The potential for peak shaving on low voltage distribution networks using electricity storage

Co-location of energy storage with demand provides several benefits over other locations, while still being able to provide balancing services to the grid. One of these additional benefits is deferral of distribution infrastructure reinforcement, allowing increased load growth. This paper considers the potential of electricity storage for peak shaving on distribution networks, focusing on residential areas. A demand model is used to synthesise high resolution domestic load profiles, and these are used within Monte Carlo analysis to determine how much peak shaving could be achieved with storage. An efficient method of finding the potential peak shaving using electricity storage is developed for this purpose. It is shown that moderate levels of storage capacity can deliver significant demand reductions, if suitably coordinated and incentivised. With 2 kWh of battery storage per household, the peak demand at low voltage substations could potentially be halved. The effects of PV capacity, household size and C rates are considered. With 3 kW PV per house, 4.5 kWh of batteries could keep peak flows at the same level as before the addition of PV. It is also shown that 3 kWh of battery storage per household could allow provision of all heating from heat pumps without increasing t he peak demand

The role of governance in realising the transition towards sustainable societies

It is widely known that governance is central to the successful implementation of sustainable development policies and measures. Yet, there is a paucity of research which explore the links between governance and sustainability. This paper attempts to address this research need by providing an analysis of the role of governance in enabling – and to some extent – fostering a transition towards sustainable societies. A set of indicators for assessing the capacity for and willingness and commitment to transition to a more sustainable society is presented, enabling identification of direction of change. This paper presents the results of a study, in the context of which sustainability governance has been comparatively investigated in a sample of European countries with, by methodological purpose, very different economic, environmental, political and social conditions (Denmark, Finland, Germany, Latvia, Lithuania and Poland). Lessons learnt and examples of good practice – which may be replicable elsewhere-are outlined. For instance, it is discussed that limited knowledge about sustainable development amongst municipal development planners and decision-makers, deficiencies in policy integration, intersectoral cooperation, municipality and stakeholder cooperation and urban management practices are major reasons for weak governance practices in sustainable development. Furthermore, some recommendations on the role of sustainability governance are made, so as to allow the integration of the principles of governance into sustainability practice and hence provide a more general basis upon which a transition towards sustainable societies may become a reality in different types of European countries and societies. The scientific value of this paper lies in identifying opportunities for integrating principles of governance into sustainability practice, as well as outlining the basis for sustainability transitions, providing a general picture of required policy measures. The paper offers a unique comparative analysis of sustainability governance in the Baltic Sea countries, outlining some of the challenges in sustainability governance in the Baltic Sea region
