DATA ACCURACY AND AVAILABILITY Wind tunnel tests – the theoretical limits (unless the speed of light changes) Measurements in a high-specification wind tunnel confirm very close agreement over a wide velocity range

Measured line-of-sight (LOS) windspeed accuracy No calibration required. Determined by laser stability (~ 1nm) and quartz clock of DSP. Stability to better than 1 part in 1,000.

Wind speed determination confirmed by numerous trials R2 = 1.00 demonstrated in wind tunnel over 5 to 75 ms-1 range. R2 > 0.997 by correlation with Natural Power’s 90m calibrated met mast.

TECHNICAL ADVISORS / BANKS ENGINEERS DNV GL considers ZephIR 300 to be at Stage 3 under “benign” conditions accepted for use in bankable / financegrade wind speed and energy assessments with either no or limited onsite met mast comparisons. “ZephIR is very capable of providing high quality, 10 minute average wind speed and direction data at all heights well above traditional tall mast heights. Correlation is excellent to our IEC compliant mast and site. ZephIR can therefore be considered, in our initial opinion, to be used in a standalone application for wind resource measurements.”

“Our [ZephIR] results encourage development and integration of continuous wave wind lidar technologies in the area of active turbine control and improvement of wind turbine performance…. ZephIR has shown excellent reliability and data availability was very high throughout the measurement period.”

Natural Power considers that “ZephIR can be recommended as a primary wind measurement system for offshore wind farms. There is a significant and consistent body of evidence to support the use of ZephIR in offshore conditions as the sole data capture system” “As well being able to measure upwind at extremely short distances, no other lidar system is able to incorporate shear, turbulence and veer measurements to allow calculation of hub height and rotor equivalent power curves. The ZephIR DM is the only commercially available wind lidar device that satisfies our requirements …. and has provided a reliable, accurate and user-friendly solution throughout.” “This is an extremely interesting and exciting piece of research aimed at advancing the state-of-the-art in large wind metrology…. and provides a high degree of sophistication and flexibility over traditional methods and helps to provide more intelligent monitoring and control systems designed to enhance overall turbine efficiency and performance.”

Garrad Hassan introduction to lidar by ZephIR / QinetiQ Remote Sensing Positioning Statement – Issue A First statement globally assessing and evaluating the acceptance of remote sensing. ZephIR enters Stage 1, completes Milestone 1, enters Stage 2: “Provided suitable off-site and/or onsite validation steps as defined above are carried out, and the results of these validations are positive, then GH consider that data recorded using the ZephIR device may be used in a quantitative sense for the formal assessment of the wind speed and energy production of a potential wind farm site.” Advice stated to provide tall mast verification - ZephIR launch UK Remote Sensing Test Site.

July 2007

August 2010

Remote Sensing Positioning Statement – Issue B ZephIR demonstrates Stage 2 progress with body of evidence being developed for Stage 3. ZephIR ‘Best practice verification methodology’ endorsed by Garrad Hassan. Remote Sensing Positioning Statement – Issue C ZephIR enters Stage 3: “For relatively simple terrain sites… data from the ZephIR device may be used in a quantitative sense with reasonable error bars for the purpose of the assessment of the wind regime at a potential wind farm site.”

October 2012

Remote Sensing Positioning Statement – Revised document ZephIR achieves Stage 3 acceptance: “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. “

October 2014

Offshore lidar verification ZephIR achieves endorsement. “similar uncertainty results would be obtained from an energy prediction based on data from a WINDCUBE or ZephIR lidar mounted on a stationary platform energy prediction based on data from a as the uncertainty results from an conventional offshore mast.“

2015 - 2016

Turbine-mounted lidar verification Test parameters defined ready for installation and demonstration of performance verification. Floating lidar verification Operating within the CATUPALT Offshore Wind Accelerator roadmap which will result in: “Floating lidar device accuracy can be considered to approximate that of conventional fixed onsite met masts, albeit with a marginal level of residual uncertainty relating to site-specific deployment conditions.” All environment performance Inclusion of complex terrain building upon FGW TR6 standards, linked to the iEA and DNV GL involvement

COMMERCIAL OFFERING – PURCHASE PRICE BUY LIDAR – THROUGH LIFE COST

At £75,000 for the purchase of a ZephIR 300 with 3 year ZephIR Care package, over a 3 year period, ZephIR 300 is cost comparable to an IEC compliant, well instrumented 80m met mast (and 40% cheaper than the nearest competing lidar)

14

•

No annual servicing or calibration

•

Un-paralleled service and support level

•

Offers the ‘best value’ methodology for wind data collection

COMMERCIAL OFFERING - SUPPORT LAUNCH OF ‘ZEPHIR CARE’ The ZephIR Care package is provided with all new ZephIR 300’s and includes, as standard: A ZephIR 300, with IEC compliant met mast validation, dedicated technical support engineer available via telephone and to perform remote diagnostics, optional daily monitoring, choice of data delivery (email, FTP, web interface, real-time) and a replacement ‘courtesy’ ZephIR in any event where an infield issue cannot be quickly resolved remotely.

We believe this to be a step change in aftersales service, unmatched by any wind measurement equipment provider in the market.

We are able to offer this because we have the operational evidence to show that the simple, robust nature of the continuous wave lidar technology found in ZephIR can operate continuously for a 3 year period.

IN PRACTICE Gaelectric’s 42 MW Dunbeg Wind Farm located in County Derry~Londonderry, Northern Ireland, 14 Enercon E82 3.0MW wind turbines, at a hub height of 84 m. Gaelectric deployed a ZephIR 300 wind lidar to verify the wind shear at the site Natural Power and DNV GL (formerly GL Garrad Hassan) commissioned to undertake an independent energy production assessment. Full operational availability of the ZephIR 300, and an extremely high data recovery rate at all measurements heights was achieved. Co-efficient of determination (R2) equal to or greater than 0.99 and a regression slope within the industry accepted standard of ±2% of unity being observed at all heights. The deployment of ZephIR 300 saw the P90/P50 ratio increase by 2% Gaelectric’s ZephIR 300 has since been deployed on the 12 MW Monnaboy Wind Farm in County Derry~Londonderry and is currently on its next deployment on the 16.1 MW Smulgedon Wind Farm, which is located in County Derry~Londonderry, all for similar purposes.

IN PRACTICE In 2009, REG purchased three ZephIRs to operate across the company’s entire portfolio of projects. The methodology is to install the short mast as the long term reference, collecting at least 12 months data covering seasonal variation. The ZephIR is installed for 6 months next to the mast - 6 months is an adequate length of time to measure a significant range of wind speeds across all sectors. Full and detailed energy yield calculations and uncertainty analyses provide the necessary input to Energy Yield Analysis reports. Throughout the campaign, very strong correlations between the ZephIR and mast at the 16m height were observed with just 0.9% variation in all sectors overall. No other considerations to structures nearby were needed. Acting as Banks Engineer for this site, GL Garrad Hassan provided detailed energy yield calculations and uncertainty analysis to provide the necessary Energy Yield Analysis (P50 & P90) report; using the short mast data and the ZephIR data as verification of the wind shear. Wind resource assessment consultancy Prevailing also provided a report identifying the P50 and P90. A correlation between the devices was used to combine the longer period of mast data with the hub height ZephIR measurements. In early Oct 2012, project financing was granted to REG by the Co-op for GBP£10m at a rate of 5.7% The data collected was also used to inform site condition reports for the turbine contract with Vestas.
