Public Methodology
Calculation chain, conventions, capture metrics, storage physics, information sets and inclusion rules.
Calculation chain
approved inputs → validation → physical profile or dispatch → eligible cashflows → normalisation → publication
Conventions
- Market: MIBEL.
- Bidding zone: Spain (ES).
- Currency: EUR.
- Prices: EUR/MWh.
- Resolution: finest reliable interval supported by the source and applicable rules.
- Calculations use full precision; rounding occurs only for display.
Capture metrics
CapturePrice = Σ(Pₜ·Qₜ) / Σ Qₜ
CaptureRate = CapturePrice / BaseloadPrice
GrossRevenue = Σ Pₜ·Qₜ
Storage
SOCₜ₊₁ = SOCₜ + ηc·Chargeₜ·Δt − Dischargeₜ·Δt / ηd
The reference BESS uses 90% round-trip efficiency. Where efficiencies are symmetric:
ηc = ηd = √0.90
No double counting
All markets share one physical state. The same MW, MWh, state of charge or grid capacity cannot be sold twice.
Information sets
| Code | Meaning |
|---|---|
| OBS | Observed result. |
| PF | Perfect foresight; an analytical upper bound. |
| DTI | Decision-time information only. |
| FWD | Forward scenario, not a historical benchmark. |
| CUSTOM | Project-specific analytics, not a public benchmark. |
Inclusion
A revenue component is included only when eligibility, observable inputs, market depth, settlement treatment and no-double-counting controls are approved.
Protected IP
Public disclosure includes economic meaning, material parameters, sources, equations, constraints, judgement and limitations. Production source code, credentials, schemas, solver tuning, security controls and proprietary forecast calibration remain confidential.
