The company, which runs the power grid on the national grid, has hit record-breaking peak demand since 2010, twice in the last seven days.
Ergrid said the first shutdown of two peat-burning power plants in the Midlands led to their forecasts for supply and demand in 2021.
But the company has warned of a possible power deficit in the coming months.
When the wind blows, renewable generation power output is low and Ireland’s national grid is weak if there is not enough support from the UK across interconnectors.
Earlier this week, Ergrid issued an amber alert during record peak demand for technical faults at three power stations.
ESB’s West Offali power station ceases production today after 52 years, followed by the Lough Re power station next Friday.
But Ergrid said the risk of generator forced failures at other stations is increasing.
Political representatives in the Middle East say both stations should be kept on standby, although ESB networks are not an option under planning and licensing rules.
“This is a sad day for the people of the Middle East,” said Pippa Hackett, Minister of State for Lands and Biodiversity.
Speaking on RTE’s Morning Ireland, the Green Party senator said the board na mana was incredibly good for the people and workers in the area, but “the future must be bright.
Denise Notton, a freelance TD for Galway-Rosecomon, said there should be an open and clear discussion on the two plants power plants at Shannbridge, Co Ophaly and Lansboro in Co Longford.
He urged Minister Hackett to redouble his efforts to help the agricultural sector and employment across the region.
“If we can convert these two plants into 100% locally produced biomass, it will reduce carbon emissions from farms in the area by 600,000 tonnes, which is equivalent to taking 130,000 cars off our roads. It provides 4,000 seasonal jobs and pays farmers about $ 465 per hectare.
MS Hackett said it was not practical to convert two more power stations to biomass.
When asked if Fianna F ടിil TD Barry Cowan’s proposal to transfer the plants from the ESB to the local authority and whether to hold an open tender competition for future use beneficial to the area, she said all suggestions would be considered.
Not only is burning peat inefficient, but two power stations in Shannonbridge and Lansboro need to be shut down because the form of pollution is a form of energy.
They also said that burning peat provides a small percentage of our total supply energy supply. She said these communities and workers can do better.
Notton alleged that the energy transition was an investment transition and that he wanted to bring us back to the 1930s.
