Technoeconomic assumptions adopted for the development of a long-term electricity supply model for Cyprus

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.

Need for Flexibility and Potential Solutions

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.

Gas Security of Supply in the European Union

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 ...

Storage Solutions and Their Value

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.

Need for Reliability and Measuring Its Cost

Abstract 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.
