NTPC's Sipat station to produce lightweight aggregate from fly ash

The Sipat station of the National Thermal Power Corporation (NTPC) in Chhattisgarh’s Bilaspur district will produce lightweight aggregate from fly ash.

“The preparation of detailed project report (DPR) was in the final stage and the project for producing lightweight aggregate from the fly ash generated at the station would soon take shape,” Group General Manager of NTPC Sipat Asim Kumar Samanta said. It is a pilot project and will be completed within two years, he added.

The 2980-MW Sipat super thermal power station is the first super critical technology based power station of the NTPC. The beneficiary states include Chhattisgarh, Madhya Pradesh, Maharashtra, Gujrat, Goa, Daman and Diu, Dadra and Nagar Haveli. Maharashtra is the biggest consumer, followed by Gujarat.

The Sipat station is an environment-friendly plant of the NTPC, based on super-critical clean coal technology. In the current financial year, the station had generated 6103.5 million units of electricity at a plant load factor (PLF) of 97% as on June 27, 2016. In financial year 2015-16, it had generated 22,284.84 million units of electricity at a PLF of 85.13%, which was 2.3% more than last (2014-15) financial.

The station is generating about 11,000 metric tonnes of fly ash every day. The disposal of fly ash for clean environment had been a daunting task for the country’s largest power producer. The Sipat plant was working on a plan for its utilisation in manufacturing different fly ash-based products.

The plant was also manufacturing fly ash bricks. “The entire township and the buildings inside the plant had been built by fly ash bricks,” Samanta said, adding that efforts were on to utilise the fly ash in the proposed four-lane of highway between Raipur and Bilaspur. He added that the fly ash generated at NTPC stations is ideal for use in the manufacture of cement, concrete, concrete products, cellular concrete products, bricks or blocks or tiles etc.
