SB Energy has bought 1.7 GW of solar projects under development in California and Texas from fast-growing developer Intersect Power.

Japanese conglomerate SoftBank is known for many things, including the renewable energy ambitions of its colorful billionaire CEO, Masayoshi Son. But it is coming to be known as a big owner of U.S. solar as well.

Yesterday subsidiary SB Energy announced that it will acquire a portfolio of five solar projects under development by Intersect Power, an equally interesting if smaller player. Under the leadership of power trading guru and U.C. Berkeley Business Professor Sheldon Kimber, in three years Intersect Power has developed and engineered 2 GW of solar projects from inception to COD – not including the five projects it just sold to SoftBank.
