enesal Energy has provided one of Jamaica's biggest combined cycle power plant with two turnkey generators sets - the GEN1100CC and GEN2200CC gensets. The South Jamaica Power Centre, also known as the Old Harbour power plant, has proved a significant addition to Jamaica's energy infrastructure. It is a 194 MW combined cycle power plant located in Old Harbour Bay, St Catherine, Jamaica.
This facility is designed to operate efficiently using natural gas, providing cleaner and more environmentally friendly energy. The plant is a joint venture with MaruEnergy, JPSCO 1 SRL, EWP (Barbados) 1 SRL, and the Petro Caribe Development Fund, with the Spanish firm TSK completing the project. The plant's operational status was confirmed on December 17, 2023, and it has been providing clean, efficient power to the national grid since then. The plant's construction involved over 470 Jamaicans and was completed at a cost of US$330 million.
For the implementation of the genset control system, a PLC was integrated in order to manage all of the elements of the generating installation, as well as a protection relay and a synchronizer for parallel with mains operation.
According to Genesal Energy both units were designed according to the client’s needs: special sets with a turnkey service. This way, each genset is soundproof and installed in a completely adapted container which includes all of the elements requested by the client (air conditioning, fans, motorized louvres, fire detection systems etc.
Features of the system
-Power panel integrated in the same soundproof container. In the case of the Black Start set, they have Medium Voltage Switchgear.
-Recirculation and heating system for the engine’s cooling liquid in order to provide the correct temperature during engine start-up.
-Air conditioning system in the genset’s control.
-Motorized louvres.
-Fans in the engine room to keep the temperature under control.
-Superficial treatment for the container according to the ISO 12944 standard, with a C5I coating.
-Anti-condensation heater in the alternator.
-NFPA fuel tank
-Management of the genset control system and associated systems from the client’s installation through a PLC and a touchscreen.
-Protection relays and mains analyzer for the generator.
-Fire detection system integrated in the client’s installation’s detection loop.
-Fire extinction system through water sprinklers.
- The customer wanted each set to be monitored and controlled from its own control panel.
