Enabling the enterprise smart grid
Using data, analytics, and advanced energy storage, Stem technology enables businesses to meet their sustainability goals and participate in the next great revolution in energy technology. Putting storage at the edge of the grid is a fundamental shift in the way energy is delivered and consumed. When aggregated, Stem systems have the following sustainability benefits:
Enable distributed energy
Adding storage at customer sites enables the move to a decentralized grid and makes businesses more self-sufficient in meeting their energy needs.
Reduce peaker plants
Reducing spikes in electricity relieves the strain on the grid during peak times – and allows us to build fewer peak power plants.
Increase renewable energy
Smoothing the volatile output of solar systems enables the transition to far more widespread adoption of renewable energy.
Storage allows us to put more solar on the grid – and it helps during moments of peak demand. That means a cleaner mix of energy and fewer peak power plants.
60% of a typical utility bill is connected to the timing of energy use.
No matter how efficient your building, you’re still exposed to expensive time-based costs like demand charges and time-of-use rates.
Optimizing the timing of energy use requires going beyond human intelligence. You can’t monitor energy consumption and current prices all day long, or act quickly enough to reduce costs when prices suddenly spike. You need a way to automate this process.
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.
Stem uses UL-certified energy storage systems from the highest quality Tier 1 suppliers such as Tesla, Panasonic, and LG Chem. They have been thoroughly vetted and tested for safety and performance by independent third parties. Stem’s systems are available in multiple sizing configurations, indoor or outdoor, to match customers’ individual energy needs and building footprint.

Expand sales opportunities
Adding storage to solar projects allows you to deliver a comprehensive energy management solution that addresses both energy and demand charges. Increase project value and maximize revenue by offering a broader range of services to your customers. This may include adding storage to a proposed PV project, offering standalone energy storage to sites where solar does not make sense or offering energy storage to your customers’ sites that have existing PV.
As new incentives and value streams emerge, it becomes increasingly complex to maximize returns while ensuring program compliance. So complex, in fact, that realizing the full value of solar + storage is only possible with artificial intelligence. AI-powered controls enable energy storage to deliver a range of new value streams for solar projects – from reducing demand charges, to future proofing against changing rates, to capturing more value from the Investment Tax Credit. Storage also opens up new opportunities for customers to earn revenue through demand response, wholesale markets, and other utility programs.
Largest Storage Network
Stem’s network of 900+ storage systems creates virtual power plants that allow customers to access new market opportunities. Stem has dispatched its network more than 1,000 times to generate grid revenue for customers.
With over 900 projects – more than all other providers combined – and 300 unique customers across diverse industries, Stem has developed deep expertise in commercial energy storage. Since 2012, Stem has captured data from projects on a one-second basis and storing terabytes to Stem’s cloud to feed Athena’s machine-learning algorithms.
Battery hardware alone adds little value—unlocking the value of energy storage requires Artificial Intelligence (AI). Stem’s Athena, the first AI for energy storage, delivers more savings, higher project value, and rock-solid protection against changing rates.
Stem is committed to helping our partners succeed with storage. We have made significant investments to build the most capable platform for deploying storage in the industry, and we share these capabilities with you through the Stem Partner Network. We offer a range of support services to fit your unique needs and priorities, and we do not compete with solar partners in the marketplace.
