Structural steering during peak moments

CSC-T: Capacity steering at fixed moments

A CSC-T (capacity steering contract with time or static capacity steering) is a contract with the grid operator in which companies adjust their electricity consumption or production at fixed moments to reduce congestion on the electricity grid.

CSC-T at a glance

  • A CSC-T is a contract with the grid operator for capacity steering at fixed moments
  • You actively adjust consumption, generation or storage within agreed time windows
  • You increase or decrease power to relieve the electricity grid
  • You retain your transport capacity, while deploying flexibility in a targeted way
  • A CBC-T provides financial compensation, helps reduce waiting times for new connections, and helps prevent congestion

What is a CLC-T?

A capacity steering contract with time (CSC-T) is a contract in which a large consumer or producer agrees to actively increase or decrease electricity consumption or production at fixed moments. The goal is to relieve the electricity grid during peak periods.

The grid operator determines the time windows for capacity steering, usually during periods when the electricity grid is heavily loaded.

Participants therefore know in advance when adjustments are required. During these periods the company adjusts consumption or generation according to the contract terms. This creates additional capacity on the grid exactly where and when it is needed.

In return, the company receives a fixed compensation for making flexibility available and deploying it during the agreed periods.

Why enter into a CSC-T contract?

Participation in a CSC-T delivers immediate value: a fixed fee and full predictability. You know exactly when to adjust and can align your operations accordingly.

For example:

  • shifting production to different times
  • temporarily increasing or reducing electricity consumption
  • adjusting generation or using storage

This allows you to optimize your energy use, avoid disruptions to your operations, and create a stable revenue stream.

At the same time, you help relieve the electricity grid at peak moments—without being structurally limited in your transport capacity.

For businesses, this means: maximum control, predictable revenues, and smart use of flexibility.

Who is CSC-T suitable for?

CSC-T is suitable for companies that can temporarily adjust their consumption or production without interrupting their operations.

Examples include:
• industrial companies that can shift processes in time
• data centres or cold storage facilities with flexible energy use
• energy installations that can ramp production up or down
• companies with energy storage or an energy management system (EMS)

The product is particularly interesting for organisations that can actively steer their energy use but prefer predictable moments of activation.

Is CSC-T suitable for your organisation?

A CSC-T comes with clear advantages and considerations.

Predictable: time windows and conditions are known in advance
Financial certainty through a fixed compensation
Flexible way to help solve grid congestion
Full transport capacity remains available outside the steering periods
Business processes must be controllable
Additional energy management or EMS may be required
Adjustments must be made during the agreed time windows
The contract contains binding obligations

CSC-T in 6 steps

1. Register with your grid operator or GOPACS

Indicate your interest via the website or account manager of your grid operator. GOPACS can help guide you through the registration process.

2. Draft a contract with your grid operator

Together with the grid operator you agree on volumes, time windows and compensation.

3. Technical setup

Ensure installations and the energy management system (EMS) can steer power during the agreed periods.

4. Validation by the grid operator

The grid operator verifies that the steering is technically feasible and measurable.

5. Active participation

During the agreed time windows the company adjusts consumption or production according to the contract terms.

6. Receive compensation

You receive the agreed compensation for making flexibility available and deploying it during the agreed periods.

CSC-T in practice

Situation

A cold storage facility enters into a CSC-T agreement with its grid operator. On every working day between 14:00 and 16:00, the company temporarily increases its electricity consumption by 1 MW. Between 18:00 and 20:00, it reduces its electricity consumption by 1 MW.

Steering

Between 14:00 and 16:00, the facility runs its cooling systems at a higher capacity to increase electricity consumption by 1 MW. In addition, it pre-cools before 18:00 to build up sufficient cold storage. During the agreed time window, fewer compressors are running, and the load automatically decreases by 1 MW.

The energy management system (EMS) ensures that consumption stays within the agreed bandwidth. The metering chain continuously verifies whether the control actions comply with the contract.

Result

During off-peak hours, the load on the connection increases; during peak hours, it decreases. This creates grid capacity exactly when and where it is needed.

At the end of the contract period, the facility receives the agreed compensation for providing flexibility.

CSC-T Glossary

Transport Capacity

Transport capacity is the amount of electricity that can be safely and reliably transported via the grid of the grid operator to and from a connection or area.

Congestion Management

Congestion management is the set of measures used to prevent and resolve congestion on the electricity grid. When a local transport constraint occurs, due to deviations from the planned schedule (e-programme), grid operators actively adjust to keep the grid safe and balanced.

Congestion Situation

A congestion situation occurs when, at a specific moment, the electricity grid needs to transport more power than is technically safe. There is temporarily insufficient transport capacity, and the grid reaches its local limit.

Flexibility bid

A flexibility bid is a proposal from a Congestion Service Provider (CSP) to temporarily make flexible capacity available via redispatch on the congestion market, helping to prevent or resolve grid congestion. A flex offer follows a market announcement and consists of several standard components.

Other forms of flexible power

Fixed times contract
_

Flexibility is delivered at fixed, pre-agreed moments. This provides certainty and yields a fixed availability fee.

CLC-T

Contract on request
_

Flexibility is only requested when the grid is at risk of overload. You receive a fee per time you are called upon.

CLC-A
TDTR

Mandatory bidding
_

With every market request you are obliged to place a flex-bid. The income depends on market prices.

Mandatory bidding contract

Voluntary bidding
_

You offer flexibility whenever it suits you. Successful bids generate a fee per activated megawatt hour.
