Smart Meter-Angebote: Eine empirische Untersuchung von Kundenpräferenzen

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes.

Privacy in AI and the IoT: The privacy concerns of smart speaker users and the Personal Information Protection Law in China

In recent years, the development of Artificial Intelligence (AI) and the Internet of things (IoT) has attracted a lot of attention. One IoT device is the smart speaker that is equipped with an integrated assistant controlled by spoken commands. In the global smart speaker market, Chinese brands account for a significant share. Since smart speakers have a natural advantage when collecting user data in diverse scenarios, privacy and personal information protection have become crucial issues for both smart speaker manufacturers and users in China. This paper applies the socio-technical system (STS) framework to portray the technology subsystem, the industry/market subsystem and the regulators, law/regulation subsystem that are related to smart speakers in China, and how they interact with each other. It also uses focus group discussions to understand the smart speaker users' privacy concerns and the smart speaker industry's implementation of personal information protection. By employing the document analysis method, this study analyzes the laws and regulations related to privacy and personal information protection in the context of AI and the IoT. In particular, the potential impacts of the Personal Information Protection Law (PIPL) on smart speakers are discussed in detail. With its goal of balancing personal information protection and technological development, this paper provides recommendations for the regulatory bodies and the smart speaker industry players in China that can shed light on other countries and regions.     

Stromspeicher im Quartier

Electricity storage is a possible flexibility option to increase the share of fluctuating electricity sources from renewable energies in the electricity system. In the past, most attention was paid to household and large storage facilities. Community storage solutions at the meso level have so far been largely neglected. It is only in the context of the change in legislation for the electricity supply of tenants that neighborhood solutions have recently been increasingly discussed.In essence, this article examines the challenges currently arising in the context of the implementation of electricity storage facilities at community level in Germany. To this end, the term “community storage” is first being discussed and outlined. Subsequently, economic-legal and socio-cultural challenges are presented and discussed as central challenges in the implementation of neighborhood storage solutions in Germany. Based on the discussion of current challenges, possible business models for the implementation and operation of district storage facilities in Germany will then be derived.

Einflussfaktoren auf die Bereitschaft von Privatkunden, Ökostrom nachzufragen

The present study investigates impacts of attitudinal and perceptual characteristics of residential electricity consumers on their intention to use a green power tariff/supplier in the future. The work rests on a standardized telephone survey of 267 household electricity consumers of a German power supplier. Multivariate Partial Least Squares analysis indicates that, regardless of a person’s level of actual power consumption in the recent past, the intention to use green electricity is significantly higher among customers who have a positive general attitude towards environmental protection measures and who report an endorsing valuation of green power by their close social contacts. In a subsample of participants with a low actual electricity consumption in the year preceding the survey the intention to use green energy is significantly positively affected by the weight an individual attaches to electricity prices in one’s own supplier selection decisions and the person’s belief that one’s present power company takes over social responsibility. In contrast, in the subgroup of respondents with a high actual electricity consumption customers’ intention to use green energy is significantly enhanced by the degree of perceived dissimilarity among power company offerings. The findings are used to derive suggestions for green energy marketing measures of power companies and future energy consumer research.     

Effizientes Engpassmanagement zur Schaffung eines europäischen Strombinnenmarktes — die Rolle von finanziellen Übertragungsrechten

This paper assesses possible market designs for cross border electricity trading. The methodical approach is to split up and evaluate cross border trading into a long term and a short term perspective in a first step and afterwards reunite the two perspectives to find an optimal market design. Two possible congestion management systems are considered for each timeframe. After establishing test criteria, efficient long and short term congestion management systems are identified. As a next step the optimal solution out of the four integrated market designs is identified. These findings are followed by an analysis of the prerequisites for the implementation of the optimal market design. The paper arrives at the conclusion that the optimal market design for cross border electricity trade depends on the development of the electricity market and needs to be adapted in accordance with the actual maturity of the electricity market.
