Potential nuclear threats to the US include high altitude blast (i.e. electro-magnetic pulse) which can paralyze the US power grid for months.

The US military has therefore initiated planning to ‘harden’ the US electrical infrastructure against such threats, as well as from cyberattack.

The development of resilient electric power for US military bases is already under way via the concept of three isolated microgrids. The military will construct completely isolated grids for military bases, called a “MiliGrid”.

The trend is to eliminate all overhead power lines, use distributed under-ground DC distribution systems and utilise all electric power sources (i.e. wind, solar and high-speed turbine generators).

They will also utilise use energy storage, establish energy priority and neutralize hotel and other load lower priority loads. For other critical regions a “MuniGrid” will be implemented. It will be similar as the MiliGrid but for critical non-military application. Finally, a MacroGrids will be established for regional electric power distribution requirements.

The US government plan is for a complete reworking of the US national electrical grid, transitioning to underground DC cable transmission. Resonant Link will be in position to use its unique capabilities. It has the LV, MV and HV converter and transformation capabilities, which combined with high efficiency, is ideal for military power systems and utility applications.

The Resonant Link technology for these applications is protected by the US patent 8,824,179.
