Detailed Project Allocation and Pricing Synthesis
The auction results were anchored by the 2,000 kW Visva Bharati University project, which alone accounted for nearly 45% of the total capacity awarded in this tranche. While the cornerstone project saw record-low pricing, smaller installations in geographically remote areas, such as Agartala, commanded a significant premium.
The Anchor Project
- Visva Bharati University (Bhirbhum): Secured by Renergo Developers Private Limited at a tariff of ₹2.94/kWh. As the largest single allocation (2,000 kW), this project set the floor for the auction’s pricing landscape.
Central Sanskrit University (CSU) Network
The CSU projects represented the widest logistical challenge, spanning diverse geographies from Thrissur in the south to Kangra in the north. Tariffs for these projects scaled upward based on system size and location.
- Jaipur (400 kW): Won by GP Eco Solutions India Limited at ₹3.04/kWh.
- Devprayag (200 kW): Won by Renergo Developers Private Limited at ₹3.19/kWh.
- Puri (400 kW): Won by Renergo Developers Private Limited at ₹3.24/kWh.
- Lucknow (90 kW): Won by Renergo Developers Private Limited at ₹3.35/kWh.
- Bhalwal (220 kW): Won by Renergo Developers Private Limited at ₹3.35/kWh.
- Sringeri (50 kW): Won by Cleanco Renewables Private Limited at ₹3.50/kWh.
- Thrissur (140 kW): Won by Renergo Developers Private Limited at ₹3.65/kWh.
- Kangra (100 kW): Won by Renergo Developers Private Limited at ₹3.65/kWh.
- Bhopal (80 kW): Won by Renergo Developers Private Limited at ₹3.14/kWh.

Operational Scope and Developer Responsibilities
In accordance with the tender guidelines, selected developers are tasked with a comprehensive lifecycle commitment. This “cradle-to-grave” responsibility ensures the stability of the solar assets throughout their operational life.
- Project Execution: Full responsibility for design, engineering, supply, and civil works, including the secure storage of all solar components.
- Regulatory Navigation: Developers must manage all necessary No Objection Certificates (NOCs) from relevant DISCOMs and facilitate the integration of net metering.
- Technical Compliance: All installations and grid connectivity must adhere strictly to the regulations set by the State Electricity Regulatory Commission (SERC) and the Central Electricity Authority (CEA).
- Long-Term O&M: Successful bidders are committed to the operation and maintenance of the systems for the entire lifespan of 25 years (the full PPA term). This includes all equipment replacement costs and insurance coverage.
Bidding Context and RESCO Framework
This auction was conducted under the Renewable Energy Service Company (RESCO) mode. In this framework, the beneficiary institutions—primarily central universities and government offices—avoid all upfront capital expenditure. Instead, the developer bears the total investment and maintenance costs. The host institutions provide rooftop space and agree to purchase the generated electricity at the pre-determined tariff for the 25-year duration of the PPA. This model remains a critical driver for clean energy adoption among government entities, shielding them from the capital risks of solar infrastructure while providing immediate relief from rising grid tariffs.
