Energy storage, proven in the field.
Summit Energy Systems builds microgrid and flow battery systems that cycle every day and record every data point, giving utilities, partners and investors the operating evidence they need to say yes.
// targets for the 2027 program; measured results will be published as systems come online
Utilities already know batteries work. They want evidence.
The most valuable thing we build is not a battery. It is a data-rich, continuously operating platform that answers the questions every utility, grid operator and investor asks before committing.
Proven availability
Systems operating continuously, targeting greater than 98% availability, with every outage logged and explained.
Known round-trip efficiency
Measured, not modeled. Energy in and energy out recorded on every cycle, at the cell and at the AC connection.
Known degradation
Capacity and efficiency tracked over time so long-term performance can be forecast from real data.
Known maintenance cost
Every maintenance event, part and hour recorded, building a true picture of the cost to operate.
Remote monitoring
Circuit-level metering, SCADA dashboards and remote access across every system we operate.
Safe operation
Secondary containment, automatic shutdowns and fire and gas detection designed in from the start.
Four systems, each one earning the next.
We scale step by step. Each system must prove itself before we invest in the next, larger one.
Commercial microgrid
A 20–30 kWh LFP battery microgrid with energy management, backup power and whole-site monitoring.
20–30 kWh LFPFlow battery lab
Bench-scale iron and vanadium flow cells with full instrumentation to measure efficiency and validate stack designs.
Iron + vanadiumField demonstrator
An outdoor-rated flow battery skid with SCADA and safety shutdowns, built for automated daily cycling.
1 kW / 10 kWhContainerized unit
Stack, tanks, controls, inverter and monitoring integrated into a 20-ft container for demonstrations.
5 kW / 30–50 kWhOur goal: a microgrid and a flow battery that have both cycled daily for 18 months, with every data point, outage, maintenance event and efficiency measurement on record.
Long-duration storage needs more than promising chemistry. It needs a track record. That is what we are building, one gated phase at a time, with the data to back it up.
Built to be shown, tested and shared.
Utilities & ISOs
Field performance data and interconnection experience for storage planning.
Universities
Research collaboration, test data and access to operating hardware.
Grant programs
Demonstration projects aligned with state and federal clean energy priorities.
Investors
Verifiable operating evidence behind every claim we make.
