Instead of constructing central energy systems,
. . . based on large fossil-fuel power plants,
. . . local grids based on renewables are the logical approach.

Alfen's, Cellular Smart Grid Platform (CSGriP),
. . . divides the central grid into many small cells,
. . . that have the ability to function autonomously.

In case of a central grid power outage,
. . . these local cells take over control.
. . . They automatically start restoring all local sources of energy supply,
. . . such as solar and wind, and
. . . distribute this energy amongst local consumers.

Once the grid balance within a cell is restored,
. . . it automatically reconnects to other cells, and
. . . quickly rebuilds the larger power grid.

Consequently, both the duration, and
. . . size of central grid power outages,
. . . are reduced significantly.

At the heart of this infrastructure is a
. . . 0.5 MW energy storage system, and
. . . a complex algorithm,
. . . used for local energy management.
It's self-healing mechanism, is based on frequencies,
. . . that sets it apart from many IT-related smart grids,
. . . that require relatively vulnerable data, and ICT connections.
