customers highly
recommend Stem
“Stem provides major savings and reduces the amount of time we spend managing energy. Installation, coordination with our utility and permitting were seamless.”
Tom Harkenrider
Chief of Operations at Soka University
The timing of energy use has never been more critical.
Peak rates are rising, time-of-use periods are moving, and solar policies are in flux – leaving you exposed. But most organizations don’t have the flexibility, speed, or staff to manage energy around-the-clock.
Energy costs in Southern California have been out of control. The savings from Stem have actually turned the situation around. With limited resources, it’s great to know our operation is secure going forward.
