The Power Plant is located in the Magdalena River’s middle valley, in the district of Puerto Olaya, municipality of Cimitarra (Santander), approximately 5 km from Puerto Berrío (Antioquia). It has an installed capacity of 300 MW.

It was a gas-fired simple-cycle plant in its first stage, and it began commercial operation in March 1997 with 200 MW, generated by two units (100 MW each). The conversion to a combined-cycle came online in November of 2000, with 100 MW from a steam turbine, giving a total of 300 MW.

The plant's conversion from simple-cycle to combined-cycle allows it to take advantage (by means of a steam cycle) of hot gases escaping into the atmosphere during the gas turbine's combustion process. This process increases the plant's efficiency by 50%, as no additional fuel is required to generate 100 MW. This process increases the plant's efficiency by 50%, as no additional fuel is required to generate 100 MW.

The plant is connected to the National Transmission System through a 230 kV transmission line that is 8 km long. It connects ISAGEN's Termocentro substation to ISA's Primavera substation.

Energy generated using a combined-cycle system is referred to as clean technology because:

  • It uses very clean fuel like natural gas.
  • It increases the plant's energy efficiency and saves fuel thanks to the use of high-temperature gases to generate additional electricity in the steam cycle.
  • It decreases the temperature of the gases escaping into the atmosphere (low NOx burners).
  • It uses water efficiently by using a closed cooling circuit with a cooling tower, while at the same time preventing the direct discharge of hot water into the Magdalena River.

The plant has a system to operate using natural gas or liquid fuel.

Our environmental management

The environment in which we build our generation projects and operate our power plants comprises three dimensions: biotic (fauna and flora), physical (water, air and soil) and social. Whenever we carry out activities, we consider the relationship between these three dimensions, and commit ourselves to comprehensive environmental management that includes the identification, assessment, prevention, correction, mitigation and offsetting of negative environmental and social impacts, while also seeking to reinforce any positive impacts, thereby complying with current and applicable environmental regulations.

We prepare the relevant environmental impact assessments and environmental management plans, and we always adhere to the precautionary principle, i.e. if there is any doubt regarding the effect that an action or activity on our part could cause, we do not move forward with it. We carry out this exercise in all our power plants and generation projects' areas of influence, and we implement development programs, understanding each region's characteristics and facilitating participation by the communities.
