![Concrete example: Pulp and Paper Industry
Mechnical
Pulp Lines • Overcapacity: 10%
• High Consumption: 30 MW
• 5 Lines of ON/OFF Process
• Ramp up/down constraints 1H
• High Supply Chain constraints
Paper
Machines
• No overcapacity
• Medium consumption: 6 MW
• No stops allowed (high cost to
start-up and production loss)
CHP
• High production of electricity: 20 MW
• Steam Storage ( 10H of steam
demand)
• Highly flexible to switch production

The document discusses energy flexibility valorization, focusing on how industries can identify, extract, and use their energy flexibility in demand response management. It emphasizes the importance of understanding constraints, market opportunities, and advanced analytics to optimize energy costs and resources. Concrete examples from the pulp and paper industry are provided to illustrate different flexibility optimization strategies across various market contexts.
