Solar EPC segment in the country

India has become an attractive destination for investors with 53.2 GW of large-scale solar projects in the pipeline, with another 27.7 GW of projects tendered and pending auction at the end of 2021. According to the Central Electricity Authority, India’s installed power capacity is expected to rise to 817 GW by 2030 from 393 GW as of December 2021.

Despite the challenges plaguing the sector, the developments in the Indian solar sector bode well for the future, and more Indian players are now venturing into the EPC segment. Several domestic module manufacturers are foraying into the EPC business to enhance their revenues and margins.

Expectations are high for 2022 and 2023 after a strong 2021 for the solar sector. The entry of Voltas and Siemens Gamesa into the top five is an example of new players making their mark in the EPC segment in India.

Earlier, Mahindra Susten, Vikram Solar, and BELECTRIC were the top utility-scale solar EPC service providers in the first half (1H) of CY 2021.
