Natural Power completes environmental impact assessment for Tellenes Wind Farm.

Natural Power has delivered an independent energy yield assessment (EYA) for financing purposes on behalf of SunEdison Norway Holdings B.V for Tellenes Wind Farm. The energy generated by the project has been purchased by Google for a 12-year period to supply its European data centres.

The 160 MW project is located near Sogndalis, Norway, and comprises 50 Siemens SWT 3.2-113 turbines.

Lauren Wheatley, Natural Powers Director of Technical, said: "Energy yield estimates are the cornerstone of wind power financial models and the accuracy of these is therefore imperative. We are delighted to have completed this recent EYA on behalf of SunEdison as we continue to develop new innovations and learn from our assessment and operational experience to confirm the accuracy of our work."

Earlier this year, Natural Power released the results of its latest validation study - an evaluation of pre-construction wind energy yield predictions by comparison to operational production - demonstrating analysis 1.1% median bias ensuring an accurate assessment of long-term wind farm generation

A finance grade (often referred to as "bankable") independent energy yield assessment can be relied upon by lenders or other parties with a financial interest in a wind project. It is a robust and defendable energy yield analysis and uncertainty study. It aims to predict the long-term wind resource and average energy production of a wind farm over its lifetime and quantify the associated uncertainty inherent in these predictions. An independent energy yield assessment is an essential element in securing project funding and aims to provide owners and investors with the confidence to make well-informed financial decisions.

Over its 20-year history, Natural Power has provided wind analysis services on over 60 GW of wind and technical due diligence on over 40 GW of wind and solar projects. It currently operates over 150 projects in four countries (UK, US, France, and Ireland). As thought leaders and pioneers in several areas, including the development of wind-specific computational tools, furthering industry understanding of remote sensing in wind assessments, and application of computational fluid dynamics to complex wind projects, Natural Power has pioneered new technologies, methodologies and best-practices to tackle the most complex and challenging issues. Throughout this history, the business has conducted multiple assessments to evaluate and improve its energy yield methodology.
