What is meant by an electric grid interconnection?

An electric grid interconnection refers to a network that links various electrical grids together. This interconnectedness allows for the sharing of electricity between different regions and grid operators, enhancing reliability and efficiency within the power supply system. By enabling power to flow freely across different areas, interconnections help balance supply and demand, facilitate backup during outages, and support the integration of renewable energy sources.

This concept is crucial for maintaining a stable and resilient electrical infrastructure, as it permits utilities to import or export power as necessary, minimizing the impact of local shortages or surpluses. The interconnected network also allows grid operators to work collaboratively across larger geographical areas to optimize power generation and distribution, thereby improving overall system performance.
