Emerson Process Management has won an order from NTPC Ltd to provide automation technologies and expertise for two new 800 MW supercritical generating units at the Darlipali Super thermal power plant in the Sundergarh District, Odisha, India. This aims to help meet the energy needs of this region of India.

“Supercritical technologies boost the efficiency of coal-based electricity generation, while reducing carbon and other emissions, but the high temperatures and pressures involved make them more challenging to control,” explained Dr Amit Paithankar, Managing Director, Emerson Process Management, India. “Our automation specialists have proven expertise and our Ovation™ control system is in more than 300 of these complex units worldwide. We welcome this opportunity to apply that experience to these important national assets.”

Unit 1 commissioning is projected to be in December 2017 and Unit 2 will commence three months after. Ovation systems will be installed and commissioned by Emerson project teams. They will monitor and control each unit’s supercritical boiler and critical balance-of-plant processes and equipment.

The company will provide its Rosemount® Analytical online steam water analysis system and continuous emissions monitoring system, Rosemount pressure and level transmitters, and additional instrumentation.
