Singh said he had also sent Kiren Rijiju, his deputy in the ministry, to the state for a survey of the affected areas.
"We will provide all necessary assistance to the state," Singh told the MPs from Kerala during the Zero Hour.
CPI(M) leader P Karunakaran said six districts in the state have been badly affected.
At least 20 people have died in the Idukki district due to heavy rains and floods, while five people lost their lives in Wayanad, he said demanding military assistance.
"For the first time, shutters of 22 dams were opened to release excess water while water from the Idukki reservoir was also released after 26 years, flooding the Periyar River," Venugopal said and demanded a special financial package for the state.
Kerala has been pounded due to heavy downpour, resulting in the swelling of rivers and flooding in several parts.
