Supporting grid efficiency through optimized off-peak charging

FlexCharge is powered by WeaveGrid's DISCO platform, which provides utilities with asset-level visibility and device-level control over flexible loads. For Ameren Illinois, DISCO actively coordinates enrolled EVs to shift charging away from peak demand periods, reducing demand spikes and delivering a smarter, more energy-efficient charging experience built around customer’s daily needs. Together, these benefits help optimize energy resources across the grid and give Ameren Illinois valuable insights to shape the next generation of smart charging programs.

Built on Direct, Authorized Device Integrations

FlexCharge is available to Ameren Illinois residential customers with an eligible Tesla vehicle or a qualifying home charging station from ChargePoint, Wallbox, or Emporia, with more eligible devices coming soon. WeaveGrid connects to each device through trusted partnerships with leading vehicle and charger manufacturers, ensuring reliable, secure device control and keeping driver data private and protected.

“As EV adoption accelerates across Illinois, utilities need solutions that can reliably manage the impact of charging on local infrastructure while creating value for customers,” said Brett Steudle, Director of Utility Partnerships at WeaveGrid. “FlexCharge brings together the strengths of DISCO’s distribution-level orchestration and Ameren Illinois’ commitment to beneficial electrification. We’re proud to help Ameren give its customers a smarter, easier charging experience while keeping the grid reliable and affordable for everyone.”

“FlexCharge makes charging simple, rewarding, and impactful. As new load from EVs grows across our service territory, this partnership reflects our commitment to finding innovative, practical solutions that deliver real value. By working with WeaveGrid, we are helping Ameren Illinois customers charge smarter, supporting grid efficiency and Illinois' broader clean energy goals,” said Eric Sackett, Senior Manager of Beneficial Electrification, Ameren Illinois.

The FlexCharge program launch builds on WeaveGrid’s expanding portfolio of utility partnerships across North America, with programs spanning managed charging, battery orchestration, and virtual power plants. Recent partnerships include SolarEdge and FranklinWH, extending DISCO’s orchestration capabilities to residential batteries and home energy systems.
