Mainspring Energy Wins 1.6 GW Linear Generator Deal With AEP

Menlo Park – October 13, 2026 -- Mainspring Energy has signed a sales agreement with American Electric Power (AEP) to supply up to 1.6 gigawatts (GW) of Mainspring Linear Generators through 2034, the largest linear generator procurement to date.

AEP orders first 190 MW tranche for delivery from 2027

AEP has already purchased an initial tranche of 190 megawatts (MW). Deliveries of that first batch begin in 2027, while the remaining capacity under the agreement would be supplied over the period to 2034.

HARTING Joins NVIDIA MGX With 800 VDC Power Whips for Vera Rubin

HARTING Joins NVIDIA MGX With 800 VDC Power Whips for Vera Rubin

Espelkamp – October 12, 2026 -- HARTING Technology Group has joined the NVIDIA MGX ecosystem as a power system component provider for the NVIDIA Vera Rubin NVL72 platform, supplying power whips that span the shift from 480 VAC to 800 VDC data center architecture.

HARTING supplies two power whips covering both MGX power generations

Power whips are cable assemblies that distribute power from the building to each rack. For the 3RU 110kW power shelf of the Vera Rubin NVL72, HARTING provides a 100A/480VAC power whip. For the move to 800 VDC, it offers a next-generation 157A/800 VDC DC-DC power whip that connects the power infrastructure to the compute rack.

Rising compute density forces data centers to handle significantly more power in tighter spaces while maintaining reliability, efficiency and scalability. That puts new demands on the connectivity systems that feed AI infrastructure.
