Supercritical success for Yokogawa1 January 2009
Yokogawa has received a contract from Aravali Power Company Private Ltd (a joint venture of NTPC, Haryana Power Generation Company and Indrapastha Power Generation Company) to supply an automation and control system for the 1500 MWe Indira Gandhi supercritical coal-fired power plant project in Haryana state, northern India. The largest power plant project in the state, the first of its three 500 MW units is planned to start up in October 2010.
Yokogawa will provide instrumentation systems for the boilers and other utilities for all three of the plant’s power generation units. The systems will include CENTUM CS 3000 DCS, DPharp EJA/EJX pressure/differential pressure transmitters, and IR8A infrared gas analysers. As part of its full turnkey project solution, Yokogawa will also provide engineering, installation, and commissioning services. This contract is estimated to be worth 12 million US dollars.
India’s power industry has been straining to keep up with the country’s recent economic growth, and the expansion of power generation capacity has become a top priority. Consequently, NTPC, India’s largest power utility, and its affiliates, plan to reach a total power capacity of 75 GW through the construction of new coal-fired power plants by 2017 (about 2.5 times the current installed capacity of 29 GW).
This is Yokogawa’s sixth project for the NTPC Group, and it directly follows last year’s contract for the 1980 MW Barh supercritical plant, which is currently under construction in Bihar state, with a scheduled operation date of October 2009.
The global IA market for power plants has been growing, says Yokogawa, due to the rising demand for electric power, especially in emerging countries such as India and China, and this trend is expected to continue, the company believes. An recent ARC study stated that sales of distributed control systems (DCS), which make up the largest segment of this market, would expand by approximately 20% between 2008 and 2010.
