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.
Universal access to affordable power in a sustainable manner is the guiding principle for the Power sector. Sources of power in India range from conventional sources to viable non-conventional sources. Almost 80 per cent of India’s energy requirements are met by coal, oil, natural gas and solid biomass (Source: International Energy Agency). India’s per capita emission is quite low but in absolute terms, it is the 3rd largest greenhouse gas emitter (country-wise) in the world. Per Capita Electricity Consumption of India in general and Kerala in particular is much below the world average.
India’s power sources range from traditional ones to sustainable unconventional origins. Over 80 per cent of India’s energy demands are fulfilled by three fuels: coal, oil, and solid biomass (Source: International Energy Agency 2021). The remarkable growth of solar and wind energy capacity of the country has enabled it to maintain its position as a global leader in renewable energy adoption. Today, India stands 4th globally in Renewable Energy Installed Capacity, with 43 per cent (as on September 30, 2023) of its total installed electricity capacity coming from nonfossil energy sources. (Source: Ministry of New and Renewable Energy (MNRE), GoI). India ranks 67th in the World Economic Forum energy transition index, which evaluates 120 economies’ energy systems. This index is developed by considering the three energy triangle imperatives-equity, security, and sustainability - while effectively utilizing energy transition enablers.

Power Sector - Indian Scenario
The national grid has an installed capacity of 4,24,288 MW as on August 31, 2023. In India, electricity from thermal energy is the dominant source of power. It constitutes nearly 56.19 per cent of the total installed capacity in the country. Contribution of electricity generation from different sources to the national grid. Of late, renewable sources have emerged as the second largest electricity source in the country, relegating hydroelectric power to the third position.

Power Sector in Kerala
Kerala is among the Front Runner States in the State Energy Efficiency Index published by Bureau of Energy Efficiency, Ministry of Power, Government of India. Though highly dependent on imported power, the State could provide power for all on demand, without imposing on restrictions such as load shedding or power cut. Power development activities in the State are carried out mainly through four agencies, namely, Kerala State Electricity Board Limited (KSEBL), Agency for Non-conventional Energy and Rural Technology (ANERT), Electrical Inspectorate, and Energy Management Centre (EMC).The Table below shows the details growth of the power system in the State for the last five years.
