29 February: An Academic Calendar Update

February 29 and Electricity System Planning

February 29 can affect the energy sector by introducing an additional day into electricity system calculations and operational planning. In a leap year, energy demand and electricity production continue for one extra day, which must be reflected in supply projections and energy accounting.

For variable renewable generation, such as solar and wind, the additional day also provides another opportunity to generate electricity and collect operational data.

Overall, the effect of a leap year may involve additional calculations, planning, and data collection, but it is generally modest and accommodated through routine power system management.
