- Building Operators and Energy Managers Software


Athena by Stem helps building operators and energy managers lower costs by shifting energy use away from the most expensive times. Buy electricity when it’s affordable, use it later when it’s suddenly more expensive. Save thousands without any disruption to operations, staff time, or upfront capital.

Athena removes the complexities of managing time-based costs. She gives you the flexibility to buy energy at the most cost-effective times. Even with the ability to store energy, there are still thousands of calculations, forecasting simulations, and split-second decisions required to produce meaningful results.

People alone can't manage all of this, but artificial intelligence can. Our customers save between 10 to 25 percent off electricity bills without lifting a finger.

Athena: The brains behind the battery

A battery is only as valuable as the platform that operates it. Stem is the first to use artificial intelligence to learn, predict and optimize energy in real-time. Athena™ collects data at a rate of 400 megabytes per minute to continually fine-tune its algorithms. Athena has learned from operating systems for over 5 million hours, from processing nearly 200 million data intervals, and from running over 35 million project simulations.
