NEW DELHI: Delhi surrendered its allotment of 2,083 mw, or more than half its current daily demand, from November 1 even as the city suffered widespread blackouts between second week of that month and continued till the first week this month.

While CM Sheila Dixit talked tough and ordered discoms to tie up supplies in advance to avoid similar outages in summer, senior state government officials blamed lower generation at state-run NTPC's power plant at Dadri as a result of fog disrupting rail service and delaying coal supply.
