He said government was forced to decrease the tariff due to agitation by people.
"Because of people's struggle, the government has reduced the rates. We congratulate the people of Delhi. But it is a very marginal reduction, more of cosmetic. Struggle would continue," he said.
He said the previous rise in tariff will continue if one consumes more than 400 units of electricity. "So people will continue their struggle," he said.
Earlier in the day, Kejriwal also expressed solidarity with BSES employees here who staged a protest outside their office in Karkardooma.
