Average full (including capital, operation and maintenance costs) annual heating costs in a 2 standard family house with 180 m of floor surface are compared for various heating systems under the Polish economic conditions. The compared heating technologies comprise water to water and ground loop...

Control power (regulating power, balancing power) is used to quickly restore the supply-demand balance in power systems. Variable renewable energy sources (VRE) such as wind and solar power are often thought to increase the reserve requirement significantly. This paper provides a comprehensive...

This paper investigates to what extent unregulated local monopolies attempt not to evoke the introduction of a formal price regulation by conforming to customers’ and authorities’ expectations. It is argued that utilities can meet expectations by setting prices that imitate neighbours’...

As global fuel reserves are depleted, alternative and more efficient forms of energy generation and delivery will be required. Combined Heat and Power with District Heating (CHP-DH) provides an alternative energy production and delivery mechanism that is less resource intensive, more energy...

Austria aims at increasing its share of renewable energy production by 11% until 2020. Combined Heat and Power (CHP) plants fired by forest wood can significantly contribute to attaining this target. However, the spatial distribution of biomass supply and of heat demand limits the potentials of...

This paper tests for market power on the market for biofuels, employing a statistical model and making use of the idea of Granger causality. We use a panel data set of plant specific input prices and quantities of wood chip covering 91 Swedish district heating plants 1990-1996. If quantity...

Through analysis of the orientations, conflicts and challenges of recent energy–climate policy in Stockholm, this paper interrogates how energy and climate become (translated as) a set of issues which come to matter in the local urban arena for different social and political interests....

В статье проанализировано состояние отрасли теплоснабжения, определен круг основных проблем, изложены рекомендации по реформированию отрасли как...

Intermittent renewable energy sources (RES) are increasingly used in many energy systems. The higher capacity of intermittent RES increases the importance of introducing flexible generation units into the electricity system balancing. Distributed district heating plants with combined heat and...

In many countries, the electricity supply and power plant operation are challenged by increasing amounts of fluctuating renewable energy sources. A smart energy system should be developed to integrate as much energy supply from fluctuating renewable sources and to utilise the scarce biomass...
