El almacenamiento de electricidad constituye una potente herramienta para la operación del sistema a la hora de maximizar la integración en el sistema eléctrico de la generación procedente de energías renovables. En este artículo se repasan las principales tecnologías de almacenamiento...

En este ensayo, se concluye la necesidad y urgencia de llevar a cabo un paquete de medidas, preferiblemente de forma consensuada en un pacto de estado, para paliar o eliminar los graves problemas del sector y cumplir, a nivel satisfactorio, con los tres principios aceptados de seguridad de...

Adopting a zonal structure of electricity market requires specification of zones’ borders. In this paper we use social welfare as the measure to assess quality of various zonal divisions. The social welfare is calculated by Market Coupling algorithm. The analyzed divisions are found by the...

We compare two competing methodologies of market zones identification under the criterion of social welfare maximization: (i) consensus clustering of Locational Marginal Prices over different wind scenarios and (ii) congestion contribution identification with congested lines identified across...

Adopting a zonal structure of electricity market requires specification of zones’ borders. One of the approaches to identify zones is based on clustering of Locational Marginal Prices (LMP). The purpose of the paper is twofold: (i) we extend the LMP methodology by taking into account variable...

Why do states adopt renewable portfolio standards (“RPSs”)? Many have suggested that RPSs mark a “race to the top,” where states adopt more and more stringent regimes in an effort to compete for clean energy jobs. This article challenges that presumption. It shows, by examining empirical...

Capacity remuneration mechanisms are a widespread instrument to foster investment. The growing interest in electricity storage raises the question how these mechanisms interact with storage plants. Using a stylized capacity planning model, we demonstrate that an exclusion of storage plants from...

Electric and natural gas are the two major sources of energy for residents of Washington State. Several states have adopted a policy whereby utility companies decide on the choice of mixes of resources by incorporating cost effectiveness, conservation and externalities. Externalities could...

Emission trading has become recently more and more import in environmental regulation. In the context of controlling greenhouse gas emissions, the directive on a Europewide trading scheme for large immobile sources may be perceived as one of the most important milestones in recent years. Prior...

Coal was the largest source of electricity generation in the United States for decades before being supplanted by natural gas in 2015. Nuclear plants have also been a significant electricity source in America but now many of them are on the verge of closing. Meanwhile, the amount of electricity...
