Eirgrid forecasts reduced risk of winter power outages

Ireland's electricity grid manager, Eirgrid, has predicted a lower risk of power outages during the upcoming winter months. From next month until the start of April, the organization anticipates adequate generation capacity and an improved outlook compared to previous years. According to Eirgrid, the risk of insufficient generation meeting demand has decreased to 0.8 hours this winter, a significant reduction from 1.1 hours last winter, 3.6 hours the year prior, and 21 hours the winter before that.

The improvement in power generation can be attributed to the addition of 275 megawatts of new gas-fired plants, 63 megawatts of new batteries, and an extra 809 megawatts of wind and solar generation. One gigawatt of power can meet the needs of 500,000 customers. Eirgrid's Director of System Operations, Diarmuid Gillespie, noted the impact of residential rooftop solar panels, which have also contributed to generation.

Moreover, Eirgrid has tapped into four gas and kerosene-powered generators at four different sites, capable of delivering up to 650 megawatts of power. The organization retains the option to request data centers to reduce power usage if there is a risk of demand exceeding supply, though this measure has not been implemented thus far.

In addition to domestic generation, Ireland also relies on four electricity interconnectors and one gas interconnector for additional supplies. While Ireland does not have gas storage, the State is planning to establish a floating gas storage terminal.

Environmental objections have delayed plans for a private liquid natural gas terminal in Tarbert, Co Kerry. Last winter, the peak demand for electricity was below Eirgrid's forecast due to mild weather. A one-degree Celsius decrease in temperature results in an additional 55 megawatts of increased demand, highlighting the significant influence of weather conditions on winter electricity demand.
