EXECUTIVE SUMMARY
A long-term tolling agreement will give Vattenfall access to 100 MW/400 MWh of battery storage capacity from Vopak’s planned 150 MW/600 MWh BESS near Meeden, the Netherlands. The project is designed to absorb surplus renewable electricity and supply power during peak demand, with commercial operations scheduled to begin in 2028.
Companies: Vopak and Vattenfall
Agreement: Battery energy storage tolling agreement
Total BESS project capacity: 150 MW/600 MWh
Contracted capacity: 100 MW/400 MWh
Project location: Near Meeden, the Netherlands
Project owner/developer: Vopak
Tolling partner: Vattenfall
Vopak, a Netherlands-based energy infrastructure company, has signed a battery energy storage system (BESS) tolling agreement with Vattenfall for part of its planned 150 MW/600 MWh battery storage project near Meeden, the Netherlands. Under the agreement, Vattenfall will secure access to 100 MW/400 MWh of storage capacity, representing a substantial portion of the planned facility. Commercial operations are scheduled to begin in 2028.
The agreement follows Vopak’s recent investments in expanding battery storage infrastructure as part of its energy transition strategy. The Meeden project is designed to absorb surplus renewable electricity and release stored energy during periods of higher grid demand. This operating capability is intended to support electricity system flexibility and improve the balance between generation and consumption.
The planned facility will have a total power capacity of 150 MW and an energy storage capacity of 600 MWh. The agreement allocates 100 MW/400 MWh of that capacity to Vattenfall. The remaining 50 MW/200 MWh is not covered by the announced agreement, and Vopak has not disclosed any contractual arrangements for that portion.
The partnership combines Vopak’s experience in large-scale energy infrastructure with Vattenfall’s position in the electricity market. Through the tolling arrangement, Vattenfall will gain access to battery capacity that can help manage fluctuations in electricity supply and demand. The companies expect the facility to contribute to a more resilient and balanced electricity grid in the Netherlands.
Jarno Veldhoven, Vice President of Business Development BESS at Vopak, highlighted the company’s transition from conventional energy storage infrastructure toward battery energy storage solutions. He said Vopak aims to provide reliable and affordable battery systems to customers and welcomed Vattenfall as a long-term partner.
The announcement also reflects the growing importance of large-scale battery storage as renewable electricity generation expands. Battery systems can store electricity during periods of surplus generation and discharge it when demand increases. This flexibility can support the integration of variable renewable resources while enabling more efficient use of existing electricity grid infrastructure.
For Vopak, the agreement represents another milestone in developing infrastructure solutions for the energy transition. For Vattenfall, it provides contracted access to battery storage capacity intended to support electricity market operations and grid balancing. The planned Meeden BESS is expected to begin commercial operations in 2028, adding 150 MW/600 MWh of storage capacity to the Netherlands' electricity system.
