Network upgrade
A network upgrade is an improvement to the shared transmission system, such as a new line, rebuilt substation or larger transformer, needed to serve a new load or generator reliably. Unlike facilities that serve only the customer, network upgrades benefit the broader grid. Who pays for them, and whether costs are credited back over time, depends on the utility, grid operator and regulatory rules.
