Decarbonizing the power sector forms a critical part of the global combat against climate change. This requires inter alia retirement of the global coal power plant fleet of 2,100 GW. Although a significant part of this capacity is aging, there are complex issues that need to be addressed including the economic viability of existing coal plants in some countries relative to renewable projects and barriers to exit of coal. We have used detailed power plant level operational cost data for ten developing countries with significant share of coal and compared these with levelized cost of renewables, to demonstrate that competitiveness of coal varies significantly across different geographies. Countries like India where renewable projects have been highly competitive and there is an aging fleet of coal plants many of which are far away from mines, are already highly uncompetitive. On the other hand, countries like South Africa that have relatively inexpensive coal plants, but the average cost of renewable projects have not yet dropped sufficiently (as of 2020), will require special efforts to phase out coal completely beyond plants that have reached, or gone well past their technical life. Accelerated retirement of coal would require a new business model that allows repurposing some of these sites for alternative usage including generation from renewables, conversion of the incumbent generator into a synchronous condenser coupled with a fly wheel to provide reactive power and inertia; and installation of energy storage systems. As a repurposed coal plant for energy related activities can retain part of the workforce, it can also address some of the complex social issues. In order to develop a comprehensive repurposing program a t a national level, the process needs to follow a leastcost planning methodology to identify prospective coal plant candidates for repurposing and then undertake a cost-benefit analysis of individual projects. We have demonstrated this methodology using a case study for Morocco.

“…Installed power capacity and electricity generation were consistently reported across papers. In addition, 15 sectoral scenarios (9 power sector papers) provided analysis of coal transitions (Shearer et al 2017, Malik et al 2020, short-term power sector developments (Laha et al 2020, Mukhopadhyay et al 2020, and long-term renewable development pathways (Gulagi et al 2017, Gadre andAnandarajah 2019).…”

“…Electricity demand growth is anticipated to be high enough to allow for India to meet its NDC low-emissions power goal while simultaneously increasing coal generation, especially if renewables growth does not keep up with the demand growth (Garg et al 2017, Gupta et al 2020b. Several of these scenarios estimate that coal capacity will increase to approximately 270-460 GW by 2030 (Byravan et al 2017, Chattopadhyay and Sharma 2017, Mathur and Shekhar 2020, Mukhopadhyay et al 2020; some expect it to increase as high as 550-740 GW (Shukla et al 2017, Mittal et al 2018 under high growth (8% annual GDP growth until 2030).…”

“…Reporting the type and amount of storage required is very important in the integration of high share VRE; yet most mitigation studies do not report these 8 . In addition, only a few scenarios investigate VRE integration at granular time steps, which is vital in understanding VRE supply and demand matching (Gulagi et al 2017, Laha et al 2020, Mukhopadhyay et al 2020. Further research is required to establish the feasibility of large-scale VRE integration in India.…”

India faces a dual challenge of economic development and responding to climate change. Although India’s per capita emissions are well below global average, the country is one of the world’s largest greenhouse gas emitters. Indian policymakers and stakeholders require high-quality data and research to assess low-emissions, sustainable development strategies. Peer-reviewed literature is a key source of this information and also a key venue for conversation amongst research leaders. This paper examines the recent peer-reviewed literature on India's 2030 and 2050 pathways. We conducted a systematic literature review to identify key quantitative national modeling studies. From the 34 studies identified, we synthesized scenario data to draw common conclusions and identify critical research gaps. The main focus was on examining the coverage and the state of information available on low-carbon pathways. Overall, we find a few scenarios that are potentially consistent with a 2070 net-zero goal, but more limited assessment of pathways to reach net-zero emissions before this date. Mitigation pathways with greater ambition are required across all energy sectors to ensure a smooth transition to net-zero emissions by or before 2070. The scenarios confirm that reducing emissions to below 2 GtCO2/year by mid-century would necessitate significant transformations of the Indian energy sector, such as, a decrease in unabated coal power capacity, transportation modal shift, and industrial process switching. The assessment also finds substantial differences in final energy estimates reported across studies, particularly in transportation. The lack of consistency in, and transparency about underlying drivers, assumptions, and even outputs across studies points to the critical need for the sorts of coordinated, multi-model studies that have proven exceptionally valuable for decision makers in other major emitting countries.

A Review on Wind Power Forecasting Regarding Impacts on the System Operation, Technical Challenges, and Applications

Wind energy generation is a fast developing efficient renewable source widely used for modern power generation. [1] Countries and energy companies have increased their interest in electricity generation from wind energy in the last decades, thanks to its natural, cost-free, and environmentally friendly features. [2] Wind power plants can generate electrical energy at any time of the day and are distributed energy sources for systems that need permanent energy. [3] Nonetheless, due to the disordered nature of the earth's atmosphere, there is a major uncertainty in the electrical power produced by the wind, which causes complexities in the utilization and management of wind energy sources. [4] The changes in weather conditions depending on time and location also create uncertainty in managing the supply-demand balance controlled by the grid operators. [5] In cases where the electrical energy produced by wind power plants is insufficient, auxiliary energy sources provide operational support to the electric grid. [6] Ensuring the supply-demand balance in the electricity grid is also an important condition for the electrical power quality and energy supply in the transmission system, and wind power plant operators care about the follow-up of wind power in terms of economy, operation, and planning. [7] For this, the presence of wind power forecasting (WPF) is an essential factor in the optimization of wind power plants. [8] For consumers to use electrical energy uninterruptedly, efficiently, and economically, wind power plant operators need to estimate the generated electrical energy smoothly. [9] The smooth estimation of electrical power generated by wind turbines increases the operational efficiency for system maintenance, planning, investment, and energy traders. [10,11] It is a precious procedure for electrical grids to provide a respectable commercial yield on the electrical energy market. [12] The capability of advanced WPF provides the contributions like balancing the power system and mitigation of penalties, scheduling the maintenance of wind power plants, investment regarding site location, and technoeconomic and socioeconomic benefits. [13,14] In this way, it is possible to reduce the energy cost and obtain high revenue in the energy market as a result of the contributions obtained for wind power generation systems. [15]
