Four Types of Generator Power Ratings
ISO-8528-1:2018 Classifications
When choosing a generator for your project, understanding the concept of the various power ratings is critical to ensuring that you choose the right generator for your specific needs.
ISO-8528-1:2018 is an international standard for generator ratings that provides a clear and structured way to categorize generators based on their capacity and performance level. The standard categorizes generator ratings into four main categories, each designed to address different operational requirements: Continuous Operating Power (COP), Prime Rated Power (PRP), Limited-Time Prime (LTP), and Emergency Standby Power (ESP).
Incorrect use of these ratings can result in shortened generator life, voided warranties, and in some cases, terminal failure. Understanding these categories will help you make informed decisions when selecting or operating a generator.
1. Continuous Operating Power (COP)
Continuous Operating Power (COP), is the amount of power that a diesel generator can consistently output during extended periods of continuous operation. Generators with a COP rating are designed to run continuously at full load, 24/7, for extended periods of time without degradation of performance, which is critical for locations that need to rely on generators for power for extended periods of time, such as power for residents in remote areas, power for construction on sites, and so on.
Generators with COP ratings are typically very robust and have built-in features that help manage the wear and tear associated with continuous operation. These units are designed to be durable and can handle high demands without requiring frequent maintenance. If your operation requires 24/7 power without fluctuations, a generator with a COP rating will be your best choice.
2. Prime Rated Power (PRP)
Peak Rated Power, is the maximum output power that a diesel generator can achieve under specific conditions. This value is usually derived by running the test at full power for a short period of time under ideal environmental conditions, such as standard atmospheric pressure, specified fuel quality and temperature, etc.
PRP power is one of the most important indicators for evaluating the performance of a diesel generator, which reflects the generator’s ability to work under extreme conditions. These units are designed to handle higher pressure levels than ordinary commercial generators and are equipped to provide efficient and reliable service under a wide range of conditions.
3. Limited-Time Prime (LTP)
Limited-Time Prime (LTP) rated generators are like PRP units, but are designed for shorter periods of continuous operation. The LTP rating applies to generators capable of operating for a specific period (typically no more than 100 hours per year) at full load. After this period, the generator should be allowed to rest or undergo maintenance. LTP generators are typically used as standby power or for temporary projects that do not require continuous operation.
This category is typically used when a generator is needed for a specific event or as a backup during a power outage, but is not required to run continuously for an extended period. Examples of LTP applications include industrial operations that require occasional heavy loads or outdoor events that require power for only a few days at a time.
4. Emergency Standby Power (ESP)
Emergency Standby Power (ESP), is an emergency power supply device. It is a kind of equipment that can quickly switch to standby power and provide continuous and stable power supply for the load when the main power supply is cut off or abnormal. Its main function is to ensure the normal operation of critical equipment and systems in emergency situations, avoiding data loss, equipment damage, production interruption and other problems caused by power outages.
Generators with ESP ratings are not intended to operate for long periods of time and their performance under load is limited. They are designed for short-term use and often require shutdown to prevent overheating or excessive wear. It is important to understand that ESP generators are intended as a power source of last resort, not as a primary or long-term solution.
Whether you need a generator that can run continuously (COP), handle variable loads (PRP), run for a limited time (LTP) or provide emergency standby power (ESP), understanding the differences will ensure you choose the best generator for your application.
