Prior state
Chinese module and cell overcapacity has driven equipment prices to levels where a household or firm facing high retail tariffs and unreliable supply recovers its outlay in a few years. Utilities in several large markets carry legacy capacity payments, fuel-import exposure and circular debt, and cover their costs by cross-subsidising small consumers from large ones.
Material change
The direction of electrification reverses: instead of demand migrating onto the grid, load migrates off it. As storage makes evening supply viable, the largest and most creditworthy customers defect first, collapsing the cross-subsidy base. Governments are forced to rewrite tariff structures, restructure or unbundle utilities, renegotiate independent-power contracts, and treat the grid as a balancing and backup service rather than the default source of energy.
Why now
Modules and cells crossed their price thresholds in the 2020s, but storage — the piece that makes defection complete rather than partial — reaches mass affordability at the turn of the decade. Utility revenue erosion is cumulative: it becomes a solvency event only after several years of compounding defection, which places the fiscal reckoning here rather than earlier.
Mechanism and resistance
Utilities, fuel importers, transmission unions and finance ministries resist, because stranded capacity payments and sovereign guarantees do not disappear when customers do. Regulators experiment with fixed charges, net-billing reform and minimum-demand contracts, which slow but do not stop defection. Distributional politics cut the other way: defection by the affluent raises tariffs for those who cannot afford equipment, and grid quality degrades for the people most dependent on it.
Consequences
Effective electricity access rises considerably faster than grid-connection statistics indicate, and the character of access changes — small, reliable, expensive per kilowatt-hour, and privately owned. Diesel generation and fuel imports fall, easing balance-of-payments pressure. Utility restructuring becomes a recurring condition of lending programmes. New vulnerabilities appear: replacement cycles for batteries, unregulated installation quality, financing for households without collateral, and a growing electronics waste stream with no disposal system.
End state
In several South Asian and African economies, customer-sited generation accounts for the majority of new capacity additions and a large minority of consumption; national utilities have been restructured, recapitalised or partially dismantled; and the grid's role has been redefined.
Observable test
Share of annual capacity additions that is customer-sited in Pakistan, Nigeria, South Africa, Kenya and Bangladesh; utility sales volumes and tariff-structure changes; national module and cell import statistics.
Disconfirming sign
Utility-scale procurement lowers retail tariffs enough that behind-the-meter additions stall and grid sales resume growth.
