Electric power transmission or “high voltage electric transmission” is the bulk transfer of electrical energy, from generating power plants to substations located near to population centers. This is distinct from the local wiring between high voltage substations and customers, which is typically referred to as electricity distribution. Transmission lines, when interconnected with each other, become high voltage transmission networks. In the US, these are typically referred to as “power grids” or sometimes simply as “the grid”. North America has three major grids: The Western Interconnection; The Eastern Interconnection and the Electric Reliability Council of Texas (or ERCOT) grid.
How does the solar industry prevent from having transmission problems arise when larger and larger amount of solar energy is being produced from solar farms miles from transmission stations? Additionally, how do they keep the costs of transmission down so the projects continue being viable?
