In the petrochemical and refining industry, turnarounds traditionally rely on generators as a primary energy source when disconnected from their usual supply. Generators have proven their value, particularly when paired with the proper support, offering a reliable solution for maintaining power during these critical periods. They are well-regarded for their flexibility and dependability in ensuring continuous operation.
However, as refineries and petrochemical plants seek to enhance the efficiency and cost-effectiveness of turnarounds, a promising new alternative is emerging: utilizing existing grid power to support essential loads, complemented by a robust electrical distribution solution. This approach can optimise energy use and streamline operations while minimizing the need for additional on-site equipment.
By integrating grid power with advanced electrical distribution systems, facilities can reduce their reliance on generators, streamline space utilization, and improve turnaround efficiency. This innovative strategy represents a forward-looking option that aligns with the industry's goals of enhancing performance and sustainability.

Why eliminate generators?
While diesel generators have traditionally served as a reliable temporary power solution in refineries, several considerations are driving the industry to explore alternative options:
- Cost considerations: Generators can incur substantial fuel expenses, and with fuel prices climbing nearly 14% in 2024, this cost can impact profitability, especially in an industry with tight margins. Exploring alternatives could help manage and potentially reduce these financial pressures.
- Maintenance costs: Generators require regular maintenance to ensure reliable operation, which can be costly. Maintenance needs include servicing engines, checking fuel systems, and addressing wear and tear. Alternatives that reduce maintenance requirements can contribute to cost savings and operational efficiency.
- Safety concerns: Generators can introduce safety challenges, such as tripping hazards from cables and exposure to exhaust fumes. Additionally, refueling involves handling fuel, which poses potential risks. Improving safety measures and reducing hazards is always a priority.
- Space utilization: Generators require valuable space on-site, and their placement can sometimes create logistical challenges in work areas. Finding ways to optimise space usage can enhance both safety and productivity.
- Environmental impact: With the industry facing increasing pressure to lower emissions, the environmental footprint of diesel generators can be a concern. Exploring greener alternatives can align with sustainability goals and improve the industry's environmental footprint.
- Operational efficiency: Generators are often sized to handle peak loads, which can lead to issues such as wet stacking and maintenance challenges. Utilizing a solution that better aligns with actual load requirements can enhance operational efficiency and reliability.
A smarter solution: Leveraging electrical distribution to access grid power during refinery or plant turnarounds
Many refineries and plants have traditionally used generators during turnarounds, often because they haven't explored other available options. However, if grid power is accessible, there are benefits to considering a different approach.
Connecting to existing grid power allows you to maintain essential processes and support turnaround loads without relying on generators. This can be particularly advantageous if grid power is readily available at your site.
At Aggreko, we specialise in designing and implementing temporary electrical distribution solutions tailored to your needs. Our solutions include switchgear, low-voltage panels, load centres, transformers, and more, all designed to facilitate seamless access to grid power.
The result? Reliable energy access, reduced emissions, and potential cost savings. It's a practical option worth considering when it aligns with your site's capabilities and operational goals.
