The 168.5 megawatt figure might be using the old TE prices. As the underlying Proxy shows, TE expects to recognize $44 million in revenue from SolarCity during 2016.
Tesla Proxy said:In December 2015, we entered into a master supply agreement with SolarCity that governs SolarCity’s purchase of second-generation energy storage systems from us pursuant to purchase orders issued during 2015, and creates a framework under which SolarCity may purchase further Tesla energy storage products in 2016. We recognized approximately $4.9 million in revenue from SolarCity during fiscal year 2015 for sales of energy storage products governed by this master supply agreement, and anticipate recognizing approximately $44.0 million in such revenues during fiscal year 2016.
Also in December 2015, pursuant to a competitively bid process, we selected and entered into three power purchase agreements with SolarCity, pursuant to which SolarCity will design, build, own and operate solar panel systems at three of our facilities in California, and Tesla will purchase electricity generated by those systems for use at those facilities, at costs that are expected to be lower than would be available from the applicable public utility company. Two of such agreements have terms of ten years, and one such agreement has a term of 20 years, in each case corresponding to the lease term of each facility, and we estimate that the total amounts payable by Tesla over their respective terms will be approximately $2.0 million, $2.4 million and $8.4 million, respectively.
