SoftBank's arm SB Energy is close to signing a pact to invest in a 500MW solar power plant being developed by the Essel Group in Rajasthan. Essel Group is in the early stages of developing a solar power park in Rajasthan with a total capacity of 750 MW. This investment will help SoftBank fast forward its plan as it will have all the necessary infrastructure. This will reduce the time to build a plant from 12-15 months to less than six months. SoftBank is bullish on the Indian solar energy space and has plans to invest $1 trillion in the sector. It has a presence in India through SB Energy, its joint venture with Bharti Enterprises and Taiwan′s Foxconn Technologies. In October, SoftBank CEO Masayoshi Son offered to supply free electricity to India once the 25-year power purchase agreements of SB Energy came to an end. The company has urged the government in the past to offer bulk tenders for solar power plants so that it can expedite its plan to invest $1 trillion in India. The Subhash Chandra-led Essel Group has plans to expand its solar power portfolio by developing its own parks.
