Tata Power Solar has secured a solar EPC order from Indian state-owned utility SJVN Ltd.

It is said to be the largest single solar EPC order in India, worth around INR 55 billion ($715 million).

Developed under the Ministry of New Energy and Renewable Resources (MNRE)'s Central Public Utilities Enterprise Programme (CPSU), the project will use locally-made batteries and modules.

The CPSU aims to build solar projects using domestically produced cells and modules in a "WTO-compliant manner" until 2023. The Indian government will provide funding of up to INR 700,000/MW ($90,000/MW).

Tata Power has been ramping up its investments at both ends of the Indian supply chain

Tata Power Solar said the project is located in the solar hotspot state of Rajasthan, where Tata Power recently launched construction of a 160MW solar power plant, which will be completed in two years and covers an area of more than 5,000 acres.

Praveer Sinha, CEO of Tata Power, said, "We are proud to have won the bid for this large-scale solar project for SJVN. Implementing such a large-scale project reflects our commitment to promoting green and clean energy in India and solidifies our position as a leading solar EPC player status,"

Following the deal with SJVN, the company's order book has exceeded INR 120 billion ($1.5 billion) and the cumulative portfolio of utility renewable energy projects has exceeded 9.3GW.

In April, Tata Power announced that a 300MW solar project in the Indian state of Gujarat had been commissioned. The company says it is the largest single-axis solar tracking system in India. In late April, a consortium led by private equity giant BlackRock Real Assets will invest 40 billion Indian rupees ($525 million) for a 10.53% stake in Tata Power Renewables, which will use the funds to achieve 20GW over the next five years Renewable energy targets.

Tata Power is the backbone of India's solar industry with nearly 2.5GW of grid-connected solar PV projects in India, with operations at both ends of the value chain.

In February, the company said it aimed to build new battery and module capacity in India using India's Capacity Linked Incentive (PLI) and other policy mechanisms. Tata Power did not disclose where it plans to source cells and modules for the project.
