What is the Rewa Solar Park? An Overview
The Rewa Solar Park is a 750-megawatt (MW) photovoltaic solar power plant. It is spread over a vast area of 1,590 hectares (nearly 4,000 acres). The park is located in the Gurh tehsil of Rewa district in Madhya Pradesh, India. At the time of its commissioning, it was one of the largest single-site solar power plants in India and the world. Its sheer size is a testament to the scale of India’s renewable energy goals.
The project is officially known as the Rewa Ultra Mega Solar Limited (RUMSL) project. It is not owned by a single entity. Instead, it is divided into three units of 250 MW each. These units were developed by three different companies through a transparent and competitive bidding process. This model ensured efficiency and brought in expertise from multiple leading players in the solar industry.
The Joint Venture: Rewa Ultra Mega Solar Limited (RUMSL)
The project’s success is largely due to its unique implementation model. It is managed by Rewa Ultra Mega Solar Limited (RUMSL). RUMSL is a joint venture company.
- Partners: It is a collaboration between the Solar Energy Corporation of India (SECI) and the Madhya Pradesh Urja Vikas Nigam Limited (MPUVN).
- Role: RUMSL’s primary role was to act as a park developer and facilitator. It acquired the land, secured necessary clearances, and developed the shared infrastructure like internal transmission lines. This de-risked the project for the private developers. This plug-and-play model has since been replicated for other large-scale solar parks in India.
The Vision: More Than Just a Power Plant
The creation of the Rewa Solar Park was driven by a clear and powerful vision. It was designed to address several key national objectives.
Key Objectives of the Project
- Meeting Renewable Energy Targets: The project is a significant contributor to India’s National Solar Mission and its international climate commitments.
- Providing Clean, Affordable Power: A core goal was to generate electricity at a low cost. This makes clean energy accessible and affordable for a wider population.
- Energy Security: By reducing reliance on imported fossil fuels, the project enhances India’s energy security.
- Creating a Bankable Project Template: A crucial objective was to create a new, financially sound model for large-scale solar projects. This would attract private and international investment into the sector.
- Promoting Interstate Power Sale: The project aimed to pioneer the sale of solar power across state lines, a major step in creating a truly national energy market.
A Financial and Structural Masterpiece
The Rewa Solar Park is celebrated globally not just for its size, but for its innovative financial structure. This structure made the project highly “bankable,” meaning it was seen as a secure investment by financial institutions.
World Bank Partnership
The World Bank Group played a critical role in the project. It provided a significant loan through its Clean Technology Fund. More importantly, it helped design a robust risk-mitigation framework. This international partnership gave immense confidence to investors and developers.
Payment Security Mechanism
One of the biggest risks for power producers in India is the uncertainty of payments from state-owned distribution companies (discoms). Rewa addressed this head-on.
- State Government Guarantee: The Madhya Pradesh government provided a payment guarantee. This assured developers that they would be paid on time.
- Three-Tier System: A robust three-tier payment security mechanism was put in place. This ensured liquidity and reduced payment default risk to almost zero.
This strong payment security was a key reason why developers could bid at such low tariffs. They were confident they would get their money.
The Competitive Bidding Process
The project selected its developers through a highly transparent reverse auction process. Developers bid on the tariff (price per unit of electricity) they would charge. The lowest bidders won the contracts. This competitive pressure resulted in a historic low tariff that sent ripples across the industry.
The Landmark PPA with Delhi Metro Rail Corporation (DMRC)
One of the most talked-about aspects of the Rewa Solar Park is its agreement to supply power to the Delhi Metro. This was a groundbreaking achievement.
A First in India: Interstate Open Access
This was the first time a solar project sold a large quantity of power to an institutional customer in another state.
- The Agreement: The Delhi Metro Rail Corporation (DMRC) signed a Power Purchase Agreement (PPA) to buy electricity from the Rewa plant.
- The Significance: It demonstrated the viability of “open access.” This allows large consumers to buy power directly from generators anywhere in the country. This broke the traditional model where consumers could only buy from their local discom.
How it Works
The electricity generated at Rewa is fed into the national grid. The DMRC then draws an equivalent amount of power from the grid in Delhi. This transaction is managed through a complex but efficient system of energy accounting. This arrangement provides DMRC with a long-term supply of clean, affordable energy. It also helps the metro system reduce its carbon footprint significantly.
Breaking Records: The Historic Low Tariff
The Rewa auction in 2017 was a watershed moment for the Indian solar sector. It achieved a record-low tariff that was unthinkable at the time.
- The Winning Bid: The levelized tariff for the first year was ₹2.97 per kilowatt-hour (kWh). This was significantly lower than the prevailing solar tariffs. It was also competitive with the cost of power from new thermal (coal) plants.
- The Impact: This proved that solar power could compete with conventional energy sources on price alone, without needing heavy subsidies. It reset the expectations for solar tariffs in India and globally.
This achievement was a direct result of the project’s well-designed structure. The large scale, payment security, and de-risked development model gave bidders the confidence to offer extremely competitive prices.
Technical Specifications: Inside the Solar Giant
The Rewa Solar Park is a marvel of modern engineering. Here is a look at its key technical components.
Solar Panels and Mounting
- Area: The plant covers 1,590 hectares of land. Much of this land was non-agricultural, minimizing the impact on farming.
- Panel Type: The developers used high-efficiency photovoltaic (PV) modules. These are typically polycrystalline or monocrystalline silicon panels.
- Mounting Structures: The panels are mounted on large steel structures. These structures are designed to hold the panels at an optimal angle to capture the maximum amount of sunlight. Some sections may use solar trackers. These trackers follow the sun’s path across the sky to increase energy generation.
Power Evacuation and Grid Integration
- Internal Transmission: A network of internal transmission lines collects the power generated from all three units.
- Pooling Substation: The power is then pooled at a central 220/400 kV substation within the park.
- External Connection: From the pooling substation, a dedicated high-voltage transmission line connects the park to the national Power Grid Corporation of India (PGCIL) substation. This allows the electricity to be transmitted across the country.
The Three Development Units
The 750 MW capacity is divided among three developers.
- Unit 1 (250 MW): Developed by Mahindra Renewables.
- Unit 2 (250 MW): Developed by ACME Solar Holdings.
- Unit 3 (250 MW): Developed by Solenergi Power (a subsidiary of the global firm Engie).
This multi-developer approach fostered competition and ensured timely completion.
