Exhibit 99.6

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

In order to present the financial effect of the acquisitions of the Panhandle 1 and Panhandle 2 projects, which are scheduled to close at various times prior to the end of 2014, the following tables present unaudited pro forma consolidated balance sheet data as of March 31, 2014, pro forma consolidated statement of operations and other financial and operating data for the three months ended March 31, 2014 and the year ended December 31, 2013, after giving pro forma effect to (i) the transfer of assets and assumption of liabilities relative to the Panhandle 1 and Panhandle 2 projects at carried book value assuming a combination of entities under common control and before the capital contributions from tax equity investors expected at closing (ii) the estimated cash consideration payable by us for the acquisitions of the Panhandle 1 and Panhandle 2 projects and (iii) the estimated net proceeds of our primary public offering of shares of Class A common stock. The pro forma consolidated balance sheet, consolidated statement of operations and other financial and operating data presented are not necessarily indicative of what our actual results of operations would have been as of the date and for the periods indicated, nor does it purport to represent our future results of operations.

The pro forma consolidated financial data presented reflect events directly attributable to the acquisitions and certain assumptions we believe are reasonable. The acquisitions will be completed at various times prior to the end of 2014.

The unaudited pro forma consolidated balance sheet assumes that the acquisitions occurred on March 31, 2014. The unaudited pro forma consolidated statement of operations for the three months ended March 31, 2014 and the year ended December 31, 2013 assume that the acquisitions occurred on January 1, 2013.

Our historical consolidated financial statements, from which the unaudited pro forma consolidated financial data have been derived, are presented in U.S. dollars and have been prepared in accordance with United States Generally Accepted Accounting Principles, which differ in certain material respects from International Financial Reporting Standards.

You should read the following tables in conjunction with “Structure and Formation of Our Company,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the historical consolidated financial statements and the notes thereto included in our periodic report on Form 10Q for the three months ended March 31, 2014 and our Annual Report on Form 10K for the year ended December 31, 2013 filed with the Security and Exchange Commission.
