A company has been charged with health and safety offences following the death of a worker at a Flintshire power station in 2007.
Michael Benn, 37, from Fife, Scotland, died after falling into a cooling water chamber at Connah's Quay power station.
Representatives from EPSCO Ltd, of Aberdeen, appeared at Flintshire magistrates court charged with various offences.
The case was committed to Mold Crown Court for a hearing in September.
Mr Benn was a contractor working at the plant, which is owned by E-on.
He was pulled from the tank using specialist water rescue equipment and was treated at the scene, but died shortly before arriving at Wrexham Maelor Hospital.
EPSCO Ltd is charged with failing to ensure the health and safety of Mr Benn and other workers, and failing to assess the risks involved in the cleansing and disinfecting of the cooling tower.
