Efficiency metrics

Definition

Efficiency metrics are quantitative measures used to evaluate the performance and effectiveness of various processes, systems, or technologies, particularly in terms of energy consumption and resource utilization. In the context of smart grids, these metrics help assess how well the grid operates in delivering electricity, managing demand, and integrating renewable energy sources while minimizing waste and costs.
