What's
VPP
Learn more about the business overview and social significance of VPP which has become important with the expansion of renewable energy adoption.
A Virtual Power Plant (VPP) is a system that connects and controls energy resources, such as production facilities, self-generation systems, battery storage, and electric vehicles (EVs), owned by businesses, municipalities, and other entities, distributed throughout a region. By utilizing Internet of Things (IoT) technology, a VPP operates as if it were a single power plant. Demand Response (DR), which involves reducing electricity demand, is a key component of VPPs and is particularly valuable during periods of high strain on the power supply.
E-Flow participates in the VPP business as an aggregator, responsible for monitoring and controlling these energy resources collectively.
![what is VPP illust](img/about_vpp_EN.png)
Why VPP is Necessary
In 2011, during the Great East Japan Earthquake, there was a severe strain on the electricity supply, leading to planned power outages. This event prompted a reassessment of the reliance on large-scale power plants alone for balancing supply and demand.
Fruthermore, the rising emphasis on decarbonization in recent years has led to the widespread adoption of renewable energy. However, the generation of renewable energy is susceptible to variables such as sunlight intensity and wind strength, posing challenges for maintaining a consistent power supply.
In light of these challenges, there is a growing expectation for VPPs that leverage resources on the demand side, in addition to the traditional supply-side efforts.
Energy Resources and Control Methods
In a VPP, an aggregator acts as a control center, responsible for the comprehensive management and control of energy resources, ensuring the balance of power supply and demand.
During times of high electricity demand, the aggregator in a VPP directs the reduction of operation for demand devices across different locations and the discharge of energy from storage systems. Conversely, in periods of surplus electricity, the aggregator promotes the operation of demand devices and the charging of storage systems. These actions are aimed at achieving an optimal balance by considering the size and specific attributes of each energy resource.
Methods used for controlling power supply and demand include demand response (DR) and reverse power flow (selling electricity).
![energy resource illust](img/energy_resource_EN.png)
What's Demand Response (DR)?
Refers to adjusting the electricity usage by controlling customer facilities in order to maintain a balance between electricity demand and supply.
What's Reverse Power Flow (selling electricity)?
In general, the term reverse power flow or surplus power export refers to the process of supplying excess electricity generated from customer facilities or solar power plants designed for full-scale power sales back to the power grid. If utilizing self-generation facilities or waste power generation facilities and engaging in reverse power flow, it is also possible to participate in a VPP and utilize the electricity generated through reverse power flow.
Contributions of VPP
Effective utilization and widespread adoption of renewable energy
Renewable energy sources such as solar power and wind power generate electricity that varies depending on factors like sunlight intensity and wind strength. As a result, it is necessary to utilize power sources such as thermal power generation that can adjust the output to maintain the supply-demand balance. By further leveraging the capabilities of VPP to adjust the balance of electricity supply and demand, it becomes possible to contribute to the wider adoption of renewable energy.

FAQ
Here are some frequently asked questions and their answers for your reference.
Is there any cost burden associated with using the "K-VIPs+" system, which incorporates various features?
We will provide the gateway device for connecting to the K-VIPs+ system free of charge, so there will be no cost burden on the customers for that. However, customers are responsible for providing the commercial power supply (100V) to connect the gateway device, as well as the necessary equipment (such as a computer, tablet, smartphone) to view the interface, and an internet connection.
Do I need to contract with a specific retail electricity provider in order to enter into E-Flow and demand response transactions?
You can contract with any retail electricity provider of your choice, so feel free to consult with us with any concerns.
If I receive a Demand Response notification from E-Flow, what specific actions should I take?
After receiving our notification (usually 3 hours prior to the start), please activate the pre-contracted demand response facilities or equipment and keep them controlled for a period of 3 hours. (Please note that you may be requested to participate in demand response up to a maximum of 12 times per year.)
What happens if E-Flow actually contacts me and I am unable to provide a demand response as contracted?
If you are unable to provide demand response as contracted, there may be a reduction in the compensation paid to you. Therefore, we carefully analyze your facilities and their operational conditions to propose a demand response plan that is feasible and realistic for you.
How much compensation can I receive?
The amount of compensation varies depending on factors such as the participation year, the capacity offered by the customer, and the method of supply. We will provide you with detailed information separately.
