At Trinidad Generation Unlimited (TGU), as part of our mission to develop positive returns for the people of Trinidad and Tobago, we are committed to extending our care to the environment in which we work and being conscious of how our operations impact that environment.
Combined Cycle (reducing our carbon footprint)
Combining a natural gas-powered combustion turbine with a steam turbine generates approximately 50% more energy using no additional fuel. The heat energy from the gas turbine exhaust which would have been wasted to the atmosphere is instead recovered using a Heat Recovery Steam Generator (HRSG) to generate steam, which is used to generate additional electrical power from the steam turbine, greatly improving overall power plant efficiency.
Another advantage is that the natural gas is less carbon dioxide-intense than other fossil fuels. This means that the generators in combined-cycle plants are one of the key power-generating technologies in the battle against climate change. These turbines’ improved efficiency means they not only consume less fuel per generated kilowatt hour, but they also emit less nitrogen oxide (fewer than nine parts per million) and carbon dioxide.
TGU is committed to maintaining all required industrial standards in keeping with our corporate responsibility. As such, we continuously monitor our noise, ambient air, effluent and stack emissions to ensure that all impacts are minimised to people and the environment.
Our commitment to environmental sustainability is also reflected in our recycling initiatives. TGU recycles a variety of waste streams including paper, glass, wood, cardboard, plastic, scrap iron, fluorescent bulbs, batteries and e-waste. We are serious about our pledge to sustain our natural resources and reduce our recycling waste. We have opened up our recycling programme to all our employees, which means that they can bring their recyclable items from home to TGU to ensure that the respective waste streams are appropriately recycled.
