The ESB says it could cost up to 5 million euro to save the Poolbeg chimneys.
Its Chief Executive told the Business Post investigations into the condition of the towers will start this summer.
The chimneys were built in the 1970s and were decommissioned in 2006 and 2010.
Labour Party Councillor for Dublin, Dermot Lacey say if some thought goes into how the stacks would be used, it's not the worst way to spend money.
