An environmental charity says it is still not convinced enough will be done to protect wildlife if the Sizewell C nuclear plant goes ahead.
Energy giant EDF today launched the third and final public consultation into its plans for a third power station on the Suffolk coast.
It claims it will create 25,000 jobs and bring millions of pounds into the local economy.
But, despite two previous public consultations and a number of changes, EDF has yet to over its critics.
Among them is the RSPB which runs the Minsmere reserve just a stone's throw from the proposed Sizewell C site.
Area manager Adam Rowlands said he was still not convinced enough thought had been given to the protection of wildlife.

Sizewell is already home to two power stations - one which has been decommissioned and one still in use.
People living in nearby villages say a third plant would push local infrastructure over the edge.
Up to 1,500 lorries a day are expected to head to and from the construction site if it goes ahead, with nearly 2,500 workers to be housed locally.
EDF's latest consultation has made changes to how it plans to get workers and materials in and out of SIzewell, including a bypass for Theberton village and a possible link-road to connect the site to the A12.
But campaigners - who have been opposing the proposals for many years - remain unconvinced.
EDF Energy told ITV News Anglia it believed it had listened to the feedback it had received previously and would take into account views given during this latest consultation.
Jim Crawford, project development director for Sizewell C, admitted there would be some impact on Minsmere but said EDF intended to help mitigate that.
The stage three consultation runs for 12 weeks until March 29.
Sizewell C timeline:
Talk of a third power station at Sizewell began more than 30 years ago
EDF launched its first public consultation back in November 2012
This third consultation will run for 12 weeks, until March 29th
A planning application could be submitted next year but EDF will then have to wait for approval from the planning inspectorate followed by the government
EDF hopes it can begin construction in 2022
That is likely to take around 10 years to complete
