Energy Development

  Energy is an essential input for economic development and improving the quality of life. Development of conventional forms of energy for meeting the growing needs of society at a reasonable cost is the responsibility of the Government Development and promotion of non-conventional /alternative/ new and renewable sources of energy such as solar, wind and bio energy etc are getting sustained attention. Nuclear energy development being geared up to contribute significantly to the overall energy availability in the country.

 

Kerala’s Power Sector Projections

          In the past, the energy demand was presumed to be basis with load factor being used to convert the projected energy demand to peak MW demand. The projected energy demand was worked out by a combination of end use and time series analysis. This was the methodology used in the Electric Power Surveys (EPS) conducted by CEA in conjunction with the State Electricity Boards. One of the problems with the above approach has been the consistent over projection of peak demand. The annual growth of peak power demand has been assumed to be of the order of 7-8% and this has resulted in projections well beyond actual demands realised. Some of these anomalies have been corrected in the current EPS conducted and the projections for Kerala as continued in the 17th Draft EPS. The figures for Kerala in terms of demand projection in the Draft 17th EPS is given here.              

  

          As can be seen from 17th EPS Draft Report, there are a number of assumptions, which may result in the actual demand being more than what is being projected in the EPS or being less. KSEB’s own projections taking into account a higher growth rate and a slightly lower load factor projects the following demands for the 11th plan period is given here.            

  

                  The Peak load and Energy Requirement projected in the 18th EPS and its variations with actual is shown below. From this, it can be seen that Maximum Demand and Energy Requirement of the State has not reached to the figures projected in the 18th EPS and there is considerable variations when compared to the realized actual figures.

           As per the 19th Electric Power Survey conducted by Central Electrical Authority, the projected energy consumption for the next 10 years for Kerala is 25,480 mu (million units, 1 unit=1 kwh) in 2017-18, 29,924 mu in 2020-21, 34,393 mu in 2023-24 and 38,756 mu in 2026-27. Over 10 years therefore Kerala's energy is estimated by this survey to increase by approximately 52 per cent above current consumption.

 

Power Sector in India

 

             In India, electricity from thermal energy is the predominant source of power. It constitutes nearly 67 percent of the total installed capacity of the country as on August 31, 2017. Contribution of electricity generation from different sources to the national grid, and the comparison to the previous years is given below. As per this, the total installed capacity for power generation in India is 3,29,226 MW. Of late, renewable sources have emerged as the second largest electricity source in the country leaving hydro to the third position.
