SSE Airtricity are cutting 11 jobs at Tarbert Powert Station.
The company is carrying out what is a voluntary redundancy programme in December and have informed staff representatives at the plant today.
SSE airtricity receives funding from Eirgrid and was paid €139m by the state energy company from 2011 to 2015 to a power the plant
The company says the redundancies are needed to remain competitive preparation for the introduction of the new Integrated Single Electricity Market in late 2017 and to safeguard the continued operation of Tarbert Power Plant.
Tarbert is one of the oldest power plants of its kind in Ireland and is primarily in place to maintain security of electricity supply by being available to operate on quick responses to peaks in national energy demand.
Because of its age it takes much longer to power up than newer plants.
SSE acquired planning permission for a Combined Cycle Heat and Power Plant at Tarbert when it purchased it from previous owners Endesa but have not as of yet moved to devlelop it. It has developed a new 464MW plant at Great Island, Co. Wexford, which entered commercial operation last year.
Fianna Fáil Deputy John Brassil has expressed concern at the companies announcement today and called on the government to intervene.
