This Amended Determination follows the approval of additional funding, period of performance, removal of teaming partners, and new project milestones to include the development of three additional Substation in a Cable for Adaptable, Low-cost Electrical Distribution (SCALED) alternating current (AC) to AC cells in addition to the development of four direct current (DC) to DC SCALED cells already in progress, with a goal to create a cohesive, all-in-one structure to replace bulky, inflexible power substations in the electrical grid.

This Amended Determination follows the approval of additional funding, period of performance, removal of teaming partners, and new project milestones to include the development of three additional Substation in a Cable for Adaptable, Low-cost Electrical Distribution (SCALED) alternating current (AC) to AC cells in addition to the development of four direct current (DC) to DC SCALED cells already in progress, with a goal to create a cohesive, all-in-one structure to replace bulky, inflexible power substations in the electrical grid. Specifically, the project team will (1) continue developing, testing, and validating a DC to DC SCALED prototype at above 99 percent efficiency and a power density level 30x the state of the art, and (2) develop, test, and validate an AC to AC SCALED prototype at greater than or equal to 98 percent efficiency.
