In Bogotá Columbia the Columbian Chamber of Infrastructure" had installed two C800 Capstone micro turbines units. This is the first co-generation and tri-generation project in South America.
The units operate in stand alone mode with an energy demand of 500 kW.
The Capstones micro turbines were installed at the rooftop of the building which was possible because of light-weight and the lack of vibration.

Originally the project was designed so that the micro turbines would run in parallel with the grade and offset the electricity costs of the building and recuperate the heat to generate the air conditioning. However the were issues with getting the permits so eventually they decided to remain completely off the grid and as a consequence they are in complete control of their power costs.

We have exhaust energy from the C800 is captured and pumped to a heat recovery unit that produces hot water and with the hot water at 90 degrees celsius we take that water to an absorption chiller which produces 280 refrigeration tonnes that is then pumped to the air conditioning system in the whole building.

The Capstone micro turbines have been very efficient and reliable and in their first year of operation they have had a service record of 99.9%.

For South America this project is the flagship project for Capstone and has had two major benefits. One is the reduce power costs and secondly is the reduction in the environmental impact.

The system has roughly between 11,000 and 12,000 operating hours, and so far we have only have been required to do maintenance for the 8000 hours which is roughly change the air filters.

The future in alternative energy projects in South America lies with projects such as this one and Capstone are sure to have a significant role in them.
