Upto 200 units of electricity will be free in Delhi from today, Arvind Kejriwal announced today. Power consumed between 201 and 400 units will be at half price as the Delhi government will provide 50 per cent subsidy, he added. "Today the cheapest electricity in the country is in Delhi," the Chief Minister said, calling it a "historic decision" that would help the "aam aadmi (common man)". Under the "Free Lifeline Electricity" scheme, those consuming 200 units of electricity each month will get no bill.
