Powering Oil Refinery Operations with a Custom 660kVA Diesel Generator

In February 2025, Target Power delivered a fully custom TB660 diesel generator to a Portsmouth-based oil refinery, supplied through our reseller, SJ Power. This heavy-duty backup power solution features a Baudouin 48M21G660/5 engine, Target branded alternator, and a bespoke 4-pole ABB 1250A circuit breaker—engineered to meet the site’s high-demand industrial machinery requirements. The generator was built and delivered within a seven to eight week timeframe.

Challenges Overcome

This bespoke build presented several engineering and installation challenges, which our team addressed with practical solutions:
 

Circuit Breaker Fitment:

The ABB 1250A 4-pole breaker, along with a custom busbar connection box, required a strategic layout to allow safe, accessible positioning. The breaker also supported load bank connection, which was essential for the client’s test and maintenance operations.
 

Noise Reduction Requirements:

Given the generator’s continuous operation, it was essential to supply an ultra-low noise acoustic canopy. Our turnkey product range offers generous internal access, making the generator easy to maintain while keeping operational noise to a minimum. You can see the 600 kVA Diesel Generator running here.
 

Large Cable Accommodation:

The client’s installation involved 240mm cable entry, so we increased the gland size to accommodate this, ensuring smooth on-site integration without requiring additional modifications.
 

Why the TB660 Generator Was Chosen

Target Power offered the client a variety of options based on budget, lead time, and specification requirements. The Baudouin-powered TB660, paired with our in-house alternator, provided the best balance of performance and value. Although budget-conscious, the solution upheld our high manufacturing standards and technical reliability.
