Electricity regulation in India: overview

India is the world's third largest producer and third largest consumer of electricity. During the fiscal year FY , the gross electricity generated by utilities in India was 1, India has a surplus power generation capacity but lacks adequate distribution infrastructure. To address this, the Government of India launched a program called "Power for All" in India's electricity sector is dominated by fossil fuels, in particular coal, which during the fiscal year produced about three-quarters of the country's electricity.

The government is making efforts to increase investment in renewable energy. The government's National Electricity Plan of states that the country does not need more non-renewable power plants in the utility sector until , with the commissioning of 50, MW coal-based power plants under construction and addition of , MW total renewable power capacity after the retirement of nearly 48, MW old coal-fired plants.

The first demonstration of electric light in Calcutta now Kolkata was conducted on 24 July by P. A month later, the company was renamed the Calcutta Electric Supply Corporation. The control of the company was transferred from London to Calcutta only in The introduction of electricity in Calcutta was a success, and power was next introduced in Bombay now Mumbai.

The first hydroelectric installation in India was installed near a tea estate at Sidrapong for the Darjeeling Municipality in India began using grid management on a regional basis in the s. These regional links were established to enable transmission of surplus electricity between states in each region. In the s, the Indian government began planning for a national grid.

Regional grids were initially interconnected by asynchronous high-voltage direct current HVDC back-to-back links facilitating the limited exchange of regulated power. The links were subsequently upgraded to high capacity synchronous links. The first interconnection of regional grids was established in October when the North Eastern and Eastern grids were interconnected. The Western Grid was interconnected with these grids in March The Northern grid was also interconnected in August , forming a Central Grid that was synchronously connected and operating at one frequency.

By the end of the calendar year , despite poor hydroelectricity generation, India had become a power surplus nation with huge power generation capacity idling for want of demand. India exported 5, GWh to neighbouring countries, against a total import of 5, GWh. The total installed power generation capacity is the sum of utility capacity, captive power capacity, and other non-utilities. The total installed utility power generation capacity as on 30 November by sector and type is given below.

The break up of renewable energy sources RES is:. The installed captive power generation capacity above 1 MW capacity associated with industry-owned plants is 78, MW as of 31 March , In fiscal year , GWh was generated. This is a list of states and territories of India by installed power generation capacity.

During the fiscal year , the utility energy availability was 1, Peak load met was , MW, 1, MW Nearly 0. The technologies and fuel sources India adopts as it adds this electricity generation capacity may have a significant impact on global resource usage and environmental issues.

The growth of the electricity sector in India may help find a sustainable alternative to traditional fuel burning.

In addition to air pollution problems, a study finds that discharge of untreated sewage is the single most important cause for pollution of surface and groundwater in India. The majority of government-owned sewage treatment plants remain closed most of the time in part because of the lack of a reliable electricity supply to operate the plants.

Uncollected waste accumulates in urban areas, causing unhygienic conditions, and release heavy metals and pollutants that leaches to surface and groundwater. Other drivers for India's electricity sector are its rapidly growing economy, rising exports, improving infrastructure and increasing household incomes.

The per capita annual domestic electricity consumption in India during the year was 96 kWh in rural areas and kWh in urban areas for those with access to electricity. Globally the per capita annual average is 2, kWh and in the European Union it is 6, kWh. The programme focused on reforms in the rural power sector by separating feeder lines for rural households from those for agricultural applications, and strengthening transmission and distribution infrastructure.

As of 4 January , India has recorded rapid growth in electricity generation since , increasing from TW-hr in to 1, TW-hr in The gross utility electricity generation excluding imports from Bhutan was 1, billion kWh in , representing 1.

In the year , all the incremental electricity generation is contributed by renewable energy sources as the power generation from fossil fuels decreased. Estimated value. For utility power generation, India consumed However coal imports for utility power generation increased by The Centre for Science and Environment has assessed the Indian coal-based power sector as one of the most resource-wasteful and polluting sectors in the world, in part due to the high ash content in India's coal.

The coal ash reduction industry has grown rapidly in India, with current capacity topping 90 megatonnes. Before a thermal power plant is approved for construction and commissioning in India it must undergo an extensive review process that includes environmental impact assessment. The state and central power generation companies are permitted by the Government of India to minimize the cost of coal transportation using flexible coal linkage swaps from inefficient plants to efficient plants, and from plants situated far from coal mines to plants close to the pit head, leading to a reduction in the cost of power.

India's coal-fired, oil-fired and natural gas-fired thermal power plants are inefficient and replacing them with cheaper renewable technologies offers significant potential for greenhouse gas CO 2 emission reduction. Some diesel generator plants and gas turbine plants were also decommissioned in India has committed to install , MW renewable energy capacity by Also ramping up, ramping down, warm start up, hot start up capabilities of existing coal based power stations are critical to accommodate the frequent variations in renewable power generation.

The installed capacity of natural gas-based power plants including the plants ready to be commissioned with the commencement of natural gas supply was nearly 26, MW at the end of the financial year Many power stations were shut down throughout the year for lack of natural gas supply.

The natural gas shortage for power sector alone was nearly million cubic metre per day at standard conditions. Gasification of coal or lignite or pet coke or biomass produces synthetic natural gas or syngas also known as coal gas or wood gas which is a mixture of hydrogen, carbon monoxide and carbon dioxide gases.

Coal gas can also be produced by underground coal gasification if the coal deposits are located deep in the ground or it is uneconomical to mine the coal. As of 31 March , India's grid-connected electricity generation capacity is about Bids have been invited for installation of a further GW, to achieve a total of GW total installed capacity of non-conventional renewable power by 31 March The hydro-electric power plants at Darjeeling and Shivanasamudram were among the first in Asia, and were established in and respectively.

The estimated amount of viable hydro power varies with improved technology and the cost of electricity generation from other sources. In addition, there is an estimated 6, MW of potential for small, mini, and micro-hydro generators, and 56 sites for pumped storage schemes with an aggregate installed capacity of 94, MW have been identified.

The installed hydro power capacity as of 31 March was approximately 45, MW, Pumped storage schemes offer the potential for centralized peak power stations for load management in the electricity grid.

Storing electricity by alternative systems such as batteries , compressed air storage systems, etc. India has already established nearly 4, MW pumped storage capacity as part of its installed hydro power plants.

The solar energy sector in India offers potentially enormous capacity, though little of this potential has so far been exploited.

Solar radiation of about 5, trillion kWh per year is incident over India's land mass, with average daily solar power potential of 0. Solar power plants require nearly 2. Solar plants with 1. These are potentially suitable for solar power. Land acquisition is a challenge for solar farm projects in India. Some state governments are exploring innovative ways to address land availability, for example, by deploying solar capacity above irrigation canals.

It was the first such project in India. A major disadvantage of solar power is that it produces electricity only in daylight, and not during night time or cloudy daytime. This disadvantage can be overcome by installing grid storage, such as pumped-storage hydroelectricity.

Most of the groundwater pumping power required can be met directly by solar power during the day time. They can respond to demand round the clock, and work as base load power plants when there is excess solar energy. A mix of solar thermal and solar photovoltaic plants offers the potential to match load fluctuations without requiring costly battery storage. India has the fourth largest installed wind power capacity in the world. The development of wind power in India began in the s in Tamil Nadu and significantly increased in the last decade.

As of 31 March , the installed capacity of wind power was In , wind power accounted for 8. India aims to install a total 60 GW of wind power capacity by Biomass is organic matter from living organisms.

As a renewable energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel using a range of methods which are broadly classified into thermal, chemical, and biochemical methods. Biomass, bagasse , forestry, domestic organic wastes, industrial organic wastes, organic residue from biogas plants, and agricultural residue and waste can all be used as fuel to produce electricity.

The total use of biomass to produce heat in India was nearly Mtoe in This traditional use of biomass is being replaced by liquid petroleum gas in rural areas, resulting in increased burning of biomass in fields, This has become a major source of air pollution in nearby towns and cities. Large quantities of imported coal are being used in pulverised coal-fired power stations. Raw biomass cannot be used directly in the pulverised coal mills as it is difficult to grind into fine powder due to caking.

However, torrefaction makes it possible for biomass to replace coal. In , India started a new initiative to demonstrate the utility of medium-size mixed feed biogas -fertiliser pilot plants.

The government approved 21 projects with an aggregate capacity of 37, cubic metres per day, of which 2 projects were successfully commissioned by December Biogas is primarily methane, and can also be used to generate protein rich feed for cattle, poultry and fish by growing Methylococcus capsulatus , a bacterium that grows directly on methane.

This can be done economically in villages with low requirements for land and water. The government is exploring several ways to use agro waste or biomass in rural areas to improve the rural economy.

Transmission and distribution refers to the different stages of carrying electricity over poles and wires from generators to a home or a business. The primary distinction between the two is the voltage level at which electricity moves in each stage. After electricity has been generated, a system of electrical wires carries the electricity from the source of generation to our homes and businesses.

A renewable electricity generation technology harnesses a naturally existing energy flux, such as wind, sun, heat, or tides, and converts that flux to electricity. Natural phenomena have varying time constants, cycles, and energy densities. To tap these sources of energy, renewable electricity generation technologies must be located where the natural energy flux occurs, unlike conventional fossil-fuel and nuclear electricity-generating facilities, which can be located at some distance from their fuel sources. Renewable technologies also follow a paradigm somewhat different from conventional energy sources in that renewable energy can be thought of as manufactured energy, with the largest proportion of costs, external energy, and material inputs occurring during the manufacturing process.

Abstract The Indian power sector value chain can be broadly segmented into generation, transmission, and distribution sectors. At an all-India level, the total installed generation capacity was 3,56, The peak load demand of 1,75, MW during FY was largely met, considering that the peak load supply shortfall was MW 0. In the next five years, the Central Electricity Authority CEA estimates that existing generation capacity, augmented by power projects to be commissioned during this period, will be adequate to meet the energy demand growth.
