NTPC has floated a tender for centralized monitoring analytical tool for the 250 MW Mandsaur solar PV project in Madhya Pradesh.

The last date for the submission of bids is May 18, 2020.

The scope of work requires the installation of the internet of things (IoT) gateway at the site to acquire data from Modbus TCP, a serial communications protocol.  Also, a content management system (CMS) will be implemented. The CMS implementation will be a parallel activity, and it will not impact the existing SCADA systems. The CMS will be a redundancy system for supervisory control and data acquisition (SCADA) with real-time data of the project anytime and anywhere.

The period of contract will be for six months, and the firewall installed in all five blocks of NTPC’s Mandsaur will be configured for blocking of traffic from the internet to the SCADA system. The analyzed data will be handed over to NTPC after the completion of the contract in a suitable industry-standard format.

Interested bidders will have to submit a bank guarantee if the earnest money deposit (EMD) amount is more than ₹20,000 (~$267).

Special treatment will be given to micro, and small enterprises (MSEs) in an attempt to give preference to the ‘Make in India’ initiative, and purchase preference will be given to local suppliers.

Interested bidders will be required to furnish the details of experience like work orders, purchase orders, letters of award, or completion certificate in support to meet the qualifying requirements.

NTPC will award the contract to the successful bidder whose bid has been determined to be the lowest evaluated bid. If required, NTPC may place separate orders for supplies and services.

The local supplier will be required to provide relevant attachment of price bid and the declaration that the items offered to meet the minimum local content. In case the total bid price is more than ₹100 million (~$1.33 million), the local supplier should be required to provide a certificate from the cost auditor of the company giving the percentage of local content.

Earlier, NTPC had invited bids for the SCADA and weather monitoring system package for Solapur solar power project in Maharashtra. The contract also included one year of maintenance. The SCADA systems are used to monitor and control a project or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining, and transportation.

Recently, the Transmission Corporation of Telangana floated two tender notices to set up availability-based tariff metering along with SCADA facilities at interconnection points for solar captive generating projects in the state.
