Investigating Preconditions for Sustainable Renewable Energy Product–Service Systems in Retail Electricity Markets

Energy transitions are complex and involve interrelated changes in the socio-technical dimensions of society. One major barrier to renewable energy transitions is lock-in from the incumbent socio-technical regime. This study evaluates Energy Product–Service Systems (EPSS) as a renewable energy market mechanism. EPSS offer electricity service performance instead of energy products and appliances for household consumers. Through consumers buying the service, the provider company is enabled to choose, manage and control electrical appliances for best-matched service delivery. Given the heterogenous market players and future uncertainties, this study aims to identify the necessary conditions to achieve a sustainable renewable energy market. Simulation-Based Design for EPSS framework is implemented to assess various hypothetical market conditions’ impact on market efficiency in the short term and long term. The results reveal the specific market characteristics that have a higher chance of causing unexpected results. Ultimately, this paper demonstrates the advantage of implementing Simulation-Based Design for EPSS to design retail electricity markets for renewable energy under competing market mechanisms with heterogenous economic agents

Modeling Tradeoff in Ship Breaking Industry Considering Sustainability Aspects: A System Dynamics Approach

AbstractShip breaking industry provides incentives for developing countries. Thus, it presents economic catalyst for the country. On the other hand, ship-breaking activity contributes hazardous material that result ecological imbalance for the exposure area. Moreover, ship-breaking process by any standard is dangerous occupation because intoxication by dangerous substances and accident that happened on the plots. In the light of these, economics benefit and social-environmental loss regarding to ship-breaking industry is debatable. This study observes the tradeoff between loss and benefit of ship breaking industry. A model for ship breaking industry considering economics, environmental and social issue was constructed using System Dynamic. Proposed model captures the variable sensitivity while each variable is interacting with another. The result can be considered on regulation and policy implementation regarding to ship-breaking and its aspects, specifically in developing countries

Designing and Evaluating Energy Product-Service Systems for Energy Sector (EPSS) in Liberalized Energy Market: A Case Study in Space Heating Services for Japan Household

This paper introduces Energy-Product-Service Systems (EPSS) to overcome the issues in the liberalized energy market. Currently, conventional energy services are highly commoditized, thus eroding their competitiveness in a liberalized energy market. In addition, customer benefits from the current system are hard to analyse, because it is difficult for customers to observe the quality of the results of energy consumption. EPSS incorporates energy sector with other related sectors to design and deliver immediate result of energy usage that suit to customer’s specific needs is expected to provide better performance than current system. However, EPSS service design and implementation involve high risk and performance uncertainties. Therefore, this study proposes a method to design and to evaluate EPSS and compare its performances with energy product/service performance in current system through Simulation-Based Design (SBD). SBD is used to construct EPSS service considering stakeholders’ interest and to evaluate the service performance, by simulating alternative scenarios in order to seek conditions that are expected to fulfil stakeholders’ requirements. In the proposed analysis, three service features, that is, service consumption management, operational system design and electricity supply management are introduced and used to develop EPSS alternative design for space-heating service. Afterwards, customer satisfaction and the company’s benefit for each service scenarios are simulated and compared with the performance of the current system. In this context, EPSS design that includes operational system design and electricity supply management results in better benefit for all stakeholders

A Framework to Manage Co-creation Process for PSS Considering the Network and Technology

9th CIRP IPSS Conference: Circular Perspectives on PSS.This paper provides a preliminary study of framework development to manage co-creation process in order to improve customer satisfaction and environmental performance. The study clarified the importance to manage co-creation process for PSS. The discussion on PSS and Co-creation process reveals similarity regarding network and technology requirement to establish the system implies that co-creation process naturally embedded in PSS. Nevertheless, managing the co-creation process become another challenge. To manage co-creation process for PSS, this paper identified the influential factors of co-creation process considering the network and technology. The factors that included in the networks are number of actors, degree of centrality, diversity of actors and network density. The influential factors of co-creation process from technology perspective are modularity and system interoperability. The expected benefits for the company will be in terms of knowledge of co-creation management under product-service system
