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 ...

The Administration has set the nation on a rapid transition to an “all-electric everything” energy economy powered predominantly by intermittent renewable energy. The goal is to complete this transition by 2050. There is ...

The Administration’s All-Electric Everything goal would require the addition of approximately 4,800 GW of storage supported rating plate capacity renewable generation with a capacity factor of approximately 30%, depending on the ...

Capacity factor:  The ratio of the electrical energy produced by a generating unit for the period of time considered to the electrical energy that could have been produced at continuous full power operation during the same period. (EIA...

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 US energy industry is subject to intense regulation and oversight at both the federal and state levels. Federal regulation is provided by the Federal Energy Regulatory Commission (FERC). National oversight of the electric energy ...

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 ...

The historical paradigm of the US electric industry has been “the energy you want when you want it.” Generation was adjusted to match contemporaneous demand as required.

The average demand on the US electric grid is ...

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 capacity of the US electric grid has historically been designed to meet peak demand, with limited additional generating capacity equal to +/- 20% of peak demand or sufficient to replace the capacity of the largest generating unit on the...

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 two defining characteristics of electric grid-scale storage systems are the amount of power they can deliver continuously (MW, GW, TW) and the total amount of power they can deliver before they are depleted (MWh, GWh, TWh). For example,...

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, ...
