BUFFALO GROVE, IL, Sep 28, 2026 – Siemens and Voltus have integrated Voltus’s energy monetization platform with Siemens building-side controls and services. The new combination lets Siemens load control customers enroll in virtual power plant (VPP) programs, which pay for automated cuts in electricity use.
The package pairs the Siemens Peak Demand Limiting (PDL) service, part of the Siemens Energy Load Optimization (ELO) portfolio, with the Voltus platform. PDL reduces peak demand charges and shifts energy use patterns. VPP enrollment lets a site reduce power automatically when a utility or grid operator sends a signal. The integration runs in the cloud.
Siemens targets large energy-using buildings with complex equipment and operations: commercial real estate, higher education, and state and local governments.
“Through our partnership with Voltus, our customers can now have a holistic PDL solution that enables both utility demand charge reduction and participation in demand response programs while protecting occupant comfort and indoor conditions,” said David LaTour, U.S. Head of Sustainability Portfolio, Siemens Smart Infrastructure USA. “Additionally, this low-cost, automated load management approach can help improve energy management, automate response to grid events, and provide visibility into building performance.”
“Large loads, electrification and aging infrastructure are putting enormous strain on the grid, and that’s creating an opening for commercial buildings to be part of the solution,” said Marissa Galizia, Senior Director of Partnerships at Voltus. “Our integration lets buildings deliver more reduction during an event, and do it more reliably, which means more value for customers and the grid for every megawatt enrolled.”
