Primary energy savings through thermal storage in district heating networks

District heating is an efficient way to provide heat to residential, tertiary and industrial users. Heat is often produced by CHP (combined heat and power) plants, usually designed to provide the base thermal load (40-50% of the maximum load) while the rest is provided by boilers. The use of storage tanks would permit to increase the annual operating hours of CHP: heat can be produced when the request is low (for instance during the night), stored and then used when the request is high. The use of boilers results partially reduced and the thermal load diagram is flattered. Depending on the type of CHP plant this may also affect the electricity generation. All these considerations are crucial in the free electricity market.In this paper, a multi-scale model of storage tanks is proposed. This model is particularly suitable to analyze the operation of storage systems during the heating season and to predict their effects on the primary energy consumption and cash flows. The analysis is conducted considering the Turin district heating system as case study. Results show that primary energy consumption can be reduced up to 12%, while total costs can be reduced up to about 5%.

Does increasing energy or electricity consumption improve quality of life in industrial nations?

Among the world's nations, per capita energy and electricity consumption is highly correlated with diverse indicators of quality of life. This is often interpreted to mean that additional energy and electricity consumption causes improvements in life quality. Prior analyses of cross-sectional data question this interpretation for industrial nations that already have high per capita energy consumption. The present analysis with longitudinal data shows that among industrial nations, increases in per capita energy and electricity consumption over the past three decades are not associated with corresponding improvements in quality of life.

Electricity consumption,electricity intensity and industrial structure

This paper describes an analysis of recent trends in industrial output and electricity consumption carried out at the Electricity Council. The analysis examines the significance of changes in industrial structure and in the intensity of electricity use within major industries using a simple arithmetical procedure. The conclusion reached is that such factors have, in recent years, had a major influence on trends in industrial electricity consumption. The importance of these factors explains why simple econometric models which describe industrial electricity sales as a function of total industrial output have proved unsatisfactory for forecasting purposes. This conclusion underlines the need to use a disaggregated approach to electricity forecasting, an approach which the electricity industry has used increasingly.     

Electricity consumption and associated GHG emissions of the Jordanian industrial sector: Empirical analysis and future projection

In this paper, an empirical model is developed for electricity consumption of the Jordanian industrial sector based on multivariate linear regression to identify the main drivers behind electricity consumption. In addition, projection of electricity consumption for the industrial sector based on time series forecasting is presented. It was found that industrial production outputs and capacity utilization are the two most important variables that affect demand on electrical power and the multivariate linear regression model can be used adequately to simulate industrial electricity consumption with very high coefficient of determination. To illustrate the importance of integrating energy efficiency within national energy plans, the impact of implementing high-efficiency motors was investigated and found to be significant. Without such basic energy conservation and management programs, electricity consumption and associated GHG emissions for the industrial sector are predicted to rise by 63% in the year 2019. However, if these measures are implemented on a gradual basis, over the same period, electricity consumption and GHG emissions are forecasted to ascend at a lower rate with low/no cost actions.
