Construction work on the controversial €500m Poolbeg incinerator project will begin before the end of the year.
A report due to be circulated to Dublin city councillors will reveal that the city will make up to €155m if the waste energy plant is built.
However, the city would have to write off costs of €105m if the 550,000-tonne capacity waste-to-power project is scrapped.
And the report has said that the land bought for the project was now worth just €6m - €46m less that when it was bought.
Councillors have been given formal notice that the project is to proceed. However, a final decision will not be made until after local politicians have been consulted.
The National Development Finance Agency (NDFA) has said that the project represents good value for money. The European Commission has also rejected complaints that competition law and procurement rules were broken when the council made agreements with a private sector partner to build the facility.
The decision to proceed is an executive function of management at the four Dublin local authorities.
While councillors voted in March to abandon the project, elected politicians have no say.
It is expected that the decision to proceed will be made "within weeks", and that construction works could begin before the year is out.
