National Grid has secured planning approval for three 400kV substations. The projects enable transmission circuits from South Yorkshire to Nottinghamshire to be uprated from 275kV operation.
-
TenneT Germany has priced a €2.6bn green hybrid bond transaction. The dual-tranche issue supports a transmission investment programme of around €67bn between 2026 and 2030.
-
Siemens Energy has delivered Hamburg’s final electrolyser array to Moorburg. The six-unit, 100MW plant is scheduled for commercial operation in 2027, with annual green hydrogen output expected at around 10,000 tonnes.
-
ArcLight is committing $1 billion to launch Anchor Point Transmission. The independently managed platform will develop, finance, own, and operate high-voltage infrastructure with utilities and cooperatives across the United States.
-
UC San Diego will test solid-state transformers for AI loads. The $8.48 million demonstration combines medium-voltage-to-DC conversion with flexible computing controls and utility planning at an operational supercomputer facility.
-
GE Vernova has launched medium-voltage UPS technology for data centres. The pre-commercial system combines power conversion, controls, and battery storage to isolate larger critical loads from supply disturbances and rapid demand changes.
-
Elia is testing conductor coatings to raise existing line capacity. Initial calculations indicate gains of approximately 11% to 15% without replacing conductors, subject to durability and field validation.
-
SynQor has expanded its military MCOTS power-protection product range further. The MCOTS-F-28-T-HE targets 28Vdc defence and aerospace systems exposed to severe voltage transients, surges, spikes, and reverse-polarity conditions.
-
Eaton and Singapore Polytechnic are expanding 800VDC engineering skills programmes. The collaboration brings emerging data-centre power architectures into technical education as higher AI rack densities increase electrical distribution requirements.
