"We will not rest till the company takes measures to lower the tariff," Nirupam said addressing the protesters who raised slogans branding Reliance Energy Chairman Anil Ambani as a "thief".
Dutt said there should be uniform power tariff in Mumbai and suburbs. "If the tariff is not lowered, the agitation will spread and more of our colleagues will join the stir," she said.
The MPs have been demanding a tariff cut with Nirupam even threatening to go on an indefinite fast.
Nirupam had written to Maharashtra Chief Minister Prithviraj Chavan demanding a cut in power tariff, asking if the AAP government in Delhi can do so why the same can't be done in Mumbai and Maharashtra.
Nirupam had also written to Anil Ambani asking him to be present during the agitation to address the public and explain his company's position.
Among the demands are for certain charges like the fixed charge and regulatory asset charge to be withdrawn by the company.
