FTI Consulting: PTC Time Crunch Could Jeopardize Repowering Opportunities


As the U.S. wind energy market races to complete projects before the production tax credit (PTC) cliff, opportunities for repowering existing assets must be accompanied by thorough and comprehensive due diligence in order to avoid damaging pitfalls, according to Chris LeWand, co-leader of the global clean energy practice at FTI Consulting.

A growing volume of U.S. assets are approaching the middle or end of their useful lives. Repowering these aging wind assets – either by replacing older units with new, higher-capacity turbines or by retrofitting more efficient components – could deliver significant improvements to project lifespan, reliability and returns, says LeWand.

With one eye on the 10-year lifespan of PTCs for existing projects, stakeholders in the U.S. wind market have shown a justifiable appetite to partially – or fully – repower projects prior to the “begin construction” and “placed in service” deadlines.

This can create substantial time pressure, and asset developers, owners and investors must not drop the ball when it comes to managing repowering risks as they rush to complete projects, LeWand advises. Repowering can be highly complex from a development and technical perspective, and robust due diligence must be undertaken – both to ensure PTC qualification and to avoid unforeseen flaws that can derail a project.

Specifically, according to LeWand, stakeholders should focus on the following considerations for repowering projects:

  • As with new projects, repowering initiatives must comply with “begin construction” and “placed in service” requirements to qualify for the PTC;
  • Partial repowering initiatives may prove complex to finance and will be highly vetted, and distinctions between old and new equipment must be considered from a PTC eligibility, technical and operating perspective;
  • Any design modifications may involve additional permitting, with potential ramifications on the project timeline; and
  • Conflicts may arise with existing contracts, and it may be necessary to agree on new or extended contracts.

“Substantial opportunities exist for investors and asset owners looking at repowering aging wind farms before their respective ‘begin construction’ and ‘placed in service’ deadlines,” explains LeWand. “But it’s essential that, in the rush to meet these, stakeholders in repowering projects don’t hit unforeseen stumbling blocks that can have a significant impact on project timelines, development and financing.

“While repowering opportunities are currently attractive, repowering will still be viable in certain cases post-PTC,” he continues. “Alternative solutions that merit serious consideration include lifetime extension and optimization.”

LeWand will be speaking on a panel entitled “Strategies for Aging Wind Assets” at the Infocast Wind Power Finance and Investment Summit, taking place Feb. 5-7 in San Diego.
