Share

State-owned Bharat Heavy Electricals Ltd (BHEL) has invited bids to supply, install and commission 1,250 kW, three-phase, grid-connected power-conditioning units (PCUs) for 129 MW of solar PV in Telangana.

A total of 104 PCUs will be tendered for the four solar project sites: 50 MW Ramagundam (40), 39 MW Yellandu (32), 30 MW Manuguru (24) and 10 MW STPP (8).

To be eligible, vendors should have a cumulative track record of supplying and commissioning PCUs for at least 50 MW of capacity — with each PCU rated at a minimum of 1 MW — within the last three years. Also, prospective vendors should have service centres in India.

The PV plants will feature an integrated supervisory control and data acquisition (SCADA) system, whereby all the PCUs will be integrated with other data systems such as solar array string monitoring, weather monitoring and HT side transformers/breakers monitoring. Accordingly, the PCUs should have the necessary communication protocol and output ports to facilitate SCADA interfaces.

The project completion period is 12 weeks from the date of approval. Vendors must provide comprehensive warranties for 60 months from the date of commissioning, or 66 months from the date of supply — whichever is earlier. The deadline for bid submissions is May 27. Bids will open the same day.
