ArcVera Renewables' Study Proves Its Wind Energy Resource Assessments Reach 100% Mean Accuracy

ArcVera Renewables, a leading provider of consulting and technical services for wind and solar projects with more than 30 years of experience, has developed and published earlier this year an ambitious benchmark report that aimed to deliver a thorough analysis of the performance of its wind energy resource assessment (WERA) practice across a broad range of operating wind projects.

Based on a dataset composed of 31 projects it worked on in the United States, combining 3.5GW of installed capacity and 212 years of operation, the report provides a detailed comparison between the pre-construction assessments using ArcVera's advanced WERA practices and the actual post-construction energy production data.

The results of the study show that ArcVera's wind assessment techniques are accurate to within about 1% on average of reported project P50 energy production, which becomes near zero mean bias after accounting for grid curtailment.  In addition, the benchmark study indicated that ArcVera's wind assessments have lower individual project performance variation than in the past. With an average project performance bias close to zero, ArcVera's advanced methodology yields an average project performance of 98.8% for the 31 projects.  Given that estimates of grid curtailment losses, typically at 1 to 1.5%, are not corrected for in most benchmark assessments, ArcVera's overall project performance is effectively 100% in terms of accuracy.

Even more impressively, the results show that the risk of building a wind farm that significantly over- or under-performs is limited by applying ArcVera's techniques, with an industry-leading 4.7% standard deviation of project performance.  No firm is currently assessing wind farms with the accuracy achieved by ArcVera.

"For over thirty years, ArcVera Renewables has provided finance-grade consulting and technical services for wind and solar energy clients worldwide, including the very first bankable WERA delivered in 1989 in California. Our track record is second to none, and we wanted to make public the data that supports that claim. We have consistently delivered accurate and bankable insights backed by advanced technical expertise and decades of global experience. That kind of highly specialized services is what you need to make sure that confident project development decisions are taken, maximum technically-driven advantage is secured, and performance risk is minimized," commented John Bosche, President and Principal Engineer at ArcVera Renewables.

ArcVera Renewables is a recognised pioneer of WERA practices, which evaluated more than 60% of the installed wind capacity in the US.  The Colorado-based company worked on the very first wind farm in eighteen US states, as well as Puerto-Rico, Guatemala, Nicaragua, and, shortly, El Salvador.

Mita-Teknik launches next-generation blade pitch technology

Mita-Teknik, a global provider of wind turbine control and pitch technology, announced today the launch of its new generation of blade pitch system for onshore and offshore wind turbines. The new Mita Pitch System has been designed to effectively minimize O&M costs, reduce downtime and improve productivity.

The Mita Pitch System is a flexible pitch solution for turbines up to 12 MW, which boasts a design life of 30 years. It has been designed to maximize the availability and performance of wind turbines, while applying minimum loads to the structure. High availability is ensured by fast commissioning, a Built-In-Self-Test scheme for on-the-fly evaluation, simple maintenance procedures, and digitalization. Digitalization is an asset created by integrated CMS and intelligent algorithms collecting data of high accuracy and veracity, providing the valuable data insights needed to support operation and maintenance planning.

The system features a modular pitch design with integrated drives, based on various standardized sizes of Hub Units, Blade Units, brushless PM Servo Motors, Asynchronous Servo Motors as well as energy storage based on either ultracapacitors or long life VRLA batteries. It is designed as an open system allowing OEMs to integrate their own software in the hub controller.

The Mita Pitch System is the result of thousands of engineering hours and it underwent an extensive quality test procedure, explains Thomas Andersen, CTO at Mita-Teknik: "The high quality of this product comes from a mix of excellent engineering, top-shelf components and thorough testing procedures. Every single component has been selected and specifically tested to maximize performance and reliability", he said.

This robust system has been designed to sustain the harsh environment of the rotating wind turbine hubs and can deal with operating temperatures ranging from -30°C to +60°C, as well as continuous vibrations and forces. By removing the traditional "cabinet in cabinet" approach, Mita-Teknik was able to maximize the system reliability, avoiding high ambient temperatures inside the cabinet.  The Mita Pitch System offers innovative features such as ruggedized IP65 seawater resistant aluminum housings, smart energy management extending component service life, as well as touchless blade angle monitoring.

"Our new pitch system generation capitalizes on decades of experience and best practice in pitch design. It is designed to prevent expensive downtime and costly maintenance. Only a small number of wear parts are used; this is a crucial factor in securing the long design life of the system, as this reduces failures at component level whilst lowering the overall maintenance costs. This is how we provide the highest investment value to our customers", said Torben Jensen, Leading Chief Engineer at Mita-Teknik.
