When a sufficient amount of wind is available in a remote, isolated grid area, the WES Hybrid system can significantly reduce energy costs. Installed WES Hybrid turbines have demonstrated that up to 80% of energy need can be generated with wind energy.
Diesel generators are often used to produce electricity in remote areas with isolated grids. Electricity generated in this way is expensive. In addition to the high cost of diesel fuel, there are other associated costs to be taken into account, including transport and storage, and losses, for example. On top of this, diesel generators are relatively inefficient and will generate about 2.5 to 3.5 kWh from one litre of diesel. As a result, the price for electrical energy in isolated grids is high, sometimes reaching over one US Dollar per kWh.
