Electric grids have demonstrated the ability to adapt to some fraction of intermittent renewable generation, as long as there is sufficient dispatchable generation available to meet contemporaneous grid demand when the intermittent ...

Electricity demand fluctuates continuously, over a range of 2.5-3 to one. Electric utility operators control the output of numerous generation resources over their acceptable range of operation to match the contemporaneous demand of the ...

The past two years have provided unpleasant lessons for several electric utilities and their customers. The challenge remains for those utilities and the utility industry to learn from those lessons and take actions to prevent their ...

Numerous potential paths to net zero annual CO2 emissions have been identified and discussed, including:

• Renewables plus storage
• Massively overbuilt renewables and transmission
• Renewables plus Dispatchable Emission-Free Resources (DEFR...

The US electric utility industry has historically sought to achieve “four nines” (99.99%) reliability of service. One key to achieving very high system reliability has been maintaining an approximate 20% capacity reserve margin ...

The US currently has approximately 1,250GW of electric generating capacity. Approximately 200GW of that capacity is coal generating capacity, of which approximately 50GW is scheduled to be retired through 2029. The remaining approximately ...
