NUO MetMast: your ally in converting wind data into bankable information
Wind measurement campaigns are the backbone of wind farm development, yet they are notoriously complex due to the intersection of harsh environments, logistical hurdles, and high precision requirements.
Data acquisition in these campaigns generally relies on either physical meteorological masts (Met Masts) or Remote Sensing Devices like LiDAR or SoDAR.
The typical challenges
Connectivity and Power Supply
- Dead zones: many campaigns occur in areas where infrastructure is non-existent.
- Autonomous power: systems often rely on solar panels and battery banks. During winter months with low solar radiation, the data acquisition system may shut down, leading to critical data gaps that can invalidate a campaign for financing purposes.
- Data backhaul: If cellular coverage is poor, retrieving data in real-time is impossible. Relying on manual SD card collection increases the risk that a sensor failure remains undetected for weeks.
Data Integrity and Filtering
- Cleaning "Non-Representative" Data: analysts must filter out data points affected by bird interference, nearby construction, or temporary obstacles.
- Data Recovery Rates: most financial institutions require a 90% or higher data recovery rate. Managing the "missingness" of data,and deciding how to "gap-fill" using nearby long-term reference stations, is one of the most contentious aspects of wind resource assessment.
NUO is the answer
The introduction of the NUO’s digital ecosystem addresses the primary human-errors and latency gaps that plague traditional wind measurement campaigns. By shifting from manual oversight to an automated and intelligent layer, it mitigates several of the most costly risks in wind resource assessment.
How NUO mitigates key risks
In traditional setups, a logger might stop transmitting due to a power failure or a SIM card error, but the technician may not notice for days or weeks.
- The challenge: data recovery rates falling below the 90% bankability threshold because of undetected downtime.
- With NUO: by automatically acquiring data and providing instant notifications of communication issues, the system ensures that maintenance teams can react the moment a heartbeat is lost. This maximizes the continuity of the dataset, which is critical for financial closing.
