Governor in Service Requirements

Governors:

• What do they do?

Wh th d d?• Why are they needed?

• What if they are out of service?

Slide 36

Governor in Service Requirements

Governor in Service• If a Generation Resource is On-Line, its turbine

governor must remain in service and be allowed to respond to all changes in system frequencyespo d o a c a ges sys e eque cy

• A Generation Entity may not reduce governor response i di id l G ti R d i b lon an individual Generation Resource during abnormal

conditions without ERCOT’s consent unless equipment damage is imminentg

Slide 37

Governor in Service Requirements

RequirementsR E titi t d t li bl d• Resource Entities must conduct applicable governor speed regulation tests on each of their Resources

Although governor speed regulation tests are conducted by the Generation Entity the QSE is responsible for reporting

Slide 38

Generation Entity, the QSE is responsible for reporting information to ERCOT

Governor in Service Requirements

The QSE must immediately report the following events to ERCOT:ERCOT:• Whenever the governor of a Generation Resource is

blocked while the Resource is operatingblocked while the Resource is operating• Any short-term inability of a Generation Resource to supply

governor response • If a Generation Resource trips off-line due to governor

response problem

Slide 39

QSEs must also supply governor status logs to ERCOT upon request
