CSP - Congestion Service Provider

A Congestion Service Provider (CSP) is a market party that deploys flexible capacity on behalf of one or more connected parties to help resolve grid congestion.
A CSP connects flexibility to the market and fully unburdens the customer.

What is a CSP?

A CSP manages flexible capacity, such as:

• temporary reduction of consumption
• additional generation
• energy storage (batteries)

The CSP registers this capacity with the grid operator and via GOPACS where required. For redispatch, the CSP offers this flexibility on a trading platform.

This makes flexible capacity directly available to resolve congestion.

What does a CSP do?

A Congestion Service Provider:

• identifies and manages flexible capacity at customer sites or from own assets
• handles registration with the grid operator and the market
• submits bids on trading platforms (for redispatch)
• manages control and activation when deployed
• monitors and verifies delivered flexibility
• handles administrative and financial settlement
• receives compensation and shares it (partly) with the customer

In short: the CSP takes care of the technical, contractual and administrative process end to end.

Who is a CSP relevant for?

For companies with flexible capacity, working with a CSP is often the most accessible route into congestion management.

Think of:

• industrial consumers
• battery projects
• decentralised generation

The CSP takes on the technical and market responsibilities. The customer unlocks value from their flexibility—without actively trading in the congestion market.
