  "account": "Home battery systems could slash household electricity bills, especially for renters, flat dwellers and low-income households who currently face barriers to installing traditional units. The government has taken steps to make plug-in solar panels available, and now, Regen argues, plug-in batteries should be made accessible too. Unlike traditional systems that require professional installation, plug-in batteries can be bought at retail outlets and plugged into a standard wall socket, eliminating the need for costly wiring. This affordability allows them to be used by a much broader range of households, potentially benefiting around half of all homes in Great Britain. By charging during off-peak periods and discharging during peak times, plug-in batteries can significantly reduce energy costs. In a 10-year analysis, a 3 kWh battery paired with a time-of-use tariff could pay for itself in about 2.5 years, with potential savings of up to £2,400 over the decade. The same battery could enable households to save 30-34% on their energy costs by utilizing off-peak periods and shifting demand. While plug-in batteries may not offer the same range of system services as larger systems, they can still contribute to grid flexibility and help integrate more renewable energy. Even with a modest discharge capacity, widespread adoption could still make a meaningful difference in overall energy efficiency and cost savings.",
