The Rewa solar project is a 750MW photovoltaic solar park located in the Rewa district of Madhya Pradesh.

Although partial operations of the solar project were started in July 2018, the 750MW solar park was officially inaugurated by the Prime Minister Narendra Modi on July 10, 2020.

The prime minister said that not only Madhya Pradesh is getting electricity from the 750 MW Rewa Solar Project but it is a matter of joy that the project is providing 24 percent of its power to Delhi Metro also.

It’s a public-private partnership (PPP) project and considered one of the largest single-site solar power plants in India.

The project developer - RUMSL is a Joint Venture of Madhya Pradesh Urja Vikas Nigam and Solar Energy Corporation of India. The Rewa solar park development partners include Mahindra Renewables, a wholly-owned subsidiary of Mahindra Susten, ACME Jaipur Solar Power, a subsidiary of Acme Solar, and Arinsun Clean Energy (now Spring Energy) were selected by RUMSL as the successful bidders to develop each of the three generating blocks on a BOOT basis within the Rewa solar park in the first half of 2017.

It has three blocks of solar installations of 250MW capacity each. Each such unit in the solar park is developed and operated by a separate private company on a build-own-operate-transfer (BOOT) basis for a period of 25 years. Each 250MW block within the Rewa solar park features photovoltaic solar panels mounted on fixed frame aluminum structures.

The inverters near the solar installations are connected to 2MVA 440V/33kV ONAN transformers. The pooling station within the solar park comprises three 33/220 kV 100MVA step-up transformers.

A 220/400kv grid sub-station located on an 18ha-plot within the project premises receives the electricity output of the solar park and transmits the same to the National Grid through a 32km long 400kV transmission line connecting the Vindhyachal-Jabalpur transmission line.

The total investment on the project is estimated to be approximately $530 million. The World Bank also approved $100m under this project to cover the financing of the shared infrastructure, including access roads, water supply, telecommunications, pooling stations inside the solar parks as well as the transmission lines connecting to the external substation for the Rewa as well as the Mandsaur solar parks.

The solar park is spread over an area of 1,500 hectares in the Gurh Tehsil in the Rewa District of Madhya Pradesh. Each generating unit within the solar park occupies approximately 500 hectares.

The three 250MW solar blocks were awarded at tariffs as low as Rs 2.9 per unit which is considered to be the lowest tariff ever awarded for a solar project in India.

The project will deliver renewable electricity at one of the lowest tariff rates in the country and offset approximately 1.5 million tonnes of carbon emissions annually.

The majority of the equipment used in the solar park was provided by Chinese suppliers.
