Grid Modernization for a Leading Caribbean Utility Provider

Client Profile: A major electricity distributor 

Location: Caribbean Region

Project Scope: Large-scale transmission and distribution system upgrade

The Challenge: Sustaining Power for 14 Provinces

A major national utility provider faced the challenge of upgrading an aging power grid to meet the surging electricity demands of a rapidly growing urban and industrial population. Operating in a tropical environment, the client required high-performance transformers that could maintain exceptional thermal stability and reliability under heavy, continuous loads.

The Solution: Custom-Engineered High-Voltage Transformers

CEEG designed and delivered a specialized fleet of eight oil-immersed power transformers engineered to the client's stringent utility standards. The technical delivery included:

• High-Capacity Units: Featuring a flagship 50MVA unit for primary substation support.

• Multi-Voltage Support: Engineering solutions for both 138kV and 69kV transmission lines.

• Enhanced Thermal Management: Optimized cooling systems designed to ensure stable oil and winding temperatures, even in high-ambient-temperature regions.

The Results: Exceptional Performance & Grid Stability

The project was a significant milestone in the region’s infrastructure development, receiving widespread coverage in local national press for its role in strengthening the local power network.

Following the installation at several key substations, the client confirmed high satisfaction with the operational results:

"The new 69/12.5kV transformers are in satisfactory service, maintaining excellent oil and winding temperatures. These units are critical to our network's reliability and efficiency."— the client

Key Impacts:

1. Network Reliability: Significantly reduced load-related stress on the regional grid.

2. Operational Efficiency: Higher efficiency ratings leading to reduced transmission losses.

3. Regional Growth: Provided the stable power foundation necessary for the continued expansion of 14 provinces.
