NMEC Hedgehogs and Straw Dogs

By Energy Rant No Comments
As the third in a series, we are going to wrap up the normalized metered energy consumption (NMEC) protocol groundwork this week. See the first and second posts to catch up in case you missed those. The first post covered new construction programs for which NMEC doesn’t apply because a baseline of normalized energy use is needed for NMEC. The first post introduced non-routine events (NREs), which are random and not accounted for in any model. The second post explained that NMEC is ideal for residential behavior and weatherization programs. The second post explained that because of several specific NRE…

NMEC Jedi and NRE Troopers

In theory, normalized metered energy consumption, or NMEC, would allow demand-side resources, whether dispatchable (demand response) or non-dispatchable (efficiency, demand rates, time of use, peak rates, etc.), to be precisely measured with equipment customers have already paid for – smart meters and the advanced metering infrastructure. It would work like this: What does the meter say before intervention (like a bathroom scale)? What does it say after intervention? The difference of the two is the resource. What could go wrong? Plenty. Last week I suggested we need protocols and not just user’s manuals for deploying NMEC. This week, I deliver…

NMEC and Routine Monkey Wrenches

Normalized metered energy consumption, or NMEC, is another name for the nerdy term, EM&V 2.0. Why the switch? Maybe en-meck spills out of the mouth a little easier. Maybe EM&V 2.0 got the bad rap it deserved as I explained a couple years ago in Whale Bus or Airbus and Automated M&V in Your Dreams. We need not only the user's manuals for how to deploy NMEC; we need protocols for how to apply NMEC, where it works well, and where it doesn’t. NMEC Explained The following would never happen, but I need a way to explain how NMEC works…
