Energy Efficiency in a Land of Renewable Foie Gras

By Energy Rant No Comments
A couple weeks ago in Renewable Energy, Bad Parents, and Strawberries, I wrote that the value of an electrical generating resource depends a little on how cheaply it can produce energy (kWh), but a LOT on when and the (new word alert) dispatchability of the resource. For instance, California already has so much solar generation at the wrong time of day that it needs to dump kWh by paying producers to quit. This is demand response in reverse, or (new term alert) supply response. Yes, they are curtailing less than 1% of sales, but they are also two years ahead…

Evaluation, Measurement and Verification 2.0; A Whale Bus or an Airbus?

By Energy Rant 2 Comments
Evaluation, Measurement and Verification 2.0, or EM&V 2.0, is a nerdy term coined in 2014, according to this blog by Northeast Energy Efficiency Partnerships (NEEP). The hype of EM&V 2.0, which I will explain later, is that it will automate measurement and verification, putting us engineers out of business. This is not going to happen anytime soon. Definition 2.0 The definition of EM&V 2.0 boils down to using utility meter interval data, typically hourly or sometimes every 15 minutes, or maybe even 5 minutes, to disaggregate and measure impacts from energy efficiency measures. One could consider that EM&V 2.0 is…
