PM Modi has made full electrification a key goal as he seeks to shore up support among rural voters.
The Centre said it's on track to meet its official March 31 deadline to provide electricity connections to every home, saying a December 31 goal promoted publicly by the power ministry was only an "internal target."
The power ministry said in a statement on Wednesday that it aimed to achieve full electrification by year-end "so that even if some states fall behind the internal target date they will still be able to complete the household electrification well before the official target date."
Both schedules have been cited by the PM Modi-led government on different occasions. Power Minister RK Singh said in November that the government would achieve full electrification by the end of 2018, a deadline it missed.
In April, the ministry said the government launched the initiative -- "Pradhan Mantri Sahaj Bijli Har Ghar Yojana," which translates to Prime Minister's Power Plan for Every Home -- "to achieve universal household electrification in the country by December 31, 2018."
Simultaneously through last year, Mr Singh maintained the official deadline of March 2019 in written responses to questions in the nation's parliament.
PM Modi, whose Bharatiya Janata Party faces tough national elections in the coming months, has made full electrification a key goal as he seeks to shore up support among rural voters.
