What is the contribution of natural gas as fuel for Power generation in India? (10 marks)
Consumption of Electricity:
The estimated electricity consumption increased from 43,724 GWh during 1970-71 to 6,94,392 GWh during 2010-11, showing a CAGR of 6.98% (Table 6.9). The increase in electricity consumption is 13.34% from 2009-10 (6,12,645 GWh) to 2010-11 (6,94,392 GWh). Of the total electricity sales in 2010-11, industry sector accounted for the largest share (38.6%), followed by domestic (23.8%), agriculture (19.6%) and commercial sector (9.89%). However, it is seen that electricity consumption in domestic sector and agriculture sector has increased at a much faster pace compared to other sectors during 1970-71 to 2010-11, with CAGRs of 9.67% and 8.61% respectively.
Power generation in India:
According to the MoPNG, gas use in India amounted to 59 bcm in FY 2009/10, up from 43 bcm in FY 2008/09; energy use amounted to 61% compared to 39% used for non-energy purposes. Before the start of Krishna-Godavari in April 2009, consumption was supply constrained and demand for gas could easily have been 30 bcm higher. Indeed, it is important to make a clear distinction between potential demand and actual consumption as these numbers widely differ. In 2007, unmet demand was estimated at 35 bcm.18 Demand has been constrained by the lack of supply as domestic production and LNG imports, even at the recent higher supply rates, were insufficient to meet potential demand. The IEA presented two longterm scenarios in the WEO issued in November 2009: a Reference Scenario and a 450 Scenario.
The first scenario can be described as business-as-usual, while the second tries to limit the global temperature increase to 2°C. In its Reference Scenario, the IEA expects Indian gas demand to increase to 94 bcm by 2020 and to 132 bcm by 2030, driven by the industrial and power generation
