Voltus connects distributed energy resources to wholesale electricity markets, generating income for businesses while building a more resilient and flexible grid.

DER platform enabling a flexible grid

Voltus works with commercial and industrial customers, as well as distributed energy resource (DER) aggregators, to generate significant savings by shifting energy consumption during times of stress on the grid. The company uses simple, cost and risk-free programs to enable owners of DERs to monetize assets through wholesale energy markets. The Voltus platform empowers the shift towards cleaner distributed energy resources while modernizing the grid to be more flexible and resilient.

The energy transition depends on a technology platform to enroll and orchestrate distributed energy resources across real time energy, capacity, and demand response markets, as DERs enable global electricity grids to decentralize, decarbonize, and digitize, while delivering less expensive, more reliable, and cleaner power. As DER deployments accelerate in the coming years, asset owners and aggregators will seek access to wholesale power markets in order to unlock grid flexibility and better economics, and Voltus is the leading software technology platform monetizing these distributed assets.
