Updated on May 25, 2016
Starting in March 2016, we began installing smart meters with bidirectional metering capabilities that measure the amount of electricity supplied and the amount of electricity purchased (received) in cases where solar Power generation equipment etc. have been installed and a low-voltage supply-receive contract has been concluded.
In this regard, we would like to inform you as follows about the current limit for reverse power flow when a bidirectional smart meter with a current limiting function is installed.
1. Current limiting function for reverse power flow in smart meters with current limiting and bidirectional metering functions
Traditionally, when installing solar Power generation equipment, etc., the ACL is designed to operate even in the case of reverse power flow, so in many cases the supply and demand Contracted Electricity Capacity has been determined based on the capacity of the solar Power generation equipment, etc.
The newly introduced smart meters with current limiting and bidirectional metering functions are designed so that they do not limit current due to reverse power flow, so there is no need to take the capacity of solar Power generation equipment, etc. into consideration when determining the supply and demand Contracted Electricity Capacity.
2. Important Notices
- The meter capacity of smart meters with current limiting and bidirectional metering functions is 60A only.
- If Power generation equipment capacity exceeds 12kW, a smart meter with a bidirectional metering function of 120A or more will be installed, so the smart meter will not be able to limit the current.
- As usual, a current limiter (ACL) will be installed.
Current limiting for reverse power flow in smart meters with current limiting function (20KB)
Updated on Mar. 9, 2016
Starting in March 2016, we will begin installing smart meters in all areas under our jurisdiction (Note) for customers who use low-voltage electricity, such as ordinary households.
In relation to this, we would like to inform you that we have clarified how to handle low-voltage receiving meters when installing smart meters with bidirectional metering function.
- For some remote islands, the start date for installing smart meters will be decided taking into consideration the state of communication network development by telecommunications carriers. [Target areas: Oron Island, Takeshima Island, Iwo Jima Island, Kuroshima Island, Kuchinoshima Island, Nakanoshima Island, Hirashima Island, Suwanosejima Island, Akusekijima Island, Kodakarajima Island, Takarajima Island, Kuchinoerabujima Island]
1. Functions of smart meters with bidirectional metering capabilities
With its bidirectional metering function, this smart meter can measure the amount of electricity supplied and purchased (received) with a single unit.
- When carrying out wiring work and installing an instrument box, etc., please carry out the work assuming that one meter will be installed.
2. Effective date
From Monday, February 22, 2016, when applications are accepted
3. Installation costs for the receiving meter
When installing a smart meter with two-way functionality, the costs associated with installing and replacing the receiving meter will, in principle, be free of charge.
- If a solar Power generation equipment is installed on vacant land, for example, and a larger meter is required in order to connect Power generation equipment to the grid, we will charge you the additional cost.
For applications for connection contracts for solar Power generation equipment made after April 1, 2015, due to a revision of the national system, the timing for determining the procurement price has been changed from "the date of application for connection contract with the electric power company" to "the date of conclusion of the connection contract with the electric power company."
Therefore, if you wish to be eligible for the fiscal 2015 procurement price for solar Power generation equipment, you will need to receive national equipment certification by March 31, 2016 and then enter into a connection agreement with us.
The date on which the connection contract will be concluded with us (Note 1) will be sent to you by us in the "Guide to the Grid Interconnection Contract" when we respond with the results of our technical review.
- In principle, the date on which the connection contract is concluded with us is the date on which construction costs are claimed in the case of low voltage (less than 50 kW), and the date on which the connection is approved in the case of high voltage.
Under these circumstances, we are currently conducting technical studies one by one. However, we have already received a large number of applications, and depending on the grid situation, the technical studies may take a long time, so it may be difficult to conclude the connection agreement by March 31, 2016 (Note 2).
- For applications for interconnection of 10 kW or more, it is anticipated that it will be virtually impossible to conclude connection contracts by March 31, 2016, even at sales offices where applications are concentrated, including for those who have already submitted applications.
Even for applications for less than 10kW grid connection, depending on the future application situation, it may be difficult to conclude a connection contract by March 31, 2016. We ask for your understanding in advance.
Therefore, please note that even if you receive national equipment certification during fiscal year 2015, you may not be able to apply the fiscal year 2015 procurement price.
We will do our utmost to respond to technical inquiries as soon as possible, but there are some cases where it is taking a long time to complete the review, such as for systems with a high volume of applications. We apologize for any inconvenience this may cause our customers, and we appreciate your understanding.
<Reference> Steps from application to grid connection for low voltage (less than 50kW)
- The date of conclusion of the connection contract will be notified to you in the "Grid Interconnection Contract Information".
- The procurement price, start date for receipt of electricity, etc. will be notified in the "Information on Solar Power Generation Electricity Supply Contract."

On March 19, 2015, the Agency for Natural Resources and Energy published a document entitled "Regarding Procurement Prices and Equipment Certification for Solar Power generation equipment under the Feed-in Tariff Scheme for FY2015," outlining the price application rules for FY2015. The applicable conditions are as follows. We ask for your understanding and cooperation.
- For applications for which either or both of the "national equipment certification date" and "date of application for connection contract with us" fall on or after April 1, 2015, the procurement price for the fiscal year in which the later of the "date the connection contract with us is concluded" and the "national equipment certification date" (Note 1) falls will be applied.
- Since May 2, 2015, it has become necessary to obtain national equipment certification before applying for a connection contract with us, so the procurement price for the fiscal year in which the "date on which the connection contract with us is concluded" falls will apply.
- Regarding the date of connection contract establishment, there are cases where the contract is not concluded due to no fault of the power generation company, such as when our company's technical review takes a long time, so if the connection contract with our company is not concluded by the 270th day counting from the day after the application date for the connection contract (Note 2), the procurement price for the 270th day will be applied. (270-day rule)
- If you applied for a connection contract before May 2, 2015, and the application was made before the national equipment certification, the starting date for calculating the 270 days will be the day after the national equipment certification date.
- Please refer to the reference materials for specific examples of application of procurement prices.
