Transmission infrastructure reference costs

Transmission infrastructure reference costs

A key role for network development

Setting up an appropriate and transparent cost estimation plays a key role while developing new networks. Using the reference values of specific costs can significantly facilitate many processes, increase their credibility and enable reliable comparisons at European level.

Pursuant the TEN-E Regulation (article 11(7)), in 2015 the NRAs cooperating in the framework of ACER established a set of unit investment costs indicators and their corresponding reference values for both gas and electricity infrastructure sectors.

These indicators and reference values are now widely applicable. They can be used for preparation of the TYNDP, the PCI selection, for developing CBCA decisions and many other analyses. In electricity infrastructure, unit investment costs have been established for:

  • overhead lines

  • underground and  subsea cables

  • onshore AC substation

  • transformers

  • HVDC converter stations.​​

What's the role of ACER?

ACER provides a cooperation framework for NRAs to establish and publish the set of indicators and corresponding reference values.​

Transmission infrastructure reference costs

What does ACER say?

​The ACER report on the unit investment costs and corresponded reference values in electricity (2015) proved to be a useful tool for project assessment. However, given the evolving market and technology conditions, its relevance is declining over ​​​​time. Nevertheless, ACER recommends this activity to be regularly repeated as largely beneficial for different stakeholders.​
