Pinarayi Vijayan inaugurates Arippara Hydroelectric plant
 
Kochi, Kerala Chief Minister Pinarayi Vijayan on Saturday inaugurated Cochin International Airport Limited's (CIAL) first hydropower project at Arippara near Kozhikode.
CIAL estimates an annual power generation of 14 million units through the plant.
The 4.5 MWp run of the river small hydro project (SHP) was awarded to CIAL by the Power Department, Government of Kerala as per the Kerala Small Hydro power policy for a lease period of 30 years. The total project cost is Rs 52 crore.

Being a run of the river project, CIAL SHP at arippara works on limited storage of water causing no adverse effect on the environment.
A 32 m wide and 10 m high check dam (weir) is built across the river to divert the water to an intake pool. This check dam helps in the storage of water for atleast 5 min.
From the intake pool the water is piped to the surge tank through a 2.8 m in diameter MS pipe. And the water from the surge tank is guided to the powerhouse via a 2.2 m diameter penstock pipe.
The surge tank helps to withstand water height variation, temporary protection and the pressure difference in the penstock? pipe. In case of emergency machine shutdown, it helps to prevent excessive water pressure (water hammering).

The diameter of the surge tank is 10m and the height is 18m. The penstock from the surge tank bifurcates into two 1.6 m diameter pipes, 10 m before the power house and reaches the two turbine units.
The power generated by the generator will be fed to the KSEB grid by under ground cable.
