basics of whisky in india

ndia consumes 48% of the world’s whisky. It is the fastest-growing market and the largest producer of the spirit. But what exactly are we making and drinking?
Whisky is decidedly the spirit of choice in India—we consume almost half the whisky produced worldwide. From the cheapest Indian-made foreign liquor (IMFL) variant—whisky makes for almost 90% of IMFL—to limited-edition single-malt Scotch, people are drinking more whisky today than ever, spending anywhere between Rs50 per 25ml peg for a McDowell’s at a Paharganj bar in Delhi to Rs1,500 for a small Johnnie Walker Blue Label at a five-star hotel. While gin is going through something of a resurgence, it is still whisky that racks up the numbers, with a more-than-healthy lead over every other alcoholic beverage.
Whisky, in the classical understanding, is an alcoholic beverage made from fermented grain mash. These grains—barley, maize, wheat, rye, etc.—are malted and fermented, and can be used in various combinations or on their own to make whisky.
Ground malted barley is soaked in warm water to extract sugars. The sweet liquor called wort is drained and transferred to fermentation tanks. Yeast is added to this to break down the sugars to alcohol. The fermentation results in a liquid called wash, which is then distilled. Most companies distil the liquid twice but sometimes it is distilled thrice. The distilled whisky is then stored in wooden barrels for maturation.
In India, most of the whisky is made from molasses—the dark, viscous by-product obtained by refining sugar from sugarcane. Fermented molasses are boiled to extract alcohol, which is distilled. The distillation results in a neutral spirit with 96% alcohol by volume, which forms the base of all IMFL. This is blended with a small amount of Scotch for flavour, and voila, we have Indian-made whisky.
“The major difference between the molasses-based and grains-based whisky is at the distillation stage,” says Nikam of Amrut, which makes both kinds of whiskies. “When we use the molasses base, we distil the alcohol till it becomes neutral and doesn’t have any characteristic flavour. For grains, we do an incomplete distillation so part of the flavour from the grains is there before it goes into barrels to mature.”
Amrut, which was established by Radhakrishna Jagdale in 1948, produces spirits from vodka to gin, including Amrut single malt whisky, which is exported to more than 25 countries.
According to Nikam, Amrut produces about 6 million nine-litre cases of liquor annually, 35,000 of which are single malt whisky. The company exports at least 60% of its single malts. As the company tries to expand beyond its key southern markets, Amrut is planning to increase its single malt production to 100,000 cases by 2022, half of which Nikam hopes will be consumed in India.
Globally, making whisky is a strictly regulated business. For example, in 2008, Europe passed a directive asserting that whisky was an alcoholic drink produced exclusively by the distillation of a mash made from malted cereals. This immediately excludes most “Indian whiskies” from the category.
Scotland took this a step further the next year, introducing the Scotch Whisky Regulations 2009 (SWR). The new regulations gave the precise definition of different kinds of whisky and the difference between a single grain and a single malt. The document has stringent guidelines on regional and geographical indications, production and maturation of Scotch. According to the SWR, Scotch can’t be made or matured outside Scotland. For a whisky to be called Scotch, it has to be made in Scotland, with set raw materials, and has to be aged within the country for three years or more.
Much of the whisky-producing world—from the US to Japan and Australia—has stuck to similar guidelines regarding the product and its manufacturing process. American bourbon whiskey, for example, must mature in new oak barrels, which are then used to age Scotch. In India, however, there are multiple regulations governing consumption age, on obtaining liquor licences and the tax structure—leading to arbitrary and exorbitant prices. But there are hardly any rules that benefit the end user, such as differentiating whisky from rum, or even country liquor for that matter.
The only stricture, according to a 2005 Bureau of Indian Standards publication, is that whisky should be made either from a neutral spirit that matches its standards, or a Grade I rectified spirit, or a mix of both. It is this laxity on the part of the Bureau of Indian Standards that allows for so many different spirits, many of which are artificially coloured, to be bottled and legally sold as whisky.
Yet last year, for the first time, the Union government standardized alcohol as a consumable product beyond tax purposes, and the Food Safety and Standards Authority of India (FSSAI) came up with the draft Food Safety and Standards (Alcoholic Beverages Standards) Regulations, 2016, which defined various kinds of alcohol and their types.
According to the draft, “Whisky is an alcoholic beverage made from neutral grain spirit or rectified grain spirit, or neutral spirit or their mixture or is made by distilling the fermented extract of malted cereal grains such as corn, rye, barley; or molasses.”
At the same time, both rum and country liquor are defined by the FSSAI in pretty much the same way. Going by this definition, it’s hard to establish the difference between these three kinds of alcohol.
ost whisky made in India is aged briefly because the higher temperatures result in quicker evaporation of the spirit during the maturation stage, a phenomenon known as “the angels’ share”. The draft regulations require that whiskies in India, when labelled matured, “shall be matured for a period of not less than one year in wooden oak, wooden vats or barrels”. This means that much of the whisky that falls in the IMFL category is not aged at all.
Understandably, there has been retaliation, mostly in Europe, against the rise of India-made “cheap whiskies”. In its 2013 annual report, the Scotch Whisky Association (SWA) urged European Union-wide action against the “extremely worrying” quantities of cheap Indian blends being imported into the EU.
“There is no compulsory definition of whisky in India, and the Indian voluntary standard does not require whisky to be distilled from cereals or to be matured,” according to a 2014 PTIreport which quoted the SWA report. “Very little Indian ‘whisky’ qualifies as whisky in the EU owing to the use of molasses or neutral alcohol, limited maturation (if any) and the use of flavourings. Such spirits are, of course, considerably cheaper to produce than genuine whisky.”
Whisky distillation came to India with the British in the 19th century. Edward Dyer, father of Reginald Dyer, the infamous British colonel who ordered the Jallianwala Bagh massacre, was the pioneer of whisky-making in India. Dyer senior set up a distillery in Kasauli in the 1820s. Kasauli, in the Himalayan highlands at 6,000ft above sea level, has climate similar to Scotland, with the added advantage that there was fresh springwater nearby. The distillery later moved to Solan.
Dyer brought equipment and copper stills from Scotland, some of which are still in use. The distillery’s Solan No.1 was the best-selling whisky in India for over a century but today, the only malt whisky from the Himalayas is struggling to find takers.
How molasses took over grains is actually quite an interesting story.
Across the world, people use agricultural surplus to make alcohol. Barley in Scotland; wheat, corn and rye in the US; rice in some Asian countries; and sugarcane in India. This is why molasses became prominent in Indian alcohol production.
In 1947, entrepreneur Vittal Mallya bought United Breweries, a group of five breweries in south India that made beer for British troops. At one time, United Spirits Ltd, the group’s alcoholic beverages company, was the largest spirit producer in India, with around 60% of the market share. Its brands included locally produced Bagpiper, Royal Challenge, McDowell’s No.1, and Antiquity, Jura and Dalmore single malt Scotch whiskies.
Diageo Plc., the world’s largest producer of spirits, now owns USL and the business is now called Diageo India.
“Diageo India is a market leader in both Scotch and IMFL segments and our brands are all available at distinctive price points in the overall whisky category,” says Thomas. “With each brand attracting a different set of consumers driven by varying taste preferences and affordability, we see sufficient interest across all the segments.”
But if you want to reach the masses, pricing your product at Rs300 per 750ml bottle, it simply isn’t possible to make it with grains, says Nikam. “At that price point, the product can only be made from neutral spirits,” he says.
Entry-level whisky is the most volatile space of the market. “Those people who were consuming country liquor will slowly move up to entry-level IMFL,” says Nikam.
“If you take the whiskies in the Rs300 price range and change the price by Rs5, you’d suddenly gain or lose 50% of your market share,” says drinks consultant Anand Virmani. “Frankly speaking, at that range, you can’t really make a good whisky.”
But consumers are upgrading as a result of increased exposure, better knowledge and more disposable income. Brands are taking notice. “Several brands in the Rs600-800 range have repackaged themselves,” says Virmani. “Many now have a limited edition kind of product too in the mix. It is an evolving market.”
IMFL has its place. “It is okay in the context in which it is being consumed,” says London-based whisky writer Joel Harrison. “Even though it isn’t the drink of the connoisseur, it is sweet and accessible, and can be easily consumed neat or mixed into a long drink.”
“There’s been significant improvement in the distillation technology and, therefore, even the alcohol made from molasses in most cases is of extremely good quality and does not make much of a quality difference,” says Sridhar Pongur, joint managing director at Goa-based John Distilleries Pvt. Ltd, which makes the Paul John brand of single malt whiskies. “However, since maturation is not normally done in India, there is definitely a difference in taste and flavour.”

Why wind energy?

Why wind energy?

The project is environment friendly.
India has good wind potential to harness wind energy.
A permanent shield against ever increasing power prices. The cost per kwh reduces over a period of time as against rising cost for conventional power projects.
The cheapest source of electrical energy. (on a levelled cost over 20 years.)
Least equity participation required, as well as low cost debt is easily available to wind energy projects.
A project with the fastest payback period.
A real fast track power project, with the lowest gestation period; and a modular concept.
Operation and Maintenance (O&M) costs are low.
No marketing risks, as the product is electrical energy.
A project with no investment in manpower.
A country like India or any region where energy production is based on imported coal or oil will become more self-sufficient by using alternatives such as wind power. Electricity produced from the wind produces no CO2 emissions and therefore does not contribute to the greenhouse effect. Wind energy is relatively labour intensive and thus creates many jobs. In remote areas or areas with a weak grid, wind energy can be used for charging batteries or can be combined with a diesel engine to save fuel whenever wind is available. At windy sites the price of electricity, measured in Rs/kWh, is competitive with the production price from more conventional methods, for example coal fired power plants.

Limitations
Wind machines must be located where strong, dependable winds are available most of the time.
Because winds do not blow strongly enough to produce power all the time, energy from wind machines is considered "intermittent," that is, it comes and goes. Therefore, electricity from wind machines must have a back-up supply from another source.
As wind power is "intermittent," utility companies can use it for only part of their total energy needs.
Wind towers and turbine blades are subject to damage from high winds and lighting. Rotating parts, which are located high off the ground can be difficult and expensive to repair.
Electricity produced by wind power sometimes fluctuates in voltage and power factor, which can cause difficulties in linking its power to a utility system.
The noise made by rotating wind machine blades can be annoying to nearby neighbors.
People have complained about aesthetics of and avian mortality from wind machines.

Biofuels

Biofuels are liquid or gaseous fuels primarily produced from biomass, and can be used to replace or can be used in addition to diesel, petrol or other fossil fuels for transport, stationary, portable and other applications. Crops used to make biofuels are generally either high in sugar (such as sugarcane, sugarbeet, and sweet sorghum), starch (such as maize and tapioca) or oils (such as soybean, rapeseed, coconut, sunflower).

Categories of biofuels

Biofuels are generally classified into three categories. They are
  1. First generation biofuels - First-generation biofuels are made from sugar, starch, vegetable oil, or animal fats using conventional technology. Common first-generation biofuels include Bioalcohols, Biodiesel, Vegetable oil, Bioethers, Biogas.
  2. Second generation biofuels - These are produced from non-food crops, such as cellulosic biofuels and waste biomass (stalks of wheat and corn, and wood). Examples include advanced biofuels like biohydrogen, biomethanol.
  3. Third generation biofuels - These are produced from micro-organisms like algae.

Biodiesel and its benefits

Bio-diesel is an eco-friendly, alternative diesel fuel prepared from domestic renewable resources ie. vegetable oils (edible or non- edible oil) and animal fats. These natural oils and fats are primarily made up of triglycerides. These triglycerides when reacted chemically with lower alcohols in presence of a catalyst result in fatty acid esters. These esters show striking similarity to petroleum derived diesel and are called "Biodiesel". As India is deficient in edible oils, non-edible oil may be material of choice for producing biodiesel. Examples are Jatropha curcas, Pongamia, Karanja, etc.
The benefits of using biodiesel are as follows
  • It reduce vehicle emission which makes it eco-friendly.
  • It is made from renewable sources and can be prepared locally.
  • Increases engine performance because it has higher cetane numbers as compared to petro diesel.
  • It has excellent lubricity.
  • Increased safety in storage and transport because the fuel is nontoxic and bio degradable (Storage, high flash pt)
  • Production of bio diesel in India will reduce dependence on foreign suppliers, thus helpful in price stability.
  • Reduction of greenhouse gases at least by 3.3 kg COequivalent per kg of biodiesel.

Biofuels

Jatropha

Jatropha curcas is multi purpose non edible oil yielding perennial shrub. This is a hardy and drought tolerant crop can be raised in marginal lands with lesser input. The crop can be maintained for 30 years economically.

Sorghum

Sorghum (S. bicolor) is the most important millet crop occupying largest area among the cereals next to rice. It is mainly grown for its grain and fodder. Alternative uses of sorghum include commercial utilization of grain in food industry and utilization of stalk for the production of value-added products like ethanol, syrup and jaggery and bioenriched bagasse as a fodder and as a base material for cogeneration.

Pongamia

There is several non edible oil yielding trees that can be grown to produce biofuel. Karanja (Pongamia) is one of the most suitable trees. It is widely grown in various parts of the country.
Salient features of Pongamia
  • It is a Nitrogen fixing tree and hence enriches the soil fertility
  • It is generally not grazed by animals
  • It is tolerant to water logging, saline and alkaline soils,
  • It can withstand harsh climates (medium to high rainfall).
  • It can be planted on degraded, waste/fallow and cultivable lands
  • Pongamiaseeds contain 30-40% oil.
  • It helps in controlling soil erosion and binding sand dunes, because of its dense network of lateral roots.
  • Its root, bark, leaves, sap, and flower have medicinal properties. Dried leaves are used as an insect repellent in stored grains.
Properties of Pongamia Oil
  • Non edible oil is largely extracted from seeds.
  • The collected seeds consist of 95% kernel
  • The oil content varies between 27 - 40%.
  • When mechanical expellers are used for recovery of oil from the kernels, the yield of oil is reported to be about 24 to 26.5%
  • The crude oil is yellow orange to brown in color, which deepens on standing. It has a bitter taste, disagreeable odour, and it’s non-edible.
  • Apart from use as a biofuel, the oil can be used for lighting lamps, lubricant, water-paint binder, pesticide, and in soap making and tanning industries
  • The oil is known to be used for the treatment of rheumatism and human and animal skin diseases.
  • The press cake (left over after oil extraction) is rich in Nitrogen and hence can be used for improving soil fertility. The press cake when applied to the soil, also has pesticidal value, particularly against nematodes.
Pongamia seed oil Vs standard petroleum/diesel

  • Pongamia seed oil as a bio- fuel has physical properties very similar to conventional diesel.
  • It is, however a clean fuel (eco friendly) than conventional diesel

Geo-Thermal

Geo-Thermal

Geo-Thermal Energy
Geothermal Energy is heat stored in earth crust and being used for electric generation and also for direct heat application worldwide since beginning of last century. USA, Philippines, Indonesia, Mexico, Italy and Iceland are leading countries availing commercial exploitation with world production 12000 MW [1]. For harnessing Geothermal energy in the country the Ministry of New & Renewable Energy (MNRE) has been supporting R&D on exploration activities and Resource Assessment during last 25 years. This includes formation of expert groups, working group, core group and committees in addition to providing financial support for such projects and for resource assessment. MNRE is targeting for deployment of Geo-thermal capacity of 1000 MWth in the initial phase till 2022. Resource Assessment is being planned in 2016-2017 for public domain.  
The objective of the programme is to assess the potential of geothermal resources in the country and to harness these resources in two distinct categories namely
(i) Power Production
Government of India, Ministry of New and Renewable Energy (MNRE) contemplate major initiative in RDD&D of Geothermal technology for harnessing the geothermal energy in the country for the period 2015-17. Geothermal electricity generation is site and technology specific and India is in Low Geothermal Potential Region with low/medium heat enthalpy [12]. Government is planning to encourage the demonstration projects at the first stage to assess the technical viability of the project before going to the commercial models.
Various resource assessment carried out by GSI, UNDP and NGRI under aegis of CEA,UNDP & MNRE established the potential 10600 MWth /1000MWe spread over 340 hot springs across seven Geothermal provinces/11 states [2][14]. The average rough capital cost on not exceeding basis stands 30 Cr per MW (Rs 12 per KWhr) [18]. As per the international reports a 1 MW Geothermal Power Plant generates about 8.3 Millions Units (MU) per MW per annum [13] compared to Solar 1.6 MU per MW, Wind 1.9 MU per MW and Hydro 3.9 MU per MW

Ocean Energy 1. Introduction to Ocean Energy

Ocean Energy

1.    Introduction to Ocean Energy  
  
                 Oceans cover 70 percent of the earth’s surface and represent an enormous amount of energy in the form of wave, tidal, marine current and thermal gradient. The energy potential of our seas and oceans well exceeds our present energy needs. India has a long coastline with the estuaries and gulfs where tides are strong enough to move turbines for electrical power generation. A variety of different technologies are currently under development throughout the world to harness this energy in all its forms including waves (40,000 MW), tides (9000 MW) and thermal gradients (180,000 MW). Deployment is currently limited but the sector has the potential to grow, fuelling economic growth, reduction of carbon footprint and creating jobs not only along the coasts but also inland along its supply chains.  
 
            As Government of India steps up its effort to reach the objectives to contemplate its Renewable Energy and climate change objectives post 2022, it is opportune to explore all possible avenues to stimulate innovation, create economic growth and new jobs as well as to reduce our carbon footprint. Given the long-term energy need through this abundant source, action needs to be taken now on RDD&D front in order to ensure that the ocean energy sector can play a meaningful part in achieving our objectives in coming decades. MNRE looks over the horizon at a promising new technology and considers the various options available to support its development. Over 100 different ocean energy technologies are currently under development in more than 30 countries. Most types of technologies are currently at demonstration stage or the initial stage of commercialization.   
2.    Programme Objectives   
            The objective of the programme is to accelerate and enhance support for the research, development, resource assessment, testing and deployment of ocean energy in the country and to harness it for power generation and to overcome the barriers by encouraging collaboration between the technology developers, investors and other stakeholders so as to bridge the gap between research and the market. Resource Assessment is being planned in 2015-18 for public domain in association with IIT’s, NIOT and alike Government Research Institute to expedite the potential analysis and site identification in coordination with MNRE.  
3.    History    
  • Total identified potential of Tidal Energy is about 9000 MW in West Coast Gulf of Cambay (7000 MW), Gulf of Kutch (1200 MW) and in East Coast the Ganges Delta in the Sunderbans in West Bengal for small scale tidal power development estimates the potential in this region to be about 100 MW.
  • The total available potential of wave energy in India along the 6000 Km of India’s coast is estimated to be about 40,000 MW – these are preliminary estimates. This energy is however less intensive than what is available in more northern and southern latitudes.
  • In 2000 NIOT Goa, launched a programme to conduct study on technologies for producing high quality clean drinking water and energy from the ocean. The objective was to generate 2 - 3 lakh litres per day freshwater using the Low Temperature Thermal Desalination technology by 1 MW OTEC Power Plant. But it was dropped due to difficulties in installations.
  • In 2010 Kalpasar Tidal Power Project at The Gulf of Khambhat was identified as a promising site for tidal power generation by UNDP Expert.
  • In Jan 2011, the state of Gujarat announced plans to install Asia’s first commercial-scale tidal current power plant; the state government approved the construction of a 50 MW project in the Gulf of Kutch.
  • None at the moment, but India’s Ministry of New and Renewable Energy said in Feb 2011 that it may provide financial incentives for as much as 50 percent of the cost for projects seeking to demonstrate tidal power.
  • In 2014 Atlantis Energy proposed to install and develop 50-200 MW Tidal stream based power plant at Gulf of Chambey.
 4.    Technology             Although currently under-utilised, Ocean energy is mostly exploited by just a few technologies: Wave, Tidal, Current Energy and Ocean Thermal Energy.  
a)    Wave Energy   
            Wave energy is generated by the movement of a device either floating on the surface of the ocean or moored to the ocean floor. Many different techniques for converting wave energy to electric power have been studied. Wave conversion devices that float on the surface have joints hinged together that bend with the waves. This kinetic energy pumps fluid through turbines and creates electric power. Stationary wave energy conversion devices use pressure fluctuations produced in long tubes from the waves swelling up and down. This bobbing motion drives a turbine when critical pressure is reached. Other stationary platforms capture water from waves on their platforms. This water is allowed to runoff through narrow pipes that flow through a typical hydraulic turbine. Wave energy is proving to be the most commercially advanced of the ocean energy technologies with a number of companies competing for the lead.  
b)    Tidal Energy   
           The tidal cycle occurs every 12 hours due to the gravitational force of the moon. The difference in water height from low tide and high tide is potential energy. Similar to traditional hydropower generated from dams, tidal water can be captured in a barrage across an estuary during high tide and forced through a hydro-turbine during low tide. To capture sufficient power from the tidal energy potential, the height of high tide must be at least five meters (16 feet) greater than low tide. There are only approximately 20 locations on earth with tides this high and India is one of them. The Gulf of Cambay and the Gulf of Kutch in Gujarat on the west coast have the maximum tidal range of 11m and 8m with average tidal range of 6.77m and 5.23m respectively.  
   
c)     Current Energy   
Marine current is ocean water moving in one direction. This ocean current is known as the Gulf Stream. Tides also create currents that flow in two directions. Kinetic energy can be captured from the Gulf Stream and other tidal currents with submerged turbines that are very similar in appearance to miniature wind turbines. As with wind turbines, the constant movement of the marine current moves the rotor blades to generate electric power.  
   
d)      Ocean Thermal Energy Conversion (OTEC)   
            Ocean thermal energy conversion, or OTEC, uses ocean temperature differences from the surface to depths lower than 1,000 meters, to extract energy. A temperature difference of only 20°C can yield usable energy. Research focuses on two types of OTEC technologies to extract thermal energy and convert it to electric power: closed cycle and open cycle. In the closed cycle method, a working fluid, such as ammonia, is pumped through a heat exchanger and vaporized. This vaporized steam runs a turbine. The cold water found at the depths of the ocean condenses the vapor back to a fluid where it returns to the heat exchanger. In the open cycle system, the warm surface water is pressurized in a vacuum chamber and converted to steam to run the turbine. The steam is then condensed using cold ocean water from lower depths. OTEC has a potential installed capacity of 180,000 MW in India.  
    

BIOMASS POWER AND COGENERATION PROGRAMME

BIOMASS POWER AND COGENERATION PROGRAMME

1. INTRODUCTION

Biomass has always been an important energy source for the country considering the benefits it offers. It is renewable, widely available, carbon-neutral and has the potential to provide significant employment in the rural areas. Biomass is also capable of providing firm energy. About 32% of the total primary energy use in the country is still derived from biomass and more than 70% of the country’s population depends upon it for its energy needs. Ministry of New and Renewable Energy has realised the potential and role of biomass energy in the Indian context and hence has initiated a number of programmes for promotion of efficient technologies for its use in various sectors of the economy to ensure derivation of maximum benefits Biomass power generation in India is an industry that attracts investments of over Rs.600 crores every year, generating more than 5000 million units of electricity and yearly employment of more than 10 million man-days in the rural areas. For efficient utilization of biomass, bagasse based cogeneration in sugar mills and biomass power generation have been taken up under biomass power and cogeneration programme.

Biomass power & cogeneration programme is implemented with the main objective of promoting technologies for optimum use of country’s biomass resources for grid power generation. Biomass materials used for power generation include bagasse, rice husk, straw, cotton stalk, coconut shells, soya husk, de-oiled cakes, coffee waste, jute wastes, groundnut shells, saw dust etc.

2. POTENTIAL

The current availability of biomass in India is estimated at about 500 millions metric tones per year. Studies sponsored by the Ministry has estimated surplus biomass availability at about 120 – 150 million metric tones per annum covering agricultural and forestry residues corresponding to a potential of about 18,000 MW. This apart, about 7000 MW additional power could be generated through bagasse based cogeneration in the country’s 550 Sugar mills, if these sugar mills were to adopt technically and economically optimal levels of cogeneration for extracting power from the bagasse produced by them

3. TECHNOLOGY

3.1 Combustion

The thermo chemical processes for conversion of biomass to useful products involve combustion, gasification or pyrolysis. The most commonly used route is combustion. The advantage is that the technology used is similar to that of a thermal plant based on coal, except for the boiler. The cycle used is the conventional ranking cycle with biomass being burnt in high pressure boiler to generate steam and operating a turbine with generated steam. The net power cycle efficiencies that can be achieved are about 23-25%. The exhaust of the steam turbine can either be fully condensed to produce power, or used partly or fully for another useful heating activity. The latter mode is called cogeneration. In India, cogeneration route finds application mainly in industries.\
Sugar industry has been traditionally practicing cogeneration by using bagasse as a fuel. With the advancement in the technology for generation and utilization of steam at high temperature and pressure, sugar industry can produce electricity and steam for their own requirements. It can also produce significant surplus electricity for sale to the grid using same quantity of bagasse. For example, if steam generation temperature/pressure is raised from 400oC/33 bar to 485oC/66 bar, more than 80 KWh of additional electricity can be produced for each ton of cane crushed. The sale of surplus power generated through optimum cogeneration would help a sugar mill to improve its viability, apart from adding to the power generation capacity of the country.



4. DEPLOYMENT

The Ministry has been implementing biomass power/co-generation programme since mid nineties. A total of approximately 500 biomass power and cogeneration projects aggregating to 4760 MW capacity have been installed in the country for feeding power to the grid. In addition, around 30 biomass power projects aggregating to about 350 MW are under various stages of implementation. Around 70 Cogeneration projects are under implementation with surplus capacity aggregating to 800 MW. States which have taken leadership position in implementation of bagasse cogeneration projects are Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra and Uttar Pradesh. The leading States for biomass power projects are Andhra Pradesh, Chattisgarh, Maharashtra, Madhya Pradesh, Gujarat and Tamil Nadu.
