Investments in power generation assets are risky due to high construction costs and long asset lifetimes. Technology diversification in generation portfolios represents one option to reduce long-term investment risks for risk-averse decision makers. In this article, we analyze the impact of...

Germany’s nuclear phase out and an increasing share of fluctuating RES production amplifies the North-South congestion problem in the German electricity grid. But congestion management becomes a serious issue not only in the German but in the whole European electricity system as German...

La politica energetica europea, che doveva trovare un equilibrio tra sicurezza energetica, compatibilità ambientale e competitività è cresciuta con molte ambizioni mal riposte, in mezzo alle quali la competitività è passata in secondo piano. La crescita incontrollata degli incentivi agli...

The allocation or assignment of the emissions permits is one of the most contentious elements of the design of cap-and-trade systems In this paper we develop a detailed representation of the U.S. western electricity market to assess the potential impacts of various permit allocation proposals....

This paper describes a model of the 2020 Irish electricity system which was developed and solved in a mixed integer programming, unit commitment and economic dispatch tool called PLEXOS®. The model includes all generators on the island of Ireland, a simplified representation of the neighbouring...

The official Danish energy plan “Energy 21” calls for a very high penetration of wind energy in the electricity sector. This will put issues of fitting a variable energy source into a stable supply system in focus. The present study investigates the role that collaboration with the...

The purpose of this article is to determine whether the geographic dispersion of solar-photovoltaic panels reduces variability in energy production. Following this, three questions are posed: 1) If geographic dispersion reduces variability, how dispersed should the panels be?; 2) What happens...

Similar to other European countries, mechanisms for the promotion of electricity generation from renewable energy sources (RESs) and combined heat and power (CHP) production have caused a significant growth in distributed generation (DG) in Spain. Low DG/RES penetration levels do not have a...

Photovoltaic (PV) cells, onshore wind turbines, internet technologies, and storage technologies have the potential to fundamentally change electricity markets in the years ahead. Photovoltaic cells are the most disruptive energy technology as they allow consumers of all sizes to produce power by...

Drawing from relevant experiences in power systems around the world, this paper offers a review of existing policy support mechanisms for RES-E, with a detailed analysis of their regulatory implications. While recent studies provide an account of current RES-E support systems, in this paper we...
