Flexibility as the new norm

We aim to encourage customers to use energy more flexibly. Doing so creates space on the electricity grid and helps ensure that access to energy can be maintained for everyone in the long term.

Opportunities for large business customers

Grid congestion can hinder the growth or sustainability ambitions of large business customers. At the same time, it creates opportunities for companies that can use energy flexibly. Technology plays an important role here, but behavioural changes are equally essential.

Steering through flexible contracts

  • Flexible contracts provide access to additional transmission capacity at times when the grid can accommodate it. This encourages companies to align their electricity use with grid availability. Such arrangements include congestion management contracts and alternative transmission rights.

  • Under a congestion management contract, a company agrees to restrict its use of the grid during peak periods. Outside those periods and when there is no congestion, the company can fully utilise its contracted transmission capacity. By 2025, this type of contract was available across almost the entire Enexis service area.

  • Blokstroom (‘block power’), an alternative transport right, offers customers additional capacity between midnight and 6 a.m., for example to charge trucks or buses. Companies have been able to contract Blokstroom since April 2025, where capacity is available. By the end of 2025, 100 organisations had done so.

  • Another option is the group transmission agreement (GTA). Under this arrangement, multiple companies share a defined amount of transmission capacity. By coordinating generation, consumption, and storage, they can use more capacity collectively than they could under individual contracts. The GTA is also a key building block for energy hubs. In 2025, we worked with other grid operators and the ACM on a draft code decision to enable group agreements. In November, the first GTA was signed in Nederweert.

Opportunities for low-volume consumers as well

Until now, most alternative solutions have focused on large business customers, as low-volume consumers were not affected by congestion in 2025. At present, grid operators maintain waiting lists only for high-volume consumers, while low-volume consumers can still be connected. From 1 July 2026, however, this will change and the waiting list will also apply to low-volume consumers. Given the size of this group and its potential to enable more flexible grid use, we are seeing a growing sense of urgency and are therefore developing alternative solutions for low-volume consumers.
