Termoflores is an existing natural gas fired power generation plan, which has been in operation for more than tens years. It is located on a highly intervened industrial zone of Barranquilla, and is currently in compliance with air, noise, wastewater, and solid waste Colombian discharge and emission standards as well as all labor and occupation health and safety regulations. The stack emissions are also in compliance with the Thermal Power: Guidelines for New Plants, included in the World Bank’s Pollution Prevention and Abatement Handbook (1998). The upgrade from simple to combined cycle of Flores II and III, will generated more energy without increasing fuel consumption, and operational measures such as water injection in Flores II, and the installation of a wet compression in Flores II and III, to reduce NOx emissions.
The key environmental, social, and health and safety impacts and risks associated with the project’s construction phase are those typically associated with construction and civil works such as increased noise and air emissions, construction solid waste and waste water management, occupational health and safety of construction workers, and risks associated to the operation and handling of heavy equipment and machinery.
In general terms, it can be stated that the environmental footprint of the operation of the plant per KWh/hour generated will be reduced, since this project involves the installation of a heat recovery steam generator (HRSG) on each of the two existing gas turbines (upgrade from simple to combined cycle), thus generating 169 MW more without significant additional fuel consumption. The key environmental, social, and health and safety impacts and risks associated with the operational phase are those related with increase in generation capacity of an already existing plant, and thus are limited to: (a) increase water use from 77 to 280 l/s, (b) increase sludge generation from the process water treatment system from 1.9 to 9.0 tons/day (wet base), (c) seventy percent (70%) reduction on NOx emissions, (d) reduction of temperature of the stack emissions (412 oC and 488 oC less for Flores II and III, respectively), (e) continued generation of air emission, noise, and industrial wastewater discharges, (f) continued use and handling of HAZMAT (e.g. lubricants, oil and greases, di-electric oils, etc) and subsequent generation of hazardous waste, (g) continued generation of domestic solid waste and domestic wastewater, (h) continued existing occupational risk to plant employees (e.g. working in confined spaces, hot conditions, heights, handling heavy equipment, etc), (i) continued/increased existing nuisances to nearby communities (e.g. traffic, noise, etc), (j) continued existing risks to nearby communities, associated to any potential accident or spill, and (k) reduction of approximately 460,000 tons of annual CO2 emissions (more electric energy produced without using significant additional gas, will be displaced other plants less efficient).
Given that this project will improve the environmental footprint of an existing power generation plan, and the incremental environmental, social, and health and safety impacts and risk can be avoided or mitigated by adhering to generally recognized performance standards, guidelines, and/or design criteria, this project has been categorized as a B operation. A condition of IFC’s investment will be that Termoflores ensures that all relevant social and environmental risks and impacts, including all issues covered in IFC Environmental and Social Performance Standards, are considered and appropriately managed. Further information about how potential environmental, social, health and safety and labor impacts and risk will be addressed by Termoflores is presented in the Environmental and Social Review Summary (ESRS) for the project.
