Design and construct infrastructure
$Many requirements to be balanced:• Security of supply• Safety• Minimum environmental impact• At affordable costs• Capacity• Future developments, biogas.• Resilience, threats, failure• Storage• Legislation, regulation, tax• Technology, • …
Model based scenario analysis as part of the design process
Changes only possible with high investment.

Key aspect of scenario analysis to support the design for critical gas infrastructure:
• Provide comprehensive data to support decision making process.

The Gas Distribution Network in the Netherlands
Discovery of the largest natural gas field of Europe in 1959 (Groningen Field, 100 TCF)
led to a fine mazed gas distribution network supplying industry and practically all households with gas (currently 40 TCF reserves)
Current national policy aims at strengthening sustainable gas production (biogas production) in the network

Current Situation for Gas Distribution Providers
• Responsible for gas supply (at specified pressure) to its customers
• Single gas supplier
• Constant gas quality
• Predictable gas usage of industry and households67/40 bar

New Developments for Gas Distribution Providers
• Local biogas providers feed into the network
• Variable Demand (Dynamic)• Local heat generation• Local power generation
(coupling E and G markets)
• More flexible Gas Supply Market
• Green for Grey Government Policy
• Increased Gas Quality bandwidth
• Higher uptime

• Enables real-time prediction of network behavior
• Designed for use in an operator support system,
• Enables to scenario analysis for cost effective design.
• Tested with off-line data of a regional network and a communal network
• Current developments:• Pilot implementation (2013)
• Can support war like scenarios
