Transition to net metering from 1 August 2026
What will change?
From 1 August 2026, electricity producers will transition to net metering. This change affects electricity producers who generate electricity, for example, using solar panels.
Under net metering, the electricity generated and consumed is calculated as a net amount for each 15-minute period.
How will the information in the self-service portal change?
After the transition to net metering, producers’ consumption history page will display the net amount of electricity fed into and consumed from the network for each 15-minute interval, instead of showing these amounts separately.
This means that, in the 15-minute interval view, only one amount will be displayed:
- the net amount of electricity fed into the network; or
- the net amount of electricity consumed from the network.
From the hourly interval onwards, producers will see the aggregated net amounts of both electricity fed into and consumed from the network.
If the network operator has not yet submitted the net metering data or if it takes longer than usual for the data to become available compared with standard consumption data, the amounts of electricity consumed from and fed into the network will be displayed temporarily. Once the net metering data has been received, the information will be updated accordingly.
Why is net metering beneficial for small producers?
Net metering makes it possible to more accurately account for situations where the electricity generated covers consumption at the same time.
If the electricity generated during a 15-minute period covers consumption, no electricity price, network charge or electricity supplier’s margin is added to that amount of electricity.
What will I see after the change?
After the transition to net metering, the consumption history view for producers will change. Instead of the separate amounts of electricity fed into and consumed from the network shown previously, the net amount for each 15-minute interval will be displayed.
As a result, the graph may show smaller amounts of electricity fed into or consumed from the network, and the applicable network charges and electricity costs may therefore decrease during periods when the electricity generated covers consumption.
Who does the change affect?
The transition to net metering affects electricity producers only. There will be no changes for electricity consumers in the way their consumption is calculated or in the way their data is displayed in the self-service portal.
Sample:
| Period (15 min) | Consumption kWh | Supply to the network kWh | Net consumption kWh | Net supply to the network kWh |
|---|---|---|---|---|
| Period 1 | 7 | 3 | 4 | 0 |
| Period 2 | 2 | 8 | 0 | 6 |
| Period 3 | 2 | 1 | 1 | 0 |
| Period 4 | 4 | 4 | 0 | 0 |
| Period 5-n | 9 | 5 | 4 | 0 |
| Total for all periods | 24 | 21 | 9 | 6 |
Net metering data are calculated separately for each 15-minute metering interval.
During each metering interval, the amount of electricity taken from the network is compared with the amount supplied to the network, and the difference is calculated. The net electricity taken from the network and the net electricity supplied to the network are then totalled separately for all metering intervals. As a result, the total net electricity taken from the network or the total net electricity supplied to the network for the period may not equal the simple difference between the total electricity taken from and supplied to the network. For example, in the period shown in the table, electricity consumption was 24 kWh and 21 kWh was supplied to the network, resulting in net electricity taken from the network of 9 kWh and net electricity supplied to the network of 6 kWh.
