The Scottish Isle of Eigg is still not connected to the power distribution grid located on the mainland 16 kilometers away. The approximately 100 inhabitants have been operating their own stand-alone grid since 2008. They successfully converted their power supply, stepping away from diesel and now generate power using virtually 100% renewable energy sources. The SMA hybrid off-grid system equipped with an installed renewable power generation capacity of 166 kilowatts integrates solar, wind power, hydropower and a storage battery. If this is not sufficient, two diesel generators are used as a backup. This provides sustainable and economical electrical power around the clock. Energy costs have dropped more than 60 percent since the conversion.
