The story
Tata Power and BP Solar established Tata BP Solar, a joint venture company, in 1989. The company began commercial operations in 1991 by establishing its first manufacturing unit with a production capacity of 3 MW.
BP Solar was closed on 21 December 2011, when BP announced its departure from the solar energy business. On 30 August 2012, Tata BP Solar India Limited was renamed as Tata Power Solar Systems Limited and became a wholly owned subsidiary of the Tata Group.
In August 2016, Tata Power Solar commissioned a 100 MW solar project at the NP Kunta Ultra Mega Solar Power Project in Anantapur, Andhra Pradesh. This was the largest solar project commissioned using domestically manufactured solar cells and modules at the time.
In 2022, Tata Power Solar raised 4,000 crore from Tata Power and a consortium of investors led by BlackRock, which also includes the Mubadala Investment Company.
