    Potential of hourly settlements in the residential sector of the Swedish electricity market: Estimations of risk reduction and economic result2010In: International Journal of Green Energy, ISSN 1543-5075, E-ISSN 1543-5083, Vol. 7, no 3, p. 224-240Article in journal (Refereed)
    Abstract [en]

    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 financial risk in customer segments with different heating systems as well as to estimate the potential of the electricity contract ”Fixed price with the right to return” in terms of economic consequences and risk management. The results show that households whose main heating system consists of a geothermal heat pump constitute the largest physical price and volume risk of suppliers. The gain of introducing hourly settlements in the residential electricity market has furthermore proven to be manifold from both an economic and risk reducing point of view.

    Exploring variance in residential electricity consumption: Household features and building properties2012In: Applied Energy, ISSN 0306-2619, E-ISSN 1872-9118, Vol. 92, p. 637-643Article in journal (Refereed)
    Abstract [en]

    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 variance in annual electricity consumption in single-family homes as well as to estimate the impact of household features and building properties in this respect using independent samples t-tests and one-way as well as univariate independent samples analyses of variance. Statistically significant variances associated with geographic area, heating system, number of family members, family composition, year of construction, electric water heater and electric underfloor heating have been established. The overall result of the analyses is nevertheless that variance in residential electricity consumption cannot be fully explained by independent variables related to household and building characteristics alone. As for the methodological approach, the results further suggest that methods for statistical analysis of variance are of considerable value in indentifying key indicators for policy update and development.

    Introducing a demand-based electricity distribution tariff in the residential sector: demand response and customer perception2011In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 39, no 9, p. 5008-5025Article in journal (Refereed)
    Abstract [en]

    Increased demand response is essential to fully exploit the Swedish power system, which in turn is an absolute prerequisite for meeting political goals related to energy efficiency and climate change. Demand response programs are, nonetheless, still exceptional in the residential sector of the Swedish electricity market, one contributory factor being lack of knowledge about the extent of the potential gains. In light of these circumstances, this empirical study set out with the intention of estimating the scope of households’ response to, and assessing customers’ perception of, a demand-based time-of-use electricity distribution tariff. The results show that households as a whole have a fairly high opinion of the demand-based tariff and act on its intrinsic price signals by decreasing peak demand in peak periods and shifting electricity use from peak to off-peak periods.

    Competence Development in Co-operation between Universities and Rescue Services2006Conference paper (Refereed)
    Abstract [en]

    In 2004 the Swedish government implemented the new Civil Protection Act. The new reformed legislation involved a number of significant changes, for the fire and rescue services as well as for local authorities, private companies and owners of buildings. The changes have created a need for education, both for persons involved in fire prevention in the public sector and in private companies. The new tasks that have been imposed the fire and rescue services also raise the demand for competence development among professionals. This paper discusses the changes and possibilities from a competence development perspective and describes how fire and rescue services and academic institutions can co-operate in gain for all parts.
