The amount of electricity generated by Ireland’s wind farms broke the 1,000 megawatts (MW) barrier for the first time last weekend, providing enough power to supply the needs of 650,000 homes.

The very windy conditions last weekend resulted in an all-time peak wind output of 1064 MW on Saturday, generating enough power to supply the needs of 650,000 homes, according to EirGrid.

Wind output remained high throughout the day, with renewable energy at some times supplying 33 per cent of demand from electricity customers.

“This recent high level of wind generation shows the significant potential we have in Ireland to utilise this clean, green, indigenous fuel,” said Dermot Byrne, chief executive of EirGrid, the agency that operates the State’s electricity transmission system.

“Ireland has ambitious renewable energy targets and the breaking of the 1,000 MW barrier for the first time is a significant step on the road to meeting them,” he added.

Ireland is reputed to have the best general wind resource in Europe and wind farms here have a higher average output than those on the continent. Currently, there are over 90 wind farms in operation which have the capacity to supply up to a maximum of 1,161 MW at optimum conditions.

In addition, Ireland has 238 MW of capacity from hydro stations in counties Cork, Dublin, Donegal and Clare and a further 58 MW of power capacity from landfill gas.

The Government wants 15 per cent of all electricity used in the Republic to be generated from renewable sources by next year.

MORE than 400,000 homeowners will be forced to buy a licence for their septic tank under new laws planned for next year.

Yesterday, Environment Minister John Gormley said he would introduce a licensing and inspection system for septic tanks, which will affect 440,000 homes across the country, mostly in rural areas.

The department has not yet decided how much a licence will cost, but in Scotland similar licences cost €82.

And some homeowners could be forced to replace their tanks if the licensing authority decides they are not working properly and pose a risk to public health.

Sources said that tanks located on waterlogged sites or with clay soil may have to be replaced at a cost of up to €4,000 per tank.

The move, which is a commitment in the Renewed Programme for Government, comes after the European Court of Justice ruled yesterday that Ireland had broken EU law for failing to enact legislation to deal with domestic wastewater from septic tanks and other treatment systems.

Pollution

Homeowners currently have a “duty of care” but, under a new licensing system, a public body — such as a local authority — will inspect tanks to ensure they are not causing pollution.

Fines of up to €5,000 or three months’ imprisonment can currently be imposed for not ensuring the wastewater is properly treated. Penalties are likely to be of a similar order under the new system.

Households not served by public sewers usually depend on septic tank systems to treat and dispose of wastewater.

A typical tank takes wastewater from a toilet, bath, kitchen and washing machine.

Heavy solids settle to the bottom where bacteria partially decompose them into sludge, and tanks are pumped to prevent overflowing.

Excess wastewater is filtered through the soil where it is absorbed. If tanks overflow or are not maintained, they can cause contamination of groundwater, rivers and streams with potentially dangerous bugs, including e-coli.

Yesterday, Mr Gormley said he would be considering the court’s judgment and introducing a licensing system.

“We know that in far too many instances septic tanks or on-site sewage treatment systems are causing pollution. The absence of a licensing and inspection system is a major weakness in our overall environmental management structures,” he said.
