This article deals with the challenges of balancing the need for hydroelectricity with the impact on the environment. Economic efficiency, energy security, and environmental sustainability are concerns that must be considered ...

Portfolios of renewable electricity sources are interesting risk-management mechanisms for trading in electricity contract markets. When formed by players belonging to different companies, their stability relies on the way ...

The main challenge with the penetration of variable renewable energy (VRE) in thermal-dominated systems has been the increase in the need for operating reserves, relying on dispatchable and flexible resources. In the case ...

Capacity mechanisms are now deemed a regulatory mainstay in liberalised power system decarbonisation. These instruments aim to ensure sufficient resource adequacy with a mix able to meet the reliability target set by the ...

The implementation of auctions of long-term electricity contracts is arising as an alternative to ensure generation investment and therefore achieve a reliable electricity supply. The aim is to reconcile generation adequacy ...

The objective of this work is to investigate possible hydro-scheduling inefficiencies under a bidding scheme. It will be shown that the market-based dispatch of hydro-plants, under a perfect competitive market, converges ...

In this paper, we present a bilevel programming formulation for the problem of strategic bidding under uncertainty in a wholesale energy market (WEM), where the economic remuneration of each generator depends on the ability ...

Most countries that have recently reformed their energy sectors are looking carefully at California. An unprecedented electric power deficit has affected one of the main economies of the world, threatening to bankrupt two ...

Many countries use auctions to select agents to which transmission concessions are awarded. Where multiple concessions are auctioned each year, there are potential benefits, for transcos and grid users, in using auction ...

South America is looking for ways to harmonize power supply expansion with growing environmental concerns as electricity demand increases at a fast pace. While South America contributed little to the world's total pollutant ...
