The diffusion of renewable energy in the power system implies high supply variability. Lacking economically viable storage options, renewable energy integration has so far been possible thanks to the presence of fast-reacting mid-merit fossil-based technologies, which act as back-up capacity....

The economics of electricity is shaped by its physics. A well know example is the non-storability of electricity that causes its price to fluctuate widely. More generally, physical constraints cause electricity to be a heterogeneous good along three dimensions - time, space, and lead-time....

Over the coming decade, the power sector is expected to invest ~7.2 trillion USD in power plants and grids globally, much of it into CO2-emitting coal and gas plants. These assets typically have a long lifetime and commit large amounts of (future) CO2 emissions. Here, we analyze the historic...

This paper presents an overview of the reasons why unregulated markets for the production of electricity cannot be expected to invest sufficiently in generation capacity on a continuous basis. Although it can be shown that periodic price spikes should provide generation companies with sufficient...

The United Nations General Assembly declared 2012 the "International Year of Sustainable Energy for All", officially recognising the urgent need to put energy at the centre of the global development agenda. In parallel, a strong international policy effort is being made to achieve the goal of...

Europe's power system is still marked by a distinct national component, and despite some regions with strongly integrated power systems, electricity supply today still has a largely national basis. Policies to decarbonise the power sector may fundamentally alter this situation, because power...

This paper examines the role of electricity production from biomass with and without carbon capture and storage in sustaining low CO2 emission pathways to 2100. It quantifies the effect of the availability of biomass resources and technologies within a general equilibrium framework. Biomass-fed...

In Italy and in many EU countries, the last decade was characterized by a large development of distributed generation power plants. Their presence determined new critical issues for the design and management of the overall energy system and the electric grid due to the presence of discontinuous...
