Generator Installation in South Africa: General Principles

Installing a diesel generator in South Africa is a technical process, combining regulatory compliance, environmental considerations, safety measures, and adherence to code. Since generator installations are inherently dangerous, meticulous and experienced professionals are required to provide safe and compliant installations. The overview of the key steps and considerations provided in this article are not intended to be a “do it yourself” guide but to emphasise the importance of consulting generator installation professionals who will be familiar with local regulations and provide a code-compliant installation.


Breaking Down the Rules: Ensuring Compliance in Generator Installations

One of the most important steps in generator installation, whether commercial, industrial, or residential, is complying with the rules and regulations of local authorities, regulatory bodies, and homeowners’ associations. National and municipal building codes, environmental regulations, and safety standards must also be complied with to deliver a legal and safe installation. Part of providing a compliant installation is choosing an appropriate location for the generator to be situated. Factors such as easy access for maintenance, generator noise, and environmental impact need to be considered. Compliance with zoning regulations and land-use policies is essential to avoid legal complications.

Depending on the size and nature of the project, conducting an environmental impact assessment may be required. This assessment helps evaluate and mitigate potential environmental effects, ensuring responsible and sustainable installation practices. Coordination with the local municipality or Eskom may be necessary for a legal connection to the electrical grid. Adhering to regulations regarding connection, synchronisation, and islanding protection of the generator with the grid is critical.

South African regulations provide guidelines that must be followed, but it’s crucial to know that different municipalities may have distinct laws outlined in their bylaws regarding generator installations. Specific bylaws may have been established to regulate how Eskom supplies electricity to households and to manage alterations to the existing electrical infrastructure. Some neighbourhoods, complexes, and estates may enforce specific regulations on generator use and installation. Some estates have a total prohibition on the use of generators at all. Even smaller residential generator installations need to be undertaken by qualified electricians so that they are safe and do not cause fires or constitute a shock hazard to the homeowner (SANS 10142-1:2003). A Certificate of Electrical Compliance (COC) should be issued to the homeowner on completion of the installation.


Logistical and Environmental Considerations

Large industrial and commercial generator installations may require civil or structural engineers to design and specify concrete slabs or footings onto which the generator will be placed. It is not advisable and may be against building codes to place a generator on a gravel bed. The generator needs to be kept level and the vibrations produced during operation must be accommodated. Large industrial generators are typically secured to a permanent structure. Concrete is the industry standard for sites with normal soil conditions.

The thickness and size of the concrete pad are controlled by soil composition and several other geographical considerations. The weight the concrete pad needs to withstand (heavier loads require reinforcement) is used by the engineers to design an appropriate structure.

Establishing a safe and compliant fuel storage facility is an obvious imperative. Regulations regarding fuel-storage capacity, safety measures, and environmental protection must be followed. Ensuring a reliable and continuous fuel supply is vital to keep a generator running smoothly. In bigger installations, the fuel storage area should be easy to access for refueling vehicles and measures should be in place to mitigate any accidental fuel spillage.

Even the most efficient generators produce exhaust gases which are toxic and present a potential health hazard. Installing appropriate emission control systems is, therefore, necessary to protect personnel and comply with air quality standards and regulations. An environmentally responsible generator installation will include regular air quality monitoring and emissions reporting.

Generator installations must also adhere to local noise regulations and reasonable steps should be taken to minimise the impact of generator operation on the occupants of surrounding businesses and residences. This means that careful consideration of the noise level and its possible impact is crucial during site selection.

Noise pollution refers to unwanted or disruptive sounds that unreasonably interfere with people’s daily activities. In legal terms, South African legislation distinguishes between “disturbing noise,” which is objectively defined as a scientifically measurable noise level, and “noise nuisance,” a subjective measure which covers any noise disturbing or impairing the convenience or peace of an individual. Both types of noise are considered illegal under the Environment Conservation Act (73 of 1989) and the Noise Control Regulations.

Generators are noisy and a potential source of noise pollution but luckily, noise-reducing measures such as silent-run enclosures are available to mitigate the noise produced. Both backup and standby generator installations must comply with the South African National Standard (SANS 10142-1:2003).


Generator Installation and Safety

Safety measures include several steps specific to generator installations and some more general applications. Implementing safety measures includes fire-protection systems, emergency shutdown procedures, proper site safety signage, and training of key on-site personnel. Occupational health and safety regulations also need to be adhered to in order to ensure a secure operating environment. Adherence to the South African National Standard (ISO SANS 8528 series of standards) is essential for any generator installation in the country.

In certain environments, installing smoke and carbon monoxide detectors and keeping them operational would be prudent even where this is not mandatory. End users do not need to delve into every detail of the legislation themselves to ensure compliance with health and safety regulations and the other relevant requirements, provided they employ professional generator installation specialists. Having a compliant generator installation remains the responsibility of the end user.


Testing and Commissioning a Generator Installation

Thorough testing and commissioning of the generator system are essential to ensure its proper functionality and compliance with specifications. The testing and commissioning give the installers the opportunity to check that the generator meets the agreed-on performance and safety standards. At the end of commissioning, the generator is formally handed over to the end user with all the necessary project documentation. The documentation will include warranties and a comprehensive maintenance plan to ensure the ongoing reliability and performance of the generator. Regular maintenance is key to preventing breakdowns and ensuring continuous operation.

The evolving regulatory landscape underscores the importance of staying informed and seeking local expertise to ensure a compliant and efficient installation.
