Wind Repower & Retrofit Due Diligence Summit
February 11-12, 2019 | La Jolla, CA

Access PDF Brochure
 

Overview

The National Renewable Energy Laboratory has estimated that U.S. wind repowering investments could reach $25 billion a year by 2030.   Wind repowering – replacing older turbines or other components on a wind farm to improve power capacity and generation – is increasingly becoming an attractive option for developers, owners and investors to profit off existing wind project assets.  Federal production tax credit incentives, technical advancements in wind turbine technology, and opportunities for increased performance and revenues are all driving the repower movement.  Moreover, North America’s aging wind fleet is causing a surge in operations and maintenance spending from the wind industry, with project owners spending up to $4 billion annually.  Repowering wind farms is a viable solution to manage these increasing O&M costs, all the while improving capacity and revenues.   All these incentives are prompting the wind industry to evaluate a full spectrum of repower development – from a range of ‘partial’ repowers that involve simple to more complex technical updates – to full repowers, where entire wind farms are decommissioned and replaced with new turbines in the same project area, or relocated to a more economical area.

This emerging repower movement is an attractive opportunity for the wind industry, with experts estimating that repowered turbines can increase fleet output by 25% and add 20 years to turbine life (General Electric).  However, although repower projects holds big potential, there are major challenges involved that must be evaluated when considering or undergoing the repower process.  Each wind farm is unique and will require a critical due diligence review of financial, technical, and legal considerations to determine if repowering is: 1) a profitable option; and 2) what type of upgrades are necessary to optimize wind generation resources and revenues.

This program is designed to provide expert insight on the repower development market, providing holistic coverage of the financial, technical, and legal due diligence items involved in repowering wind farms, and insight on evaluating what constitutes as a bankable repower project.  This instructional symposium will be relevant to both industry veterans and those new to the business.

  • Below-ground foundation inspection
  • Cracked versus uncracked properties
  • Skewed wind load test
  • Site specific design loads
  • Exposed foundation inspection findings
