EnergyHub, the grid‑edge flexibility arm of Alarm.com Holdings, announced on December 2, 2025 that it had agreed to acquire Resideo Grid Services, a demand‑response aggregation and program‑management provider. The deal adds Resideo’s portfolio of roughly two dozen utilities and 2.5 million distributed energy resources—thermostats, electric‑vehicle chargers, batteries and other DERs—to EnergyHub’s Edge Distributed Energy Resource Management System (DERMS) platform.
The acquisition brings EnergyHub’s client base to more than 120 utilities that collectively serve over 55 million customers, a figure that combines EnergyHub’s existing 120‑utility footprint with Resideo’s 24‑utility portfolio. The combined DER inventory of 2.5 million assets gives utilities a single, cloud‑based platform to orchestrate a broader mix of assets for virtual power plant (VPP) operations, positioning EnergyHub to capture a larger share of the rapidly expanding VPP market, which reached 37.5 GW of capacity in 2025.
EnergyHub’s segment already accounts for roughly 30 % of Alarm.com’s SaaS revenue and is growing at 20‑25 % year‑over‑year. By integrating Resideo’s demand‑response capabilities, EnergyHub can offer utilities a more comprehensive solution for grid flexibility, strengthening its competitive moat against other DERMS providers such as KrakenFlex, Schneider Electric’s AutoGrid, and other incumbents. The acquisition also deepens Alarm.com’s footprint in the energy‑management space, aligning with the company’s strategy to diversify beyond residential security into commercial, international and energy‑management markets.
Financial terms of the transaction were not disclosed. The deal is expected to accelerate EnergyHub’s revenue growth and enhance its ability to leverage its cloud‑based platform across new verticals, reinforcing Alarm.com’s long‑term growth trajectory. The acquisition is a significant step in Alarm.com’s broader effort to expand its portfolio and capture emerging opportunities in the VPP and DER markets.
The announcement underscores Alarm.com’s commitment to building a diversified, cloud‑based ecosystem that spans security, energy, and other verticals, and signals confidence in the continued expansion of the VPP market and the value of integrated DER management solutions.
