What is the main function of a demand meter?

The main function of a demand meter is to measure the energy delivery rate, particularly in terms of demand for electrical power. Demand meters gauge the maximum amount of energy consumed over a specific period, typically a 15-minute interval. This measurement helps utility companies determine the peak load requirements of a customer, which can influence billing and energy distribution strategies.

By monitoring the demand, utilities can ensure they maintain adequate energy supply, plan for capacity, and manage their resources effectively. This is critical for both operational efficiency and cost management, allowing for a more sustainable approach to energy delivery.
