No.7 AUTUMN 2015　5To what extent can supercritical pressure power systems reduce CO2 emissions compared with conventional systems? The reduction in CO2 emissions over the course of a year from introducing high-efficiency supercritical pressure power systems comes to 450,000 tons with a 660 MW generator and 540,000 tons with an 800 MW generator (see Table 2). In other words, with these you can expect a reduction of roughly 12% in CO2 emissions compared with the conventional subcritical pressure power systems. As you can see from this, promoting supercritical pressure power systems is an extremely effective measure for carbon reduction that can boost the power generating efficiency of thermal power and reduce emissions of CO2, the amount of coal used, and fuel costs.CO2 emissions ***Type of power generation660 MW generator(1unit)800 MW generator(1unit)(1) Subcritical pressure3.6 million tons 4.36 million tons (2) Supercritical pressure3.15 million tons3.82 million tons(2) - (1)-450,00 tons-540,000 tonsTable 2.

From the orders we have received to date, we have been praised for our equipment’s high-performance and dependability. Not only that, but I would say that erecting an integrated structure for sales, engineering, design, procurement, manufacturing, construction, and services through the establishment of TJPS has been an advantage for us in acquiring orders. Moving forward, the power plants in Kudgi (which was the rst to order from TJPS), Meja, and Darlipali will sequentially begin operating from 2016 onward, which will lead to assessments of our track record. I believe that maintaining “made in India” quality and ensuring dependability through technical instruction from Japan on the basis of this track record will lead to the acquisition of further orders in the future. It will also be crucial to develop local human resources underpinning their engineering abilities, and not just manufacturing techniques. The way you position HR development using HIDA has changed, hasn’t it? Yes. We have shifted away from training to learn manufacturing techniques for the launch of a new plant towards training to develop comprehensive engineering abilities. Between 2009 and 2012 we used HIDA (AOTS back then) programs to accept engineers who were candidates for line foreman at the TJPS Chennai Plant to the Toshiba Keihin Product Operations with the main goal being to have them learn Japanese and manufacturing techniques. Afterwards, they have contributed to achieving our rst “made in India” products by the company. In 2014, we carried out training by inviting engineers in charge of engineering at the TJPS Gurgaon Ofce. From this, we learned that improving their comprehension as a result of learning work approaches and skills made it easier to engage in mutual communication. Having them learn how we tackle work at our company, deepening their understanding of our products, and having them acquire management techniques such as production management and vendor management were enormously meaningful in terms of allowing the Toshiba Group to promote engineering activities in other countries, including India, in the future. I would like to see all of the trainees acquire comprehensive knowledge related to engineering in Japan and then play an active role locally after returning home in order to live up to our customers’ expectations for everything from accepting projects through to delivery. We’ve gotten a good sense for how you are promoting exports of Japanese infrastructure technology, while at the same time working to reduce the impact on the global environment using outstanding Japanese technology. Thank you very much for talking with us today. ＊ The temperature and pressure of the steam generated in the boiler must be increased higher to boost the power generating efficiency. Subcritical refers to systems with main steam pressure of 17 MPa and steam temperature of 538℃, while supercritical refers to systems where these values are 25 MPa and 566℃, respectively.
