A capacity limitation contract with time, also called static capacity limitation, is an agreement in which a large consumer or producer commits to reducing consumption or generation at fixed, pre-defined moments.
The grid operator determines these time windows, often during peak hours of the day or year. Participants therefore know in advance exactly when to limit their capacity. In return, the company receives a fixed payment for availability and any activations during those periods.
Participation in a CLC-T provides certainty. Since the times for reducing capacity are known in advance, companies can plan and align their processes accordingly. This gives clarity on both the impact and the compensation. For grid operators, this product is valuable because it delivers predictable relief of bottlenecks, helping them plan grid investments more effectively. For companies, it means contributing to a well-functioning grid while earning a structural financial reward.
A CLC-T is suitable for companies with processes that can be regularly and predictably adjusted. Examples include production lines that can temporarily scale down, cold storage facilities that can shift operations to other hours, or solar farms that structurally reduce part of their output during peak times. This product appeals to businesses that value clarity and want to know upfront what is expected, rather than depending on uncertain activation moments.
For a CLC-T, there are clear pros and cons:
Express your interest via the website or account manager of your grid operator. Or let GOPACS support you in the registration process and required steps.
Agree on volumes, time windows, and compensation with the grid operator.
Ensure the connection is measurable and that the agreed maximum can be monitored.
The grid operator tests whether the limitations are technically feasible.
At the agreed times, capacity must be reduced.
You receive the agreed compensation (or discount) for the structural limitation.
Join congestion management and earn by using your flexibility smartly. This way you benefit from attractive compensations while contributing to a reliable electricity grid.
A cold storage facility signs a CLC-T with Enexis: every weekday between 08:00 and 10:00 a maximum consumption of 2 MW applies.
The cold storage facility adjusts its operations and programs the EMS so that the cooling units run extra before 08:00.
During the agreed window, consumption is automatically reduced to below 2 MW.
At the end of the period, the cold storage facility receives the fixed compensation agreed for the limitation.
Transport capacity is the amount of electricity that can be transported safely and reliably via the grid operator’s electricity network to and from a connection or area.
Congestion management is aimed at preventing and resolving congestion situations. It is applied when actual conditions require deviations from the planned electricity transport schedule (e-programme), resulting in a temporary local transport constraint.
A congestion situation arises when the electricity grid is required to transport more power at a given moment than is technically safe. This means there is a shortage of transport capacity.
A flexibility bid is a proposal from a Congestion Service Provider (CSP) to temporarily make flexible capacity available via redispatch on the congestion market, in order to help prevent or resolve grid congestion. A flexibility bid is a response to a market announcement and needs to include certain elements.
Flexibility is delivered at fixed, pre-agreed moments. This provides certainty and yields a fixed availability fee.
With every market request you are obliged to place a flex-bid. The income depends on market prices.
You offer flexibility whenever it suits you. Successful bids generate a fee per activated megawatt hour.
