The Internal Revenue Service (“IRS”) provided taxpayers a safe harbor opportunity to retain access to the pre-2020 30% tax credit amount through specific rules released in Notice 2018-59. The Company has sought to avail itself of the safe harbor in order to retain the 30% Commercial ITC that was available in 2019 with respect to approximately 500 MW of projects by incurring certain costs and taking title to equipment in 2019. As of December 31, 2019, there was approximately $132.6 million related to the safe harbor program within raw materials.
