Effective January 1, 2001, the current GRC rates for both property tax components are graduated based on the annual generation of a station as follows:
|Total Annual Generation||GRC Rate|
|Up to and including 50 gigawatt hours (gWh)||2.5%|
|Greater than 50 and up to and including 400 gWh||4.5%|
|Greater than 400 up to and including 700 gWh||6.0%|
|Greater than 700 gWh||26.5%|
Every station owner benefits from the lower rates on the gross revenue from the first 700 gigawatt hours of annual generation for each station. The GRC water rental charge rate is fixed at 9.5% of a station's gross revenue from annual generation.
