From energy asset to actionable proof.
WATTii turns your asset data into traceable proofs prepared for verification, for your decisions, reports and commitments.
A common 7-step process
A robust, transparent framework designed for reproducibility to turn your data into documented evidence.
WATTii expert agents control data, recalculate indicators, detect anomalies and prepare verification. Sensitive steps remain subject to logged human validation.
Define the scope
Delimitation of assets, boundaries and calculation rules.
Connect the sources
IoT sensors, meters, systems and platforms connected.
Qualify the data
Automated controls, anomaly detection, completeness assessment and preparation for human review.
Calculate performance
Methodologies mapped/aligned, subject to validation, with emission factors and normalization.
Create the proof passport
Sealed, timestamped proof; any later modification is detectable in the audit trail.
Calculate the WTS
Calculate WTS units under the versioned BP13 methodology. Any issuance requires logged human approval and a uniqueness check. The log retains actor, date, version, scope and reason.
Monitor and report
Dashboards, alerts and APIs to manage and communicate.
Sensitive steps remain subject to logged human validation.
Issuance is separate from calculation. The issuance log retains actor, date, version, scope, reason.
A two-axis proof model
Data nature and assurance level are assessed independently: a sensor can be miscalibrated, while calculated data can carry a high recorded assurance status. The Proof Score does not determine the assurance level.
Five separate methodology objects
Each object keeps its own unit, source, version and status. They are never merged into one field, badge or status.

Proof Score
The Proof Score is a 0-100 index describing evidence completeness and documentary quality. It is separate from WTS quantity and the assurance level, which it does not determine.
7 control criteria document evidence completeness and documentary quality. They do not determine the assurance level shown in Axis 2.
Provenance
Is the source identified and controlled?
Integrity
Is the data complete and sealed?
Metrology
Is the sensor appropriate and calibrated?
Temporality
Does the granularity fit the use case?
Method
Is the calculation versioned and designed for reproducibility?
Review record
Are review actor, date and evidence documented? This criterion does not set the assurance level.
Uniqueness
Is double counting prevented?
BP13 calculation framework
A WTS is a quantified energy-evidence unit calculated from eligible energy under the versioned BP13 methodology and recorded in the WATTii registry. It is distinct from the Proof Score, the assurance level, avoided tonnes of CO2 and economic value.
Formulas
- P_ref = P_trace + (c_ref × P_CO2) # c_ref = 0.75 tCO2e/MWh
- P_f,z = P_trace + (c_f,z × P_CO2)
- k = P_f,z / P_ref
- N_WTS = E_eligible × k
- V_est = E_eligible × P_f,z
Blocking rules
- Use full decimal precision with no intermediate rounding. Round only for display.
- The same currency is used for P_trace, P_CO2, P_ref, P_f,z and V_est.
- WTS quantity (N_WTS) and k do not depend on the Proof Score or the assurance level.
- Calculation and issuance are separate statuses. Issuance requires logged human approval and a uniqueness / double-counting check.
Reference fixture
Display values from the versioned BP13 reference fixture. Display rounding is for presentation only; the computation chain uses full decimal precision.

Indicators designed for reproducibility, based on a documented methodology
WATTii relies on published, transparent methodologies mapped/aligned, subject to validation.
Documented methodologies
Drawing on certain components of ISO 14064 and the GHG Protocol (mapped/aligned, subject to validation).
Complete traceability
Every data point, calculation and rule is documented and auditable.
Designed for reproducibility
The same inputs and the same versioned rules are designed to produce the same documented result.
Audit mapping
Evidence is mapped/aligned, subject to validation. Mapping to review requirements does not promise a regulatory result.
