Abstract

This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as inputs. Electrical energy delivered per year is used in the model as output. The study offers some detailed policies to improve the efficiency of the plants. Mean technical efficiency of hydroelectric power plant in 2011 and 2010 are 62% and 53%, respectively. Mean technical efficiency of thermal power plant in 2011 and 2010 is 82% and 77%, respectively. The results of the study indicate that mean technical efficiency of thermal power plant in 2010 and 2011 is higher than efficiency of hydroelectric power plants.

Abstract [Persian]

هدف اصلی این مقاله برآورد کارایی نیروگاههای تولید برق (فسیلی و تجدیدپذیر) برای استانهای ایران میباشد. برای برآورد کارایی از روش تحلیل پوششی داده ها (DEA) استفاده شده است. شبکه DEA با چند ورودی (نهاده های تولید) و یک خروجی (تولید برق) بسط داده شده است. هزینه های سوخت (برای نیروگاه های تجدیدپذیر صفر است.)، نیروی کار و هزینه های عملیاتی به عنوان ورودی در نظر گرفته شده است. انرژی الکتریکی تولیدی در هر سال به عنوان خروجی در نظر گرفته شده است. در نهایت در این مطالعه نیروگاه های برق در کشور بر اساس کارایی دسته بندی شده اند و بر اساس سناریوهای مختلف جهت بهبود کارایی نیروگاه ها توصیه هایی سیاستی ارائه شده است.
