FAQ

What does the Transmission Line Project Tracker cover?

It covers upcoming overhead, underground and underwater (subsea) transmission line projects worldwide, from announcement to construction. Substations are tracked on a separate sister site. Blackridge currently tracks 1,395 upcoming transmission line projects.

How much investment do the tracked transmission line projects represent?

The 1,395 upcoming projects add up to $356.4B in capital expenditure where capex is disclosed. Not every project reports capex, so the real figure is higher.

How many transmission line projects are under construction?

233 projects are under construction and 35 are in pre-construction. 954 are in planning, the largest single stage, and 84 are at contract award.

Does the tracker include HVDC interconnectors and subsea cables?

Yes. 5 of the ten largest projects by capex are subsea lines, including the Green Aegean Interconnector Phase I 525 kV and the Ionian – Tyrrhenian Backbone HVDC Transmission Line 525 KV. Cross-border interconnectors and offshore grid connections are tracked alongside onshore lines.

Which regions have the most upcoming transmission line projects?

Europe leads with 1,146 projects in or touching the region, followed by MENA (138) and North America (132). A project that spans several regions is counted in each, so regional counts overlap.

How is line capacity reported?

Each project carries its own capacity figure in the unit it was announced in: voltage in kV, transfer capacity in MW or route length in km. Because the units differ, the tracker reports capacity per project rather than as one total.
