The YESİL Hydro Electric Power Plant (HEPP) is a grid-connected small-scale hydropower plant with a run-of-river reservoir in Sivas province, Turkey. The total installed capacity of the Project is 14 MW, comprising three 4.666 MW turbines, with a predicted electricity supply to the grid of 56.16 GWh per annum.

The project is composed of a regulator, conveyance channel, headpool and a powerhouse. The regulator consists of water inlet structure, sediment pool, hard-filled weir and gravel passage. Water will be diverted at the regulator from 1,431 meters of altitude via the conveyance channel of 8,000 m and channelled into the headpool at the 1,426 m. Through penstocks of 840 m (total), the water will be carried to the powerhouse where two vertical type of Francis turbines lie.

Social and Sustainability Benefits

This project is strongly contributing to sustainable development:

• Utilize the hydroelectric potential of Turkey to meet the increasing electricity demand and contribute improving regional energy security. 
• Increase share of HEPPs in electricity generation mix of Turkey and reduce GHG emissions. 
• Contribute to economic development by creating job opportunities during construction (72 people) and operation (13 people) phases. 
• Reduce import dependency on fossil fuel weighed electricity sector and diversify generation mix through use of local resources.
