Power Generation – HV Power Transformers CCGT Power Plants
Operation of CCGT Power Plants:
Flexible cycling of CCGT plants of paramount importance.
It entails frequent start-ups and shutdowns of conventional units, twice a week on average.
Units may be stopped approx. 4,000 hrs/yr.
Cost of Transformer Energization Transients:
Uncontrolled energizations of step-up transformers cause system-adverse transients : inrush currents, voltage dips.
When the units are stopped, the step-up transformers are left energized to avoid these issues.
Resulting no-load transformer losses = 600MWh* /year/unit
* Estimate : 350MVA - 330kV transformer / unit.

Power Generation – HV Power Transformers CCGT Power Plants – Example : Sorgenia - Italy
Flexible cycling of CCGT power plants
Frequent start-ups and shutdowns of conventional units, twice a week on average
Each unit stopped approx. 4000h/year
Est. costs of no-load transformer losses = 600MWh or approx. $40k / year / unit
SynchroTeq on two (2) units per plant : => Switching off/on two (2) transformers / plant => Cost-savings approx. $80k / year / plant
Asset preservation: elimination of inrush currents and stress on transformers and C/B
Frequent power transformer switching with no impact on HV power grid
