Depreciation expense related to renewable energy facilities was $209.2 million, $135.7 million and $37.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Construction in progress represents costs incurred to complete the construction of the facilities in the Company's current portfolio that were acquired from SunEdison. When renewable energy facilities are sold to the Company after completion by SunEdison, the Company retroactively recasts its historical financial statements to present the construction activity as if it consolidated the facility at inception of the construction (see Note 3. Transactions Between Entities Under Common Control). All construction in progress costs are stated at SunEdison's historical cost. These costs include capitalized interest costs and amortization of deferred financing costs incurred during the asset's construction period, which totaled $1.6 million, $22.7 million and $37.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016, the Company reclassified $548.7 million from renewable energy facilities, net to non-current assets held for sale in the consolidated balance sheet (see Note 4. Assets Held for Sale). There was no amount classified as assets held for sale as of December 31, 2015.
