2025 proved that Virtual Power Plants (VPPs) are a cornerstone of modern grid operations. Record heat, surging demand, and aging infrastructure pushed the limits of the power system — and virtual power plants rose to meet the challenge.

EnergyHub and our utility partners delivered flexibility at scale that matches the capabilities of conventional generation and sets new benchmarks for reliability and customer value.

Delivering scale that matters

EnergyHub operates one of North America’s largest and most reliable cross-DER VPP platforms, with:

• 3.4 GW+ of dispatchable flexibility
• 2.5 million+ devices under management
• 150+ utility clients

And in 2025, those capabilities delivered real results:

• 3,140 events dispatched, an increase of more than 25% compared to 2024
• 38.3k+ MWh of load shifted  (enough electricity to power the entire state of Vermont for about 2 and a half days)

These numbers represent much-needed capacity, measurable reductions in system costs, and tangible impact during critical grid events. In 2025, that impact helped utilities maintain reliability during unprecedented stress. As more utilities leaned on VPPs to manage increasingly complex grid conditions, program enrollment scaled right alongside system needs.

A year of record demand for flexible capacity also drove record participation. EnergyHub’s “100K Club” expanded again, with seven of our utility clients now managing more than 100,000 enrolled devices — a sign that control rooms across North America are benefitting from cross-DER, grid-scale flexibility.

Keeping the grid reliable during extreme conditions

2025 included record-setting days for grid stress. During the summer “heat dome,” VPPs delivered predictable flexible capacity and dependable performance. 

On June’s hottest day, EnergyHub dispatched 130 MW of load shed during Ontario Independent System Operator’s annual peak, protecting the grid when it mattered most.

EnergyHub also brought Dynamic Load Shaping (DLS) to additional clients, improving customer experience while delivering longer, more predictable events.

• Delivered consistent load shed throughout the event while maintaining per-device performance within 10% of a standard demand response (DR) event. (Fig. 1)
• Achieved 50% more flexibility in the third hour compared to a standard DR event. (Fig. 2)
• Reduced hour-to-hour variability and avoided costly snapback.

Figure 1 – Standard DR events show variable performance and snapback peaks, while Dynamic Load Shaping delivers flat, predictable load shed across the event window.

Figure 2 – Dynamic Load Shaping pilots delivered flat, predictable load shed across one-hour and three-hour events, reducing variability and snapback compared to standard DR.

Turning EVs into grid assets

EV adoption continued in 2025, with electric vehicles making up nearly 10% of all new vehicles sold. EnergyHub continued to evolve our EV managed charging solutions, delivering a frictionless driver experience without sacrificing flexibility or control.

• Acquisition of Bridge to Renewables (BTR) — opening opportunities for more EV OEMs to participate in utility programs while providing simple, engaging charging experiences that optimize cost and emissions for drivers.
• Partnership with GM — expanding the list of vehicles eligible to participate in utility managed charging programs nationwide..
• In-app Tesla enrollment — cutting enrollment time by 70%, reducing friction for drivers.
• Protecting grid assets from EV‑driven overloads — reducing EV charging peaks by up to 50% through multi‑level distribution optimizations without compromising the driver experience. 

Together, these advancements help utilities ensure continued distribution grid reliability as they prepare for the next wave of EV-driven load growth.

Expanding utility capabilities through EnergyHub’s Resideo Grid Services acquisition

EnergyHub’s acquisition of Resideo’s grid services business combines the capabilities of two industry leaders. For utilities partnered with Resideo, this integration brings expanded capabilities – including the ability to manage multiple types of DERs – and new opportunities to strengthen flexibility programs.

Here’s what this partnership unlocks:

Greater scale and utility impact

The acquisition significantly expands EnergyHub’s footprint across utilities, regions, and customers, increasing the amount of flexible load we can aggregate and manage. This added scale strengthens EnergyHub’s ability to deliver meaningful, grid-level flexibility.

More advanced grid and market services

Resideo Grid Services adds deep expertise in capacity-based demand response and ISO/RTO market participation. Combined with EnergyHub’s platform, this enables more sophisticated dispatch, optimization, and performance in wholesale energy, capacity, and ancillary services markets.

Broader device orchestration and flexibility

The combined company can integrate and control a wider range of connected devices, especially residential technologies like thermostats. This improves customer participation while enabling more reliable, multi-device flexibility for utilities and grid operators.

Unlocking more grid value with cross-DER VPPs

Utilities are increasingly tapping multi‑DER virtual power plants to deliver greater flexibility, reliability, and customer benefits. In 2025, this trend accelerated. Today, 21 utilities on EnergyHub’s platform run cross‑DER programs, including:

• 10 combining two DER types
• 11 integrating thermostats + batteries + EV/EVSE

The path ahead

In 2026, the question isn’t whether virtual power plants belong on the grid — it’s whether they can perform like the conventional resources utilities already rely on.

That shift requires the industry to be more precise about what a “good” VPP looks like. Scale alone isn’t enough. VPPs must be available year-round, follow operator-defined schedules, and provide timely, accurate telemetry.
