The Internet of Things penetrates all areas of life and work, giving physical objects the characteristics of digital technologies. Also, in the energy sector, physical products such as photovoltaic systems, battery storage systems, and thermostats are equipped with smart and connectivity components and become smart energy products. Smart energy products enable new types of services that are smart energy services. For example, a smart thermostat can offer an intelligent preheating service based on data collected and analyzed. Against this background, smart energy services offer new business potentials for companies as well as added value for private households. To benefit from this development, companies need an understanding of the characteristics and capabilities of the products and the services building on them. Smart energy services, in particular, appear promising, as services are seen as a bridge to the customer. However, there is little research that supports the design of smart energy services. To close this gap, a morphological analysis of smart energy services along several dimensions is conducted. In highlighting the unique characteristics of smart energy services, the paper provides a more nuanced picture on the nature of smart energy services and their potential in terms of new consumer and business values. Additionally, the phenomenon of consumer-oriented smart energy services will be further conceptualized, and the morphological box can be considered a structured approach for the design of smart energy services.
