Also, industrial symbiosis with the aim of providing district heating in Aalborg and prerequisites for energy transitions are addressed.

An already developed model - Electricity Planning-Low Carbon Development (EP-LCD) - was adapted and modified to examine the nonlinear relationship between generation adequacy and greenhouse gas (GHG) emission reduction for better targeted strategic regional intervention on climate change. Two broad scenarios - Base and LCD Option - were tested for the West African Power Pool (WAPP). The cost impact of increasing generation capacity in the LCD Option was estimated at US$1.54 trillion over a 50 year period. Achieving the goal of low carbon pathway would be largely influenced by government decision. Four strategies, in line with the Nationally Determined Contribution in Paris Agreement, were recommended. These are: a) enforced improved efficient electricity generation through increased energy efficiency that should result in increased capacity factor; b) decreased energy intensity of economic activities to result in reduced emission factor in existing plants; c) attract new investment through low tax or tax exemption to reduce cost of constructing power plants for the benefit of base-load plants; and d) subsidized cost of low-carbon fuels in the short run to benefit intermediate load plants and allow for the ramping up of low-/no-carbon fuel generation capacity. These are recommended considering the region’s specific economical and political conditions where funds are tremendously difficult to raise. Implementing these recommendations will allow the electric power industry in West Africa to contribute to achieving sustainable development path.</em></p> Abiodun Suleiman Momodu ##submission.copyrightStatement## Mon, 15 Jan 2018 15:09:39 +0100 The effect of price regulation on the performances of industrial symbiosis: a case study on district heating <p>This study of the district heating system of Aalborg (Denmark) analyses how fiscal instruments affect the extent excess heat recovery helps reduce the carbon footprint of heat. It builds on a supply-and-demand framework and characterizes the changes in excess heat supply with consequential life cycle assessment in reference to one gigajoule distributed. The heat supply curve is defined through ten scenarios, which represent incremental shares of excess heat as the constraints of the said legal instruments are lifted. The heat demand curve follows the end-users’ response to price changes. The most ambitious scenario doubles the amount of excess heat supplied and reduces the heat carbon footprint by 90% compared to current level, for an end-user price increase of 41%. The price increase results from a higher supply of excess heat at a higher price and an unchanged purchase cost from the coal-fired CHP plant despite a lower supply. This highlights the necessity of a flexible supplier when the share of recovered excess heat is high.</p> Romain Sacchi, Yana Konstantinova Ramsheva ##submission.copyrightStatement## Mon, 15 Jan 2018 15:09:39 +0100 Understanding the local energy transitions process: a systematic review The objective of this paper is to better understand the local energy transitions process, given the importance of local energy transitions. A systematic literature search was conducted and 18 core and 18 peripheral papers on local energy transitions were selected. The 18 core papers were assessed using the framework given by Turnheim et. al. [1]. Findings show that local energy transitions have characteristics or features which are not adequately explained by the framework used. Sources of innovation and the innovation in niches in local energy transitions are explained by socio-technical theories such as Strategic Niche Management (SNM) and Multi-Level Perspective (MLP). The pathway dynamics and the normative goals are covered by quantitative modeling studies of local energy transitions. The specific features of local energy transitions which are not adequately analysed by the existing framework are ownerships of transitions, situative governance issues, spatial scale issues, differing priorities and differing institutional structures, along with the analysis of pathway dynamics. A suggestion for extending a framework to analyse local energy transitions is proposed. Sujeetha Selvakkumaran, Erik O.
