Potential Impact Study of Renewable Energy Resources on Power Transformer
Chapter One Introduction to Topic CHAPTER I 1.1Introduction: India is one of the developing countries & at the same times a fastest rising economy in the world.India along with the BRIC countries is considered as the back bone of the world’s economy.
This attraction is partially due to the lower cost of manpower and good quality production. India is now the eleventh largest economy in the world, fourth in terms of purchasing power. It is poised to make tremendous economic strides over the coming years, with significant development already in the planning stages. For development of a country, infrastructure plays a vital role.
With the opening of the Indian economy in 1990, many multinational / transnational companies were eager to invest in India. India being the second largest population of the world is the largest market for foreign multinationals. For this reason development of the infrastructure was need of the hour for the economy. ENERGY development is the key aspect of infrastructure development & demand of the developing economy. Moreover, fulfilling the energy requirement of ever growing population is herculean task. The infrastructure deficit in India is immense & India is power stressed.
The increasing vibrancy and flexibility of the Indian economy is not matched by the power sector. India was heavily relied on Conventional energy resources like thermal energy. The conventional energy development mainly depends on availability of resources like oil, coal, coke etc. Even nuclear power generation depends on availability of uranium & platinum. Conventional energy generation also results in higher carbon emission & pollution. Destroying the wastes from the conventional energy generation is the major task ahead of the country. Renewable energy Resources give the best possible solution for this problem.
Renewable energy resources can be defined as the energy resources which can be replenished, as & when they are consumed e. g. solar, wind, small hydro power, biogas etc. Knowing the potential of this form of energy resources, Indian government established a separate ministry for Renewable energy resources in 2006. Perhaps, India is the only country having separate ministry for renewable energy. Since then renewable energy market is an upcoming market in Indian power sector. With boom in the renewable energy market, there is also a rise in demand for related manufacturing equipment industries.
Transformer is one of such equipments required in power systems for transmission of power. Our aim in this project is to make a Market Potential Impact Study for transformer for renewable energy markets. 1. 2Research Methodology: The first and a very important step in market research is formulating a research problem. It is the most important stage as if the problem is wrongly defined the subsequent stages will be of no good for the purpose for which the research is being conducted, at the same time the problem must not be defined too broadly or too narrowly.
In this Project we are identifying the gap in the organizations portfolio of Transformer Business in India. We have identified that organization has no presence in the low voltage, distribution class transformer markets in India. Looking at the growth rate of Renewable energy markets and governments initiative towards the renewable energy, our main objective is to ascertain its impact on transformer business. Identifying sources of information There are two type of data resources used for the research primary and secondary data sources. Primary research data :
Primary research involves getting original data directly about the product and market. Primary research data is data that did not exist before it is designed to answer specific questions of interest to the business. • One to one interaction: Idea generation of the project is drawn from the one to one interaction with the experienced colleagues and trusted associates. • Casual Interviews: Casual interviews are the unstructured interviews. Casual interactions with the seniors, discussions with the vendors are one of the sources of primary data. • Brainstorming:
Brainstorming is the casual interaction with experts. Experts are allowed to discuss freely on a particular subject. Their newly generated ideas are registered. There may not be any time duration for such sessions. • Observations: • Existing customer enquiries & their feedbacks: Many times customer enquiries can give us the data we required. The feedbacks from the existing customers are also helpful for idea generation. Secondary research data : Secondary data is the pre- existing data, already available through books, previous researches, organizations, government documents, journals, news papers etc. Trade magazines, Journals: There are various trade magazines in power sector available. IEEMA (Indian Electrical & Electronics Manufacturers Association), Powerline magazines, ITMA (Indian Transformer’s Manufacturing Association) are some of the related associations. These associations are also working on the Renewable Energy Resources. • Newspapers: News papers are always giving the updates about the new trends, ideas, research going on around the world around. • Internet articles, websites: Internet is the huge pool of data available for secondary research.
Various search engines like Google, Yahoo etc. are useful for finding the relevant data. Websites of various Private & government PSU’s are the sources of data. Websites of PGCIL, IEEMA, ITMA, Wind Power Associations, Wind mill solution manufacturer’s, statistical agencies are of immense help. • Books: Books are always the sources of the technical data. • Statistics agencies; The statistical agencies like India Securities ltd. , which are doing their own research in various industries, are the sources of secondary data. • Government resources:
Government organizations like PGCIL, SEB’s, Ministry of New & Renewable Energy Resources are the sources of data. • Manufacturing associations: Indian Transformer Manufacturing Association (ITMA), Windmill manufacturing associations are some of the manufacturing associations, which are used as the sources of secondary data. Gathering the existing data & checking its authenticity is an important step in the research design. After the process of data gathering information, the data was tabulated and analyzed through graphs & bar charts as discussed in chapter 4 of this report. . 3Objectives: • To study the current status of renewable energy market within India. Our study will mainly concentrate on Wind Energy & Small Hydro Projects (SHP). • To ascertain the market potential for renewable energy up to 2030 & study the strategic locations of renewable energy generation within India.Find out the trends in Power sector. • To study the specifications & the categories of the transformers required for renewable energy transmission. • Establish the relationship between the volumes of transformer business due to renewable energy market. To study the present organization set-up, this can be utilized for renewable energy transformers. 1. 4Limitations of the study: There are following limitations for the research: • The primary research was limited due to wide spread of consumers. 80% of the transformer business is from the Public utilities, state electricity boards. Most of the sites are in remote places. Hence data collection is time consuming. It is very difficult to get the responses from such wide spread customers in limited time.
For this research we mainly concentrated on customer feedbacks & experiences of previous telephonic conversations. • The secondary research is mainly concentrated on the data available through government resources. This is due to the fact that majority of the decision making & forecasting is done at the central government level. As there is increase in Private participation in recent years, there is limited amount of data available for it. 1. 5Conclusion: India is developing with the rapid pace; it implies heavy investments in infrastructure.
Energy generation is the key aspect for the infrastructure growth of the country. With the government’s initiative towards clean energy development, Renewable energy sector is booming. Due to Renewable energy development, there is also increase in the private participations in power plants implementations. This scenario is conducive for the demand of the transformers required for small power projects (private as well as public). In this project we will be concentrating on impact potential study of Renewable energy on power transformers.
This will be helpful for the organization for initiating the low power, low voltage, distribution transformer’s business in India. We will ascertain its feasibility in the subsequent chapters starting with the organization’s profile.

The factory was started in 4th December 2007. The facility is capable of manufacturing high-voltage direct-current and other special application transformers.
The transformers manufactured by Siemens in India will be identical to those made in Europe, the United States and elsewhere as the technology for these comes from Nuremberg, Germany. The full technology transfer, including the know-how for design and production techniques, has been transferred through documentation as well as the training of Indian personnel in Siemens plants in Germany and elsewhere. The new plant is designed taking into consideration all the experiences gathered from other Siemens plants, which have been in operation for the past several decades.
This makes the plant unique as it applies all the best practices established in other plants – under one roof. The new plant will have 500 employees when it reaches full production capacity. The manpower and production costs account for approximately 15 percent of the sales price in India compared to about 35 percent in developed countries. The new Transformer factory will be able to address the heightened demand for power transmission equipment in the country by designing and manufacturing large transformers of power rating upto 600 MVA and 800 KV voltage class.
The factory will also produce special application transformers such as for HVDC and traction furnace applications. This factory is the latest addition to the prestigious league of 17 Transformer factories of Siemens located world-over. One of the unique features of the factory is that the transformers are manufactured in a dust-free and humidity controlled environment to ensure top class dry windings coming out of a vapour phase oven and tested under tough conditions in fully shielded test-lab. 2. 6SIEMENS IN FUTURE:
Identifying technologies with major growth potential, recognizing technologicalbreakthroughs, anticipating future customer needs and new business opportunities -Siemens experts are doing all of these things in a systematic process designed to make the company a trendsetter in as many business fields as possible. In an increasingly complex business environment marked by ever-shorter product cycles, the major challenge facing companies is how to organize R&D activities in as focused and success-oriented a manner as possible – while simultaneously making optimum use of available funds. Rigorous focus on growth markets of the future
Siemens’ Ten-Point Program was launched at the end of the 1990s to intensify the company’s focus on active portfolio management. To this day, Siemens continues to pursue the strategy defined in the program and achieve its growth targets through organic growth powered by the company’s innovative strengths, as well as through acquisitions, divestments and the formation of startups and joint ventures. In 2005, Siemens launched the Fit4More program to further tailor the strategic development of the company’s portfolio to the growth markets of the future, thus laying the groundwork for sustainable profitable growth.
In addition to defining four pillars – Performance and Portfolio, Operational Excellence, People Excellence and Corporate Responsibility – the program identified urbanization and demographic change as key megatrends that would drive its business in the future. The company’s business portfolio has changed considerably in the past few years. For example, Siemens withdrew completely from the components business (now Infineon and Epcos). Large parts of its telecommunications technology business were funneled into the joint venture Nokia Siemens Networks in 2006.
At the same time, Siemens strengthened its activities in the energy, industry and healthcare fields though extensive acquisitions. In 2006 alone, the company invested more than €6 billion to acquire companies and holdings. The current Fit4 2010 program embodies a rigorous continuation of this strategy, including further portfolio optimization with a focus on the fields of energy and environment, industry and healthcare. Siemens expects to win new orders of around INR 1 trillion in the next three fiscal years 2010 until 2012, which will be generated by government stimulus programs already announced around the world.
Green technologies are expected to account for 40 percent or approximately INR 400 billion of this total, which will significantly increase the share of the company’s revenues from its environmental portfolio in the future. Siemens based this forecast on an initial systematic analysis of the largest stimulus programs. Siemens has continued with its investment plans and focused on strengthening the local manufacturing base. In the last two years, Siemens has added three new factories in Indian energy sector alone. SIEMENS constant focus is to bring world-class and high technology products to India. Chapter Three
Theoretical Framework CHAPTER III 3. 1Energy Scenario in India Energy is the prime mover of economic growth and is vital to the sustenance of a modern economy. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. India ranks sixth in the world in total energy consumption and needs to accelerate the development of the sector to meet its growth aspirations. The country, though rich in coal and abundantly endowed with renewable energy in the form of solar, wind, hydro and bio-energy has very small hydrocarbon reserves (0. % of the world’s reserve). India, like many other developing countries, is a net importer of energy, more than 25 percent of primary energy needs being met through imports mainly in the form of crude oil and natural gas. The rising oil import bill has been the focus of serious concerns due to the pressure it has placed on scarce foreign exchange resources and is also largely responsible for energy supply shortages. [pic] India has had a negative Energy Balance for decades, which has forced the purchase of energy from outside the country. Based on available energy resources, energy sector can be classified as follows:
Few Definitions: 1. Thermal power generation: At a thermal power station in which the electric generators are steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated. The steam can be generated using • Fossil fuels like Coal / ignite • Gas • Diesel or Liquid fuel 2. Hydro-Eectric Power Generation: It is nothing but using the power of water currents to generate electric power.
Generally, hydroelectric power is created by directing water flow through a turbine, where the water causes fans to turn, creating the torque needed to drive an electric generator. [pic] 3. Nuclear Power: The energy released from an atom in nuclear reactions or by radioactive decay: esp. the energy released in nuclear fission or nuclear fusion. The radioactive materials like Thorium, uranium are used for energy generation. 4. Wind power It is the conversion of wind energy into a useful form of energy, such as electricity, using wind turbines. Wind power produced about 1. % of worldwide electricity usage; and is growing rapidly, having doubled in the three years between 2005 and 2008. 5. Geothermal power (from the Greek roots geo, meaning earth, and thermos, meaning heat) It is power extracted from heat stored in the earth. This geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. It has been used for space heating and bathing since ancient roman times, but is now better known for generating electricity.
About 10 GW of geothermal electric capacity is installed around the world as of 2007, generating 0. 3% of global electricity demand. 6. Solar power It is the result of converting sunlight into electricity. Sunlight can be converted directly into electricity using photovoltaics (PV), or indirectly with concentrating solar power (CSP), which normally focuses the sun’s energy to boil water which is then used to provide power. The largest solar power plants, like the 354 MW SEGS, are concentrating solar thermal plants, but recently multi-megawatt photovoltaic plants have been built. 7.
Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work like electricity generation 8. Tidal power, sometimes called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. Although not yet widely used, tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power Following chart shows the Indian energy scenario in 2005 & as on August 2008. It also shows the potential of various energy sectors by 2030. [pic]

As the graph below shows, it also increases the dependence on imports, which will continue into the future unless the policy changes. [pic] [pic] Estimates of Potential Capacities from Renewable Energy Sources (in MWs) (Source: India Ministry of Non-Conventional Energy Sources) [pic] Under this project we will be concentrating on the potential of Renewable Energy Resources-Wind Energy & Small Hydro projects in India. 3. WIND ENERGY: [pic] 3. 2. 1Wind resource potential: The wind power generation in the country is influenced to a great extent by the wind speed and wind power density prevalent at a particular potential location at any given point of time. The wind speed is affected to a large extent by the strong southwesterly monsoons, starting in May-June, and by the weaker northeastern monsoons in the winter months. It has been generally observed that 60-70% of the total wind power generation in the country takes place during June- October when the southwest monsoons are prevalent throughout the country.
According to a latest study, locations having an annual mean wind power density greater than 150 watts/ square meter at 30 meter hub height have been found to be suitable for development of wind power projects. 3. 2. 2Advantages of Wind Power: • It is one of the most environment friendly, clean and safe energy resources. • It has the lowest gestation period as compared to conventional energy. • Equipment erection and commissioning involve only a few months. • There is no fuel consumption, hence low operating costs. Maintenance costs are low. • The capital cost is comparable with conventional power plants. For a wind farm, the capital cost ranges between 4. 5 crores to 5. 5 crores, depending on the site and the wind electric generator (WEG) selected for installation. | |Wind |Fossil Fuel | |Availability |Usable as it exists |Have to be procured and made usable through | | |laborious and environmentally damaging | | | |processes | |Limitation on |Inexhaustible resource |Limited in reserves, expected to be completely| |availability | |exhausted in the coming 60 years | |Transportation |Used where it is available or |Has to be transported from its source site for| | |transported where needed |further processing, exposing the environment | | | |to pollution from accidents | |Environmental |Zero emission |Used in producing electricity, releasing green| |effect of use | |house gasses | |Geo-political |Reduces our reliance on oil, |Over-reliance on oil as a resource has | |implications |safeguarding national security. undermined India’s energy security, e. g.

The whole | | | |system is pollution free and | | | |environment friendly. | |
The pollution saving from a Wind Energy Generation with an average output of 4,000 kWh per year, savings have been estimated as follows: • Sulphur – dioxide (SO2): 2 to 3. 2 tonnes • Nitrogen – oxide (NO) ; 1. 2 to 2. 4 tonnes • Carbon – dioxide (CO2) : 300 to 500 tonnes • Particulates: 150 to 280 kg. 3. 2. 3The essential requirements for a Wind farm: An area where a number of wind electric generators are installed is known as a wind farm. The essential requirements for establishment of a wind farm for optimal exploitation of the wind are the following: • High wind resource at particular site. • Adequate land availability • Suitable terrain and good soil condition • Maintenance access to site • Suitable power grid nearby • Techno-economic selection of specific turbines • Scientifically prepared layout Resource |Potential (MW) |Installed capacity as on 31st March 2007 (MW) | |Wind |45000 |7092 | |Small hydro |15000 |1975 | |Biomass power / cogeneration |19500 |1184 | |Solar |4-6 kWh/m2/day |2. 74 | | |(20MW/sq. m) | | |Waste-to-Energy |2700 |43 | The sum of these renewable resource potentials, 152,000 MW, is greater than the current total installed energy generating capacity of India. 3. 2. 4Estimated Wind Power Potential in India The wind power potential on a national level, base data collected from 10 states considering only 1% of land availability, is around 46,092 MW.

The remaining 8-12% of the capital cost is incurred towards purchase of electrical equipment like the step up transformer, controls, OHT line connection to the nearest available grid and other electrical accessories. • The operation and maintenance cost per annum (inclusive of the insurance coverage) amounts to approximately Rs. 7. 00 lakh. • The expected generation of power from the WEGs on an annual basis come to the tune of 2. 5 million KWh after accounting for non operational hours of the machines due to annual repair and maintenance, non availability of cut in wind velocity or wind velocity being higher than the cut off wind velocity at a particular site. • The cost of generation of power is in the vicinity of Rs. 3. 5 / KWh. The power buy back rate varies from state to state. If wheeling is permitted then the power buy back rate can be fairly assumed as the commercial rate prevalent in a state. Wind energy generated is connected to the grid as follows: [pic] At the various stages of transmission, transformers are used for stepping-up or stepping down the voltages.

In India, hydro projects up to 25 MW station | |capacity have been categorized as Small Hydro Power (SHP) projects. While Ministry of Power, Government of India is responsible for large | |hydro projects, the mandate for the subject small hydro power (up to 25 MW) is given to Ministry of New and Renewable Energy. Small hydro | |power projects are further classified as | |Class |Station Capacity in kW | | | |Micro Hydro | |Up to 100 | | | |Mini Hydro | |101 to 2000 | | | |Small Hydro | |2001 to 25000 | | | | 3. 3. 3 Small Hydro Power Programme | |Small Hydro Power ( SHP) Programme is one of the thrust areas of power generation from renewable in the Ministry of New and Renewable | |Energy.
It has been recognized that small hydropower projects can play a critical role in improving the over all energy scenario of the | |country and in particular for remote and inaccessible areas. The Ministry is encouraging development of small hydro projects both in the | |public as well as private sector. Equal attention is being paid to grid-interactive and decentralized projects. | |Aim: The Ministry’s aim is that the SHP installed capacity should be about 7000 MW by the end of 12th Plan. The focus of the SHP programme| |is to lower the cost of equipment, increase its reliability and set up projects in areas which give the maximum advantage in terms of | |capacity utilisation. | |Potential: An estimated potential of about 15,000 MW of small hydro power projects exists in India.
Ministry of New and Renewable Energy has | |created a database of potential sites of small hydro and 5,415 potential sites with an aggregate capacity of 14,305. 47 MW for projects up to | |25 MW capacity have been identified. | | STATE WISE IDENTIFIED SMALL HYDEL SITES AND POTENTIAL | | | |UP TO 25 MW CAPACITY (as on 31. 3. 2009) | | | | | |S.

In this direction, | |the Ministry has been giving financial support to state governments/ agencies for identification of new potential SHP sites & preparation of | |state perspective plan. | |3. 3. 4 Small hydro installed capacity and progress | | The total installed capacity of small hydro power projects (upto 25 MW) as on 31. 03. 009 is 2429. 77 MW from 674 projects and 188 | |projects with aggregate capacity of 483. 23 MW are under construction. | | While in early 90s, most of the SHP projects were set up in the public sector, from last 10 years or so, most of the capacity | |addition is now coming through private sector projects. Beginning of the 21st century saw near commercialization in the small hydro sector. | |Private sector entrepreneurs found attractive business opportunities in small hydro and state governments also felt that the private | |participation may be necessary in tapping the full potential of rivers and canals for power generation.
The private sector has been attracted| |by these projects due to their small adoptable capacity matching with their captive requirements or even as affordable investment | |opportunities. In line with Government of India policy, 18 states have announced their policy for inviting private sector to set up SHP | |projects. The Government of India announced the Electricity Act in 2003, Electricity Policy in 2005 and Tariff Policy in 2006 to create a | |conducive atmosphere for investments in the power sector. Small hydropower projects are now governed by these policies and the tariff is | |decided by the State Electricity Regulatory Commissions (SERCs) as per the Tariff Policy. | |During the 10th Plan, Following have been year-wise capacity addition from SHP projects. |Year | |Target | |(in MW) | |Capacity addition during the year | |(in MW) | |Cumulative SHP installed capacity | |(in MW) | | | |2002-03 | |80 | |80. 39 | |1519. 28 | | | |2003-04 | |80 | |84. 04 | |1603. 2 | | | |2004-05 | |100 | |102. 31 | |1705. 63 | | | |2005-06 | |130 | |120. 80 | |1826. 3
