This commentary suggests a reporting format for the renewable plus storage demonstration discussed in the prior two commentaries.

• Renewable Demonstration
• Transparency

Developers of renewable energy generation installations frequently focus their marketing efforts on estimates of the number of homes the installations would serve. The developers’ estimates are not based on consistent assumptions and ...

The electric utility grid requires instantaneous balancing of demand and supply. Historically, most fluctuations on the grid were the result of changes in customer demand. However, as intermittent renewable sources of generation are added ...

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 ...

One of the idyllic images cherished by many environmentalists concerned about the climate is life “off the grid”, free of utilities, living off the land, minimizing their impact on the planet. However, reality frequently rears...

The Precautionary Principle is frequently cited as the justification for actions to halt or retard climate change. This commentary will question the application of the principle to the design of a renewable plus storage electric grid.

The ...

I believe it is essential that at least one large scale demonstration of a completely freestanding renewable plus storage powered grid be conducted under carefully controlled conditions. This demonstration should begin as soon as possible ...

The wind and solar generation systems installed in the US have been installed in the most favorable locations available, for obvious reasons. However, as wind and solar generation are expanded toward a renewable plus storage generation ...

Intermittent renewable generation displaces a portion of the output of conventional coal and natural gas generators, but does not replace those generators. However, depending on intermittent renewable market penetration, the annual output ...

I believe that the demonstration project described in the previous commentary should be conducted rigorously and transparently, with broad website access to hourly, daily, monthly and annual data.

The first step in this process would be ...
