A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers . [ 1 ]
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations , electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers.
When power outages occur, you may hear officials use unfamiliar words as they explain the situation or provide updates. We explain a few common terms.
Texas electricity generation by type, 2001-2024. This is a list of electricity-generating power stations in the U.S. state of Texas, sorted by type and name.In 2022, Texas had a total summer capacity of 148,900 MW through all of its power plants, and a net generation of 525,562 GWh. [2]
Welsh HVDC Converter Station is an HVDC back-to-back station connected between the J. Robert Welsh Power Plant and the Oncor Electric Delivery substation at the Monticello Steam Electric Station in Titus County, northeastern Texas. It went in service in 1995 and it can transfer a maximum power of 600 megawatts.
The Texas Interconnection is one of the three minor alternating current (AC) power grids in North America. All of the electric utilities in the Texas Interconnection are electrically tied together during normal system conditions, and they operate at a synchronized frequency operating at an average of 60 Hz.
In short, an ISO operates a region's electricity grid, administers the region's wholesale electricity markets, and provides reliability planning for the region's bulk electricity system. Today's RTOs do the same thing with an added component of greater responsibility for the transmission network, as established by the FERC.
