A generator plays a fundamental role in the emergency power supply of a commercial or industrial entity, so it is essential to ensure your premise is fitted with a suitable and working unit. When the generator encounters problems or requires generator repairs, it is critical to find a replacement and installation service that is on-time, and within your budget.

The key to a seamless and successful process is to plan ahead and engage the services of a professional technician. This approach allows for the successful generator installation and minimises the likelihood of unexpected costs and unnecessary delays. The process of replacing or installing a new generator can differ significantly; however, there are some key steps which are relevant to all units.

Scope of Work

The first step of replacing a generator is to engage the services of a professional technician that has a firm understanding of the process, including the relevant electrical, structural, architectural and civil designs. The engineer should visit your site to gain a full understanding of the premise and to identify any factors that will influence the project. This on-site visit will help determine the generator location, fuel source location, electrical room location, any required electrical upgrades and identify any other pertinent issues.

Load Study

Generators are the ideal way to avoid the excessive disruptions and costs of a power outage; however it is essential to ensure your unit is capable of servicing your specific needs. If you choose a generator that is too small, your essential appliances and critical systems may not work during a power outage. Overloading your generator may also damage your generator or any of the devices connected to it. A generator that is too large for the load will eventually lead to a carbon build up in the engine, known as wet stacking, which can cause power loss or damage to the generator.

A load study on the circuits requiring power during an outage is the most effective way to determine your specific load requirements. Many engineers will also need this information to custom design generator for you, and such designs are required in some regions to secure a generator permit.

If your entire premise requires service during an outage, your electrical utility supplier can often provide a monthly summary of your kW usage, which also includes peak kW at particular points throughout the month. This information can assist with the load study, and provide a comprehensive overview of the required components of a generator.

Engineering and Design Drawings

After completing a load study and highlighting any critical features on the site, the next step is to have the architectural and engineering designs completed. This process takes into consideration the local legislation requirements, which may include emissions limitations, fuel containment, shading or structural enclosures, civil improvements, sizing restrictions or requirements, and zoning issues.

As these stringent regulations fluctuate significantly between different areas, it is vital to use a professional that is familiar with the codes relevant to your site. Having thorough background knowledge will improve cost efficiencies by expediting the permit process, reducing change costs and limiting time delays.

Installation

With completed and compliant plans, the installation of your generator may proceed. However, some cases may still require an approved permit from your local council, which can generally be arranged through your generator service provider. Selecting an operator with a thorough understanding of your particular area will enhance the efficiency of this process, as they often have an ongoing professional relationship with local government representatives, which typically assists the permit application process.

Typical Time Frame

The relevant time frame of a replacing or installing a new generator will depend on many factors, and is different for every scenario. A typical overview of time requirements is as follows:

1. Define scope – 1 week
2. Load study report – 1 – 2 weeks (dependent on site operations)
3. Design and plan completion – 1 – 2 weeks (dependent on complexity)
4. Checks/applications with relevant authorities 1 – 2 weeks (dependent on required approvals)
5. Order generator and ATS – 1 – 12 weeks (dependent on available stock)
6. Installation, start-up commissioning, final municipal sign off – 1 – 4 weeks
