GAIL (India) has invited bids for the design, engineering, procurement and supply, construction, erection, testing, commissioning, and operation and maintenance of a 7.75 MW grid-connected floating solar project at Vijaipur in Madhya Pradesh.

The last date for submitting bids is October 29, 2024. Bids will be opened on October 30.

The project site is situated within the GAIL Vijaipur complex.

Bidders will also be responsible for the project’s five-year operation and maintenance.

They must construct a central monitoring and control station with SCADA, PPC panel, and associated equipment at an identified location within the solar project premises.

The identified location is tentative and may be changed during detailed engineering per site conditions.

Bidders must pay an earnest deposit of ₹4.25 million (~$50,626).

In terms of cable sizing, for applications with a 33kV voltage level, the cable size must adhere to protection time grading requirements. The protection time should be at least 0.3 seconds to ensure safety and system integrity.

Regarding SCADA, the project requires two licenses for remote monitoring, with the provision for concurrent viewing by all users.

if required, provisions should be made for data telemetry and remote communication with the relevant Regional Load Dispatch Center.

For DC and LT (Low Tension) power cables, the voltage drop between the module and the inverter transformer must be limited to 3% of the rated voltage. The maximum allowable voltage drop for all LT cables is also capped at 3%.

The DC system voltage should be designed for 125V or 250V, with auxiliary voltage supplied by a 110V or 220V battery. This aspect will be finalized during the detailed engineering process.

Only Class-I and Class-II local suppliers are eligible to participate in the bidding process.

Last December, GAIL invited bids for the design, supply, construction, erection, testing, and commissioning of 600 MW (6 x 100 MW) of solar power projects at the Khavda Solar Park in the Kutch region of Gujarat.

Earlier, the company had invited bids for hiring a project management consultant to set up a 10 MW ground-mounted solar power project at GAIL’s Vijaipur Complex.
