Frequently asked questions

What is an energy management system?

An energy management system is software, often paired with meters and controls, that monitors, analyzes and optimizes energy use across buildings, sites or equipment.

What is a smart grid?

A smart grid is an electricity network that uses digital communication, sensors and automation to monitor and manage the flow of power between generation and consumers.

Why does energy storage matter for the grid?

Storage lets electricity be saved when supply is high and used when demand is high, which helps balance variable renewable sources such as solar and wind.

How do large energy users source renewable energy?

Common options include power purchase agreements (PPAs), green tariffs from utilities, on-site generation and energy attribute certificates. The right mix depends on location, load and contract terms.
