The National Thermal Power Corporation Limited (NTPC) has invited bids from eligible bidders for the supervisory control and data acquisition (SCADA) and weather monitoring system (WMS) package for Solapur solar power project in Maharashtra. The contract also includes one year of maintenance.

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. Availability-based tariff metering is a frequency-based pricing mechanism currently employed in India for unscheduled electric power transactions.

The last date for the submission of bids is May 28, 2020, and the pre-bid meeting will take place on May 14, 2020. The interested bidders will have to pay an amount of ₹100,000 (~$1,309.75) as the bid security deposit.

To take part in the bidding process, the bidder should have supplied and commissioned a SCADA solar PV project of 18 MW or more, which must have been in operation for at least one year. The bidder will be considered qualified if the execution of the reference work has been received directly from the owner of the project or any intermediary organization.
