Vedanta to redesign waste heat recovery plant in Goa


Vedanta plans to redesign one of its heat recovery power plants in Goa and re-optimize its turbines through the use of specialized technology to increase power generation by another 5MW, said said a senior company official.

This is in line with Vedanta’s efforts to reduce carbon footprint.

“The turbine design of our power plant will be slightly modified and it is being re-optimized. The idea is in the nascent stage. The turbine that produced 30 MW will generate 35 MW using the same amount of heat. We will ensure that heat losses and recirculation losses have been optimized through very specialized technology,” Sujal Shah, CEO of iron ore business, Vedanta Ltd, told PTI.

Vedanta has already used this technology to increase electricity production at one of its power stations in Rajasthan.

“Vedanta’s iron ore business has two power plants of 30 MW (each). Once we finish optimizing one power plant, we will replicate the same for the other,” Shah explained.

The company plans to invest in technology, he said, adding that it was just a technology upgrade for greater efficiency. Similarly, the company also plans to install a waste recovery power plant on its coke oven batteries at the newly acquired coke manufacturing facilities in Maharashtra and Gujarat.

“These plants will help us continue to supply electricity to the public grids at nominal cost and to other sources. This is a safer way to produce green energy using waste heat from coke oven batteries,” he explained.

Vedanta’s Sesa Goa iron ore business previously said it was aiming to achieve net carbon neutrality by 2050. In line with the country’s broader vision of a zero-carbon economy, the company has designed a comprehensive plan to achieve this goal.

To reduce greenhouse gas (GHG) emissions, Vedanta’s Sesa Goa iron ore business has implemented several projects such as pulverized coal injection (PCI), heat recovery power plants residual heat, massive plantations in neighboring communities, the development of green belts in mining sites and renovation. blast furnaces, among others, the company said.

Sesa Goa Iron Ore Business plans to achieve carbon neutrality gradually with the goal of further reducing GHG emissions by up to 25% by 2030.

The company is also considering a 10-tonne-per-day carbon capture, utilization and storage unit to manufacture carbon-based products. In its quest to become a net zero organization, Vedanta’s Sesa Goa Iron Ore business has adopted various green technologies and process optimization innovations.
