Building-to-Grid: Grid-Interactive Buildings Engaged in Demand Response, Solar Power Generation, and Battery Energy Storage - Global Market Analysis and Forecasts, 2025-2034

As global electric grids are put under stress to meet growing energy demands and manage the introduction of more renewable distributed energy resources (DER), utilities will face more pressure to stabilize the grid. Building-to-grid (B2G) technologies-which enable buildings to interact with the electric grid and act as a grid resource-are effective solutions that, if managed properly, can help with grid stabilization. These technologies can directly benefit utilities, building owners, and residential homeowners as well as governments and energy consumers.

Market conditions are promising for increased B2G integration. As countries around the world work to stabilize and decarbonize their power grids, B2G integration will be a key component in achieving these goals. Additionally, increased interest in grid participation from building owners and residential homeowners have made B2G-enabling technologies more desirable, as evidenced by their increased adoption globally. Most of the barriers to B2G integration concern the market's maturity. As B2G integration is in its infancy, many questions remain about which technologies, business models, and policies will take hold as the market matures.

This Guidehouse Research report analyzes major trends in grid-interactive buildings engaged with three primary B2G technologies: demand response, solar power generation, and battery energy storage. The report provides an overview of these B2G technologies and the factors driving their adoption or limiting their growth. It forecasts the number of grid-interactive buildings, segmented by technology, building type (commercial, institutional, and residential), and region, from 2025 through 2034. The report concludes with specific recommendations for B2G stakeholders to promote B2G technologies in support of grid stabilization.
