Energy demand by Sector. Energy demand by Fuel.
• To produce 1 Unit of electricity, we release 1 kg of CO2.
• India responsible for 700 million metric tons of CO2.
• We are 3th largest contributor to the world pollution.
• India accounts for 5.3% of greenhouse emission.
Power Sector
• 616 kWh electricity use/capita/year
• Plant load factor = Actual generation / Max possible generation (rated load)
• Plant Heat Rate = Heat input / Electricity output
• Net Power = Gross – Auxiliary Consumption
• Installed capacity 249488.31(As on 30-06-2014)MW
• Electricity production = 762.67 billion kWh during April’12 January’13

Biomass Estimation
• 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.
• Uncertainties in estimation
• Usage- Domestic, Brick klin, Rice mills, and other industries
• Per capita biomass use approx constant over last 20 years
• 6.4 GJ/capita/year
• 6180 PJ – 1997-98 (4% of world)
• population 17.1% of world population
Electricity
• 214.6 GW Installed Capacity as on 28-02-13 (about 4.1% of
World Capacity Average 0.177 kW of installed capacity/capita
• World Installed capacity 0.73 kW/capita
• Low Electricity Consumption –India about 818 kWh/capita/yr
as on 2011
• Nepal 93, Bangladesh 279 kWh/capita/yr as on 2008
• World Average Electricity Consumption- 2894 kWh/capita/yr
• Electricity production as on 2008 is 20,261 billion kWh
Electricity Characteristics
• High Losses - T&D and Theft 24% in most SEBs
• As many as 559241 villages out of 593732 (about 94.2%)
Villages has been electrified in India as on 31-01-2013
• Electricity Sector – from State Controlled Monopoly –
Transition – to Regulated Sector with Privatization
• Subsidized electricity to agriculture sector,
low usage residential
Electricity Sector
• SEB annual loss by 31 march 2011 is Rs 68,000crores
• Gap of 92 p/kWh- between cost of supply and revenue
• Peak shortage 12.9%, energy shortage 10.3%
• Estimated requirements of 400,000 MW additional
capacity by 2032
• 70% increase in greenhouse gas emissions from 1970 to 2004 (2004 at 49 GtCO2 equivalent)
• Automotive (120%) & Energy (145%) sectors main contributors
• Energy efficiency, adopting cleaner fuels & renewable energy key levers for mitigation Source: Report of Intergovernmental

Global Power Sector
Global GDP projected to grow at 3.4% annually till 2030
Emerging economies like China and India projected to grow by 8 – 10%
Developed economies currently take lion’s share in energy consumption
A fourth of the world’s population lives in darkness
Increase in net electricity consumption by 2015: 42%
New generation capacity required by 2030: 1,600 GW (5,087 GW including replacement capacity)
Twin threats: Inadequate and insecure supply of
energy sources Environmental harm due to over-
consumption of polluting fuels
Strong Correlation between per Capita GDP and per Capita Electricity Consumption.
Forecasts Point Towards a Robust GDP Growth over the next 3 to 5 decades.

Country’s Energy Scenario – A Quick Recap
Acute shortage of Power at
present.
Energy Shortage was 10.3%
Peak Shortage was 12.9%
Power Generation Capacity
addition is far below the
expected (only 54000 MW
against expected 62000 MW
during 2007 – 2012)
We need to urgently ensure power availability to sustain our GDP growth.
