Reduce Costs for Co-op Members with Energy Storage
Stem offers cooperative utilities and the solar developers who serve them a turnkey solution that gets projects in the ground with lower risk and greater efficiency. Through our Athena software and our team’s extensive knowledge and expertise in delivering many innovative utility projects, we help co-ops deploy energy storage to deliver meaningful value to their members.
Proven Success in Storage Projects
with Utilities
Many of Stem’s energy storage systems are contracted to respond to utility needs. Our extensive portfolio includes more than 300 systems across Southern California that provide controllable demand response (DR) capacity to the utility; a Virtual Power Plant (VPP) that helped a Hawaiian utility successfully integrate large amounts of customer-sited solar; and a Non-Wires Alternative (NWA) project with a Midwestern utility, where energy storage is helping to delay or avoid a costlier substation upgrade.
Energy Storage Solutions for Every Use Case
Stem’s energy storage solutions are tailored to address a variety of co-op requirements – whether the goal is to integrate renewable energy, reduce capacity and transmission charges, defer grid upgrades, provide resilience to members, or earn revenues through wholesale market participation. Stem’s expert team consults with utilities and developers to analyze all possible use cases and determine the best hardware and services solution that optimizes savings, reduces costs, and mitigates risk.
Seamless Integration with Utility Control Centers
Stem supports communications protocols like DNP3, allowing for seamless integrations with utility dispatch platforms. We respond to over 20,000 utility dispatches annually, with response times as fast as 5 minutes. And Stem’s proprietary utility user platform enables utility operators to schedule dispatches with a simple user interface and provides real-time operating visibility into system status and available capacity.

Featured Project: Today’s Power, Inc.
Ozarks Electric Cooperative
This project integrates a 14MWh front of meter energy storage system with 2.7MW of solar PV to reduce wholesale demand charges for Ozarks Electric Cooperative (OEC) and provide renewable energy to multiple off-taker members. Stem’s Athena AI enables OEC to schedule battery dispatch in real time or ahead of time and monitor battery status and historical performance data.
