Mitsubishi Heavy Industries Technical Review Vol. 54 No. 3 (September 2017)6Expansion of Coal-fired Thermal Power Generation
Business in India and Globalization of Indian
Manufacturing BaseM i ts u b i s h i H i ta c h i P o w e r S y s t e m s , L t d .

The joint venture boiler company L&T-MHPS Boilers Private Ltd. (LMB), and the joint
venture turbine/generator company L&T-MHPS Turbine Generators Private Ltd. (LMTG), whichwere established jointly by Mitsubishi Hitachi Power Systems, Ltd. (MHPS) and Larsen & Toubro(L&T) to construct high-reliability and high-performance ultra-supercritical coal-fired thermal
power plants in India, a country facing constant power shortages, are marking their 10th
anniversaries in 2017. Mitsubishi Electric Corporation (MELCO) also participates in LMTG as acontributor.
During these ten years, we have received orders for 18 boilers and 15 steam
turbines/generators in India, among which 7 boilers and 9 steam turbines/generators have started
operation. In the future, we will expand the coal-fired thermal power generation business in India
including after-sales service not only for newly-built plants, but also for existing plants and thereplacement of aging plants with ultra-supercritical power plants. Furthermore, we are promoting
our Selective catalytic NOx reduction (SCR) technology to meet new environmental regulations inIndia, aiming at the realization of coal-fired thermal power plants with much higher environmental
compatibility than ever before.
Utilizing the high quality and reliability cultivated in Indian projects, we have also delivered
boilers, pulverizers and steam turbines manufactured in India to the markets outside that country
such as Japan, the United States, Southeast Asia, and the Middle East. We will continue to utilize
our manufacturing facilities in India more widely as a manufacturing base for boilers, pulverizers
and steam turbines for global markets.

|1. LMB and LMTG, joint venture companies established by MHPS
and L&T
To "resolve the constant power supply shortage" in India and "utilize the abundant coalresources in the country," and also respond to needs for "the introduction of high-performancecoal-fired thermal power generation technology with excellent environmental compatibility" and"the development of domestic industries," MHPS established LMB and LMTG jointly with L&T in
2007, and built a boiler and steam turbine/generator manufacturing plant in Hazira, Gujarat State inWestern India (Figure 1). In 2009, we added a pulverizer manufacturing plant and a foundry toproduce pulverizers, which are main pieces of boiler equipment, and large casting parts of steam
turbine casings.

7During factory construction, to maintain the same level of quality as the Japanese factories,
the same important facilities as those in Japan were introduced under the guidance and promotionof MHPS and MELCO.
Based on a technology licensing agreement, in parallel with the construction of the plants,
MHPS and MELCO introduced their state-of-the-art technologies of ultra-supercritical power
generation equipment. In addition, many Japanese engineers were dispatched to not only introduce
the technology to all manufacturing processes of LMB & LMTG (such as quality, design,manufacture, construction, and trial operation), but also inculcated "Japanese craftsmanship" mind
in all processes.
With the introduction of hard and soft technologies, a manufacturing process meeting theglobal quality requirements was ensured, and as a result, the plant has grown into a manufacturingbase for boilers, pulverizers, steam turbines and generators.

|2. Supply records of LMB and LMTG
2.1

Supply records to the Indian market

In the ten years since the establishment of LMB and LMTG in 2007, we have received orders
for 18 boilers and 15 turbines (Figure 2). In February 2014, NPL (Nabha Power Limited) Rajpuraunit 1, which was also one of the first power plant units supplied by LMB & LMTG, was put into
commercial operation, and since then, 7 boilers and 9 steam turbines and generators have started
commercial operations. Initially, the steam temperature of 566°C for the main steam and 593°C for
the reheating steam was prevalent in Indian projects. From the establishment of the joint venturecompany, we promoted the introduction of ultra-supercritical power plants to India, which areequivalent to Japan's state-of-the-art power plants, and in 2015 received an order for NTPC (NTPCLimited) Khargone, with 600°C steam temperatures for main and reheating. This project is now
under manufacturing and site erection (Figure 3).

Supply records to the global market

As a result of the licensed technology application and the technical support in theimplementation of Indian projects, these manufacturing bases have grown and satisfy global quality
requirements. We are now able to utilize the superior competitiveness of LMB/LMTG for MHPS's
global projects, and we are actively utilizing them as manufacturing bases for boilers/pulverizers
and steam turbines.
When introducing Indian products to Japanese and other overseas customers, we invitedthem to visit our factory in India so that they could understand our manufacturing quality by seeing
the actual products during the manufacturing process in the factory. We have received orders forboiler pressure parts (6 projects), pulverizers (13 projects) and steam turbines (12 projects)
manufactured by LMB/LMTG for delivery to Japan, the United States, Southeast Asia and theMiddle East (Figure 4).

3.1

Introduction of technology to deal with new environmental regulations

In December 2015, new environmental regulations were implemented in India, which gavebirth to a huge environmental equipment market for not only new installations, but also forafter-sales service projects. Regarding the SCR technology, we are promoting its introduction toLMB through our technology licenses and supporting the NUPPL (Neyveli Uttar Pradesh PowerLimited) Ghatampur project, where the SCR technology equipment will be applied to an actual
plant for the first time in LMB.

3.2

Initiatives towards after-sales service

Three years have already passed since the start of commercial operation of NPL Rajpura unit
1, and after-sales services such as periodic inspections of plants delivered by LMB/LMTG havealso started. In addition, LMTG also conducts gas turbine inspection work making full use of its
high-speed rotation test facility, and in the future it will also expand to the after-sales services areafor equipment other than that delivered by LMB/LMTG.

3.3

Efforts to maintain and improve quality of LMB and LMTG

Based on the reflection of quality problems faced in initial projects, we continued to provide
technical support to LMB and LMTG. As a result, the culture of maintaining and improving thequality level gradually developed and globally accepted quality has been realized. It is important tomaintain and further improve this level of quality. We will continue guidance by dispatching ourpersonnel not only to the management of the joint venture, but also to the sales, design, andmanufacturing areas, so that the required level of quality can be secured. In addition, we willcontinue to dispatch MHPS's experts regularly to LMB/LMTG plants and project erection sites toconduct audits and other various improvement activities (Figure 5).

Project audit and improvement activities|4. Future prospects
In addition to newly-built plants, suggestions for the replacement of aging coal-fired plants
with supercritical or ultra-supercritical plants are being offered. We will continue to expand thecoal-fired thermal power generation facility business including after-sales services in the Indianmarket.
For global markets, we will utilize LMB/LMTG plants as one of the manufacturing bases for
MHPS's boilers/pulverizers and steam turbines, and further strengthen our competitiveness byselecting the most suitable production base for any project.
We will also promote the global utilization of human resources in the design, construction
and commissioning departments in LMB and LMTG, which have been cultivated during
technology transfers.
