The city council is to consider taking the tram network into Newhaven, Ocean Terminal or the foot of Leith Walk.
The line currently stops at York Place, but councillors will consider options to extend the route from the city centre along part of the originally planned route – a plan scaled down when the project ran into financial difficulties -at a meeting next week.
Extension cost estimates are £144.7m to Newhaven, £126.6m to Ocean Terminal and £78.7m to Leith Walk.
Transport Convener, Cllr Lesley Hinds, said: “I am extremely pleased with the progress of the business case, which already shows the clear economic impact the extension of the tram line could have on the city.
“In the tram’s first year of operation we have seen passenger numbers increase, demonstrating a growing demand for public transport in Edinburgh and making the case for extending the tram to benefit people elsewhere in the city.
“But we don’t want to make any rash decisions about the future of the project, and that’s why further due diligence is required to ensure a robust financial case that can be used as a basis for an informed judgement. We will also be exploring all avenues for funding, and considering a series of new and innovative options with a view to delivering best value.
“It is essential that we learn from our past mistakes and I am confident that this process will deliver thoroughly researched, strategic options for a tram extension.”
Further work is now to be carried out, including a formal market consultation, testing and auditing of the financial model and an investigation of alternative funding options, ahead of the final decision in autumn.

Edinburgh’s tram service began running in May last year, six years late and costing more than double (£776 milion) the original £375m price tag – and that price was for a trams network not just a single line.
A public inquiry was set up last year under Lord Hardie to establish why the Edinburgh Trams project ‘incurred delays, cost more than orignally budgeted and through reductions in scope deliverd significantly less than projected’.
A formal call for members of the public to provide written evidence was issued on 12 May this year and a list of issues has been published. An online survey has also been created to give people an easy way to submit this evidence.
