The corresponding [[engineering branch]] is called '''Power System Operations and Control'''. Electricity is hard to store, so at any moment the supply (generation) shall be balanced with demand. In an electrical grid the task of real-time balancing is performed by a regional-based control center. ~~(in~~In the [[North American power transmission grid]], these centers belong to ''[[balancing authority\|balancing authorities]]'', numbered 74 in 2016.<ref>{{cite web \|title=U.S. electric system is made up of interconnections and balancing authorities \|url=https://www.eia.gov/todayinenergy/detail.php?id=27152 \|website=eia.gov \|publisher=[[United States Energy Information Administration]] \|access-date=31 May 2022 \|date=20 July 2016}}</ref>) The other form of sharing resources of multiple power plants is [[power pool]].{{sfn\|Bhattacharya\|Bollen\|Daalder\|2012\|pp=54}} == Day-ahead operation ==
