The Transmission Corporation of Telangana Limited (TSTRANSCO) has floated two tender notices to set up availability-based tariff (ABT) metering along with supervisory control and data acquisition (SCADA) facilities at interconnection points for solar captive generating projects in the state.

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 two projects for which ABT and SCADA facilities are required for are:

• A 10 MW solar captive generating project Singareni Collieries Company Limited, connected at 132/33 kV SCCL Mandamarry substation in Mancherial district of Adilabad circle in Karimnagar zone
• Another 50 MW solar captive generating project of Singareni Collieries, connected at 132 kV OCM substation in Peddapally district of Karimnagar circle in Karimnagar Zone

Bidders who are interested in the 10 MW Mancherial project are expected to pay an earnest money deposit (EMD) of ₹324,283 (~$4,548). The contract is estimated to cost ₹16.21 million (~$227,343), and the last date for the submission of bids is February 28, 2020.

Interested bidders for the 50 MW Peddapally project are expected to pay an EMD of ₹321,517 (~$4,509). The estimated contract value for this project is ₹16.08 million (~$225,520), and the deadline for bid submission is February 27, 2020.

In 2018, Mercom reported that Singareni Collieries Company Limited, a government-owned company was planning to develop 300 MW of solar projects in captive mode on vacant lands at various locations of the company.  The company had estimated the entire capacity development to cost approximately ₹13,615 million (~$199.9 million) through a debt-equity ratio of 70:30. The Transmission Corporation of Telangana was to provide grid-connectivity for the projects.

Recently, the National Thermal Power Corporation (NTPC) invited bids for the operation and maintenance of a 10 MW solar project in Ramagundam, a city in the Peddapalli district of Telangana, for two years.
