Emergency Action Plan Ceyhan HPP Cascade, Operation Phase

The Ceyhan River basin is located in the Middle South of Turkey

Several hydropower plants (HPP) are located on the river. Among those, Dağdelen, Kandil, Sarıgüzel and Hacınınoğlu are operated by EnerjiSA.

In order to secure the safety of the personnel and residents in the downstream areas of the respective dams during reservoir operation, an Emergency Action Plan (EAP) was developed according to international guidelines.

Possible failure modes were analysed and assigned with defined alert types. 2D-hydrodynamic simulations of the flood waves, induced by the identified failure situations, were conducted to simulate water levels, wave propagation times and identify potentially threatened areas of the cascade.

Communication protocols were defined, and evacuation routes were established.

The implementation of the Emergency Action Plans reduced the risk of life losses in case of a failure event due to flooding.
