How can increasing intermittent power generation in the Swedish electricity system be managed in a more market-oriented and cost-efficient way? We argue that market mechanisms are the most natural means for obtaining the needed flexibility in electricity systems. We believe that a complete ex...

Renewable energy such as wind or solar power currently contributes a large share to the total German electricity supply as a result of the German energy transition. This paper presents an empirical analysis of how power shocks resulting from intermittent renewable supply affect forward premiums...

The long-run development of power markets will be deeply affected by the gradual substitution of fossil fuel-based generation technologies by renewable energy technologies (RES). However, the intermittent supply of RES, in combination with the temporal non-homogeneity of electricity demand,...

The disaster at Fukushima has clearly illuminated some of the issues, which operating an energy market through regionally isolated monopolies give rise to. At the same time, a shift towards renewable energies is increasingly being perceived as necessary in Japan. In order to achieve this...

We evaluate how increasing wind generation affects wholesale electricity prices, balancing payments and the cost of subsidies using the Irish Single Electricity Market (SEM) as a test system, with hourly data from 1 January 2008 to 28 August 2012. We model the spot market using a system of...

This paper estimates the impact of solar and wind power intermittency on wholesale prices, arbitrage opportunities and the profitability of storage. First, I use the short term randomness of wind and solar generation to estimate the hourly reductions in wholesale electricity market prices...

It is expected that the renewable share of energy generation will rise considerably in the near future. The intermittent and uncertain nature of renewable energy (RE) calls for storage and grid management technologies that can allow for increased power system flexibility. To assist policy makers...

This paper studies the links between non-renewable and intermittent renewable energy sources in the production of electricity. We argue that the relationship between the price of natural gas and investments in solar and wind capacity is non-linear and can be represented by an inverted-U shape....

This paper develops a dynamic model of competitive equilibrium in electricity markets with thermal, hydro and intermittent power sources. Thermal generators have positive and increasing costs and use a marketable input. Hydro generators use a free and uncertain input, but one that is storable....
