Summary: This study aims to fill the gap in electricity demand modeling in Malawi and provide policy insights for the country's electricity future. The study employs a projection methodology using demographic, economic, and government policy trends, and analyzes three different electricity use scenarios. Through this study, insights and recommendations regarding the status of Malawi's electricity sector and policy influence can be provided to various planners and stakeholders in the power sector.

Summary: Decarbonizing the electricity system to zero-carbon emission is crucial for climate change mitigation, but this transition may lead to increased costs in the U.S. electric power sector. This study presents a regionally resolved model to quantify the cost of decarbonizing the U.S. electricity system and finds that reaching zero CO2 emission by 2050 would incur an additional cost of 335-494 billion USD, depending on different scenarios. Regional costs of electricity generation vary due to generation profiles and renewable resource availability. Furthermore, the cost of mitigating the last few percent CO2 emission may exceed the costs of negative emission technologies, indicating an opportunity for their contribution to electricity decarbonization.

Summary: A climate neutral energy system in Germany is likely to require green hydrogen. The import price for green hydrogen and the upper limit for photovoltaic installations are two uncertain factors that determine whether the hydrogen will be imported or produced locally. The authors conducted cost optimization calculations for climate neutral energy systems while varying these two factors to investigate their impact. Hydrogen plays a significant role in most scenarios and is highly correlated with photovoltaic power.

Summary: This paper proposes a data-driven model based on Fourier analysis for long-term prediction of electricity market prices. By decomposing the electricity price into different components and using relevant energy and market data for prediction, this method is capable of accurately predicting the dynamics of electricity prices and has the ability to generalize.

Summary: The paper presents a plan for achieving the carbon neutral target in the EU-27 by 2050, utilizing a multi-period mixed-integer programming model to maximize sustainability net present value. Wind farms and solar photovoltaics are highlighted as the most promising solutions for expanding renewable energy generation, with the potential to create over 1.5 million new job opportunities across the EU.

Summary: This study uses LEAP to analyze the various scenarios of electrical energy generation and consumption in Egypt from 2020 to 2050, based on data provided by the Egyptian authorities. The study examines the energy mix under different demand projections and explores the impact of increasing the share of renewable energy. The results show a decline in natural gas contribution by 2050, reaching its peak in the NON scenario and dropping to less than 16.5% in the REN 70 scenario. The study also finds that renewable scenarios have the lowest long-term production cost compared to other scenarios.

Summary: This paper investigates the role of a demand response (DR) aggregator in participating in the entire electricity market on behalf of end-users. By trading acquired DR in the short-term market, the aggregator can increase flexibility and maximize profit. It is found that having an energy storage system (ESS) has a significant impact, as it provides more flexibility and allows for energy storage during low-price periods and discharge during high-price periods, increasing profit. Therefore, having an appropriately sized ESS can maximize the aggregator's profit.

Summary: By ratifying the Paris Agreement, the Republic of Serbia has committed to reduce greenhouse gas emissions by 13.2% by 2030 compared to the 2010 levels. This study aims to define sustainable scenarios for the transition process of the electricity generation sector in Serbia, utilizing the country's significant potential for renewable energy sources. The proposed scenarios promote the sustainable use of renewable energy for electricity generation and show a significant reduction in CO2 emissions compared to the reference year.

Summary: This paper addresses the long-term electricity procurement portfolio optimization problem faced by an electricity Retailer. A novel optimization model was formulated to quantify the optimal mix of asset options that covers the Retailer's forecasted load portfolio in the most efficient way on a yearly basis. The model takes into account the technical, operating, and financial aspects of each asset option to determine the timing, capacity, and overall cost of the optimal mix.

Summary: This research aimed to analyze the energy consumption of an nZEB restaurant in a typical city to anticipate tourist numbers. The restaurant's energy comes from solar panels and electricity grids, with hydrogen storage used to store excess energy. The Fanger model was used to assess passenger thermal comfort, while Trnsys software evaluated the transient performance of the nZEB throughout a year. PV panels supplied most of the restaurant's electricity, and hydrogen tanks stored excess electricity. Solar collectors generated hot water and a heat pump provided cooling and heating. The results demonstrated the effectiveness of utilizing ZEB on the building roof area to reduce Doha's greenhouse gas emissions significantly.

Summary: This study analyzes different policy approaches to curb emissions and finds that strengthening emissions trading incentives and forcing coal exit can significantly reduce CO2 emissions and bring welfare gains. Avoided CO2 emissions can also be achieved through a system-optimal expansion of renewable energy, leading to further welfare gains.

Summary: This study examines the charging and discharging patterns of utility-scale batteries in the California market and finds that battery owners only respond to price incentives during certain hours. The deployment of batteries between 2013 and 2017 has reduced average intra-day wholesale price spreads. However, the profitability of batteries in this market is currently limited by market conditions.
