TenneT finds 9.1 gigawatts of unused grid capacity!

It is common knowledge that the Dutch power grid is full, so organisations looking to expand their grid connection or need a new connection are often told to wait 10 years or more. This week, however, it was announced that additional off-peak capacity has been found after all.This capacity will be allocated to organisations queuing for a larger connection via Time-Duration Transmission Rights.

Time-based transmission rights (TDTR)

Time-based transmission rights (TDTR) allow connected parties on TenneT's high-voltage grid to transmit electricity during a fixed number of hours per year, with a minimum of 85% of the time available. This applies to both off-take and import of electricity. During the remaining 15% of the time, TenneT can impose restrictions on the off-take or import of electricity, for example during expected peak moments. These restrictions are communicated to customers at least one day in advance.

The TDTR is particularly attractive for companies that can be flexible with their energy use, such as organisations with battery systems, the process industry and companies with their own emergency facilities. TenneT expects flexible grid users to save up to 65% on grid tariffs through a combination of TDTR and smart response to time-dependent tariffs.

What does TDTR mean?

Time-based transmission right means that an organisation can take no or little power from the grid during peak times, but can during the rest of the day. Organisations can get creative with load shifting and use batteries to cover these peak times. With a Battery Energy Storage System, an organisation can still remain fully operational during the hours when they are not allowed to draw power from the grid.

TDTR + ELINEX BESS & EMS = 100% capacity

During the hours when capacity is available, the battery can store the power that is not directly needed for its own consumption. This power can then be used at times when capacity should not be taken from the grid. Charging and discharging of the battery is automatically controlled by the Energy Management System (EMS).
