Abstract [en]

In the last decades, energy modelling has supported energy planning by offering insights into the dynamics between energy access, resource use, and sustainable development. Especially in recent years, there has been an attempt to strengthen the science-policy interface and increase the involvement of society in energy planning processes. This has, both in the EU and worldwide, led to the development of open-source and transparent energy modelling practices. This paper describes the role of an open-source energy modelling tool in the energy planning process and highlights its importance for society. Specifically, it describes the existence and characteristics of the relationship between developing an open-source, freely available tool and its application, dissemination and use for policy making. Using the example of the Open Source energy Modelling System (OSeMOSYS), this work focuses on practices that were established within the community and that made the framework's development and application both relevant and scientifically grounded.

Abstract [en]

Low-carbon hydropower is a key energy source for achieving Sustainable Development Goal 7-sustainable energy for all. Meanwhile, the effects of hydropower development and its operation are complex-and potentially a source of tension on Transboundary Rivers. This paper explores solutions that consider both energy and water to motivate transboundary cooperation in the operation of hydropower plants (HPPs) in the Drina River Basin (DRB) in South-East Europe. Here the level of cooperation among the riparian countries is low. The Open Source energy Modeling System-OSeMOSYS was used to develop a multi-country model with a simplified hydrological system to represent the cascade of HPPs in the DRB; together with other electricity options, including among others: energy efficiency. Results show that improved cooperation can increase electricity generation in the HPPs downstream without compromising generation upstream. It also demonstrates the role of inexpensive hydropower to enhance electricity trade in the region. Implementing energy efficiency measures would reduce the generation from coal power plants, thereby mitigating CO 2 emissions by as much as 21% in 2030 compared to the 2015 levels. In summary, judicious HPP operation and electricity system development will help the Western Balkans reap significant gains.

Abstract [en]

The EU remains widely dependent on external gas supplies, with imports representing 70% of its consumption in 2013. Member States have different import profiles with divergent levels of dependency on Russian imports. Several European Member States rely heavily on Russian supplies, which shows that the EU gas supply security needs to be examined both from an internal and international perspective. Since the 2009 crisis between Russia and Ukraine, the EU has adopted several legislative tools to strengthen EU gas security of supply. The third legislative package, the security of supply Regulation (EU) 994/2010 and the Energy Infrastructure package identifying Projects of Common Interest have significantly improved the ability of the EU to face import disruptions. However, several countries remain particularly vulnerable to the occurrence of disruption. When considering national production, storage, and the diversity of suppliers, Bulgaria, Czech Republic, Estonia, Finland, Latvia, and Lithuania seem to be at risk. Romania, Poland, and Hungary also import the bulk of their gas from Russia, but have either domestic production or significant storage capacity.

Abstract [en]

In September 2015, the United Nations General Assembly adopted Agenda 2030, which comprises a set of 17 Sustainable Development Goals (SDGs) defined by 169 targets. 'Ensuring access to affordable, reliable, sustainable and modern energy for all by 2030' is the seventh goal (SDG7). While access to energy refers to more than electricity, the latter is the central focus of this work. According to the World Bank's 2015 Global Tracking Framework, roughly 15% of the world's population (or 1.1 billion people) lack access to electricity, and many more rely on poor quality electricity services. The majority of those without access (87%) reside in rural areas. This paper presents results of a geographic information systems approach coupled with open access data. We present least-cost electrification strategies on a country-by-country basis for Sub-Saharan Africa. The electrification options include grid extension, mini-grid and stand-alone systems for rural, peri-urban, and urban contexts across the economy. At low levels of electricity demand there is a strong penetration of standalone technologies. However, higher electricity demand levels move the favourable electrification option from stand-alone systems to mini grid and to grid extensions.

Abstract [en]

With an increasing penetration of variable renewables in the EU in recent years, the flexibility of its power system is of critical importance. In this chapter, we first assess flexibility considerations in the past, prior to market liberalization. We then analyze the impact of increasing penetration of renewables on flexibility requirements. Further, we identify existing options to provide this flexibility. Finally, we use model-based analysis, we quantitatively assess potential solutions to deploying temporary production and storage. Business models and potential evolutions of the legislative framework associated with the different solutions are also proposed.

Abstract [en]

At present, power supply in the EU is characterized by a relatively high reliability. It should, however, not be taken for granted given the increasing shares of variable RES. Choosing the socioeconomically optimal level of reliability to aim for requires a thorough understanding of the socioeconomic costs of electricity supply interruptions. This chapter provides guidance on how to measure the consequences of supply interruptions and thus determine the value of electricity supply security.

Abstract [en]

Energy storage has increasingly come into focus as a key transformational technology in the energy system. This is driven by several factors, including: (1) the increased electrification of the energy system and the associated changes in demand patterns, driven by new loads such as electric vehicles and heat pumps; (2) the decarbonization of the power system and the associated increases in the penetration of variable renewable electricity production, and related security of supply concerns. In this chapter we explore the evolving role of storage in the EU energy system-both at present and in the future. This includes proposed changes in current legislative frameworks to support the diffusion of storage technologies-a key enabler in the EU's transition to a reliable, flexible, and affordable energy system.

Abstract [en]

The generation mix of Cyprus has been dominated by oil products for decades. In order to conform with European Union and international legislation, a transformation of the supply system is called for. Energy system models can facilitate energy planning into the future, but a large volume of data is required to populate such models. The present data article provides information on key modelling assumptions and input data adopted with the aim of representing the electricity supply system of Cyprus in a separate research article. Data in regards to renewable energy technoeconomic characteristics and investment cost projections, fossil fuel price projections, storage technology characteristics and system operation assumptions are described in this article.

Abstract [en]

Africa is a resource-rich continent but lacks the required power infrastructure. Efforts such as the United Nations Sustainable Energy for All and U.S. President Obama's Power Africa initiatives aim to facilitate much needed investment. However, no systematic national and regional investment outlook is available to analysts. This paper examines indicative scenarios of power plant investments based on potential for electricity trade. OSeMOSYS, a cost-optimization tool for long-term energy planning, is used to develop least cost system configurations. The electricity supply systems of forty-seven countries are modelled individually and linked via trade links to form TEMBA (The Electricity Model Base for Africa). A scenario comparison up to 2040 shows that an enhanced grid network can alter Africa's generation mix and reduce electricity generation cost. The insights have important investment, trade and policy implications, as specific projects can be identified as of major significance, and thus receive political support and funding.

Abstract [en]

Water and energy supply are strongly interrelated and their efficient management is crucial for a sustainable future. Water and energy systems on several Greek islands face a number of pressing issues. Water supply is problematic as regards both to the water quality and quantity. There is significant lack of water on several islands and this is mainly dealt with tanker vessels which transport vast amounts of water from the mainland. At the same time island energy systems are congested and rely predominantly on fossil fuels, despite the abundant renewable energy potential. These issues may be addressed by combining desalination and renewable energy technologies. It is essential to analyse the feasibility of this possibility. This study focuses on developing a tool capable of designing and optimally sizing desalination and renewable energy units. Several parameters regarding an island's water demand and the desalination's energy requirements are taken into account as well as input data which concern technological performance, resource availability and economic data. The tool is applied on three islands in the South Aegean Sea, Patmos (large), Lipsoi (medium) and Thirasia (small). Results of the modelling exercise show that the water selling price ranges from 1.45 (sic)/m(3) for the large island, while the corresponding value is about 2.6 (sic)/m(3) for the small island, figures significantly lower than the current water cost (7-9 (sic)/m(3)).
