GOPACS is the national platform for congestion management in the Netherlands, developed and operated by all Dutch electricity grid operators. Its purpose is to help solve capacity issues on the electricity grid by enabling market-based use of flexibility.

As demand for electricity rises and more renewable sources are added to the grid, transport bottlenecks — known as congestion — are becoming more common. While grid operators work to expand and reinforce the infrastructure, GOPACS offers tools that allow them to better match electricity supply and demand in the short term.

Through GOPACS, grid operators can activate flexibility from the market when and where it’s most needed. This is done using a set of dedicated products designed to reduce or shift local grid load. GOPACS integrates with existing energy trading platforms — such as ETPA and EPEX SPOT — so participants can offer their flexibility using familiar systems.

What makes GOPACS unique is the coordinated approach across all Dutch grid operators. This ensures that solving a problem in one part of the grid doesn’t unintentionally create issues elsewhere. By sharing data and acting jointly, operators can use market-based flexibility safely and efficiently — even in complex, meshed grid situations.

GOPACS makes it possible for both large and small market participants to contribute to grid stability while earning revenue for their flexibility. It’s a key component in the Netherlands’ approach to a smarter and more resilient energy system.
