Power Performance Measurements: Cheaper Faster Better

(Original Broadcast Date: April 21, 2016)

This webinar will provide a vision of power curve testing under the new IEC standard. The use of lidar and other remote sensing technologies is expected to revolutionize power curve testing, eliminating the need for expensive permanent met towers for power curve testing.

Since many turbines have failed to meet expected power performance levels, the new standard offers exciting new options to test turbines at all projects, but at a dramatically lower price. This is expected to offer benefits by reducing the cost of testing, enhancing performance, and shifting the blame away from O&M staff for under-performing projects.

Is Solar Overproduction Costing You?

This webinar reviews the impacts of solar resource data on financing and revenues for PV plants.
(Original broadcast date: November 18, 2014)

Investors and debt participants require accurate resource and energy production assessments in order to establish project revenues with a level confidence and to size debt appropriately. There are times when plant performance exceeds the pre-construction energy estimate. What are the financial implications? In this webinar we discuss how reliance on poor quality resource data and energy simulations impact your bottom line including:

• How over- or underproduction impacts financing with a review of Investment Tax Credits, Power Purchase Agreements, and debt sizing.
• Investigation of why solar plants are over- or underproducing.
• Why resource data selection and typical meteorological year (TMY) development is critical to maximize return on investment for solar power plants. View Video


Maximize Plant Performance: Data Mining to Implement a Better O&M Strategy

(Original Broadcast Date: July 10, 2014)
Wind plants generate massive amounts of data which, if utilized properly, can provide significant insight for operational improvements resulting in more proactive plant management and better return on investment. Trying to understand all of the data a wind farm can generate can be time consuming for plant management.

In this webinar AWS Truepower President, Dr. Bruce Bailey, and Chief Engineer, Daniel Bernadett, discuss how performance issues can be addressed through diagnostic data mining. They share a case study demonstrating how the implementation of diagnostic techniques led to increased overall performance at a wind facility by modifying the operations and maintenance strategy.

Complex Wind - Tehachapi Pass

Managing Wind Resource Risk at Complex Sites: An Integrated Approach

(Original Broadcast Date: February 20, 2014)
How meteorological expertise, state-of-the-art atmospheric models and advanced measurement methods can increase project value and reduce financial risk.​

All wind project investments depend greatly on the uncertainty or risk in a project's wind resource estimates. This is especially true of large wind projects at complex sites with steep terrain, varying thermal stability, mesoscale circulations and other challenging meteorological aspects. Such conditions are often misrepresented or missed in conventional models and measurement techniques.

In this webinar by AWS Truepower, wind resource experts Dr. Michael Brower, Dr. Philippe Beaucage, and Matthew Filippelli will discuss case studies of actual wind projects in complex terrain and wind regimes, showing how an integrated approach combining meteorological expertise, advanced wind flow models, and remote sensing (sodar and lidar) can increase a project's value and reduce risk.

Understanding the Financial Impact of Uncertainty in Wind Projects

How risk translates to dollars in wind projects.
(Original Broadcast Date: November 7, 2013)

One of the biggest risks in wind development is the uncertainty of the wind resource. In this webinar by AWS Truepower, we will demystify how this resource uncertainty impacts energy production estimation, investment and financing. Presented by AWS Truepower CEO Bruce Bailey, and Director of Investor Services, Josh Kunkel, the following topics will be discussed:

• The steps Involved in predicting wind plant output
• Sources of losses and uncertainty
• Probabilities of energy exceedence and how to interpret them
• The impact of energy uncertainty on capital structure and debt capacity
• Implications of energy values on future cash flows View Video


Offshore Wind Load Coincidence Value in the Eastern US

Originally Broadcast September 19, 2013

This presentation by Bruce Bailey, CEO of AWS Truepower, discusses the load coincidence attributes of offshore wind development along the eastern seaboard of the United States. These attributes provide significant economic value to summer peaking load regions, which dominate electricity markets in the eastern US. The talk explains the meteorological factors that provide this value and illustrate how the capacity value of offshore wind is 3 to 4 times that of land-based wind.

The Portfolio Effect for Renewable Energy Projects: How the Effects of Uncertainty are Reduced When Projects are Assessed as a Portfolio

In this seminar we discuss the portfolio benefit as it applies to renewable energy projects, introduce our portfolio analysis methodology and the assumptions used.

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.

Operational Analysis of Wind & Solar Projects: Reduce Uncertainty with Operational Data

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. View Video


Wind and Solar Project Due Diligence: An In-depth Look at Risks That Can Make or Break a Project

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. View Video

Reducing Uncertainty in Solar Energy Estimates

Uncertainty Matters… Solar project risks can be uncovered at various points in project development. A number of factors impact energy potential and its uncertainty — the quality of a site’s solar resource assessment is one of the most significant, with the potential to derail a project.

Based on research conducted by AWS Truepower, this webinar will demonstrate the value of on-site meteorological measurements in determining your solar project’s long-term energy projections. Our case study examines 11 sites, comparing results using on-site data versus satellite modeled data alone allowing us to quantify the impact on uncertainty (P50 – P99 values) for energy estimates and the financial implications for large and utility-scale solar projects.
