SolarCity(Nevada) and the Gigafactory =Nevada?

Nevada-The Governor’s Office of Economic Development doled out $1.2 million in funding and/or tax incentives from Nevada’s Catalyst Fund to get Elon Musk's California-based SolarCity to locate operations in Las Vegas.

From The Motley Fool:
There is one joint-venture partner that we can almost certainly count on: SolarCity. Musk has already said that the Gigafactory will be both solar and wind powered, thereby making the plant both green and self-sustainable to some extent, therefore making SolarCity an obvious fit for the undertaking.

Not to mention, Tesla and SolarCity currently work together on other ventures. SolarCity, for example, provides the solar panels used to power Tesla's Supercharger stations throughout the world. Meanwhile, similar to Apple and Tesla, SolarCity relies on lithium-ion batteries to power its new solar-energy-storage systems. There's also the family factor. You see, Musk is the cousin of SolarCity's CEO, Lyndon Rive, and a majority shareholder in the company.
