Siemens Energy to Supply 119 SGT-400 Cores for Dynamis' Hypermobile Power Packages

Siemens Energy will supply 119 SGT-400 gas turbine cores to Dynamis Power Solutions for the company's DT18 hypermobile power packages, according to a Sept. 30 announcement.¹ At about 15 MW apiece, the cores add up to more than 1.7 GW of generating capacity.²

Deliveries will run over several years, with the first batch due in 2027. Siemens Energy will build the cores at its Lincoln, U.K., facility, which the company describes as its global center for small gas turbine manufacturing.¹ Dynamis, which designs and builds the DT18, is targeting data center operators, oil and gas producers, utilities and industrial customers that need power quickly.² The order's value was not disclosed.

A Compact Twin-Shaft Machine

The SGT-400 is a twin-shaft gas turbine offered in versions of roughly 13 MW and 15 MW, with simple-cycle generation efficiency of about 35%, according to Siemens Energy's product literature.³ Its dry low emissions combustor holds NOx below 10 ppmvd on natural gas, and the engine can switch between gaseous and liquid fuels at any load. Siemens Energy lists hydrogen capability of up to 30% by volume with dry low emissions burners.³ Hot gas path service intervals are specified at 32,000 hours, depending on the operating profile.³

Second Turbine Supplier for Dynamis

The Siemens Energy order follows an August announcement that Dynamis had ordered 76 NovaLT16 turbines from Baker Hughes, about 1.3 GW, for its DT17 package.⁴ Added together, the two orders represent roughly 3 GW of turbine capacity. Dynamis CEO Matt Crawford has said the company leads the hypermobile power market with about 2 GW of packaged power today.⁵ Karim Amin, a member of Siemens Energy's executive board, said the partnership pairs proven gas turbine technology with new deployment concepts to get capacity to customers quickly.⁵

What It Signals

Mobile packages offer a way around some of the lead time on utility-scale frames, and Dynamis is now sourcing from two OEMs to feed them. Several questions remain open: the contract value, whether the orders are firm or reservations, and how Lincoln's output will be scheduled around the company's other orders.

For readers on the service side, a fleet this size is also an aftermarket story. Units redeployed between sites will log hours on varying duty cycles, the kind of operating profile that drives inspection and overhaul schedules.
