Solar Monitoring Systems Video

Tuesday, March 12th, 2013

This short video by AWS Truepower meteorologists provides a thorough introduction to solar site monitoring:

A thorough understanding of a project site’s solar resource is an essential element to prospecting, detailed project engineering and financing. Publicly available data sources are often used for preliminary site assessment, but imperfect data and models, complex cloud or solar climates, and other factors can combine to create significant uncertainties. With an increase in project size from tens to hundreds of megawatts, a much more rigorous approach is needed to accurately determine a site’s potential.

Actual vs. Predicted Plant Production: The Role of Turbine Performance

Tuesday, February 12th, 2013

This paper, presented by Dr. Michael Brower at the AWEA Wind Resource and Project Energy Assessment Workshop in Pittsburgh, 2012, discusses the role of individual wind turbine performance in the gap identified between actual and predicted plant energy production. Results show that turbine underperformance is a significant contributor to the general problem of plant underperformance. In this research, turbines typically fall 1%-4% short of their advertised power curves even under test conditions that conform to IEC standards and the manufacturer’s specifications.

WEBINAR: The Portfolio Effect for Renewable Energy Projects

Thursday, December 6th, 2012

How the Effects of Uncertainty Are Reduced When Projects Are Assessed as a Portfolio

(Original broadcast Dec. 6, 2012)

When summing the P75-P99 net production values for a portfolio of wind projects directly, it is assumed that the uncertainties are perfectly correlated, which is not usually the case. In this seminar we will discuss the portfolio benefit as it applies to renewable energy projects, introduce our portfolio analysis methodology and the assumptions used, discuss key sensitivity factors, and give real-world examples of ranges of portfolio benefit for different combinations of operational and pre-construction wind and solar projects.

WEBINAR: Operational Analysis of Wind & Solar Projects

Monday, November 12th, 2012

Reduce Uncertainty with Operational Data

(Original broadcast November 8, 2012)

In August 2012, the U.S. surpassed 50,000 MW of installed wind power generation capacity with 8,430 MW under construction, according to AWEA. The U.S. also now has over 5,700 MW of installed solar electric capacity, with 477 MW of new utility scale projects installed in Q2 of 2012 alone, according to SEIA. Once operational, these assets have lower uncertainty compared to the pre-construction energy estimates used in the original financing. This can be valuable for mergers, acquisitions or refinancing of these plants, since the asset is lower risk and can be leveraged accordingly with higher confidence in the P50 and P90 values.

In this webinar, we will share exclusive insights into our methodology and describe the factors that affect the final energy production estimate. In particular, we will highlight comparative analysis showing the relationships between uncertainties in pre-construction methods vs. operational assessment methods.

Mountain Wave Study at a Wind Farm Site in the Eastern Rocky Mountains

Friday, September 14th, 2012

Atmospheric conditions at a complex site in the Rocky Mountains were studied to better understand the wind flow patterns, more specifically, why the anemometers were measuring higher wind speeds on the lee side of the mountain rather than at the top. Numerical simulations with the Advanced Regional Prediction System (ARPS) showed that it was due to mountain waves. View the slide deck.

Are Advanced Wind Flow Models More Accurate

Thursday, August 30th, 2012

This presentation describes the results of a comparison of four wind flow models, including WASP, a CFD model, and two advanced models, and asks the question: Do more sophisticated models make a difference? The answer is yes.

Download the presentation.

More detail on this topic can be found in the paper titled, Wind Flow Modeling Performance.

WEBINAR: Wind & Solar Project Due Diligence

Monday, June 25th, 2012

An in-depth look at risks that can make or break a project.

(Original broadcast June 21, 2012)

Due diligence services support developers and investors during project financing, mergers and acquisitions, finance restructuring, and other transactions occurring in the renewable energy industry. These services provide lenders with a structured approach to assess project risk by ensuring the project is well planned, well executed, and capable of generating reasonable and timely returns.

In this webinar, AWS Truepower discusses the dangers of not doing a thorough due diligence, the typical scope of work for a bankable due diligence report, and some typical fatal flaws that can make or break a project’s chance of being financed.
