European electricity markets are geographically organized in zones, which often resemble countries. Overload of power lines within zones have to be relieved through other means than the electricity market, e.g. so-called “redispatching” of power plants. Traditionally, this has often been...

Previous studies have noted that, surprisingly, Germany’s dramatic expansion of wind and solar energy coincided with a reduction of short-term balancing reserves. This paper provides further and updated evidence, supporting this “German Balancing Paradox”: since 2011 wind and solar energy...

This paper proposes a game-theoretic model to analyze the strategic behavior of inc-dec gaming in market-based congestion management (redispatch). We extend existing models by considering incomplete information about competitors’ costs and a finite set of providers. We find that these...

The inherent variability of wind speeds affects the price the wind power generators receive when selling their output on the market (market value). During windy times the additional supply of electricity at zero marginal costs shifts the supply curve (merit-order curve) to the right and thereby...

The variability of wind and solar power crucially affects their social value. This paper determines the welfare-optimal market share of wind and solar power under different technology, price, and policy assumptions, focussing on the impact of variability. A numerical electricity market model...

Most production processes can be turned off easily during times of low demand; this is not true for the generation of electricity. For a number of technical reasons, a certain number of conventional (thermal) power stations needs to keep producing electricity at all times, despite negative...

The economics of electricity is shaped by its physics. A well know example is the non-storability of electricity that causes its price to fluctuate widely. More generally, physical constraints cause electricity to be a heterogeneous good along three dimensions - time, space, and lead-time....

Control power (regulating power, balancing power) is used to quickly restore the supply-demand balance in power systems. Variable renewable energy sources (VRE) such as wind and solar power are often thought to increase the reserve requirement significantly. This paper provides a comprehensive...

Energy and climate policies are usually seen as measures to internalize externalities. However, as a side effect, the introduction of these policies redistributes wealth between consumers and producers, and within these groups. While redistribution is seldom the focus of the academic literature...
