TVA and the other federal electric utilities were created under Democratic administrations, and their service territories were initially bluer than average. These subsidized enterprises sell cheap power preferentially to non-investor-owned distributors, so such distributors are more prominent...

The overlapping impact of the Emission Trading System (ETS) and renewable energy (RE) deployment targets creates a classic case of interaction effects. Whereas the price interaction is widely recognized and has been thoroughly discussed, the effect of an overlapping instrument on the abatement...

In the process of regulatory reform in the electric power industry, the mitigation of market power is one of the basic problems regulators have to deal with. We use experimental data to study the sources of market power with supply function competition, akin to the competition in wholesale...

It is widely accepted that in liberalized electricity markets log-returns display fat-tailed densities. Besides qualitative assessments, so far precise characterizations of the shape of the distribution have been seldom provided. In this work, we characterize the conditional and unconditional...

In uniform price, sealed-bid day-ahead electricity auctions, the market price is set at the intersection between aggregate demand and supply functions built by a market operator. Each day, just one agent - the marginal generator - owns the market-clearing plant. Day-ahead auctions are moreover...

The evidence of volatility-price dependence observed in previous works (Karakatsani and Bunn 2004; Bottazzi, Sapio and Secchi 2005; Simonsen 2005) suggests that there is more to volatility than simply spikes. Volatility is found to be positively correlated with the lagged price level in settings where...

Deutschland hat im internationalen Vergleich bereits seit langem sehr hohe Strompreise. Da Strom teilweise aus Gas erzeugt wird, haben sich die Preise infolge des Ukrainekriegs weiter erhöht. Aber auch die gestiegenen CO2-Preise zur Reduzierung des CO2-Ausstoßes wirken weiter preistreibend....

In einer im Mai 2010 von der Wirtschaftsfördergesellschaft Vorpommern mbH (WFG) in Zusammenarbeit mit kreislichen und städtischen Wirtschaftsförderern sowie der Fachhochschule Stralsund, Fachbereich Wirtschaft, durchgeführten branchenübergreifenden Unternehmensbefragung zur Zufriedenheit...

High levels of wind power penetration will tend to affect prices in a deregulated electricity market. Much of the analysis in the literature has focused on the effect that wind power has on average electricity prices, this paper attempts to test the effect that wind power production has on the...

Nonlinear autoregressive Markov regime-switching models are intuitive and frequently proposed time series approaches for the modelling of electricity spot prices. In this paper such models are compared to an ordinary linear autoregressive model with regard to their forecast performance. The...
