Mahindra Susten aims to ‘Think Big’ with Rewa Solar Park

Implementation of a 250 MW unit at Rewa Solar Park in Madhya Pradesh shows Mahindra Susten’sability to think big

Mahindra Susten, formerly Mahindra EPC Services Pvt. Ltd., is firmly committed to the renewable energy revolution and has perfected the skill of ‘Thinking Big’. Take, for instance, the 750MW power plant implemented by Rewa Ultra Mega Solar Ltd (RUMSL). The Rewa power plant was inaugurated by Prime Minister Narendra Modi in September 2019 and has the distinction of being Asia’s largest solar power project.In addition to the green power generated, the Rewa solar park project is also expected to reduce carbon emissions equivalent to about 15 lakh tons of carbon dioxide per year.

Spread over 1,500 hectares in Gurh tehsil of Rewa district in Madhya Pradesh, the plant is divided into three units of 250 MW each.

Mahindra Renewables Private Ltd was allotted one 250MW unit through tariff-based competitive bidding conducted by RUMSL. RUMSL, a joint venture between the Madhya Pradesh UrjaVikash Nigam Ltd. and the Solar Energy Corporation of India, is the implementing agency of the Solar Park. Mahindra Susten was one of three companies that won the project in the reverse auction by bidding one of the lowest tariffs.

Numerous challenges had to be overcome before the project could be operationalised. Based on the Rise philosophy of ‘Accepting No Limits’, Mahindra Susten’s engineering team DevCo worked around severalobstacles to complete the project.

The hard strata of the land made digging trenches to lay cables a difficult task. The DevCo team devised a new innovative method for cable laying. The all-terrain cable tray makes use of the vertical posts erected for the module mounting structure. This is the first-ever solar photovoltaic project in which this innovative cable laying method has been utilised.

The team faced several other challenges including power evacuation issues, demonetisation and the introduction of GST, which affected switchyard readiness. Yet, the Mahindra Susten unit was the first to achieve commissioning of the initial part of the project.

The Rewa project is one of Mahindra Susten’s largest ones implemented so far and also the most complex considering the size, land strata, involvement of multiple off-takers and states. The operation and maintenance of the project are handled by Mahindra Teqo, which helped the team secure similar contracts for two other projects in the Rewa solar park. The Mahindra Teqo team manages the entire 750 MW capacity of the park.

Riding on the experience and learning of the Rewa project, the DevCo team have now secured three more projects – two ISTS connected projects of 250 MW each and one state project of 200 MW, taking its total portfolio to 1,650 MWp.

For Mahindra Susten, thinking big has borne fruit.
