About the project

• The client has developed and manages (24/7) the Azure-based platform (Azure infrastructure and integration layer) and application (.NET backend and two React frontends: Sage and MyGSB) that facilitates the trading and injection and withdrawal of natural gas in the storage.

Your responsibilities

• Sage is clients commercial dispatch and optimization system. In short, SAGE is clients advanced engine that turns commercial storage bookings into optimized, executable operations at Bergermeer. It's core functions are:
• • Dispatching: Manages the precise timing of gas injections and withdrawals.
• • Optimization: Calculates optimal schedules for capacity use, balancing technical limits, market demand, and weather forecasts.
• • Messaging: Automates communications with grid operators, counterparties, and internal teams.
• • Acts as the tech backbone linking bookings via myGSB, nominations, and field execution.
• • Integrates occupancy data, reservoir constraints, and market feeds (such as TTF prices) to optimize when to inject or withdraw, sending dispatch schedules directly to control systems via automated messages.
• MyGSB is clients proprietary, user-friendly portal where customers manage trading logistics—booking storage slots, setting up injections/withdrawals, and tracking volumes. It provides real-time insights into bookings, nominations, confirmations, and facility capacity.
