This paper investigates preference heterogeneity among Slovenian energy consumers and attempts to ascertain how different consumer groups value various attributes of energy products and services. More specifically, it aims to establish whether a consumer segment can be identified that shows a preference for additional energy services—in particular services, associated with energy-efficient and green behaviour. A latent class analysis is employed to classify consumers on the basis of their preferences for energy services. Additionally, information about their attitudes and behaviour toward green energy and energy efficiency, energy consumption, and usage of energy services together with socio-economic characteristics is used in the latent class regression to explain differences between latent consumer classes. Three classes are identified: the largest class of regular consumers, energy-efficient consumers, and dissatisfied consumers. In contrast to regular and dissatisfied consumers, energy-efficient consumers show a significantly higher interest in additional services, energy efficiency, and green energy. In line with the found heterogeneity of consumer preferences, suppliers should customise marketing strategies to meet the needs of specific segments. Energy policymakers also need to pay more attention to consumer heterogeneity and behavioural changes to increase the effectiveness of energy efficiency policies.

This study assesses the effectiveness of the Slovenian subsidy program introduced in 2009 on household decisions for energy-efficient building retrofits. A discrete choice regression model with individual random effects is estimated, using a retrospective panel data of 6,882 Slovenian households covering the period from 2006 to 2014. The objective of this study is to identify factors that influence the decisions of Slovenian households to undertake energy-efficient retrofits of their homes and to examine the effectiveness of the subsidy program. The results reveal decisive factors for implementing energy-efficient retrofits to be a household’s financial status, past retrofit activity, the location of homes, the building’s age and type, and electricity expenditures. Regional climate differences and economic activity (GDP p.c.) also trigger energy-efficient retrofits. During the period between 2009 and 2011, the subsidy program proved to be ineffective, implying the presence of free-riders. In contrast, evidence on the positive effect of the program on retrofit rates in the years 2012 to 2014 was found with a varying share of free-riders. In 2012, free-ridership was not detected, coinciding with a significantly increased amount of available funds, while in the following years the share of free-riders increased to 52.3% and 62.0%, respectively.

The transition of residential energy markets following liberalisation has enhanced the development of new marketing strategies in order to increase consumers’ activity in the market, as well as to satisfy current climate change policies. This work explores the relationship between consumer preferences for energy services and participation in loyalty programs as a new marketing strategy in competitive energy markets. A conceptual framework of membership in loyalty program options is developed and empirically tested. In addition to consumer preferences for energy services extracted by principal component analysis, explanatory variables in the multinomial regression model also include other control variables. An empirical analysis is conducted on a sample of residential electricity consumers of the largest energy supplier in Slovenia, a new entrant in the electricity market. This research suggests three main findings. First, consumer preferences defining consumer types significantly differ across the loyalty program consumer groups, which calls for tailoring the supply offer to respond to different consumer segments. Second, members of the regular loyalty program option prefer a good relationship with the supplier, while for members of the advanced loyalty program option, integrated energy services play a bigger role. Third, loyalty programs could be effectively used to target the advanced segment of consumers with an offer of integrated energy services, including energy efficiency and green energy, thereby contributing to the mandatory energy savings imposed on energy suppliers and the national environmental sustainability targets.
