What we measure

Wind is the asset class where estimates hurt most. A turbine’s output depends on wind speed, direction, air density and the availability of the machine itself, and a single disputed month can stall a refinancing. Zephyra reads each turbine at the nacelle — power, rotor speed, pitch, yaw — and pairs it with met-mast and satellite atmospheric data.

The result is a per-turbine, per-interval record of what the machine produced and what the wind would have allowed.

How it works

Field units are rated for two decades in the nacelle, from Arctic onshore sites to North Sea platforms. Readings are signed at source and committed to the ledger over a resilient link, so a lost backhaul never becomes a lost interval.

Availability, curtailment and wake losses are attributed automatically, giving operators a defensible answer for every megawatt-hour that did not reach the grid.

What you get

Audited output every lender accepts without a side letter. Curtailment you can see, attribute and negotiate. And a fleet-wide record that makes a 640 MW portfolio as legible as a single turbine.

Capabilities

What comes with it

01

Nacelle-level sensing

Power, rotor speed, pitch and yaw read at every turbine, rated for twenty years in the field.

02

Atmospheric pairing

Met-mast and satellite data alongside each reading, so lost production is attributable to wind or machine.

03

Curtailment attribution

Every megawatt-hour that did not reach the grid is assigned a cause, a turbine and an hour.

04

Offshore-ready links

Resilient backhaul with store-and-forward, so a dropped connection never becomes a missing interval.
