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...

We address a problem of inventory management of spare parts in the context of a large energy company, producer of oil and gas. Spare parts are critical for assuring operational conditions in offshore platforms. About 200,000 different items are held in several inventory plants. The inventory...

Our paper applies data envelopment analysis (DEA) and stochastic non-parametric envelopment of data (StoNED) to measure cost efficiency of electricity distribution companies. The data cover 123 Norwegian electricity distribution companies during 2004-2010, and the performance of these companies...

We construct a Malmquist productivity index based on stochastic non-parametric envelopment of data (StoNED) method, and we study how the distributional assumptions in the second StoNED stage affect productivity change and its decompositions. Our discussion show that the distributional...

We study returns to scale in Norwegian electricity distribution companies. The scale issue of this sector has become an important political question, and it was for instance discussed by the Reiten commission (OED, 2014) in a study about the future structure and organization of the Norwegian...

Fiscal policies are used to improve vehicle fuel efficiency and reduce CO2 emissions in the transport sector. Years of forceful reform in Norway may be seen as informative. From 2007, Norway has linked its new vehicle registration tax to CO2 intensities, later adapting it into a feebate form. We...

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...

Norway is a signatory to the Paris Climate Accords, an agreement that aims to prevent global temperatures from rising higher than 1.5 degrees. Although a small nation, Norway is the world’s 14th biggest oil-producing country and the 8th biggest producer of natural gas. According to experts,...
