Time flies even during pandemics. Two years ago, I found the quote, “Casual observers are often wrong” by Charles Bayless with Public Utilities Fortnightly. Back then, the Rant topic was that battery storage increases carbon emissions – because “Batteries, or any storage, only swap dispatchable, conventional resources; never renewable resources. Result: increased emissions.” Whenever energyRead more

You all know people who are always going to do something great but never make it happen. Consider the hapless New Year’s resolution for which someone plans to lose weight. They successfully diet between a cheeseburger and fries for lunch and a mound of pasta with rich sauce for dinner: the “diet” lasted a fewRead more

The batteries are coming! Maybe. I recently participated in an EPA-sponsored webinar to explore the results of a couple of case studies of lithium-ion batteries used to shave and shape building electrical loads. The technology is more nascent or even embryonic than I would have guessed. Interestingly, I’ve read a lot about systems approaches toRead more

I’m not in the electricity storage business, but I can recognize lousy ideas when I see them. Grid-scale battery storage is a bad idea. It will never be anything more than a frequency and voltage regulation technology, although I have to say these are critical functions that batteries can provide. Innovation comes out of leftRead more

“Casual observers are often wrong.”  Why didn’t I think of this for a tagline?  It is a line inked by utility veteran Charles Bayless in the March issue of Public Utilities Fortnightly.  His article, “Does Storage Increase Carbon?” is the basis of this post.  By the way, many politicians make policy and law without knowingRead more

A recent webinar delivered some interesting facts to me. The average human brain weighs three pounds, as verified here. The presenter said the brain represents 2% of an average person’s weight but consumes 20% of the blood flow and calories. I thought, wow – that is interesting. The inverse of 2% is 50.  The averageRead more

I spent last week at the Grid Evolution Summit[1] presented by the Smart Electric Power Alliance (SEPA) in the Nation’s Capital. The opening speaker, Jeremy Rifkin, has authored 20-some books, the most recent of which is called, “The Zero Marginal Cost Society.” This post is based on a related article you can read yourself, here.Read more

A couple years ago at an AESP conference, we had a fascinating speaker and topic. It was one of those that had me thinking deeply and philosophically. The subject was technology and the future. The takeaway: every problem is either a technical problem or one of human flaw. As for technical problems, there is nothingRead more

The Association of Energy Services Professionals (AESP) Summer Conference included interesting bookend plenary discussions for this post.  The opening plenary featured motivational speaker, Murray Banks; not to be confused with Matt Foley: “eating a steady diet of government cheese and living in a van down by the river”.  Actually, if triathlons and mountaineering were autoRead more

Last week in Pricing PV Energy, I discussed how solar photovoltaic, aka PV, aka rooftop solar, will not take down utilities or the grid.  The premise of that was once net metering policy pays PV owners what their electrons are worth in real time, the cost effectiveness will be capped, likely at some number consideredRead more
