How solar homes become power stations on the UK smart grid: THE CONCEPT: Instead of one-way power (grid → home), solar + battery enables two-way flow. Your home generates, stores, and exports electricity on demand. SCALE: If all 1.3M UK solar homes participated in flexibility services with 3kW average export capacity: total = 3.9GW of distributed flexible capacity. This equals FOUR gas power stations. FLEXIBILITY SERVICES: National Grid ESO and DNOs pay for 'demand response' — turning down consumption or exporting stored energy during grid stress. Current payments: £50-£150/yr per household for participation. Octopus Energy 'Powerups' already pays solar + battery homes to export at premium rates during grid stress events. WHAT YOU NEED: Solar panels + battery + smart meter + participating energy supplier (Octopus, OVO, British Gas). TIMELINE: Basic demand response: available now. Sophisticated local energy markets: 2028-2030. Full peer-to-peer energy trading: 2030+. Sources: National Grid ESO (nationalgrideso.com), Ofgem Future of Local Energy, UK Power Networks.
