Solarworld Energy Solutions has received a letter of award from NTPC for the engineering, procurement, and construction (EPC) of a 250 MW solar power project in Bikaner, Rajasthan.

The estimated cost of work is ₹7.25 billion (~$80.62 million).

The tender was floated in June this year.

Solarworld will also be responsible for providing operation and maintenance services for three years.

The scope further includes completing a pre-engineered inverter room (if required) with both low- and high-tension (HT) switchgears associated with the power conditioning unit. For string inverter configurations, Solarworld must construct a pre-engineered HT switchgear room.

Solarworld will undertake site development activities, including grading and vegetation clearance, topographical surveys, and geotechnical investigations. The company must also arrange temporary power and water supply to support construction activities.

In addition, Solarworld must carry out all associated civil and electrical works for grid interfacing. This includes supplying and installing transformers, panels, protection systems, cables, and metering equipment at the 33 kV level, and facilitating the grid compliance study.

Power evacuation will be up to the 33 kV main pooling switchgear at the project owner’s pooling substation. Solarworld must lay, terminate, and connect HT cables from the block boundary to the owner’s main 33 kV pooling switchgear.

The contract also covers the supply of spare equipment and module cleaning systems, along with their installation.

Solarworld must develop internal roads, pathways, and drainage systems in line with the project site’s general layout and topography. The company must also provide a supervisory control and data acquisition system for remote monitoring and control of the inverters. This system must include complete hardware and software, as well as a weather monitoring station capable of detecting cloud cover.

Additionally, Solarworld must install dynamic reactive power compensation equipment and harmonic filters. The scope also includes deploying CCTV cameras with remote monitoring capabilities to ensure 100% coverage of the project perimeter, the entry and exit gates of the solar blocks, and the weather monitoring station.

Solarworld must design and construct foundations for tracker-based module mounting structures, including the erection of these structures and the interconnection of the solar modules.

The project will use string or central inverters with a minimum cumulative capacity of 250 MW, equipped with maximum power point tracking technology, along with the supply of associated cables, transformers, and switchgear.

The project is scheduled for completion in the financial year 2026–27.
