Energy management systems (EMS)
We partner with a variety of energy management system (EMS) providers in the industry. GridVest can help you navigate which EMS may be best for your application and to pair with your battery system.
Battalion Energy
Battalion Energy provides an integrated EMS and optimization platform for energy storage, solar + storage, and microgrid projects. Its software suite combines real-time monitoring, dispatch optimization, asset management, and API-based integrations to support complex distributed energy applications.
Built for developers, EPCs, and asset owners, Battalion focuses on flexible system integration, market participation, and streamlined operations across both front-of-the-meter and behind-the-meter storage projects.

EnergyBoom
Wattchop Battery Management Service
The WattChop Battery Management Service is designed to give owners clear answers to two things: whether the system is performing, and how much it's saving.
EnergyBoom sizes the system during pre-development, then operates it using a tariff-smart algorithm. When a utility changes its rate structure, the algorithm is updated remotely so the optimization stays aligned with current rates rather than becoming outdated. Performance and savings are visible daily through the WattChop Mission Control dashboard. The system also functions as a microgrid controller, so it can continue powering the site during a grid outage.

Elexity
EMS Site Controller
Elexity's EMS platform pairs a site controller and whole-building energy meter with an AI-driven decision engine that adapts daily to grid prices, solar generation, and building load. It optimizes across demand charge management, TOU, microgrid, and grid services use cases, and its Load Control integration re-shapes HVAC and EV charging in concert with the battery to drive up to 50% more savings. Ideal for C&I on-grid and microgrid applications from 100 kW to 1 MW.
