E-Harbours Zaanstad
Introducing intelligent solutions that combine the control of energy production and consumption helps to achieve the best efficiency.

The aim of E-Harbours is to explore the possibilities for large-scale implementation of smart energy networks.

Large industrial cities and harbour areas, with a dense variety of production and consumption processes, are a perfect testing ground for smart energy concepts.

The e-harbours project comprised several business cases in Antwerp, Hamburg, Zaanstad/Amsterdam, Malmö, Aberdeen and Shetlands.E-Harbours Zaanstad or ‘Green power to heat’ was the cooperation with different stakeholders on the development of a “smart and open energy system”.

This system aims to reuse residual industrial heat for housing, hospitals, swimming pools etc.

The basis idea is to introduce balancing capacity/flexibility with the heating system.

E-Harbours Findings

Technical/Economical

  • A cost reduction of 10% by trading on the APX market is feasible.
  • A cost reduction of 20% is feasible by trading on the APX market, combined with a windturbine on the local estate.
  • Electric cars seem to be the ultimate source of flexibility (15-30%). NOTE: Although physical limitations of batteries reduce the life cycle of the batteries, caused by the number of charge- discharge algorithms.
  • Financial gains seems to be a main driver by avoiding taxes and networks costs.
  • Present energy tariff i.e. the taxes versus net energy prices hamper exploitation of flexibility.

Organisational/legislative

  • The present definition of private network avoids exploitation of renewable sources of energy other than on the local estate. Regional up scaling is thereby hampered.
  • It takes a lot of effort to change existing operational processes and habits.
  • Different organizational procedures or governance is needed to realise local owned smart grids based on renewable. Public Private Partnerships (PPP) can be a complicating solution for this type of projects.
  • Responsibilities (i.e. ownership, maintenance and operations) were divided between different organizations/departments of Zaanstad or were subcontracted activities.
  • How to better involve/embed the ICT department in future projects it is suggested to define preconditions concerning ICT-security aspects, and internal ICT-standards.

Recommendations

  • Upscaling of the Zaanstad show case with more flexible energy consumers. Opportunities at Zaanstad: integration of water pumps, combined water and energy storage, and renewable energy systems (wind and solar).

  • Aanbevelingen

  • Policy influencing for more flexible interpretation of the definition of a private net.
  • Policy influencing for more flexible tariff structure for private customers to enter the flexibility market.
  • Arrange regional and national netwerks to start exchanging best practices;
  • Embed organisational guidelines to established local owned smart grids based on integration of renewable energy in the management system. Requirements of organisations, skills, expertise, finances and capacity:
  • Make a check list of crucial information and requirements and an overview of the responsible persons within organisations to get access towards this information;
  • Characteristic of a smart grid demonstration project is that different organizations are involved. Which persons have the right competence and authority to make the needed decisions
