"It is those three parties that propose an option that, at the expense of all Lithuanian people facing an electricity price hike, would only slightly reduce heating prices in Vilnius, Kaunas, two other major cities and would create the conditions for their municipal companies to have even higher profits," she told reporters on Tuesday.
"Zuokas' Taip [movement], the Social Democrats, and the Labor Party voted in favor of that. I want to draw the attention of all our people. Be careful about voting for those who make promises to you but do everything contrary to what is in your interest," she said.
The president was commenting on a resolution passed by the City Council of Vilnius in which it calls for increasing electricity purchase quotas for combined heat and power plants and buy electric power at the same price as that fixed for the Lithuanian Power Plant in Elektrėnai.
Following the passing of the resolution last week, Vilnius Mayor Zuokas called on Grybauskaitė to press the government and the Energy Ministry to change the quotas fixed on supported electricity production for 2013.
Prime Minister Andrius Kubilius has also dismissed calls from heat producers and the capital city's top officials.
Kubilius said last month that competition for electricity production support would soon lose meaning, because the Elektrėnai plant would be producing cheaper power at its new unit.
Lithuania is holding general elections on 14 October.
