Accredited Power Performance Testing Services

Experience matters because it results in quality and efficiency.

Very small variations in turbine performance meaningfully impact financial returns; accurate results are critical to having the best understanding of project performance. Proven methodology guided by a technically experienced team translates to high-quality outcomes and efficiencies, such as lowering the need for additional verification testing to settle results.

The ArcVera power performance testing (PPT) team is committed to having experienced professionals on-site to install hardware, troubleshoot, and ensure high-quality results and customer service.

30 years of experience in Power Performance Testing

Running power performance tests is a highly complex task that requires a great amount of experience. Over the years, we have completed or monitored wind energy project PPTs for leading industry players such as RES, Iberdrola, RWE Renewables, BHE Renewables, Scout Clean Energy, BlackRock, Energy Northwest, NPPD, Leeward Renewable Energy, BayWay r.e., NextEra, Northland Power, Ridgeline Energy, and the US Department of Energy.

ArcVera Renewables has received A2LA accreditation in accordance with ISO 17025 laboratory standards and power performance testing according to IEC 61400-12-1.

We are preferred Vendor for GE Renewable Energy and Siemens Gamesa Renewable Energy and Approved by Vestas, Nordex, Goldwind, and other manufacturers.

Because of our Senior-level expertise long-engaged in PPT services, we have been directly involved in maintaining the IEC 61400-12-1 standard and translating the standard to inform ArcVera PPT services from project start to finish.

ArcVera is also an active member of the IEC standards committee currently participating in the development of the IEC61400-50-3 Nacelle Mounted LiDAR Wind Measurement test standard that can be used for power performance testing without the installation of a met mast for offshore and onshore applications.

Offshore power performance testing: New and advanced offshore wind technology requires thorough testing

Offshore wind is the newest frontier for wind turbine technology evolution and is still evolving. The blades are getting longer, and the towers are getting taller, but how will investors ensure they are getting the expected power curve? Our Power performance testing (PPT) service will ensure that the offshore wind projects will perform as forecasted.

We complete IEC 61400-12-1-compliant power performance tests and monitor such tests, complete proxy tests throughout the project lifetime, calculate nacelle transfer function and perform remote sensing-based power performance tests.

To account for the expense and complexities of installing met towers in the ocean, offshore wind projects benefit from the IEC 61400-50-3 standard for nacelle-mounted lidar for measurements. ArcVera’s membership in the IEC committee to develop those standards puts us at the forefront of PPT for offshore wind.

ArcVera Renewables has received accreditation by the International Standard ISO/IEC 17025:2017 from the American Association for Laboratory Accreditation (A2LA) for ArcVera’s wind turbine power performance testing services. This accreditation certifies the quality of ArcVera’s wind turbine PPT processes and the competence of its quality management system.

Our power performance testing service includes:

  • Test planning
  • Site assessment
  • Site calibration
  • Met tower and sensor installation
  • Warranty power performance testing to IEC 61400-12-1: 2005 or 2017
  • Monitoring and quality assurance of third-party tests
  • Nacelle transfer function and proxy power performance tests

Heart of Texas Wind Project

  • Capacity: 180 MW
  • Turbine type: GE 2.8-127, GE 2.72-116, GE 2.52-127 *
  • Location: McCulloch County, Texas, USA
  • Online date: COD April 28th, 2020

As a key technical advisor to Scout Clean Energy, ArcVera has provided leading technical support for the Heart of Texas and other wind energy development projects. With the construction of Heart of Texas completed in June 2020, Scout needed to complete a power performance test to verify the wind turbine performance matched the contractual requirements. As the technical advisor for the project through acquisition, Scout requested ArcVera provide its power performance testing (PPT) services. The PPT services began in October 2020, and the project was completed in March 2021. Three separate tests were performed, one for each version of the GE 2-MW wind turbine installed.

* 4 WTGs are the GE 2.8-127 model, and all three of the tested turbines were GE2.8-127

Sweetwater I & II Wind Farms

  • Capacity: 129 MW
  • Turbine type: GE-1.5sl (70.5 m), GE-1.5sle (77 m)
  • Location: Sweetwater, Texas, USA
  • Online date: December 2003, March 2005

ArcVera Renewables’ work on the Sweetwater I & II Wind Farms spans the entire life cycle of both projects: initial site prospecting, site visits, defining the wind measurement campaign, development stage wind reports, turbine layout design and micrositing, financing wind energy resource assessment reports, power performance testing, operational assessments throughout project lifetime, independent engineering, and repowering. The Sweetwater development area continues to be a very notable part of wind energy development nationwide.
