Auditable end to end, from instrument to certificate.

Our Process

Scientific Credibility to Corporate Energy Action

Five layers of measurement, from the turbine nacelle to the atmosphere above it — so every claim you publish is traceable back to an instrument reading.

01.

Utility-Grade Observation Systems

Met masts, LiDAR, inverter telemetry and satellites track every megawatt-hour at the source.

02.

World-Class Resource Forecasting

We pair ground-truth data with real-time atmospheric measurement — the same methods behind the WMO’s State of the Global Climate reporting.

03.

Integrated Algorithmic Processing

High-frequency data is analysed at every stage — removing estimation bias and turning raw signals into decision-ready insight.

04.

Ledger-Secured Traceability

Every metric is verifiable, audit-ready and tamper-proof, so certificates of origin hold up to regulatory scrutiny.

05.

Built for Scale and Complexity

From a single wind farm to a continental portfolio, Zephyra adapts to your data infrastructure.

Renewable Power

We turn the energy around us into power you can rely on.

Built for Energy Operations that Need Proof

Verified generation data matters most where capital, compliance and reputation meet. For these operators a measured megawatt-hour isn’t just a number — it is proof of performance and environmental leadership.

Our Technology

Scientific Rigor. Commercial Precision. Unmatched Trust.

The first to bring atmospheric-based digital MRV to corporate energy accounting — turning generation data into verified insight.

Atmospheric-Based rMRV

Measured at the source, not modelled after the fact.

We pair nacelle and inverter telemetry with real-time atmospheric measurement, the same methodology trusted by leading climate institutions.

Ledger Technology

Every data point traceable, tamper-proof, verifiable.

Built on an append-only ledger, our system makes each reading auditable end to end — from instrument to certificate of origin.

No spreadsheets. No guesswork.

Just Real, Measured Insight Delivered with Integrity.

Quantify output, prove performance, and earn the trust of regulators, offtakers and the communities you serve.

Norvind cuts curtailment 31%

A 640 MW onshore fleet across northern Norway was losing output to curtailment nobody could attribute. Nacelle-level measurement made every lost megawatt-hour traceable to a turbine and an hour.
