Contradictions in electric power sector development: Ukraine versus EU

Ukraine strives to be a full member of the EU and competitive in its market space, including energy markets. However, the UA electric power sector lags behind the EU common one. To prove this input-output model of electricity flows was constructed, Sankey diagrams were built, and qualitative indicators were determined. Based on the Eurostat dataset we found contradictions in Ukrainian electric power sector development against the European common one from 1991 to 2020. Mainstream trends in EU electric power sector development are decarbonization, development of highly efficient cogeneration, increasing energy efficiency at all stages, decentralization, increasing energy dependency, and all-round electricity penetration. At the same time, key tendencies in the UA electric power sector development were: gas-coal switching, reducing quality and quantity of cogeneration, stable too-low energy efficiency, centralization, isolation and self-sufficiency, and deindustrialization. Comprehending these contradictions determines the way for achieving sustainability in the UA electric power sector after the war.

Optimizing future electric power sector considering water-carbon policies in the water-scarce North China Grid

The North China Grid has the highest proportion of fossil fuel-based electricity generation in China and also suffers from severe water scarcity issues. This study uses a multi-objective optimization model to explore future configurations of generating and cooling technologies of the electric power sector in the North China Grid subject to constraints imposed by existing policies on water conservation and carbon reduction in 2030. Our findings highlight that the current carbon reduction commitments of China do not have significant impacts on the North China Grid's electric power sector development while policies in the water sector generate much larger impacts. Imposing water constraint according to the ‘Three Red Line’ Policy requires increasing utilization of wind power and air cooling systems, which simultaneously increases economic cost and carbon emissions compared to the business as usual scenario. Imposing enhanced carbon emission and water consumption constraints reap the co-benefits of carbon reduction and water conservation by increasing the proportion of solar PV generation to 8.21%, which increases the unit electricity cost from RMB 0.82 per kWh to RMB 1.37 per kWh. In 2030, electricity generation in the North China Grid generates 1599.88 to 1690.89 million tons (Mt) of carbon emissions under different scenarios whereas imposing water constraint reduces water consumption from 3.34 billion m3 to 1.94 billion m3.

POTENTIAL AND DEVELOPMENT PROSPECTS ASSESSMENT OF ELECTRIC POWER INTEGRATION OF THE EURASIAN ECONOMIC UNION COUNTRIES

Existing approaches to the analysis of countries economic integration processes in international practice are investigated in the paper. Evaluating methodology of the long-term integration processes in the electric power sector is offered for the EAEU countries in three scenarios: high, low and medium, based on the synergy of various economic and mathematical methods. The actual methodology is formed in accordance with special macroeconomic scenario conditions and includes the final energy consumption forecast with division by the types of energy sources in the context of consumers categories of the EAEU countries based on generated scenario conditions using econometric methods (growth curves, Cobb-Douglas production function, regression analysis, simulation methods), as well as the development forecast of electric power industry concerning the EAEU countries reasoning from perspective dynamics of generating capacities of these countries. Project growth of electric power sector development founded on suggested method was made for the EAEU countries for the period of 2018-2040, specifically, electricity consumption projection, electricity consumption increasing, as well as capacity increasing of NPGS, HEP and RER in these countries. The necessity of further efforts to develop the common electric power market in the EAEU countries in order to obtain possible long-term integration effects are emphasized.

Optimizing Selection of Appropriate Power Generation Systems in Indonesia By Using Distance Based Approach Method

A deterministic quantitative model has been developed to compare the technical, economical and environmental feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for electricity generation systems in a developing country. Several energy sources which could be considered for production of electricity to meet current and future electricity demands have been chosen. These will include fossil fuel fired, nuclear, and natural-renewable energy power plants. And, a set of criteria for optimized selection includes five area of concerns: energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required are obtained from various sources related to power industry in Indonesia, such as the electricity generating authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The result of this study will be a ranking of energy sources for Indonesia power generation systems based on the Euclidean composite distance of each alternative to the designated optimal source of energy.

Electric Power Interconnection in North-East Asia: Towards a North-East Asian Energy Charter?

Compared with other regions, cooperative energy sector development between the countries of North-East Asia has to date remained unexplored. This situation appears to be changing, largely as a result of the intervention of the UN Economic and Social Commission for Asia and the Pacific (ESCAP), which has recently organised a North-East Asia Expert Group Meeting on Inter-Country Cooperation in Electric Power Sector Development. This article explores the recent developments in this field and considers the legal issues that may emerge over time.
