Duty passthrough to lift tariffs by 50-70p/unit for up to 6 GW of solar projects

The Ministry of New and Renewable Energy’s decision to treat the basic customs duty (BCD) on solar cells and modules as a “change in law” and allow for its passthrough could raise the tariff by 50-70p/unit of electricity2 for eligible projects. The increased tariff will remain well below the average power purchase cost for DISCOMs in India. However, more importantly, this announcement brings partial relief for up to 6 GW of solar projects that are already seeing elevated project costs as they are set to achieve COD or import modules this fiscal year.
The solar power industry has already seen a sharp rise in module prices in the last two years. This has been further aggravated by the imposition of 40 percent BCD on the import of modules and 25 percent on the import of cells, effective April 1, 2022. Though the move is intended to encourage domestic manufacturing of solar modules and cells and reduce reliance on imports, it increased project costs by 25 percent, depressing developers’ already meagre returns.
The BCD imposition was likely to impact 17 GW of projects bid between October 1, 2019, and March 9, 2021. These projects were likely to procure modules after April 1, 2022, and could not have factored the customs duty into their bid tariffs.
Says Manish Gupta, Senior Director, CRISIL Ratings, “Based on our discussions with industry players, we estimate that for 50–60 percent of the 17 GW capacity, modules may be procured domestically, keeping it out of the ambit of duty.” For another 10-15 percent of such capacity, modules were imported before the BCD imposition. Hence, treating BCD as a “change in law” event will benefit the remaining capacity of up to 6 GW, making the projects economically viable.
These projects were bid at tariffs ranging from Rs 1.99/unit to Rs 2.92/ unit, with only 20 percent of the projects being at a tariff of more than Rs 2.55/ unit, thus the increased tariff post passthrough is expected to be in the range of Rs 3-3.2/unit, keeping them cost-competitive compared to average power procurement costs for DISCOMs in India.
