State-owned engineering major Bharat Heavy Electricals Limited (BHEL) is setting up a 10 MW(AC) grid-connected solar power plant for Gujarat Narmada Valley Fertilizers and Chemicals at Charanka Solar Park in the state of Gujarat.
The selected bidder is required to supply eight numbers of 1250 KW (minimum), 3-phase, grid-connected power conditioning units (PCUs)—combinations of an inverter panel, a DC combiner panel and an AC combiner panel—along with external ducts and spares.
The scope of work also includes installation and commissioning of the supplied units at the project site for synchronizing the generated AC power with LV side of a transformer that connects to 33 KV grid on HV side. Supply and installation of the integrated SCADA system for the overall power plant is within BHEL’s scope.
The PCUs should be transformerless and have inbuilt microprocessor-based maximum power point tracker (MPPT) to maximize energy drawn from the solar PV array. These should be designed for maximum DC input voltage of 1000V. Further, the vendor is required to confirm that the PCUs are suitable for overloading of DC input power up to 30%.
To be eligible, the bidder should have supplied and commissioned cumulative PCU capacity of at least 100 MW. The PCUs must carry comprehensive warranty for 60 months from date of commissioning or 66 months from date of supply, whichever is earlier.
Delivery date is November 19.
