To reduce the strain on the national grid during peak hours, regulators are considering cutting off power to household geysers. But there are far better options than this heavy-handed approach to demand management, which would bring a range of unintended consequences.
Among the technologies being piloted are systems that allow authorities to control your home’s electricity usage. Those include ripple relay systems — which are used to halt the supply of power to geysers — and load-limiting smart meters, which suppress electricity supply to households...
