(P_cap_0 · (1 − comp_rate)^t, P_floor)Law 123/2012 Art. 66³ combined with ANRE Order 56/2025 grants storage operators an exemption from grid tariffs on energy stored and reinjected. We model this as an avoided-cost stream over reinjected MWh, conditional on the tariff-exemption metering compliance gate being qualified.
R_exemption = MWh_reinjected · (T_grid + T_system + T_distribution_avoided)source_kind: unverified_snapshot
Inputs are public market snapshots collected from OPCOM and Transelectrica. They have not been independently audited or counter-signed by the issuing body, so they are suitable for scenario analysis but not for settlement-grade evidence.
settlement_grade: false
Outputs are scenario projections, not bankable settlement proof. A lender expecting term-sheet-grade numbers must reproduce these calculations against signed DAMAS extracts and audited project-specific operating data.
