Demand Response has become a central focus in policy discussions, attracting heightened attention for its potential key role in fostering enhanced demand flexibility. Direct Load Control (DLC) holds particular promise, requiring reduced consumer involvement compared to strategies relying on manual responses to time-varying pricing. However, the par...

Demand-side flexibility is often encouraged via demand response programs, where users are incentivized to adjust their electricity consumption based on price signals in tariffs. The design and implementation of these signals are vital, as they link conditions of the energy system with user behaviour. As a result of energy system separation into sta...

Reducing peak demand in distribution grids is associated with benefits such as delayed infrastructural investments , decreased losses and a reduced risk of power deficits. One instrument aimed at reducing peak demand is the demand charge, a capacity-based component in a network tariff that intends to encourage users to reduce their peak usage. Usin...

Evaluations of price-based demand response programs tend to focus on users' electricity use patterns and/or their practical experiences. Less is known about the effects that price-based demand response programs have on cognitive drivers and barriers to energy-using behaviors and habits, or how well these predict timing of households' electricity us...

Local flexibility markets (LFM) for electricity are in their early stages, and most research has focused on their design aspects and aggregators, while little attention has been paid to providers and potential providers of flexibility resources. The present research aims to fill this gap by analysing data from 25 in-depth interviews with enrolled a...

Demand response refers to changes in power consumption by electricity users in response to certain conditions on the electricity market. Anticipated to play a major role in the energy transition, demand response is conventionally exercised through network tariffs, which serve as a medium for price signals intended to incentivize and guide electrici...

Conventionally, demand response functions by communicating to electricity users through price signals embedded in their tariffs. These signals are intended to encourage a change in behavior, which hinges on the ability of users to understand their tariff and link it to the appropriate curtailment actions. This study focuses on demand-based tariffs,...

Demand-based charges have been employed as a tool intended to reduce electricity users’ maximum demand but there is a lack of consensus regarding their efficacy. One reason for this may be the diversity in the flexibility potential of different types of users. This study explores the flexibility potential of different types of electricity consumers...

A microgrid’s self-consumption rate reflects its ability to retain its own energy and decrease its reliance on the synchronous grid. This paper investigates the empirical case of a microgrid equipped with photovoltaic (PV) panels and identifies challenges in engaging the microgrid’s users to increase their self-consumption. Accordingly, we explored...

When households invest in photovoltaics, they change from being electricity consumers to solar prosumers, a change that is often implied to also positively affect other pro-environmental behaviours. This article presents a comparison between Swedish consumers and prosumers (N = 460), concerning (i) whether consumers and prosumers engage in pro-envi...

Studies suggest that householders who turn prosumers become more energy aware, change their pattern of electricity use and may even start to engage in other pro-environmental activities. However, few of these studies were equipped to investigate such causal relationships - mainly because most prosumers are inherently self-selected. However, as real...

To enable and cope with an increase of intermittent electricity generation, the power industry and regulators are trying to incentivise users to use electricity at certain times through dynamic pricing and feedback. The effects of such interventions on patterns of electricity use have been extensively studied, yet little is known about how and why...

As peak demand for electricity continues to rise, distributors have begun charging small and medium-sized users for their short term demand rather than just their energy use. This is not only to meet the political aspirations for increased demand-side flexibility that now exist in many corners of the world, but to make sure that users are charged f...

Household energy consumption can be curbed by individuals’ energy saving, yet despite many efforts, our energy consumption is not lowering. This study investigated the role of a common set of behavioural determinants for households’ intention to perform four energy-related behaviours: investing in PV cells, turning off apparatus on standby mode, sh...

This is a research project report that we wrote for Energiforsk - an organisation funding energy-related research. This popular science report in Swedish, written for Energiforsk, presents a case study of a "market-driven" electricity distribution tariff including a billing demand charge introduced by the DSO Sandviken Energi Elnät AB in 2015. The...

Demand response (DR) from end-users is widely investigated as a power-system flexibility resource in a European smart-grid environment. Limited knowledge exists on the added value such flexibility can bring to actors in the electricity value chain. This work investigates the economic effect of consumption flexibility under current regulatory remune...

Smart grids play a key role in realizing climate ambitions. Boosting consumption flexibility is an essential measure in bringing the potential gains of smart grids to fruition. The collective scientific understanding of demand response programs argues that time-of-use tariffs have proven its merits. The findings upon which this conclusion rests are...

Current transmission and distribution units are designed to cope with extreme cases of maximum power demand, which sparsely occur. Dimensioning the grid to such specifications for the purpose of meeting temporary peak load is a costly endeavor which can be lowered via exploitation of load modification. Demand response potential is estimated to be h...

This paper aims at investigating how the implementation of smart grids takes place in the context of the Swedish power market. We performed an exploratory study that in its first step has pinpointed the key actors involved in smart grid implementation. In this respect, we have identified several public and private organizations that are relevant to...

Improved means of controlling electricity consumption plays an important part in boosting energy efficiency in the Swedish power market. Developing policy instruments to that end requires more in-depth statistics on electricity use in the residential sector, among other things. The aim of the study has accordingly been to assess the extent of varia...

In light of global warming, energy conservation is indispensable. Residential electricity use, nevertheless, escapes consumers' notice. Thus feedback is essential, yet households' access to information is extemely limited. Smart metering makes continuous feedback over the internet possible, but users perceive existing web tools to be inaccessible a...

Increased demand response is essential in order to boost the effectiveness of the Swedish power market. The all-embracing installation of automatic meter reading systems enables power suppliers to introduce hourly settlements in the residential sector. The aim of the study has been to assess the impact of electricity retailers' physical and financi...

We have had a strong mechanism for interaction between power production companies and the power trading/supplier companies for a number of years by now. In the future we can expect new types of more interactive communications between single customers and groups of customers towards the energy market companies. We can also expect a stronger demand-s...

In Sweden the deregulation of the electricity market has increased the demand of efficient and accurate short term prognosis. Top-down models are today widely used for both planning and prognosis. The top-down models are known as accurate and effective when working with data in a well known domain, but can have problems estimating new trends in con...

A determining factor for a successful implementation of a demand-based pricing model or control strategy in electricity markets is not only the effects of peak load management, but also the economical consequences for the utility operator and the end customer. In this economical modeling a subset of 460 residential customers has been implemented in...

Characteristics of national cultures influence companies' approach to business. Cultural divergence between nations consequently has an impact on international business relations. Based on an empirical study, which was conducted in accordance with the Grounded Theory approach, this article claims that, if mismanaged, cultural divergence has a negat...
