A lead plant at HZL Dariba was commissioned in 2010-11 and around 15-20 ton of steam was venting off this plant till 2015. The challenge was to channelise this huge amount of steam and de-mineralised water to generate power.

The HZL team conducted a steam audit of Dariba Smelting Complex and found that steam venting from DSC lead can be utilised in CPP power cycle. The team analysed different options with support from the in-house talent and after a lot of research and engineering with the OEM, the team found that DSC lead can be utilised in LPH-2 & 1 extraction of 80 MW turbine installed at Dariba power plant. HZL completed the necessary modifications by carrying out all IBR procedures and commissioned the system in 2015.
