In Short : Assam Power Distribution Company Limited (APDCL) has invited bids for a 400 kV/33 kV pooling substation for a 1 GW solar project in Karbi Anglong. Funded by the Asian Development Bank, the project aims to strengthen Assam’s renewable energy infrastructure. Bids are due by May 5, 2025, with completion expected within 18 months.
In Detail : Assam Power Distribution Company Limited (APDCL) has issued a tender for the development of a 400 kV/33 kV pooling substation to support a 1 GW solar power project in Karbi Anglong. This initiative is part of Assam’s efforts to enhance its renewable energy infrastructure and integrate large-scale solar power into the grid. The project is being partially financed by the Asian Development Bank (ADB).
The selected bidder will be responsible for the design, engineering, manufacturing, erection, testing, and commissioning of the substation on a turnkey basis. The project also includes installing power transformers, substation automation systems, and related infrastructure to ensure efficient power transmission. The initiative aims to strengthen Assam’s power distribution network and promote the use of clean energy.
To participate in the bidding process, interested companies must submit their proposals by May 5, 2025. The bid openings will take place on the same day. Additionally, bidders are required to provide a security deposit of ₹35 million (approximately $400,000). The project is expected to be completed within 18 months from the date of the contract award.
Eligible bidders must meet specific financial and technical criteria to qualify. Companies should have a minimum annual turnover of ₹2.8 billion (around $32.21 million) over the past five years. Additionally, they must have experience in executing engineering, procurement, and construction (EPC) contracts for air-insulated substations of 400 kV, with successful implementation of power transformers and substation automation systems in the last seven years.
The 1 GW solar power project is estimated to cost around $672.68 million. Funding for the project is sourced from the ADB ($434.25 million), the Indian government ($108.66 million), and a private sector loan ($129.77 million). A portion of the ADB financing will be allocated to the construction of the pooling substation, ensuring smooth power evacuation from the solar plant.
By investing in large-scale renewable energy infrastructure, Assam is taking significant steps toward reducing dependence on fossil fuels and promoting sustainable energy development. The pooling substation will play a crucial role in ensuring efficient solar power transmission, supporting India’s broader clean energy objectives.
