The power of energy flexibility

Stem’s software-driven energy storage 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.

“This steps ahead of other technologies because energy is always going to cost more at certain times than others. If you can charge the battery when costs are low and deploy it when costs are high, that gives you a hedge.”

Hear from Soka University’s Chief of Operations about how Stem automatically optimizes the timing of energy use.

Soka University of America’s Tom Harkenrider (Chief of Operations) and Scott Collins (Director of Operations) share their experience working with Stem and why they chose intelligent energy storage to save on utility demand charges. Soka University is a leader in sustainable operations and a recipient of the APPA Award for Excellence.

60% of the 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.

Trying to address these issues manually is inefficient and time-consuming. 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 an automated way to respond to time-variable energy pricing without disrupting operations.

“This is one of the best projects we’ve done on the campus.”

Director of Operations at Soka University

Timing is everything.

Overview

Intelligent energy storage removes the complexities of managing time-based costs. It gives you the flexibility to buy energy at the most cost-effective times. Figuring out the ideal time to buy energy requires constant monitoring, hundreds of calculations, and split-second decisions.

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.

“With a very small investment, easy installation, and hardly any effort on our part, Stem’s service lowered energy costs right away to add immediate value.”

Automatically save on energy costs

Every facility has an opportunity to access major savings by using less energy during expensive times. But even the largest enterprises can’t afford to devote staff time to tracking every upcoming rate change, monitoring constantly fluctuating peak usage, scheduling operations around variable pricing and responding to changing price signals in real-time.

Stem’s intelligent platform learns and anticipates the timing of your energy use, and combines that knowledge with information about your energy rates, time-variable pricing, upcoming rate changes, demand response opportunities, weather forecasts, and real-time energy use.

With a grid-connected intelligent system, you can optimize the timing of energy use automatically, saving thousands each year, with no impact to operations.

“With a very small investment, easy installation, and hardly any effort on our part, Stem’s service lowered energy costs right away to add immediate value.”

Defend against rate changes

The rise of renewables and distributed energy resources is transforming the electrical grid, causing rapid changes to energy rates. At the same time, extreme weather conditions such as the polar vortex – which tripled businesses electricity prices in January 2014 – are increasing in frequency. And grid infrastructure is aging, increasing maintenance costs that are ultimately passed through to customers. Rate changes are becoming more frequent as a result of the changing energy ecosystem, leaving facilities exposed to variable and unpredictable costs.

Intelligent energy storage responds to these changes automatically, minimizing your exposure to financial risk.

“We needed a solution that automatically responds to changing loads, rates and rules. With Stem, we will save on energy for years to come.”

Advance your sustainability strategy

Impress your senior leaders and customers with a sustainability initiative that will help you qualify for LEED points, improve the value of solar investments, and support a more sustainable, resilient grid for your community. Energy storage is easy to sell internally: it’s a simple, plug-and-play installation that complements existing projects, integrates seamlessly, and requires no upfront capital.

Plus, as part of Stem’s network, you’ll receive compensation for supporting the grid.

“This program is part of an overall strategy and culture in our company to be sustainable and save money on utility costs. Stem is an opportunity to showcase both goals.”

Operations Manager at Macerich

Enhance renewable investments

Stem stores and optimizes solar and other onsite generation so that you get the highest value from those clean electrons. Continue to use solar power in the evening when prices are rising. Protect against costly demand spikes when clouds block solar output. Store your extra renewable energy for later to maximize emissions reduction. Future-proof your investment from potential policy changes that could cut your compensation. With Stem, you can use your solar production on your schedule to maximize the value of your investment.

“I’m proud that we have the lowest energy usage by a university in Southern California. We want to keep that trend going, and Stem is our next step in that direction.”

Director of Operations at Soka University

See what you’re saving

Stem’s service comes with a reporting tool that provides complete transparency into your system’s operations. With real-time visibility and periodic reports, you’ll always know how much you’re saving. Results are fully auditable and easily verifiable through the software.

“Stem didn’t overpromise. After more than a year of being operational, my Stem system is actually generating about 20% more savings than what was initially projected, which I can easily track within the software.”

The brains behind the battery

A battery is only as valuable as the platform that operates it. Stem’s industry-leading operating system uses artificial intelligence to learn, predict and optimize the timing of your energy use in real-time. Stem has over 3.5 million system operating hours under its belt, has processed nearly 200 million data intervals, and has run over 35 million project simulations. Data that we collect at a rate of 400 megabytes per minute is continually funneled into our AI to fine-tune its algorithms.

“Stem’s software is best-in-class. It tells the battery when to store and discharge power, responds to demand response opportunities, and reduced our exposure to changing utility rates.”
