Storage Adoption Map
Sector maturity, mapped honestly
Stationary storage is scaling at wildly different speeds across homes, shared residential buildings, commercial sites, utility-scale projects, and EV charging hubs. This is a map of where each sector stands today — not a country ranking. Where the public data is still too thin to rank fairly, we say so rather than fake a number.

Sector adoption map
Compare where stationary storage is gaining traction first, and where data coverage is still too thin for confident country rankings.
Home solar + battery
Early adopterPrimary metric to track
Solar-plus-storage attachment rate
Residential batteries become attractive where backup power, time-of-use tariffs, low export value, or zero-bill planning matter.
Data gap
Needs country-level utility interconnection records or installer survey data, split from standalone solar installs.
Shared residential
Pilot / designPrimary metric to track
Buildings with shared BESS or apartment-level storage
Useful for condos and apartments where one battery can serve common loads, solar self-consumption, or backup needs.
Data gap
Needs building-level project registers and clear separation between common-area solar and tenant energy use.
Commercial + industrial
Emerging procurementPrimary metric to track
C&I sites using storage for demand, backup, or arbitrage
Adoption is driven by peak demand charges, diesel replacement, backup requirements, and solar self-consumption economics.
Data gap
Needs project-level deployment data by sector: factories, offices, retail, data centres, warehouses, and campuses.
Grid / utility scale
Fastest scalingPrimary metric to track
MW / MWh connected to transmission and distribution grids
Globally, utility-scale projects supply most new battery power capacity and are the clearest source-backed adoption signal today.
Data gap
Needs country-specific project pipelines, commissioning dates, duration, owner, offtake structure, and co-located solar or wind status.
EV charging + depots
EmergingPrimary metric to track
Charging hubs buffered by stationary storage
Batteries can reduce grid connection size, smooth fast-charging peaks, and pair charging depots with cheaper solar energy.
Data gap
Needs charging-site disclosures: storage size, charger load, utilisation, tariff structure, and solar co-location.
Rules for this scoreboard
EV battery packs are tracked separately from stationary BESS.
BESS is storage capacity in GW and GWh, not an electricity generation source.
Country rankings need sector-level interconnection or project data before they are useful.
