THE ESB has been granted planning permission for a €150m redevelopment of its headquarters in Dublin.
The State-owned electricity provider confirmed to the Irish Independent that plans for a complete redevelopment of its Fitzwilliam Street site had been granted by Dublin City Council.
A spokesman said the ESB was pleased with the decision.
"ESB welcomes the decision by Dublin City Council Planning Authority to grant permission for the redevelopment of our Fitzwilliam Street site.
"The development has the potential to deliver one of the most efficient, sustainable and commercial office complexes in the city, while sensitively respecting and enhancing the Georgian streetscape," he said.
Under conditions set by the council's planning authority, the ESB will have to provide a "detailed methodology" on how it will protect the architecture of adjoining buildings before it begins development.
It will also have to pay €941,840 towards the proposed Metro North Scheme and contribute €654,706 for the development of public infrastructure and facilities in the area.
The ESB spokesman said it would "over the coming days, examine all of the details of the decision in full".
In 2013, the company announced details of the redevelopment, with plans to more than double its occupancy.
The 1.2-hectare site at 27 Lower Fitzwilliam Street will be overhauled into a seven-storey building within the current 30,000 square metre floor space, according to the proposal.
The ESB plans to reduce operating costs by half, while improving its Building Energy Rating (BER) from 'F' to 'A'.
The winning design for the replacement offices was developed by Irish architects Grafton Architects and O'Mahony Pike Architects.
A previous development in the 1960s involved the controversial demolition of 16 Georgian buildings, on what was known as the 'Georgian Mile'.
