‘Fish disco’ row risks fresh delays to Hinkley Point nuclear plant

EDF has been urged by campaigners to stick with plans to install underwater
loudspeakers to deter fish in the Bristol Channel, as the energy company
grapples with delays to construction of its Hinkley Point C nuclear
reactor.

The row over the “fish disco” deterrent, as it is known in
Whitehall circles, marks the latest salvo in the UK’s long-running battle
to balance growth with environmental protections. Mark Lloyd, chief
executive of The Rivers Trust charity, said France’s state-owned energy
company should keep its commitment to the acoustic fish deterrent, as part
of its Hinkley Point C project.

His comments follow warnings that wrangling
over fish protection risks further delaying completion of the Somerset
power plant, which is already several years behind schedule and billions of
pounds over budget. Plans for the deterrent system involve 288 underwater
speakers that would produce underwater noise louder than a jumbo jet all
day, every day for six decades, according to EDF.

Despite previously
agreeing to build an “acoustic fish deterrent”, EDF is now trying to
scrap those plans, saying they would endanger divers, and is instead
proposing salt marshes to shelter fish. But Lloyd argued that, unless the
acoustic deterrent was installed, “there are likely to be local
extinctions and a very significant impact on marine species throughout the
South West and the Irish Sea”. EDF rejects this characterisation,
pointing out that regulators estimate the amount of fish that will be
harmed without the deterrent is 44 tonnes per year, equivalent to an annual
catch of one small fishing vessel.
