Vehicle-to-Building Power Market Report 2026

The vehicle-to-building power market size has grown exponentially in recent years. It will grow from $1.4 billion in 2025 to $1.71 billion in 2026 at a compound annual growth rate (CAGR) of 22.5%. The growth in the historic period can be attributed to growth in electric vehicle adoption, deployment of smart building energy systems, expansion of distributed energy resources, early implementation of vehicle-to-building pilots, increasing focus on energy resilience.

The vehicle-to-building power market size is expected to see exponential growth in the next few years. It will grow to $3.81 billion in 2030 at a compound annual growth rate (CAGR) of 22.2%. The growth in the forecast period can be attributed to increasing investments in vehicle-grid integration, rising demand for decentralized energy systems, expansion of smart commercial buildings, growing adoption of renewable energy integration, increasing regulatory support for bidirectional charging. Major trends in the forecast period include increasing adoption of bidirectional charging infrastructure, rising integration of evs with building energy systems, growing use of ev batteries for peak load management, expansion of smart energy management platforms, enhanced focus on grid resilience.

The growing adoption of electric vehicles is anticipated to drive the expansion of the vehicle-to-building power market in the coming years. Electric vehicles (EVs) are automobiles or other modes of transport that operate fully or partly on electricity rather than conventional gasoline or diesel fuels. The penetration of electric vehicles is increasing due to improvements in battery technology, which enable extended driving ranges, quicker charging times, and reduced costs, making EVs more feasible and appealing to consumers. Vehicle-to-building power supports electric vehicles by enabling them not only to draw electricity from the grid for charging but also to supply power back to buildings during periods of peak demand, thereby improving energy efficiency, lowering costs, and fostering a more resilient and sustainable energy system. For example, in January 2025, according to Cox Automotive, a US-based system software company, electric vehicle sales in 2023 were revised upward to 1,212,758 units, reflecting a 49% increase compared to 2022, and continued to rise in 2024 by 7.3% to reach 1,301,411 units. As a result, the increasing penetration of electric vehicles is fueling the growth of the vehicle-to-building power market.

Key players in the vehicle-to-building power market are focusing on innovations such as integration with renewable energy systems to enhance energy efficiency and reduce peak demand costs. This integration involves connecting solar or wind power sources with V2B systems to increase the use of clean energy, reduce grid dependence, lower energy costs, and promote sustainable, low-carbon energy consumption. For instance, in May 2024, Fermata Energy LLC, a US-based EV charging provider, partnered with Xcel Energy Inc., a US-based electric services company, to launch a vehicle-to-building (V2B) pilot in Boulder, Colorado. The project transforms parked EVs into mobile power units that can supply energy back to buildings, helping offset peak demand, reduce electricity costs, and strengthen grid resilience, while supporting underserved communities and demonstrating the potential for V2B integration with renewable energy. The pilot uses Fermata Energy’s intelligent bidirectional charging platform, paired with FE-20 chargers and Colorado CarShare’s Nissan LEAFs, to showcase how EVs can serve as distributed energy resources.

In January 2024, Siemens AG, a Germany-based technology company, acquired Heliox B.V. for an undisclosed sum. This acquisition enables Siemens AG to strengthen and expand its eMobility business by enhancing fast-charging solutions for eBus and eTruck fleets, broadening its digital and software capabilities, and accelerating growth in the expanding EV charging infrastructure market. Heliox B.V., based in the Netherlands, specializes in providing vehicle-to-building power services.
