India's annual infrastructure output grew 4.7 percent in April from a year ago, government data showed on Thursday.
The growth in output compares with a upwardly revised 4.4 percent year-on-year growth in March.
Infrastructure growth slowed to a three-year low of 4.2 percent in 2017/18 fiscal year, indicating Prime Minister Narendra Modi faces a tough challenge to boost investment ahead of general elections due early next year.
Infrastructure output, which comprises eight sectors such as coal, crude oil and electricity, accounts for nearly 40 percent of India's industrial output.
