Industrial Backup Generators | Emergency Generator

Emergency backup generators are a sustainable solution for the power needs of your facility, providing crucial operational continuity, information security, and safety in the event of a power outage.

At Applied Power Engineering, we work with you to conceptualise a solution tailored to your needs. In partnership with some of the world’s leading generator manufacturers, our team is equipped to deliver a tailored modular solution that precisely meets your specific requirements. This includes detailed design, implementation, training, ongoing maintenance, and comprehensive after-sales support.

The backup power system is integrated with an Automatic Transfer Switch (ATS), which continuously monitors the main electrical power supply. In the event of an outage, the ATS typically detects the loss of power within milliseconds and promptly activates the generator. The generator then begins supplying electricity, which is directed through software controlled transfer switching to power critical infrastructure, lighting, cooling systems, ventilation, IT equipment, elevators, life-support systems, and essential equipment, ensuring seamless operations. Once the main power supply is restored, the ATS automatically transfers the load back to the grid and safely transitions the generator into standby mode, preparing it for future use.

When integrated into your power infrastructure, an emergency backup generator delivers several important benefits for your facility.

An high availability power supply for operational continuity: First among the benefits is continued operation or trading, which could otherwise accrue significant losses, risks, and operational bottlenecks should you unexpectedly lose access to mains power. An emergency backup generator enables critical applications, systems, and processes to function in the absence of primary power. This mitigates the risk of downtime and protects revenues, as well as supports your critical infrastructure to maintain your customer’s expected service levels.
Preserve product and avoid waste: Temperature-sensitive products are at risk of damage or spoilage if critical environmental management systems fail due to a power outage. An emergency backup generator ensures the continued operation of these systems, safeguarding the integrity of these products and mitigating potential waste and associated financial losses.
Data security and integrity: power outages pose a critical risk to the integrity of data storage and security. An emergency generator mitigates this risk by safeguarding your data and keeping storage devices, servers and other IT infrastructure operational without unexpected downtime. Uninterrupted service (which can be provided by a Battery Storage system to cover short term between mains failure and generator start) also avoids the risk of files and databases becoming corrupted due to an abrupt shutdown, ensuring clients important data storage and access continues.
Environmental protection and safeguarding: In many instances, a backup power solution is crucial for protecting the lives of customers and patients, particularly in healthcare environments, while also preventing environmental harm caused by the unexpected shutdown of critical systems such as water treatment pumps, sewage processing facilities and building environmental systems. Additionally, backup power generators play a vital role in mitigating fire risks associated with overheating in systems like heat exchangers and cooling equipment used in power generation facilities where loss of grid connection occurs.

Gas Generators:

Emergency backup generators are designed to operate either continuously or in standby mode depending on fuel availability, and the needs of the application. When active, generators can be configured to provide either stable base-load electricity or peaking power. In terms of fuel consumption, a diesel generator typically consumes around 250 L per megawatt hour (based on efficiency and load). Gas generators can be more fuel-efficient, especially when designed to use gas from renewable sources and where engine heat can be used in an environmentally effective manner. The operational cost will depend on fuel prices, the generator’s efficiency, and fuel type/quality. Please get in touch to discuss your project requirements and for our recommendations on the most cost-effective solution for your application.

One of the common barriers to organisations investing in an emergency backup power solution is the ability to recoup their initial investment. Essentially, some may not comprehend that the return on investment becomes evident in the event of a power outage. Under normal operational conditions, power outages are fortunately uncommon. However, when an outage does occur, an emergency power system typically justifies its cost rapidly by ensuring business continuity, data security, environmental safety, productivity, and other critical factors such as customer confidence and 3rd party impact. Although the likelihood of a power outage may be low, the potential impact of such an event is significant, making an emergency backup power solution a valuable investment in many critical facilities.
