Welcome to Stem
The Stem system reduces peak demand charges and protects against unexpected price changes.
Commercial Energy Usage without Stem
The Problem
Usage spikes often occur during peak hours, leading to significant demand charges. Peak demand charges can double a company’s electric bill. Unfortunately, minimizing peak loads is a difficult challenge even for the most conscientious energy manager.
Existing solutions are limited
Energy efficiency measures have usually already been implemented. Energy data analytics help to understand when spikes occur, but do not eliminate them.
Energy storage is a great approach, but until now has been cost prohibitive.
The Stem Energy System
The Stem solution stores energy during non-peak hours for use during expensive peak hours, helping companies slash their energy costs. The beauty of the Stem system is that it doesn’t require behavior changes or reductions in electricity usage to achieve savings. It simply shifts when companies draw electricity from the grid, allowing them to focus on their core business.

How it works
Stem reduces demand charges. Stem integrates data from various sources and applies machine learning to provide highly precise energy usage forecasts. The system reduces energy costs by routing stored energy as needed to avoid peak demand charges. Stem's visualizations enable energy managers to understand the relationship between electricity usage and cost. See results >
