Abstract :

Background and Objective: In recent decades, the improvement of living standards in developing societies has led to an increase in the demand of energy carriers (gas and electricity) in order to access more facilities and welfare. This study has been carried out with the aim of long-term energy planning in industrial cities for the establishment of CHP[1] projects, reducing energy consumption, using the heat resulting from energy consumption in different parts of production and the effect of different policies to reduce carbon dioxide. Material and Methodology: In line with the implementation of the study, firstly, the input values of different fuels in the industries and the effective factors in the consumption and heat demand in the industries were investigated based on the reference scenario, then the plans of the industries and government policies to reduce fuel consumption and the use of production heat. In line with this goal, the amount of fuel consumed in a base scenario (BAU)[2] in the existing industries in Leya industrial town (Qazvin province) was investigated during the years 2016 to 2019.    Findings: The current and future productions in the country's industries and the investigation of energy consumption and usable heat generation during the use of fuel in the country's industries were determined by the LEAP[3] model in the base scenario. Then, the alternative methods of energy saving and the use of produced heat and the use of CHP technologies have been investigated for a period of 15 years. In 1414, about 30% of electricity and heat consumption is provided by CHP. Due to the replacement of CHP systems, the consumption of natural gas in the industrial sector will increase by 3% and the price of crude oil and petroleum products will decrease. Discussion and conclusion: The result of the simulation in the exploitation of the CHP system resource usage scenario for the next 15 years (1414), by LEAP software, shows that all the primary energy carriers in Lea Industrial City will reach the reference state and in the year 1414 with a reduction of about 30% in domestic electricity consumption from the public electricity network and its production by CHP systems     4- Combined Heat and Power 5- Business as Usual 6- Lang – Rang Energy Alternatives Planning System
