Summary of Article: Installing rooftop solar (RTS) on “every building” would transform electricity systems by decentralizing generation, reducing losses, and accelerating decarbonization—but it would also stress low‑voltage networks without parallel investments in smart inverters, storage, and tariffs that value time and location. A landmark global study estimates ~27 PWh/yr of rooftop potential—more than 2018 global electricity use—with India among the lowest‑cost markets for rooftop generation (≈**$66/MWh**). In India, recent policy— PM Surya Ghar: Muft Bijli Yojana —has catalyzed residential RTS growth and targets 1 crore households by FY‑2027, offering up to 300 units/month free via subsidized systems and concessional loans. [nature.com] , [zenodo.org] [pmindia.gov.in] , [mnre.gov.in] Economically, PV module and storage cost curves remain favorable: utility PV LCOE hovers around $39/MWh globally (2025) and is expected to fall ~30% by 2035 ; battery LCOE for four‑hour systems ...

Executive summary If P2P energy trading scaled from pilots to the default way small customers buy and sell electricity, distribution systems would shift from passive, one‑way delivery to actively managed local markets. The upside: lower system costs through avoided network upgrades, higher renewable absorption, new retail propositions, and greater customer engagement. The risks: operational complexity at the grid edge, fragmented liquidity, and consumer protection/data‑privacy concerns. A credible path to mainstreaming requires:  Clear legal rights for energy sharing/trading,  DSO‑centred market governance and digital infrastructure (asset registries, data standards, settlement),  Tariffs that internalize network constraints, and  Interoperability across platforms. Evidence from the IEA’s GO‑P2P initiative, EU’s Clean Energy Package, UK flexibility reforms, Australia/Singapore trials, and India’s 2026 Delhi sandbox shows the building blocks exist; what’s missing is c...

The global electricity landscape is undergoing a structural shift from centralized generation toward decentralized, consumer-led production. Advances in rooftop solar photovoltaics (PV), battery storage, smart meters, and digital grid technologies have enabled households and businesses to evolve from passive consumers into “prosumers.” But what if consumers generated 80% of their own electricity ? Such a scenario would fundamentally reshape power markets, grid economics, infrastructure investment, energy equity, and decarbonization pathways. This article evaluates the systemic implications—strategic, financial, technological, and regulatory—through a consulting lens. 1. The Rise of the Prosumer Economy Distributed generation—electricity produced at or near the point of consumption—has grown rapidly, particularly via rooftop solar. Households, commercial establishments, and farms are increasingly installing solar PV systems to offset grid purchases. Globally, distributed solar alre...
