Renaissance Solar to Invest Rs 5,000 Cr in Tumakuru Corridor
Renaissance Solar and Electronic Materials plans a Rs 5,000 crore investment in the Chennai-Bengaluru Industrial Corridor to set up a solar plant.

In a major boost to Karnataka's industrial landscape, Renaissance Solar and Electronic Materials (RSOLEC) has announced its intention to invest Rs 5,000 crore in the Chennai-Bengaluru Industrial Corridor (CBIC). The massive investment is slated for the Tumakuru region, marking a significant step forward for the state's manufacturing sector.
The announcement was made by Karnataka Minister for Large and Medium Industries, MB Patil, following high-level discussions at Khanija Bhavan. The meeting included RSOLEC Chairman and CEO Milind S. Kulkarni, and serves as a reinforcement of the company's earlier commitments made during Invest Karnataka 2025.
Massive 5 GW Solar Manufacturing Plant Planned
The India-US-based enterprise, which already maintains a significant global footprint in the solar sector—specifically in wafer fabrication and single-crystal silicon growth—aims to expand its operations significantly. The company is looking to secure 100 acres of land within the industrial corridor to establish a state-of-the-art 5 GW solar ingot and wafer production facility.
This facility is expected to be a cornerstone for renewable energy manufacturing in the region. If the project moves forward according to the current timeline, manufacturing operations are projected to commence by mid-2028.
Infrastructure and State Support
To support such a large-scale operation, the company has outlined specific utility requirements. These include:
- Electricity: A dedicated supply of 80 MW.
- Water: Access to 10 MLD of water daily.
Minister MB Patil stated that these requirements would be viewed positively by the government. Furthermore, the company has requested a Special Incentive Package from the State Government to assist with the substantial capital outlay. These discussions regarding fiscal backing are currently being handled at the highest levels of the state administration.
The review meeting was attended by several key officials, including Principal Secretary S. Selvakumar, Commissioner Khushboo Goyal, and Karnataka Industrial Areas Development Board CEO Govind Reddy, ensuring that the project receives the necessary administrative attention.
