Last week in the Opening Salvo, we studied the desired results of grid-interactive efficient buildings, aka GEBs. The desired outcomes include shaving, shifting, shaping, and shimmying electric loads to better match the supply provided by intermittent renewable supplies. This week, we’re going to examine barriers and difficulties on the way to these desired results, with solutions to come, of course. A single paragraph from the Executive Summary of DOE's National Roadmap for Grid-interactive Efficient Buildings provides plenty of fuel for this fire: Consumer adoption of this technology will require overcoming a lack of consumer awareness of participation incentives, mitigating perceived…

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 left field while everyone else is trying to make a pig fly. And when I see it, I think, “Wow, why did I not think of that?” The Roots of Sound Storage Thermal power generation, particularly from coal, and to a lesser extent, nuclear, have enormous…

Last week, we explored the state of EM&V 2.0 and its considerable, to say the least, constraints. This week, we look more intensely at fallacious “automated M&V”. Automated M&V is an oversold and over-hyped concept. When something is automated, it takes inputs (data) from various sources, often hundreds of sources, with high frequency, maybe by the second or on a Hertz (many times per second) scale. Then the brains of the automated doohickey compute and translate the data into solutions or outcomes. For buildings of all types, from single family homes to large commercial and industrial facilities, automated systems are…
