- Generators who produce energy
- Transmission & Distribution Providers who carry the power to consumers; and
- Retailers who buy electricity on the wholesale market and resell it to local consumers
Austin Energy (AE) is within ERCOT but since it is a municipally-owned utility it has not had to open its local area to customer choice and retail competition. AE is still fully integrated in that it operates generation transmission and distribution.
AEs generation transmission and distribution and retail service are combined together into a single entity and the residents of that territory do not have a choice for their retail service. AEs generation competes with private wholesale generators to sell energy within the ERCOT grid.
The PUC regulates AEs wholesale transmission network when it is used to carry energy to other load serving entities like retail providers but AEs distribution and retail operations are exempt (for the most part) from PUC control. Instead since AE is a department of the City of Austin and therefore a governmental institution it is regulated" at the local level through City Council rate ordinances and its operations and practices are set by City authorities.
Periodically Austin Energy performs an accounting of its revenues and expenditures and presents a proposal to update the rates it charges in order to cover all of its claimed costs and adapt the rates to changing conditions. This process is known as a rate case" and Austin Energy began just such a rate case in January 2016 with an expectation of final rate determination by the Austin City Council on August 29 20161.
This rate case is based on revenues and expenditures from September 1 2013 through September 30 2014 known as the test year."
Austin Energy revenues come from three sources:
- Energy sales on the wholesale market
- Wholesale transmission sales and
- Rates paid by retail customers
- Austin Energy now sells all of the energy it produces to ERCOT in the same fashion as its private competitors.
- As a result Austin Energys production and its retail customers consumption have been entirely decoupled.
- The amount of power produced by Austin Energys power plants goes up or down based on how much money it can make by selling it to ERCOT and is not based on how much power Austin Energy retail customers are consuming.
Table 1
In the test year Austin Energy spent $784 million to produce energy which it sold to ERCOT. Outside of energy purchased for retail use this represented 64 of AEs costs.
The obvious next question is... How much revenue did AE receive from those sales?
