Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The …
… in a business model which offers Svenska Kraftnät an increased volume of electricity production through free capacity in CHP plants. This stabilizes the national energy system when the electricity production from renewable energy sources is low. Free capacity occurs due to more …
En jämförande studie om elevers val på Teknikprogrammet respektive El- och energiprogrammet.
… is to understand the factors that are affecting students at the Technology and Electricity- and energy programs in their choice of studies and vocation. The study is a comparative case study and quantitative method has been used in the form of questionnaires. The result shows …
… cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is …

… to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most …
Påverkan av ett ökat antal elbilar på ett halländskt elnät
… increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most …
Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
… University was Monica Jakobsson. Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting …
… for this parameter in question. Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is …
… result was that the metro based on the worst-case scenario (marginal electricity) had such good results. It had one result that was the highest of them all, SO x . In the overall standings (cost for the society, sek/pkm) though it was only beaten by the other electricity mixes …
… a lot of electronics that needs battery power to work. In addition to that electric propulsion systems have gotten more popular lately, which further increases the demand for high battery capacity. The batteries used are mostly lead-acid batteries and to get the most out of the …
En studie som undersöker möjligheter och hinder i utvecklingen av det svenska elsystemet
Distributed, renewable generation-units and more efficient use of electric power,demands a developed electric grid. This grid is often referred to as the ”Smart Grid”. This future electric system rise expectations among actors in the existing electricmarket. International …
The goal of this paper is to provide a model for a sustainable electricity system to an island, in the Pacific Ocean near the equator.The method which has been used is to model supply and demand of electricity in the computer program Stella, through the creation of a dynamic …
Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet
… market shares. This Master’s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is …
