【電力】ドイツの電気料金　世界一になってしまう　再エネ卸価格はマイナス

Electricity prices

Electricity prices, September 2020: The chart shows the price of electricity for households and businesses in over 100 countries. The prices are per kWh and include all items in the electricity bill such as the distribution and energy cost, various environmental and fuel cost charges and taxes. The world average price is 15.139 Japanese Yen per kWh for household users and 13.626 Japanese Yen per kWh for business users. The prices for households are calculated using the average annual household electricity consumption per year and for businesses, we use 1,000,000 kWh consumption per year. We do, however, calculate several data points at different levels of consumption for both households and businesses. The methodology of price collection is described on the about page.

The latest business and household electricity price data from March 2021 are available for download.

　需要量、輸出量が落ち込む中で再エネからの発電量が増えたことにより問題が生じた。一つは、卸電力価格がマイナスになる時間が増えたことだ。設備の再稼働に大きな費用が必要になる火力発電と電力の卸価格がマイナスでも固定価格買取制度（FIT）の下で決まった金額を受け取れる再生可能エネルギー設備は供給を止めないため、供給が過剰になり卸価格はマイナスになる。電力需要量が減少したため卸価格がマイナスになる時間が増えた。
