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. This paper attempts to...

This paper attempts to empirically identify the key factors involved in the decision to scrap a wind turbine using data from Denmark. The importance of the opportunity cost of operating an older wind turbine is shown to be a prominent factor in the decision to scrap. I show the strong effect...

Dynamic optimization problems cover a great class of problems in theoretical and applied economics and technology. In this account the exploitation of a general renewable capital stock is modeled through an alternative formulation to the classical optimal control approach. We propose a very...

One may misread economic theory on climate policy to provide a warning against unilateral mitigation. While important lessons are drawn from ‘global problems require global solutions’, these say little about what to do in a phase before or without a global agreement - or with weak ones. In...

Studies have shown that many consumers and businesses fail to invest in energy efficiency improvements despite seemingly ample financial incentives to do so – the so-called energy efficiency gap. Attempts to explain this gap often focus on searching costs, information frictions and behavioral...

The new Basel III regulations are likely to make long-term financing more expensive, which will affect the financing of capital-intensive renewable energy technologies, because they typically rely on long-term financing. In addition, the capital and liquidity requirements of Basel III are likely...

Dynamic optimization problems cover a large class of problems in theoretical and applied economics. A simple iterative algorithm with fast convergence is proposed. It is demonstrated that the algorithm in a few steps produce excellent analytic (closed form) approximations including error bounds...

This paper attempts to empirically test the effect that wind power production in Denmark has on volatility of the nordpool wholesale electricity prices. The main result is that wind power tends to significantly reduce intraday volatility but increases volatility over larger time windows. The...

Presently in the Nordic day-ahead market, zonal pricing or market splitting is used for relieving congestion between a predetermined set of price areas. Constraints internal to the price areas are resolved by counter trading or redispatching in the regulation market. In a model of the Nordic...

I use detailed field-level data on Norwegian off-shore oil field production and a semi-parametric additive model to control for the production profile of fields to estimate the effect of oil prices on production. I find no significant evidence of a concurrent reaction of field production to oil...
