“…In particular, some regions rely on coal combustion to meet peak demand, and combining BESS with renewable generation resources may further increase profitability while avoiding emissions associated with electricity generation. ,,− Other energy storage technologies like redox flow batteries or hydrogen storage may ultimately prove to be better suited for peaker replacement as they mature. − Additionally, uncertainty in near-term energy supply may cause variation in market sizes and structure, altering future revenues. , Finally, the modeled NPVs also do not capture the monetized human health impacts tied to rolling blackouts or prolonged outages, − as well as the nonhealth community impacts associated with the removal of natural gas combustion peaker plants . Including these considerations may increase the value of BESS, especially since greater renewable integration and worsening effects from climate change increase the variability of electricity supply and demand. − …”

Falling costs of lithium-ion (Li-ion) batteries have made them attractive for grid-scale energy storage applications. Energy storage will become increasingly important as intermittent renewable generation and more frequent extreme weather events put stress on the electricity grid. Environmental groups across the United States are advocating for the replacement of the highest-emitting power plants, which run only at times of peak demand, with Li-ion battery systems. We analyze the life-cycle cost, climate, and human health impacts of replacing the 19 highest-emitting peaker plants in California with Li-ion battery energy storage systems (BESS). Our results show that designing Li-ion BESS to replace peaker plants puts them at an economic disadvantage, even if facilities are only sized to meet 95% of the original plants’ load events and are free to engage in arbitrage. However, five of 19 potential replacements do achieve a positive net present value after including monetized climate and human health impacts. These BESS cycle far less than typical front-of-the-meter batteries and rely on the frequency regulation market for most of their revenue. All projects offer net air pollution benefits but increase net greenhouse gas emissions due to electricity demand during charging and upstream emissions from battery manufacturing.

“…There is rising concerns in the North America, especially the United States, about the opposing environmental influences from greenhouse gas emissions cause by burning fossil fuel and power generation, so there is required a modification as an academical planning solve the problem (Steele et al, 2021). From a positive viewpoint, the sustainable energy transition in the region is well ongoing as the provision to the coal, gas, and oil industries is transferred to the sustainable RE as an alternative.…”

“…However, region's energy policy and management, either the energy is from renewable or non-renewable resources, is a mixture of private and public co-decision-making at the regional, national, and local levels. Assimilating RE to enhance the grid system effectiveness with facilitating technologies such as energy storage, responsive load, waste heat, hydrogen fuel cell, and smart grid machineries should have more investigations (Steele, et al, 2021). Further, an enable business environment in uncertainty related to investments risks, as well as technology costs increasing is still missing.…”

This study provides a data-driven analysis that illustrates a clear renewable energy depiction in sustainable energy security and unveils the regional issues due to the literature solely occupies energy security concept in the descriptions view, and renewable energy differences related to regions are rarely discussed. A hybrid method is proposed to valid those indicators and shows the trend of future studies. This study enriches the challenges and opportunities by contributing to understand the fundamental knowledge of renewable energy in sustainable energy security frontier, conveyance directions for future study and investigation, and assessment on global renewable energy position and regional disparities. There are valid 19 indicators, in which energy demand, energy policy, renewable resources, smart grid, and uncertainty representing the future trends. World regional comparison includes 115 countries/territories and categorized into five geographical regions. The result shows that those indicators have addressed different issues in the world regional comparison.

“…Thus, it is crucial to study the impacts of the intermittent RES on the overall system reliability. The authors of [59] investigated RES effects on the power system to find out whether increasing the share of wind and solar PV in electricity generation has an adverse effect on the power system. Based on their empirical study in the U.S., they concluded that at first, increasing the net generation from wind and solar PV has a negative impact on the grid reliability.…”

Wind and Solar Intermittency and the Associated Integration Challenges: A Comprehensive Review Including the Status in the Belgian Power System

Renewable Energy Sources (RES) have drawn significant attention in the past years to make the transition towards low carbon emissions. On the one hand, the intermittent nature of RES, resulting in variable power generation, hinders their high-level penetration in the power system. On the other hand, RES can aid not only to supply much more eco-friendly energy but also it allows the power system to enhance its stability by ancillary service provision. This article reviews the challenges related to the most intermittent RES utilised in Belgium, that is, wind energy and solar energy. Additionally, wind speed and solar irradiance variations, which are the cause of wind and solar intermittency, are studied. Then, recent techniques to forecast their changes, and approaches to accommodate or mitigate their impacts on the power system, are discussed. Finally, the latest statistics and future situation of RES in the Belgian power system are evaluated.
