The Delhi Development Authority (DDA), through the Executive Engineer (Electrical), Electrical Division No. 12, has issued a formal tender for the development of 1.8 MW of net-metered solar carport projects at two strategic locations in the capital. Executed under the Renewable Energy Service Company (RESCO) model, the project utilizes a tariff-based competitive bidding process to select a developer. The submission deadline for proposals is set for July 30, 2026, with technical bids scheduled for opening on July 31, 2026.
Alignment with Delhi Solar Energy Policy 2023
This procurement aligns with the strategic vision of the Delhi Solar Energy Policy 2023, which seeks to overcome the city’s significant space constraints through innovative deployment models. By utilizing existing parking infrastructure for solar carports, the DDA is implementing the policy’s directive to make clean energy accessible through “targeted incentives and innovative models” such as the RESCO and Hybrid RESCO frameworks. These systems allow for high-impact solar generation without requiring additional dedicated land, effectively transforming transit and utility areas into productive energy assets.
Project Scope and Site-Specific Allocations
The scope of work encompasses the comprehensive design, supply, erection, testing, and commissioning of net-meter-connected, ground-mounted solar carport power plants. These elevated structures provide essential shade for vehicles while optimizing surface area for energy generation. The total capacity is distributed as follows:
| Location Name | AC Capacity (kWp/MW) |
| District Park and NG Drain area (Outer Ring Road to Khayala Bridge) | 1,500 kWp (1.5 MW) |
| MP Green Belt, Mangolpuri | 300 kWp (0.3 MW) |
| Total Capacity | 1,800 kWp (1.8 MW) |
