These reductions in uncertainty and bias improve the potential profitabil ity of a wind farm

through more certain wind resource assessment. Further, understanding of wind flow for wind

turbine performance through power curve measurements across the entire rotor diameter

to IEC 61400-12-1 is achieved.

THE EC ON OMIC BE NEF I TS

F INA NC IA L JUSTIF ICATI ON S F OR LIDA R S DURING DE VELOPME NTWind resource assessment determines

the long-term wind resource and flow

characteristics across the project site. Wind

turbine siting, specification and suitability

studies can then be performed. In addition

the long-term wind resource can be

calculated. This is all to ensure that accurate

annual and life-time energy yield predictions

can be made, including an assessment of the

uncertainty in such calculations.

ZephIR 300 delivers measurements at

heights across the entire rotor-swept area,

confirming hub-height resource as well as

wind shear, veer and turbulence across

the rotor. Shear extrapolation bias and

uncertainty are therefore greatly reduced.

ZephIR 300 improves flow model accuracy

through multiple spatially separated

measurement points on the site for model

verification and tuning. Advanced flow models

provide significantly improved horizontal

and vertical extrapolation of measured wind

resource, especially in complex and forested

terrain.

ZephIR 300 is re-deployable, portable and

does not require lengthy planning applications

before installation. Data can be collected

easily at multiple points on a site to provide

representative measured data for all turbine

locations and tuning / verification points for

flow models further reducing uncertainty and

ensuring the right turbine type is chosen.

DNV GL: C LEA R GUIDELINE S F OR ‘BA NKING’ ON REMOTE SE N SOR SDNV GL has been widely acknowledged as

a globally recognised technical authority on

wind energy for three decades. The company

has applied this authority to the emerging

field of remote sensing, specifically its use

in the context of the development and

financing of wind farm projects. Their analysis

notes that cup anemometers have been the

industry standard for measuring wind speed

at wind farm sites and therefore they must

be considered the benchmark against which

any alternative measurement device must be

compared.

STAGE 1STAGE 3

STAGE 2

WHAT D O THE BA NKS SAY?

DNV GL considers ZephIR 300 to be at Stage

3 under “benign” conditions - accepted for

use in bankable / finance-grade wind speed

and energy assessments with either no or

limited on-site met mast comparisons.

ZephIR was the first wind lidar system to

achieve accreditation at this level.

Limited validation of device against

conventional met masts over a range of

heights (50m – 120m), achieving a similar level

of accuracy in measurement.

Moving to formal wind speed /energy

assessments based in part on data from the

device, but only with site-specific validations

against conventional anemometry.

Realise the benefit of safer lifting

How? ZephIR 300 provides wind
