ACER publishes today the report on unit investment
cost indicators and corresponding reference values for electricity and gas infrastructure.
The report is the result of collaborative work carried out by national
regulatory authorities (NRAs) cooperating in the framework of the Agency.

The report contains separate volumes for electricity
and gas infrastructure. In electricity, it covers overhead
lines, underground cables, subsea cables, onshore AC substations, and HVDC
converters. In gas, it cover pipelines, compressors stations, and to a lesser
extent LNG and storage facilities. The indicators and the corresponding
reference values contained in the report may be used as a reference in the
context of the Ten-Year Network Development Plan (TYNDP), to complement the
cost information provided by project promoters. They could also be used as a
point of reference in the context of the selection of projects of common
interest (PCI) and for the development of better informed cross-border cost
allocation (CBCA) decisions.

A complementary
objective is to provide transparency regarding the levels of costs of infrastructure
in the European Union, as well as the changes in these levels, in the structure
of the costs, and the role of various factors affecting the costs. For reasons
explained in the report, the indicators and the corresponding reference values
should be used with caution and must not be regarded as a substitute for the
due diligence in each instance of an existing or planned investment in
infrastructure.
