Measurement, land, engineering and trading, delivered turnkey

Every service is available standalone. Most clients start with a measurement campaign and stay for the rest of the project.

A 30-day met mast project

Signature to first data in one month. Design, fabrication and logistics run in parallel so the crew is on site by day 15 and the mast is transmitting by day 30, with four witnessed quality gates on the way.

    Every service is available standalone. Most clients start with measurement and stay for the rest.

    Power performance testing

    Independent verification that a turbine produces what its warranted power curve promises. We test to IEC 61400-12-1 with a met mast or remote sensing device, and to IEC 61400-12-2 with nacelle anemometry.

    Questions we hear most

    If yours is not here, a project engineer will answer it directly.

    How long does a bankable measurement campaign take?

    Twelve months of continuous data is the usual minimum for lenders, so most campaigns run 12 to 24 months. Permitting and fabrication overlap, and the mast is live and transmitting within 30 days of contract signature.

    Do you work outside India?

    Our delivery focus is India, from Kutch to Tirunelveli, with in-house crews and state-level partners for land, permits and logistics. Campaigns outside India are taken on case by case with the same engineering standard.

    Can you take over an existing mast or dataset?

    Yes. We audit the installation and data, recalibrate or replace sensors where needed, and bring the campaign onto the Vista Data Portal so historical and new data sit in one traceable record.

    Who owns the data?

    You do. Raw and cleaned datasets are delivered in open formats with a full audit trail, and remain available on the portal after the campaign closes.

    What is included in the turnkey scope?

    Anything from measurement alone to measurement plus land acquisition, permitting, owner's engineering, power performance testing and trading advisory. Scope is modular and priced per stage.

    How do you price a mast campaign?

    Supply and installation is a fixed price per mast based on height, structure and site logistics. Operation is a monthly fee with a data-recovery guarantee. Share the site and height and we will scope it within two working days.
