Genesal Energy strengthens energy security in the Dominican Republic

According to official data, the Dominican Republic has experienced sustained growth in energy demand in recent decades, driven by increased industrial, commercial and residential activity.

To ensure a reliable electricity supply, a robust infrastructure and systems that guarantee continuity of service, even in the face of unforeseen events, are required. Genesal Energy has designed and installed a generator set for a critical electrical substation in Guayubín.

The main objective of the project is that the substation can effectively manage the electricity coming from power stations and power plants, transform the voltage and connect to the large distribution lines that supply large areas of the country.

The importance of the genset in an electrical substation

The role of a generator set in a power substation is essential to the safety and stability of the system. Substations, as key nodes in the power grid, are responsible for the distribution of power to large regions, and a prolonged interruption in their operation could leave thousands of people without power. A generator set acts as an immediate backup in the event of failures, keeping control, protection and communications systems operational. It also ensures the continuity of critical services such as transformer cooling, plant lighting and equipment overload protection, minimising the risk of damage.

Our customer needed a solution to guarantee the supply of the substation’s AC auxiliary services. So a soundproofed generator set was designed, which can be activated automatically according to the substation’s requirements, providing the necessary energy at key moments.

The Guayubín electrical substation project is an example of how Genesal Energy provides innovative and customised energy solutions to strengthen the Dominican Republic’s electrical infrastructure. Thanks to the installation of this generator set, the substation will be able to operate reliably and efficiently, guaranteeing a continuous supply of energy at critical times and contributing to the energy development of the country.

Our Engineering Solution

Genesal Energy’s engineering team developed a soundproofed 3800mm canopy genset with a 600 litre fuel tank, tailored to the customer’s specific requirements. The genset power was customised to allow for a 350 KCM gauge connection, per phase, with terminals for a 185 mm² cross-section. In addition, the design included a control system that allows cable entry to manage multiple connections.

As the project progressed, the need was identified to install an additional 500-gallon (approximately 2,000 litres) external tank, located 10 metres from the generator set. To ensure a continuous flow of fuel, an automatic transfer system with a booster pump and solenoid valves was implemented, which involved several adaptations to the canopy and tank design.

Features

• Calculation of the necessary sections for the inlet and outlet of gases in the room.
• Automatic fuel transfer system, with maximum level buoy, minimum level buoy by gauge, transfer impulsion pump, solenoid valve to cut off or control the system, among others.
• Machining of the tank and canopy for the appropriate adaptations of the transfer.
• Oversized silencer model (-30dB).
• Engine heating system 1000W.
• 600 L fuel tank.
