Commenting on the auction results, JMK Research stated: “The tariffs seen in the last two auctions, i.e., earlier SECI 2 GW with INR 2.36/kWh tariff and this one are highly aggressive. The low tariff trends can be a desperate situation wherein developers are looking to take advantage of the current situation wherein only safeguard duty of 14.9% is applicable.”

JMK cited two possible reasons for such low tariffs: “Auctions completed before a formal notification of basic customs duty (BCD) applicability will get a passthrough under “Change In law” provision.

“The module prices are also likely to fall further with the increasing gap in the demand-supply situation in the next few months due to slowdown triggered by Covid-19 pandemic.”

According to the JMK Research price tracker, in January-July 2020 period, prices of multi-crystalline modules have fallen by more than 15% in the Indian market.
