The German market has seen a plunge in wholesale electricity prices from 2007 until 2014, when base futures prices dropped by more than 40 percent. In this paper we determine the fundamental components of electricity futures prices and quantify their impact on the price drop as well as on...

This paper analyzes the impact of electricity storage on the production cost of a power system and the marginal cost of electricity (electricity price) using a unit commitment model. Also, real world data has been analyzed to verify the effect of storage operation on the electricity price using...

We apply the lag-augmented vector autoregression technique to test the Granger-causal relationships among wholesale electricity prices, natural gas prices, and crude oil prices. In addition, by adopting a cross-correlation function approach, we test not only the causality in mean but also the...

Hourly demand response tariffs with the intention of reducing or shifting loads during peak demand hours are being intensively discussed among policy-makers, researchers and executives of future electricity systems. Demand response rates have still low customer acceptance, apparently because the...

Italy promoted one of the most generous renewable support schemes worldwide which resulted in a high increase of solar power generation. We analyze the Italian day-ahead wholesale electricity market, finding empirical evidence of the merit-order effect. Over the period 2005–2013 an increase of...

The Fukushima accident has influenced public attitudes toward energy sources and technologies, including not only nuclear energy, but also other energy sources. Therefore, it is worth investigating how the accident influenced public perceptions of renewable energy and its technologies, between...

In September 2010 the German government initiated a plan to shift from fossil fuels to renewable energies, with nuclear power as a bridging fuel. Following the Fukushima nuclear disaster, however, the government decided to immediately shut down almost half of Germany's reactors and phase out the...

There is clear consensus on the value of diversity as applied to energy systems, with the concept being a central reference for governments, industry and civil society organizations. Given its importance in policy debates, we have sought to explore the specification and measurement of diversity....

One of the key aspects of developing a regional renewable energy plan involves incorporating national renewable energy targets into provincial targets whilst including interim phase targets and technology targets. This paper proposes a renewable energy model based on national targets...

China has adopted targets for developing renewable electricity that would require expansion on an unprecedented scale. During the period from 2010 to 2020, we find that current renewable electricity targets result in significant additional renewable energy installation and a reduction in...
