When we talk about generator set applications, we highlight 3 types:

Emergency or Stand by:

This is a working regime for emergency applications, that is, when there is a temporary interruption in the energy supply from the usual source (public network or utility company). The generator set, in this case, is used as a secondary source.

In this application the generator operates at variable loads without overload capacity. The recommended operating limit for the equipment is 200 hours/year.

Used in all segments of the economy.

Prime:

Applicable for variable load operations in scheduled and/or emergency services.

In this application, the generator supports an overload of 10% for 1 hour every 12 hours, with the operating limit being 1000 hours/year.

Prime mode is commonly used when the company chooses to use the generator during Peak Hours. During this period, the kWh from the generator becomes cheaper than that from the public network, resulting in savings to the client. After empirical studies, savings of up to 30% in electricity costs were noted when using the generator set during peak hours (3h/day, working days).

Continuous (COP):

Also known as Base Load, it is used in situations where there is a need for continuous energy supply.

It is recommended for places where the generator is the main source of energy, where there is no local utility. Examples: construction of highways, roads, mining, construction sites, among others.

This regime is applicable to constant loads for an unlimited number of hours.
