The Spillover Effect: The ITC Extension’s Impact on U.S. Utility Solar Projects in 2016

by Colin Smith

This new brief discusses the effects of the December 2015 extension of the U.S. federal Investment Tax Credit on current U.S. utility solar projects. Prior to the extension, developers built up a massive 21+ GWdc pipeline of utility PV projects in the U.S., all of which had to be completed by the end of 2016. Now that Congress has extended the ITC through 2022, an opportunity has opened up for projects to spill over or be pushed out into 2017 without the risk of losing the 30% tax credit that is critical to ensuring that many of the projects will be profitable. GTM Research offers insights into what types of projects will spill over and how much we can expect to come online in 2017.
