NTPC Invites Bids for a Power Project Controller for a 20 MW Solar Project in Gujarat

NTPC Limited has invited bids for the supply, installation, and commissioning of a power project controller (PPC) system and development of project dynamic model and related grid-compliance study for the 20 MW solar project at Gandhar in Gujarat.

The bidding document requires the contractor to provide a complete PPC system for the solar project with all accessories, auxiliaries, and associated equipment and cables for the safe, efficient and reliable operation of the solar project. The document also mentions that the contractor should fully comply with the grid connectivity regulations.

The last date to submit the bids is June 29, 2021, and the bids will be opened on June 30.

The contract period has been set as three months. The guarantee period for the equipment supplied will be 18 months from the date of material receipt or 12 months from the date of operational acceptance of the work to be carried out, whichever comes first.


The successful bidder will be required to furnish the contract performance bank guarantee for 3% of the total package value within 30 days of the placement of the award.

The bidder should include in his proposal all the hardware, software, panels, networking equipment, and associated cables needed for the interface with the supervisory control and data acquisition (SCADA) system and inverters. The PPC system should be suitably designed to directly and independently control the individual solar inverters. The bidder should integrate the PPC system with the existing SCADA system and inverters.

Micro and small enterprises (MSEs) would be allowed benefits under this tender. In the case where splitting of quantity is possible, the MSEs quoting price within the price band of lowest (L1) + 15% will also be allowed to supply a portion of requirement by bringing down their price to L1 price in a situation where the L1 price is from someone other than an MSE. Such an MSE will be allowed to supply up to 25% of the total tendered value.

However, when splitting of quantity is not possible, participating MSEs quoting price within the price band of L1 + 15% will be allowed to execute the package by bringing down their price to L1 price in a situation where the L1 price is from someone other than an MSE.

The total amount of liquidated damages for delay under the contract will be subject to a maximum of 5% of the total contract price.

The contractor will not be allowed to sub-contract works to any subcontractor or subvendor from a country that shares a land border with India unless such a subcontractor is registered with the competent authority.

In August last year, Bharat Heavy Electricals Limited (BHEL) floated a tender for 5 MW of power conditioning units for NTPC’s 20 MW solar project in Gandhar and had also issued a tender for string monitoring boxes with wireless communication for the same project.
