Market Overview and 2026 Implications

The global smart grid market is expected to reach USD 161.15 billion by 2029. This will be driven by grid automation, advanced metering, communications, and grid software platforms.

Further, global electricity demand is expected to grow by an average of 3.4% annually through 2026. This demand acceleration strengthens the business case for smart grid rollouts because the system needs more flexible distribution operations, tighter congestion management, and faster interconnection.

McKinsey’s analysis of the data center buildout projects global data-center power demand reaching 1400 TWh by 2030, or roughly 4% of total global electricity demand. For smart grids, high-density, fast-ramping loads force utilities to invest in visibility, automation, and demand-side flexibility at the feeder and substation level.

Moreover, annual investment in electricity grids has been running at about USD 300 billion per year and needs to rise to over USD 600 billion per year by 2030 to stay aligned with net-zero pathways. The same analysis estimates the world will need to add or replace ~80 million km of power lines by 2040.

Explore the Data-driven Smart Grid Market Report for 2026

The US EIA reports that advanced metering infrastructure (AMI) smart meters in the US reached ~119 million in 2022. This represents ~72% of all installed electricity meters. The EIA also reports that ~73% of residential meters were AMI-enabled.

This is a practical indicator that the data layer needed for demand response, outage management, and distributed energy resource (DER) orchestration is now mainstream across large parts of the US utility footprint.

FERC’s annual demand response and advanced metering assessment shows that US advanced meter penetration reached 72.3% in 2022. Advanced meters increased from 111.2 million (2021) to 119.3 million (2022). This year-over-year increase matters in a smart grid context because it reflects continuing utility capex allocation to the grid edge.

Further, global smart meter installations exceeded 1.8 billion units by the end of 2024, and the installed base is expected to surpass 3 billion by 2030. Adoption is uneven, with North America at ~77% penetration in smart electricity metering by end-2024.

The European Commission estimates Europe needs EUR 584 billion of investment in electricity grids by 2030 and notes that ~40% of distribution grids are over 40 years old. Its grid package materials also highlight the pipeline scale: 85 grid/infrastructure projects with the potential to add 93 GW of cross-border transmission capacity.

 

 

The global smart grid market size is predicted to reach around USD 52.58 billion by 2026, and approximately USD 238.63 billion by 2035 at a CAGR of 17% from 2026 to 2035.
