Hoddle Grid is the name given to the layout of Melbourne, Victoria, named after the surveyor Robert Hoddle, who marked it out in 1837 establishing the first formal town plan. This grid of streets, laid out when there were only a few hundred settlers, became the nucleus for what is now a city of over 5 million people, the city of Melbourne.
Diagram of an electrical grid (generation system in red, transmission system in blue, distribution system in green) An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers.
A grid applied within an image (instead of a page) using additional angular lines to guide proportions. In graphic design, a grid is a structure (usually two-dimensional) made up of a series of intersecting straight (vertical, horizontal, and angular) or curved lines (grid lines) used to structure content.

It is operated as an independent AC grid for physical reasons. [ 12 ] The Quebec Interconnection is tied to the Eastern Interconnection with four high-voltage direct current power transmission lines ( DC ties ), and with one variable-frequency transformers (VFTs) line, which isolate the unsynchronized AC frequencies of each side.
Circuit breakers and switches enable the substation to be disconnected from the transmission grid or for distribution lines to be disconnected. Transformers step down transmission voltages, 35 kV or more, down to primary distribution voltages. These are medium voltage circuits, usually 600–35 000 V. [1]
In 2013, Hilary Ballon, the curator of The Greatest Grid: The Master Plan of Manhattan 1811–2011, an exhibit at the Museum of the City of New York, wrote about the Commissioners' Plan: [I]n our fast changing world where technology is outdated in a blink and future-proofing is the gold standard, the grid has demonstrated remarkable flexibility.
