High CAPEX to electrify remote areas
Transmission and distribution grids:
– 3-phase grids (3 or 4 wires)
– 2-phase grids (2 wires)
– 1-phase grids (2 wires)
– 1-phase single-wire earth return grids (SWER)
Autonomous energy systems:
– diesel generators
– solar arrays
– wind generators
– hybrid energy systems
The high cost of 1 kWh of electricity in autonomous or hybrid energy systems:
10-20 times higher than from the grid
Some territories are not even considered for electrification by means of traditional energy transfer systems due to enormous cost
singlewire enables electrification of the
hardest to reach corners
of the globe
SingleWire competitive advantages
AFFORDABILITY
• significant decrease in CAPEX and OPEX, maintenance ease
SAFETY
• absence of emergency modes, no short circuits
• low voltage
• can work under extreme conditions: underwater, in high/low temperatures etc.
ACCESSIBILITY
• ability to supply energy to most complex and hard to reach areas
EFFICIENCY
• lower energy and voltage losses
• ability to transfer energy to more distant areas
