The underlying factors behind this electric power shortage include, on the demand side, i) overinvestment and overproduction in electric intensive industries such as steel and aluminum, ii) growing penetration rate of household electric appliances such as air conditioners, and iii) modernization in the commercial and distribution fields in urban areas (newly built large-scale commercial facilities and convenience stores). Although demand for electric power has surged, supply side factors behind the electric power shortage include i) plans to build new electric power facilities were delayed and investment restriction measures were taken as a result of the temporary oversupply of electric power, caused by economic stagnation following the currency and financial crisis in Asia, ii) there was a restricted supply of coal that could be used as fuel (such as abandonment of small coal mines due to industrial structural reform and insufficient railway transport capacity), and iii) supply did not keep up with demand because of such issues as the decline in the operating rate of hydroelectric power plants due to water shortages, thereby widening the supply-demand gap.例文帳に追加

こうした電力不足の背景には、需要サイドの要因として、①鉄鋼・アルミ等の電力多消費型産業による過剰投資・過剰生産、②エアコン等の家電製品の普及率上昇、③都市部の商業・流通分野の近代化（大型商業施設やコンビニの新設）等があり、電力需要が急速に拡大した一方で、供給サイドの要因として、①アジア通貨・金融危機以降の景気低迷により一時的に電力供給過剰となったため、新規発電設備計画を延期し投資抑制策がとられたこと、②燃料用石炭の供給逼迫（産業構造改革による小型炭坑の閉山、鉄道輸送能力不足等）、③水不足による水力発電所稼働率の低下等の問題によって供給が追いつかず、需給ギャップが拡大したことが挙げられる。 - 経済産業省
