Renewable energy Dissemination through control of power supply and demand Ministry of the Environment August 25, 6:38
The government aims to make solar and other renewable energy a “main power source”, but the problem is that the amount of power generation varies greatly depending on the weather and the balance between supply and demand tends to be disrupted. The Ministry of the Environment will include 7.5 billion yen in the budget request for next year's budget proposal and will spread the system to control the balance between supply and demand.
The government's “long-term strategy” for advancing global warming countermeasures has set the goal of “renewing main power sources” by 2050 for renewable energy such as solar and wind power.
However, the amount of power generated by solar and wind power varies greatly depending on the weather, and if there is surplus electricity, the balance between supply and demand may be disrupted, resulting in a large-scale power outage.
For example, in Kyushu, the amount of solar power that can be generated is increasing at a rate of 50,000 kilowatts every month, and since October last year, “output control” has been implemented to temporarily stop power generation.
Because it is necessary to eliminate such instability in order to make renewable energy a “main power source”, the Ministry of the Environment decided to work on the spread of a system that controls the supply and demand balance of electricity.
The system connects building storage batteries and electric vehicle charging devices to the Internet, and remotely stores and charges when there is a surplus of electricity.
The Ministry of the Environment intends to subsidize one half of the cost for businesses that have introduced such systems, and will include approximately 7.5 billion yen in the budget request for next year.
