EPEX control
Article 8 of 14 · Portals, costs and contractsWhat is EPEX control and how do I apply it?
Direct answer
EPEX control means that energy consumption, production or storage is planned based on EPEX day-ahead prices. The goal is to shift consumption to favourable hours or deploy production/flexibility at valuable moments, within technical and operational limits.
- Control on day-ahead prices
- Relevant for battery, CHP and charging infrastructure
- Safeguard technical limits
- First analyse profiles
Following prices versus EPEX control
EPEX prices change every hour. For companies with flexibility, that can offer opportunities. At the same time, price control requires good data, clear limits and an understanding of operational impact.
- EPEX control links market prices to consumption, storage or production.
- It only works if processes or assets are sufficiently flexible.
- Good rules are needed to safeguard comfort, production and risk.
Use
Traditional approach
Reviewing prices after the fact.
Modern approach
Planning consumption or production on price signals.
Condition
Traditional approach
Having a dynamic contract.
Modern approach
Having flexibility, rules and a technical connection.
Risk
Traditional approach
Accepting volatility.
Modern approach
Controlling within set limits.
Which assets suit EPEX control?
EPEX control suits assets whose timing is flexible, such as charging infrastructure, batteries, heat buffers, CHP or processes with planning room.
- Charge and discharge the battery.
- Plan charging infrastructure intelligently.
- Buffer heat or cold.
- Shift production processes where possible.
How do you start?
Start with consumption profiles and flexibility. Then determine which control is possible without disrupting production, comfort or safety.
- Analyse quarter-hourly data.
- Determine flexible capacities.
- Link price data to profiles.
- Define rules and limits.
