SECI 1200 MW Wind-Solar Hybrid (Tranche-III) auction creates new record of Lowest tariff at Rs. 2.41/kWh

Following the issuance of the incumbent national framework – the Wind-Solar Hybrid Policy in 2018, India saw a succession of WSH (Wind-Solar Hybrid) tenders. Although there have been a few successful WSH tenders, many have received tepid responses which have led to either undersubscription or cancellation of these tenders. In a recent development, however, SECI 1200 MW ISTS, WSH (Tranche-3) auction saw oversubscription of bids by 176% and etched the record-low tariff of Rs. 2.41/kWh (US$ 0.0326/kWh).
