This paper is prepared on the answer to the valuable comments made by late Jeewan P. Thanju on my article ‘Water Resources of Nepal: Misconception and Reality’ published in The Rising Nepal on January 23 & 24, 2014.The rivers of Nepal possess sufficient hydropower potentiality to enhance the country’s socio-economic development. However, some spurious expert and vested interest group exaggerated the hydro potentiality and distorted the fact of water resources development prospective in Nepal. This has created confusion among the policymakers, politician and multilateral agencies. As a result, hydropower development in Nepal has headed for wrong course, and now the power sector, the vital impetus for socio-economic development is in dire strait. This paper highlights the uniqueness and distinct technical features of Nepalese Power Sector. In this paper important component like Integrated National Power System/Grid (INPS), Power Generation Modality (Hydropower, Thermal/Nuclear Plants and Diesel Plants) are well described and Master Plan, Project Selection, Construction Schedules and Hydropower potentiality of Nepal are discussed in detail. In a severe power and energy crisis situation in the country, power export is not recommended. Nepal needs 3000 MW to reach the level of other south Asian nations. INPS is owned and operated by NEA; therefore NEA also has the responsibility to prepare master plan for power generation, transmission and distribution. But, the Department Electricity Development a regulatory body of Ministry of Energy of is undertaking / carrying out feasibility study without taking care of INPS/country’s power requirement. This has created duplication of work and confusion; as such the Ministry of Energy deviated from its responsibility of preparing sound policy, regulation and monitoring them strictly. The Ministry shouldn’t indulge in feasibility study, construction and operational activities, which come under the responsibility of concerned technical department /authority.

The largest percentage of China’s total coal consumption is used for coal-fired power generation, which has resulted in the power sector becoming China’s largest carbon emissions emitter. Most of the previous studies concerning the driving factors of carbon emissions changes lacked considerations of different socioeconomic factors. This study examines the impacts of eight factors from different aspects on carbon emissions within power sector from 1981 to 2013 by using the extended Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model; in addition, the regression coefficients are effectively determined by a partial least squares regression (PLS) method. The empirical results show that (1) the degree of influence of various factors from strong to weak is urbanization level (UL) > technology level (T1) > population (P) > GDP per capita (A) > line loss (T2) > power generation structure (T3) > energy intensity (T4) > industry structure (IS); (2) economic activity is no longer the most important contributing factor; the strong correlation between electricity consumption and economic growth is weakening; and (3) the coal consumption rate of power generation had the most obvious inhibitory effect, indicating that technological progress is still a vital means of achieving emissions reductions.

The Way

China's electrical power industry has been undergoing piecemeal reforms over the last 15 years. Some of these reforms, such as substantial tariff increases, have been deliberate and have been implemented directly by government. Other changes, such as the increased variety of investors, including foreign investors, have been more spontaneous and have resulted in a gradual evolution in the way the industry works. In 1996 the Chinese government announced a more radical package of reform starting with the new Electricity Law which laid the foundations for a degree of competition in power generation, but without wholesale privatization.

Power is the basic key for growth of any country’s economy. The increased demand of electricity, need to optimize the utilization of power generation capacity and increase in the interconnections are the major issues with which power sector is dealing with. Energy consumption per person is also rising tremendously in developing countries. However, installing a new power plant cannot be a solution every time. Dense population, availability of land, initial and installation cost can be the major issues in this case. Huge transfer of power from generating plants to load centre at long distance with bulky transmission lines is causing to upgrade voltage class to Extra High Voltage (EHV) from High Voltage (HV).

Reducing Co2 Emission

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper IPTC 21348, “The Color of Energy: The Competition To Be the Energy of the Future,” by Hon Chung Lau, National University of Singapore, prepared for the 2021 International Petroleum Technology Conference, held virtually 23 March–1 April. The paper has not been peer reviewed. Copyright 2021 International Petroleum Technology Conference. Reproduced by permission. The author of the complete paper, for the purposes of this study, characterizes energies as brown, blue, or green. Brown energies are carbon dioxide (CO2)-emitting fossil fuels, such as gas, oil, or coal. Blue energies use carbon capture and storage (CCUS) technologies to remove the emitted CO2 from brown energies. Green energies are zero- or low-CO2-emitting renewable energies. By analyzing the CO2 intensity and levelized cost of energy of energy carriers of different colors, the author shows that renewable energies are best used in replacing fossil fuels in the power sector, where they have the greatest effect in reducing CO2 emission. Overview By 2017, only 11% of the world’s final consumption came from renewable energies, 85% came from fossil fuel, and 4% came from nuclear energy. Energy consumption can be divided into three sectors: power, transport, and thermal. At the time of writing, 26.4% of global power (electricity) consumption comes from renewable energies. In this sphere, renewable energies are making the most significant contribution in reducing CO2 emission. Forty-one percent of CO2 emission comes from electricity and heat, 21% from transport, and 21% from industry. Consequently, the key to global decarbonization is to decarbonize these three sectors. Green Energy Is Preferred Green energies consist of six major types: solar photovoltaic, solar thermal, wind, hydroelectricity, geothermal, and biomass. If 1 kWh of electricity generated by renewable energy (with the exception of biomass) is used to replace 1 kWh of electricity generated by fossil fuel, the net CO2 savings will amount to 0.8, 0.6, and 0.4 kg for replacing coal, oil, and natural gas, respectively. However, if 1 kWh of renewable electricity is used to generate green hydrogen (H2), which is then used for heat generation in industry, it will yield roughly 0.8 kWh of thermal energy, which replaces the same amount of thermal energy by natural gas. This amounts to a CO2 savings of only 0.16 kg CO2/kWh. Consequently, renewable power has the highest CO2 savings effect if it is used to replace fossil fuel for power generation rather than to replace fossil fuel for heat generation. Decarbonizing the Power Sector The power sector is easiest to decarbonize. The three methods foreseen to decarbonize the power sector are nuclear power, blue electricity generated by fossil-fuel power plants equipped with CCUS, and green electricity produced by renewables. The use of nuclear power plants is a country-specific issue. The dual challenge of nuclear plant safety and nuclear waste storage is a key sustainability issue. Recently, interest has been renewed in the idea of increasing investment in nuclear energy for decarbonizing the power sector. It is noteworthy that the countries for whom more than a quarter of their power generation is provided by nuclear energy are all in Europe.
