Small wind energy systems that are connected to the electricity distribution system are called grid-connected systems (on grid). A grid-connected wind turbine reduces the power consumption from the utility company and can be used for lighting, appliances, electric heat etc. When the wind system produces more electricity than required, the excess is sold to the utility company. Whenever wind powering is insufficient, the grid system fills the gap.
The grid connected applications are implemented successfully in countries that have introduced an incentive plan for renewable energy. The incentive plan may include subsidies on installation, net metering option, and subsidized Feed-In Tariffs (FIT) otherwise known as renewable energy payments.
Calla Glory Grid Tied Wind Turbines including EG30kW, EG50kW which can work under on-grid circumstance without an extra inverter which is different from regular wind turbine generator system.
