This paper presents an insight into end-users' perception of smart grid products for households. The analysed products included three types of home energy management products (HEMPs) namely: smart thermostats, smart plugs and smart wall sockets. The analysis involved existing commercial HEMPs, as well as newly designed HEMPs from a students' project executed at University of Twente (Netherlands) in 2013 and 2014. Various industrial design methods were applied, and an online survey was utilised for data collection. The smart thermostat was considered the product with the greatest potential to stimulate energy-efficient behaviour. Features most preferred by end-users are: 1) visual display of energy information; 2) monitoring of energy use of appliances; 3) remote control, and expected ease of use. Appearance also appeared to have influenced the preferences of end-users regarding specific HEMPs. This study highlights the main features that household end-users desire in products that could stimulate energy-efficient behaviour.

Two residential Smart Grid pilots, PowerMatching City, Groningen (NL) and Pecan Street, Austin Texas (USA) have been compared regarding their energy performance and the experiences of users in these pilots. The objective of the comparison was to gain new insights that could support the successful deployment of future residential Smart Grids. Measured data on electricity generation and electricity consumption of households in 2013 and 2014 were evaluated. Existing reports with results of surveys of users were also analyzed. The energy performance revealed that the average domestic electricity consumption of households in PowerMatching City was lower compared to Pecan Street (2.6 GW h versus 10.1 GW h). At the same time, households in Pecan Street generated a higher amount of electricity compared to PowerMatching City (6.8 GW h versus 1.14 GW h). Households in Pecan Street consumed on average, 8% less electricity with respect to the USA average household domestic electricity consumption of 10.9 GW h; while households in PowerMatching City consumed 19% less electricity compared to the Dutch average household domestic electricity consumption of 3.1 GW h. Households in PowerMatching City appeared to have a higher potential to contribute to electricity demand and supply balancing, because their electricity consumption from the grid was largely reduced with increased self-generation. User experiences revealed that end-users in both pilots preferred technologies that automatically shift their energy use, since this requires minimal effort from them. We conclude that the pattern of households’ electricity generation and consumption in Smart Grid pilot projects, and their contribution to peak load balancing in the electricity network is largely influenced by existing Smart Grid set-ups, local climate and related needs for heating and cooling, the average capacity of installed energy generating technologies and the prevailing energy behavior.

Assessing residential Smart Grids pilot projects, products and services
Insights from stakeholders, end-users from a design perspective
The transition of the electricity system to smart grids would require from residential endusers to adapt to a new role of co-provider or active participants in the electricity system. End-users would for instance use energy efficiently, generate renewable energy locally, plan or shift energy consumption to most favourable times (such as when renewable energy is most abundant or during low peak periods), and trade self-produced electricity with other households. In a residential smart grid, a large part of the electricity supply in households will be generated by various decentralized energy resources like wind turbines, photovoltaic (PV) solar systems and micro-cogeneration systems. In this context, smart grids are supposed to provide the opportunity to make optimal use of renewable energy by matching demand to supply conditions, thereby facilitating the energy transition towards a more sustainable and less fossil fuel dependent society.

The transition of the electricity system to smart grids requires residential end-users to be more involved in managing energy demand and supply. New innovative products and services could help to support end-users to play a more active role in the management of the future electric power system. This paper evaluates the role of Industrial Design Methods (IDMs) in the development of new innovative smart grid related product concepts at the household level. Based on students' design projects, carried out within a master study programme, various IDMs were systematically utilized to develop new innovative products for smart grid households. Our study shows that five IDMs, namely: platform-driven product development, delft innovation model, theory of inventive problem solving, technology roadmapping, and innovative design and styling were mainly applied in the development of the conceptual products. This study shows that a thorough and careful application of various IDMs helped to develop inspiring potential smart grids product concepts that could support end-users at the household level to gain more insight into their energy use, and contribute to balancing energy demand and supply. These concepts include various in-home displays, smart plugs, and smart wall sockets. The resulting product concepts are presented in this paper. We conclude that the systematic use of various IDMs helped to identify and incorporate various technological, societal, market, and end-user aspects necessary for creating innovative smart grid related products that meet end-user and future market expectations.
