Flexible power products can be divided into three groups. Start by seeing which group best fits your company, and then find the right product within that group. By exploring now which flexible contract types suit your business, you’ll be better prepared for the future.
You agree in advance to always provide flexible capacity at specific times. This makes your contribution predictable and ensures you know exactly what to expect. This category includes the CLC-T.
You’re only called upon when the grid is really busy. This way, you contribute when it’s needed most. The products in this group include the CLC-A, the TDTR, and the mandatory bidding contract.
You decide when to offer flexible capacity. This allows you to benefit from compensation without fixed obligations. You do this through redispatch.

Prefer independent advice or a party that takes all the work off your hands? Then consult a Congestion Service Provider (CSP) about the possibilities of flexible capacity. Not all CSPs offer the same level of support or services. TenneT’s CSP register provides an overview.
Your grid operator can inform you about all flexible contract types and products they offer. Ask your account manager about the possibilities or consult a flexibility specialist. For some products, you will also need a CSP. Your grid operator can tell you more about this.
You arrange a mandatory bidding contract through a CSP (Congestion Service Provider). The CSP manages participation in redispatch on your behalf and ensures that a bid is always submitted when congestion is announced.
Together with the CSP, you agree on aspects such as:
The grid operator then uses the mandatory bidding contract to ensure that market participation and flexibility are available when congestion is expected. You can also become a CSP yourself. The certification of CSPs is arranged through TenneT.
To arrange a Capacity Limitation Contract (CLC), you need to contact your grid operator. The contract is concluded directly between you and your grid operator.
In the case of a CLC-A (dynamic / activation-based), you will register on GOPACS as part of the follow-up process. When congestion is expected, you will receive a flex message via GOPACS (possibly through your CSP).
For a CLC-T (static / time-based), GOPACS does not play an active role.
Flexible capacity that you offer through GOPACS can often also be used in other energy markets, such as FCR, aFRR, or the imbalance market.
Good coordination is essential:
This helps prevent double use of capacity or conflicting activations.
No. Participating in flex bids through redispatch does not directly affect the order in which requests for additional transport capacity are processed. Grid operators use a fixed system for this: applications are handled in the order they are received. Taking part in flex bidding does not change that position.
What flex bids do contribute to is reducing or temporarily resolving congestion. Through GOPACS, market parties help smooth out peaks on the grid. This increases the available capacity on the network and can help relieve congestion areas more quickly.
All grid users ultimately benefit from this. In short: flex bids do not provide individual priority, but they do help make better use of the grid as a whole.
