In many countries, the electricity systems are quitting the vertically integrated monopoly organization for an operation framed by competitive markets. In such a competitive regime one can ask what the optimal management of the nuclear generation set is. We place ourselves in a medium-term...

The aim of this work is to analyse the agents’ behaviour in highly concentrated and strongly regulated electricity wholesale markets with rigid demand. In order to accomplish this aim, the analysis was based on the former Spanish electricity generation market, between January 1999 and June...

This paper describes the current state of the Macedonian electricity sector. It looks at ongoing structural changes, driven by the gradual adoption of the EU acquis on energy, and comes up with estimates for electricity subsidies. It concludes by discussing the longer term outlook and sketching...

The German support for renewable energies in the electricity sector is based on the feed-in tariff for investors that grants guaranteed revenues for their renewable energy supply. Corresponding to differences of granted tariffs and respective market values, a surcharge on consumption covers...

Regulators and market participants have become increasingly concerned about the Spanish electricity tariff deficit due to its size and the difficulties to control its growth. The deficit can be traced to inefficiencies in market organization and solutions should be designed to mitigate those...

The problem of trend-cyclic component filtering from price time-series arises in many commodity market studies, including those of wholesale electricity market. The long-term component filtering is an important part of price analysis since incorrect determination of this component may result in...

Stimulating measures for the production of electrical energy from renewable energy sources (RES) are guaranteed over certain period of operation. Their aim is that the wind power plants (WPP) and other RES are brought to a concurrent position with the conventional power plants at the open market...

The paper considers one of the economic mechanisms, stimulating the introduction of renewable energy sources (RES)—a green certificate market. A mathematical model was developed to describe a supply and demand balance in the electricity and green certificate markets simultaneously. The sellers...

Japan׳s Fukushima nuclear disaster, triggered by the March 11, 2011 earthquake, has led to calls for shutting down existing nuclear plants. To maintain resource adequacy for a grid׳s reliable operation, one option is to expand conventional generation, whose marginal unit is typically fueled by...

The aim of this paper is to show the economic potential of demand response (DR) on household level at Central European market conditions. Thereby, required economic benefits for consumers' participation, the realistic load shifting potential at household level and the estimation of essential...
