Abstract
Small-to-medium-sized enterprises (SMEs) make up 99% of businesses and contribute 13% of energy demand globally. However, much of the demand-side energy research and policy attention to date has focused on the domestic, large commercial and industrial sectors. Previous research on SMEs has primarily concentrated on the drivers and barriers to the adoption of energy efficiency measures. However, less attention has been given to other areas of demand-side management in SMEs, such as the role of ‘smart’ technologies and micro-generation. The paper aims to contribute to filling this gap. To analyse the potential of smart technologies in UK SMEs, a quantitative model is developed to assess seven categories of smart technologies in ten non-domestic sectors. Overall, the results suggest that smart technologies within the UK SME market offer significant estimated annual energy savings potential of ~£8.6 billion against an estimated energy spend of ~£49.7 billion (representing ~17% savings potential on energy expenditures). From the smart technology categories examined, fleet management, integrated building management systems and smart meters have the potential to offer the greatest energy savings to SMEs, providing estimated total energy savings of ~£7.5 billion annually. To analyse the potential of micro-generation in UK SMEs, interview-based qualitative research was undertaken with 17 SMEs to explore the drivers and barriers to its adoption. The research found that the initial costs, technical feasibility and planning permission on historical buildings were the main barriers, and that the ‘green’ marketing potential of micro-generation, coupled with ethical reasons and feed-in tariffs, were the main drivers.
Highlights
Small-to-medium-sized enterprises (SMEs) are an important, but poorly defined, set of diverse sectors and sizes that have received much less attention in demand-side energy research and policy than the domestic and large non-domestic sectors
It is important to note that as a result of the discussions in Table 3, the results broken down by sector and smart technology category are more interesting than the overall figures, as more studies are required to investigate any overlap in potential energy savings between smart technology categories
The paper aimed to contribute to improving the evidence base on demand-side management (DSM) in small-to-medium-sized enterprises (SMEs)
Summary
Small-to-medium-sized enterprises (SMEs) are an important, but poorly defined, set of diverse sectors and sizes that have received much less attention in demand-side energy research and policy than the domestic and large non-domestic sectors. There is no universally agreed definition of SMEs and the European Commission [1] has established a European Union (EU)-wide definition based on the number of employees (
