Costa Rican utility Institute Costarricense de Electricidad has begun a 10-month long project that will increase the height of its Sangregado Dam.

ICE said it plans to increase the impervious core by 1.5 meters, strengthening the 38-year old structure and increasing the capacity of the reservoir behind it.

The reservoir feeds several hydropower plants, including the 174-MW Dengo, 157.4-MW Arenal and 32-MW Sandillal projects. The facilities combine to provide about a fifth of the country’s total power supply, according to the state-owned utility.

Hydroelectric power is ICE’s primary generating source, accounting for over 80% of its total portfolio.
