Vietnam is among the countries that are assumed to be highly affected by the impacts of climate change through sea level rise; increased temperature and changes in precipitation resulting in changes in crop water requirements and yields; and changes in river flow with impacts on hydropower and...

It is well established within both the economics and power system engineering literature that hydro power can act as a complement to large amounts of intermittent energy. In particular hydro power can act as a battery where large amounts of wind power are installed. In this paper I use simple...

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...

When a monopolistic hydro producer interacts with a competitive thermal fringe, the short-run revenue function of the hydro monopolist is non-concave. This implies that even if the demand function is stationary, equilibrium prices may fluctuate through the year. For given capacities, both hydro...

An important conclusion from the literature on hydropower is that if there are no other constraints than the available water reservoirs for a year, and operating costs are ignored, the competitive (and socially optimal) outcome is characterized by the (present value) price being constant through...

The key question in hydropower production is the time pattern of the use of the water in the reservoir. The water used to produce electricity today can alternatively be used tomorrow. The analysis of the operation of hydropower is therefore essentially a dynamic one. The paper introduces some...

Many countries have followed a policy of being self-sufficient in electricity. However, in the last two decades exchange of electricity across borders has become more widespread, and the European Union's policy is to encourage a gradual expansion of cross-border trading and integration of...
