The Cost

Cheap and clean energy demand is continuously increasing due to economic growth and industrialization. The energy sectors of several countries still employ fossil fuels for power production and there is a concern of associated emissions of greenhouse gases (GHG). On the other hand, environmental regulations are becoming more stringent, and resultant emissions need to be mitigated. Therefore, optimal energy policies considering economic resources and environmentally friendly pathways for electricity generation are essential. The objective of this paper is to develop a comprehensive model to optimize the power sector. For this purpose, a multi-period mixed integer programming (MPMIP) model was developed in a General Algebraic Modeling System (GAMS) to minimize the cost of electricity and reduce carbon dioxide (CO2) emissions. Various CO2 mitigation strategies such as fuel balancing and carbon capture and sequestration (CCS) were employed. The model was tested on a case study from Pakistan for a period of 13 years from 2018 to 2030. All types of power plants were considered that are available and to be installed from 2018 to 2030. Moreover, capacity expansion was also considered where needed. Fuel balancing was found to be the most suitable and promising option for CO2 mitigation as up to 40% CO2 mitigation can be achieved by the year 2030 starting from 4% in 2018 for all scenarios without increase in the cost of electricity (COE). CO2 mitigation higher than 40% by the year 2030 can also be realized but the number of new proposed power plants was much higher beyond this target, which resulted in increased COE. Implementation of carbon capture and sequestration (CCS) on new power plants also reduced the CO2 emissions considerably with an increase in COE of up to 15%.

The Cost

- The debate on the benefits of nuclear energy revolves around the very competitiveness of this energy source. This article tries to show why it is not easy to answer unambiguously the question whether or not it is convenient to resort to nuclear power in a given country. After listing the factors on which the cost of electricity generation rests and discussing the range of probability of their value, the levelized cost of electricity generation from nuclear, coal and gas-fired plants is calculated using the Monte Carlo method. The results show that nuclear power is likely to be competitive, especially if policies to combat CO2 emissions will continue in the coming decades. There are, however, some margins of uncertainty, mainly related, to the one hand, to the cost of nuclear plants, that depends on the socio-institutional context, and on the other, to the fossil fuels cost, that are inherently difficult to anticipate even on average. Finally it is noted that the context of liberalized electricity markets may make it more difficult for investors to accept the risk of investing in nuclear power plants and for the community to socialize some of the costs associated with this technology.Key words: Nuclear energy, generation costs, Montecarlo method, environmental impacts.JEL classifications: G11, H23, L72, L94, Q31, Q40

Environmental, political, and economic events seem to conspire simultaneously towards the objective to erase coal-fired power plants. The most important events are: the increase of environmental regulations, the surge of natural gas as a cleaner fuel, the operative costs, the aging and the efficiency issue of the coal-fired power plants. However, the decision of the U.S.A. Supreme Court, the 29th of June 2015, suspended the regulation proposals presented by the U.S.A. Environmental Protection Agency concerning the mercury emissions of coal-fired power plants. This decision caused debate and controversy. The main objective of the sustainable approach for electricity generation is to find the blending of fuels that decrease contamination. However, the contradiction of different events in the world poses the challenge to evaluate if the XXI Century will see the end of the coal era. Could the technological breakthroughs like the Carbon Capture and Sequestration (CCS) and the development of other Clean Energy Technologies on Coal (CCT) stop this trend or, will the financial and environmental profitability of coal help it to remain in the energy mix?

This paper assesses the relative economic and jobs benefits of retrofitting an 847 MW USA coal power plant with carbon capture, utilization, and storage (CCUS) technology compared to replacing the plant with renewable (RE) energy and battery storage. The research had two major objectives: 1) Estimate the relative environmental, economic, and jobs impacts of CCUS retrofit of the coal plant compared to its replacement by the RE scenario; 2) develop metrics that can be used to compare the jobs impacts of coal fueled power plants to those of renewable energy. The hypotheses tested are: 1) The RE option will reduce CO2 emissions more than the CCUS option. We reject this hypothesis: We found that the CCUS option will reduce CO2 emissions more than the RE option. 2) The RE option will generate greater economic benefits than the CCUS option. We reject this hypothesis: We found that the CCUS option will create greater economic and jobs benefits than the RE option. 3) The RE option will create more jobs per MW than the CCUS option. We reject this hypothesis: We found that the CCUS option will create more jobs per MW more than the RE option. We discuss the implications of these findings.

The Impact

In order to achieve a high renewable share in the electricity system, a significant expansion of cross-border exchange capacities is planned. Historically, the actual expansion of interconnector capacities has significantly lagged behind the planned expansion. This study examines the impact that such continued delays would have when compared to a strong interconnector expansion in an ambitious energy transition scenario. For this purpose, scenarios for the years 2030, 2040, and 2050 are examined using the electricity market model PowerFlex EU. The analysis reveals that both CO2 emissions and variable costs of electricity generation increase if interconnector expansion is delayed. This effect is most significant in the scenario year 2050, where lower connectivity leads roughly to a doubling of both CO2 emissions and variable costs of electricity generation. This increase results from a lower level of European electricity trading, a curtailment of electricity from a renewable energy source (RES-E), and a corresponding higher level of conventional electricity generation. Most notably, in Southern and Central Europe, less interconnection leads to higher use of natural gas power plants since less renewable electricity from Northern Europe can be integrated into the European grid.
