In the fiscal year 2022, the electricity costs for homes amounted to ** Japanese yen per kilowatt hour. The electricity costs increased multiple times since fiscal year 2016, when the figure stood at ***** yen per kilowatt hours.  Competition in the electricity market remains limited The competition in the Japanese electricity market remains limited as it continues to be dominated by ten regional electric utilities. Retailers of low voltage electricity mainly sell their electricity locally to homes or small shops. Tokyo Electric Power Co., Inc., also known as TEPCO, continued to rank as the largest electric power company in Japan in terms of total assets. The electric company is known for the nuclear accident at its Fukushima Daiichi Nuclear Power Plant in 2011.  Causes for rising electricity costs After the nuclear disaster, nuclear energy was replaced by fossil fuels. Since Japan lacks domestic reserves of fossil fuels, it heavily depends on imports. Consequently, the self-sufficiency rate of primary energy decreased shortly after the disaster, causing electricity costs to rise. Additionally, in recent years, a short supply of liquefied natural gas (LNG) reinforced the price increase.

This dataset is (surplus or shortage) imbalance price in the Japanese electricity market from March 2022. The data source is here.

• After the full liberalization of retail electricity in 2016, a new system of simultaneous balancing of planned values ​​was introduced, and retailers and power generators create demand and power generation plans for each 30-minute period, dividing a day into 48 periods, and operate to match supply and demand by one hour before actual supply and demand (gate close).
• If an imbalance occurs in actual supply and demand, the general power transmission and distribution company issues a command to the power source (adjustment power) to adjust to eliminate the imbalance.
• Power generators and retailers each formulate a power generation plan and a demand plan for the next 48 periods by 12:00 the day before. Power generation plans and demand plans can be changed up to one hour before each period.
• The difference between the plan and the actual result (imbalance) is compensated for and absorbed by the power transmission and distribution company using its adjustment power.
• The person who caused the imbalance must subsequently settle the unbalanced amount of electricity with the electricity transmission and distribution company as an imbalance price.

For fiscal year 2025, the FIT price of electricity that is generated from solar energy in Japan was set at ten Japanese yen per kilowatt hour.The feed-in tariff (FIT) system is a national system under which the unit price of electricity is fixed by the country. It is designed to increase investments in renewable energy systems by providing price certainty and long-term contracts to renewable energy producers.  Solar energy is the largest renewable energy source in Japan In recent years, solar energy overtook hydropower as the largest renewable energy source in Japan. The generation capacity of solar energy continues to rise as the Japanese government made investments in solar power a priority. As the island nation strives to become carbon neutral by 2050, it aims to increase its share of renewables and nuclear power. Consequently, the share of renewables in electricity production has increased to over ** percent in recent years.  Solar energy prices keep decreasing In 2015, the government started to cut the FIT-based purchase price of electricity generated from solar energy. Since the sales price of solar photovoltaic (PV) modules has decreased as well, this resulted in a long-term decline in solar power costs. The Ministry of Economy, Trade, and Industry (METI) estimated that solar power will become cheaper than nuclear power by 2030.

In the third quarter of 2025, Bermuda had the highest household electricity prices worldwide, followed by Ireland, Italy, and Germany. At the time, Irish households were charged around 0.44 U.S. dollars per kilowatt-hour, while in Italy, the price stood at 0.42 U.S. dollars per kilowatt-hour. By comparison, in Russia, residents paid almost 10 times less. What is behind electricity prices? Electricity prices vary widely across the world and sometimes even within a country itself, depending on factors like infrastructure, geography, and politically determined taxes and levies. For example, in Denmark, Belgium, and Sweden, taxes constitute a significant portion of residential end-user electricity prices. Reliance on fossil fuel imports Meanwhile, thanks to their great crude oil and natural gas production output, countries like Iran, Qatar, and Russia enjoy some of the cheapest electricity prices in the world. Here, the average household pays less than 0.1 U.S. dollars per kilowatt-hour. In contrast, countries heavily reliant on fossil fuel imports for electricity generation are more vulnerable to market price fluctuations.
