Abstract Lack of investment in the electricity sector has created a huge bottleneck in the continuous flow of energy in the market, and this will create many problems for the sustainable growth and development of modern society. The main reason for this lack of investment is the investment risk in the electricity sector. One way to reduce portfolio risk is to diversify it. This study applies the concept of portfolio optimization to demonstrate the potential for greater use of renewable energy, which reduces the risk of investing in the electricity sector. Besides, it shows that investing in renewable energies can offset the risk associated with the total input costs. These costs stem from the volatility of associated prices, including fossil fuel, capital costs, maintenance, operation and environmental costs. This case study shows that Iran can theoretically supply ~33% of its electricity demand from renewable energy sources compared to its current 15% share. This case study confirms this finding and predicts that Iran, while reducing the risk of investing in electricity supply, can achieve a renewable energy supply of ~9% with an average increase in supply costs. Sensitivity analysis further shows that with a 10% change in input cost factors, the percentage of renewable energy supply is only partially affected, but basket costs change according to the scenario of 5–32%. Finally, suggestions are made that minimize risk rather than cost, which will bring about an increase in renewable energy supply.

The Media

This study aims to analyse the media management strategy of Indonesian television stations during the Covid-19 pandemic. In March 2020, an outbreak of the Covid-19 pandemic in Indonesia affected the operations of broadcasting offices, which forced people to work from home. This situation affects the operations, strategy, and content of the television industry. The object of research is Kompas TV, one of the largest media companies in Indonesia, which was the first to implement a digital concept for its customers. The concepts of planning, organising, actuating, and controlling are used to analyse the strategies media utilised. The methodology employed for the current research takes the form of a case study by adopting the qualitative approach through an in-depth interview and observation. The results showed that Kompas TV, through its digital platform in the form of websites, YouTube channels, and social media, achieved an increase in the number of viewers, users, and engagement during the pandemic. In particular, the digital aspect does not only appear in communication, but also in the implementation of the Kompas TV strategy. The results of the study also revealed that strategies carried out on Kompas TV can be used as a model for other television in Indonesia to emulate, in order to sustain its business in times of crisis.

Study Approach

The electricity sector was negatively impacted by the coronavirus disease (COVID-19), with considerable declines in consumption in the initial phase. Investors were in turmoil, and stock prices for these companies plummeted. The aim of this paper is to demonstrate the significant negative influence of the pandemic on abnormal returns for the electricity sector, specifically for traditional and renewable companies and the influence of ESG scores, using the event study approach and multi-variate regressions. Our results show that the pandemic indeed had a negative impact on the electricity sector, with renewable electricity companies suffering a sharper decline than traditional ones. Moreover, we find that ESG pillar scores affected electricity companies differently and are sector-specific. For renewable electricity companies, the returns were positively influenced by the environmental ESG scores and negatively by governance ESG scores.

The identification of irregular users is an important assignment in the recovery of energy in the distribution sector. This analysis requires low error levels to minimize non-technical electrical losses in power grid. However, the detection of fraudulent users who have billing does not present a generalized methodology. This issue is complex and varies according to the case study. This paper presents a novel methodology to identify residential fraudulent users by using intelligent systems. The proposed intelligent system consists of three fundamental modules. The first module performs the classification of users with similar power consumption curves using self-organizing maps and genetic algorithms. The second module allows carrying out the monthly electricity demand forecasting through of recursive adjustment of ARIMA models. The third module performs the detection of fraudulent users through an artificial neural network for pattern recognition. For the design and validation of the proposed intelligent system, several tests were performed in each developed module. The database used for the design and evaluation of the modules was constructed with data supplied by the energy distribution company of the Colombian Caribbean Region. The results obtained by the proposed intelligent system show a better performance versus the detection rates obtained by the company.

AbstractThis chapter introduces Understanding Energy Innovation, a book that is about the process of digital innovation within the electricity sector, with a focus on the social and political. This chapter covers who the book is for, its aims and themes, summarises key theories of energy innovation, and defines smart grids. Smart grids involve the incorporation of new digital and information and communication technologies into utility infrastructures, and they are used as a case study throughout the book to explore energy innovation. The chapter concludes with a brief history of smart grids.

This case study analyzes one senior living and social service organization’s coronavirus (COVID-19) crisis response. We conducted interviews with n = 14 department managers to explore the organization’s pivot to remote work and service provision. We used the Pearson and Mitroff Crisis Management Framework to organize themes. A pre-existing culture of teamwork, willingness to adapt and adopt new approaches, and responsiveness to new policies and procedures facilitated the COVID-19 crisis response. However, low levels of digital literacy among staff, decreased job satisfaction due to no face-to-face interaction between care recipient and service provider, and lack of proactive policies for crisis response, which decreased the speed of enacting remote service provision, were obstacles in effective crisis response. Lessons learned from this case study highlight the need for pre-emptive policy creation on remote service provision and work from home policies, as well as training considerations for senior living and social service organizations.
