Grid

The network connecting electricity producers to consumers. The boundaries of the grid can be drawn differently but may include electricity generators, high power transmission wires, lower power distribution wires, and end users such as homes and businesses as well as the regulatory and market structures that impact electricity transactions. The grid is a physical infrastructure transmitting electricity and is also an economic entity that responds to supply and demand communicated through prices.
