EirGrid was not in a position to provide the monthly breakdown for 2006 but has advised that the annual consumption of electricity in 2006 was 27,920.4 gW hours (based on 52 weeks) where 1 gW hour is 1,000 Mega Watt hours. EirGrid now publishes monthly electricity statistic reports on its website and this data, which includes details on monthly electricity demand, demand growth, peak demand and installed generation capacity, is readily accessible in respect of the months from July 2009 onwards.
EirGrid also publishes an annual Generation Adequacy Report, which sets out estimates of the demand for electricity in the following 7-year period, the likely production capacity that will be in place to meet this demand, and assesses the consequences in terms of the overall supply/demand balance. In its most recent Generation Adequacy Report for the period 2010 to 2016, EirGrid highlighted that the change in the economic climate since 2008 has been reflected in a reduction in electricity demand. It also noted that this reduction in demand, coupled with the connection of new generation, improved generator availability, and increased interconnection, means that there is adequate capacity to meet demand in accordance with system standards over the next seven years.
