An electricity generation system adequacy assessment aims to generate statistically significant adequacy indicators given projected developments in, i.a., renewable and conventional generation, demand, demand response and energy storage availability. Deterministic unit commitment (DUC) models with exogenous reserve requirements, as often used in today's adequacy studies to represent day-to-day power...
The push to integrate massive Renewable Energy Sources (RES) puts the future development of power systems under significant uncertainties. This study analyses a private investment in Pumped Hydro Storage (PHS) operating in a zonal market characterized by transmission congestion between zones. This study shows negative NPV values for the investment in PHS technology in two Italian zones. The profit...
Investment models for decision making on unconventional hydrocarbon resource development in Europe must be based on realistic estimates of well productivity, gas price projections and reliable data concerning the costs of the project. In this analysis we assess the economic feasibility of three different investments projects in coal bed methane production located in three European regions: Cheshire...
This study contributes to the current discussion on the economic viability of new investments in electricity storage technologies, its environmental impact in terms of CO2 emissions and level of renewables in the system and some policy related questions. The analysis is based upon a price-taker model under perfect price forecast simulating the dispatch of a marginal pumped-hydro storage (PHS) plant...
This study analyses how sources of flexibility in the system can affect the end users' level of electricity prices. In particular, we want to investigate whether flexibility sources like electricity storage technologies and renewable power curtailment change consumers' expenditure for electricity purchase. The final cost of purchasing power for end-consumers can be used as an indicator of the level...
In 2014 EU leaders agreed on a new framework for 2030 for climate change and energy policies. By 2030 targets renewable power in the European market should be at least 27% of the EU's energy consumption. This major change will require the deployment of flexible technologies to ensure stability and security of supply. In this paper we study the role of electricity storage and renewable power curtailment...
This study assesses the profitability of an investment in a pump hydro storage plant (PHS) located in Italy. We model in GAMS the operation of a price-taker PHS during nine years, from 2005 to 2013. Results show positive operation profits in all regions, with the highest results being recorded by the geographical zones SICI and SARD. The NPV analysis shows negative values though, ranging between −148...
