Electricity / Power in India

Overview
  • India has an installed power generation capacity of 155,000 MW
  • The total demand for power is expected to cross 950,000MWby 2030 
  • The government plans to add about 78,000 MWof installed generation capacity by 2012 
  • Main sources of power in India include thermal power, hydro power and nuclear power 
  • Private sector contributes around 13.5% to total power generation 
  • The per capita power consumption in India is 612 kWh
  • Only 44% of rural households have access to electricity 
  • The Government of India is working towards the objective of ‘Power for All by 2012
Power transmission

  • Transmission of electricity is defined as bulk transfer of power over a long distance at a high voltage, usually 132 kV or more
  • Transmission in the country is divided into five regional transmission system:
Northern region (HQ Delhi): largest in area
Norther eastern region (Shillong) : Highest hydro:thermal power ratio (1:1)
Eastern region (HQ Bangalore)
Southern region (HQ Bangalore)
Western region (HQ : Nagpur)

  • The interconnected transmission system within each region is called the Regional Grid. The eastablishment of a National Grid has been planned
  • Power transmission is handled by the Power Grid Corporation of India Ltd. (PGCIL)
  • Four of the five Regional Grids now operate as a synchronous grid (western, northern, eastern and norther eastern). The Southern Grid is connected to the sysnchronous grid separately through HVDC links.
  • Each Regional Grid functions under a Regional Load Despatch Cenre. Additionally, a National Load Despatch Cenre has been established in New Delhi to coordinate efforts to establish the National Grid
Power distribution

  • Transmission and distribution (T&D) losses in India reach 33%
  • Losses include technical losses such as unplanned lines, overloading, and commercial losses such as theft, pilferage etc
  • The Accelerated Power Development and Reform Programme (APDRP) was initiated in 2001 to bring down T&D Losses below 15%
  • Power distribtion is the responsibility of State Electricity Boards (SEBs)
  • The Maharashtra State Electricity Board (MSEB) is the second largest power generating utility in India, after the National Thermal Power Corporation (NTPC)

  • The PGCIL operates five Regional Grids (see above). It is also working towards establishing a National Grid in India
Rural Electrification Corporation Ltd (REC)
  • The Rural Electrification Corporation aims to finance and promote rural electrification projects in the country
  • It was established in 1969 and is headquartered in New Delhi
  • The REC provides loans to SEBs and state power utilities for investment in rural electrificaiton schemes
  • The REC is the nodal agency for the implantation of the RGGVY

National Electricity Policy

  • Launched in 2005
  • The objectives of the Policy include
    • Provide access to electricity to all housholds by 2010
    • Power demand to be fully met by 2012. Energy and peaking shortages to be overcome
    • Supply of reliable and quality power at affordable rates
    • Minimum lifeline consumption of 1 unit per houshold per day by 2012
    • Per capita availability of electricity to be increased to over 1000 units by 2012
    • Financial turaround and commercial viability of electricity sector
    • Protection of consumer’s interests
  • The Policy also required the Central Electricity Authority (CEA) to frame a National Electricity Plan every five years, which covered
  • The Policy seeks to address multiple issues including the following
    • Rural electrification
    • Power generation, transmission and distribution
    • Recovery of cost and subsidies
    • Technology development and R&D
    • Power sector reforms including private sector participation
    • Energy conservation
    • Renewable energy sources
  • In order to implemtn the policy, the RGGVY scheme was launched by the Rural Electrification Corporation

Rural Electrification Policy

  • Launched in 2006
  • Objectives include
    • Provision of access to electricity to all housholds by 2009
    • Quality and realible power supply at reasobable rates
    • Minimumhousehold consumption of 1 unit per household per day by 2012
  • As per the policy, all state government were required to prepare and notify a Rural Electrification
    Plan to achieve the Policy goals

Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY)

  • Thr RGGVY was launched in 2005 to implement the National Electricity Policy
  • The RGGVY is implemented by the REC
  • The RGGVY provides 90% Union Government subsidy for rural electrification projects including
    • Rural Electricy Distribution Backbone (REDB): The REDB is to act as the primary infrastructure for the distribution of electricity in rural areas. Each Block to have at least one 33/11 kV substation
    • Village Electrification Infrastructure (VEI): at least one distribution transformer in each village
    • Decentralised Distributed Generation (DDG) System: these systems are to act as stand-alone power generation and distribution mechanismwhere supply from the grtid is not possible or not cost-effective
  • The RGGVY provides for free connection to all households below the poverty line
  • The Scheme says that there shall be no discrimination in the hours of supply between urban and rural areas. This should help in development of rural industries, health care and education facilities
  • The Scheme targets the electrification of 125,000 un-electrified villages

    National mission on monsoon prediction soon

    • The Union Cabinet is likely to give its final approval for a national mission to try and improve the accuracy of monsoon forecasts by this month-end.
    • The mission, estimated to cost Rs. 350 crore, is designed to improve the current generation of dynamic numerical models for prediction through better insight of the highly complex phenomenon of monsoon.
    • Under the project, scientists would work on models from the United Kingdom's Met Office and the United States' National Centers for Environment Prediction . 
    • The mission would have two components relating to two different timescales — monthly, seasonal and intra-seasonal scale on the one hand and a medium range forecast, up to 15 days, on the other.
    • At present, India Meteorological Department makes its forecasts based on the system of a statistical model, which makes the prediction on the basis of several predictors. 
    • India does not have a dynamic numerical model of it own. The goal now is to develop a model that would be India-specific within five years

    West Bengal to be renamed Paschimbanga

    • A consensus to rename West Bengal as Paschimbanga was on Friday reached at an all-party meeting to change the nomenclature of the state.
    • The choice was made from among the suggestions of 'Paschimbanga', 'Bangla' and 'Bangabhumi'
    • Once the bill in this regard is passed by two-thirds majority in both Lok Sabha and Rajya Sabha and ratified by the President, the state would get the new name.
    • In the past also, similar moves were taken to rename West Bengal -- once in 1974 during Congress rule and later in 1999 when Left Front was in power. The moves did not mature due to various reasons

    Ports in India

    The classification of Indian ports into major, minor and intermediate has an administrative significance. Indian government has a federal structure, and according to its constitution, maritime transport falls under the "concurrent list", to be administered by both the Central and the State governments. While the Central Shipping Ministry administer the major ports, the minor and intermediate ports are administered by the relevant departments or ministries in the nine coastal states—West Bengal, Orissa, Andhra Pradesh, Tamil Nadu, Kerala,Karnataka, Goa, Maharashtra and Gujarat. Several of these 185 minor and intermediate ports are merely "notified"; little or no cargo handling actually takes place. These ports have been identified by the respective governments to be developed, in a phased manner, a good proportion of them involving public–private partnership.

    Major ports as below

    PORTS                       Location
    KOLKATA              Bengal
