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 ...

In a summary of a recent peer-reviewed paper, the principal author stated that an electric grid predominantly powered by intermittent renewables such as wind and solar would require storage approximately equal to 25% of annual generation to...

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 UN and numerous national governments are promoting the fantasy that the global energy economy can transition to a fossil-fuel-free, all-electric everything energy economy by 2050. In this fantasy, intermittent renewable generation ...

Government, at all levels, apparently believes that its responsibility in the proposed energy transition is to establish the goals, set the timeline, pick the winning technologies and incentivize their market adoption. This perception led ...

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 federal government has set a goal of transitioning the US energy economy to a fossil-fuel-free, “all-electric everything” energy economy by 2050. This transition would require an approximate tripling of the US electricity...

The renewable energy industry apparently believes that its responsibility in the proposed energy transition is take maximum advantage of federal and state subsidies, incentives, preferences and mandates by installing as much generating ...

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 ...

One of the most contentious issues in utility ratemaking has been the issue of allocation of both capital and operating costs among customer classes. This allocation has been accomplished through monthly service charges, time of day rates, ...
