Termoelectrica de Warnes – Power Generation

Project Summary

Project Termoelectrica de Warnes

Customer ENDE Andina S.A.M.

Application Simple-cycle

Technology Five SGT-800 units with DLE technology plus Auxiliaries and

balance of plant

Start One SGT-800 online since February 2015.

Complete Four additional SGT-800 units under construction/commissioning

to be completed mid 2015.

Challenge

In Bolivia the demand for electricity is growing due to domestic

development and to supply planned industrial park. Additional

expansions options for future development in the region has to be

considered.

Solution After a successful project “Termoelectrica del Sur” the customer

decided to further develop the electricity supply with flexible and

high efficient SGT-800 units in open cycle configuration. The

option of further extension of the power plant by adding

additional units and the option to extend to combined cycle

configuration ensures the upgradability required for future

development.

Benefits

The SGT-800 provide highest efficiencies for open cycle

operations with the option to further increase output power and

efficiency by combined cycle extension. Benefits to one of

Bolivia’s most vibrant economic zones.
