Electric Ratemaking Basics and Load Flex

By Energy Rant No Comments
In the last two Rant posts, we explored dated benefit-cost tests for energy efficiency and demand response programs and introduced flaws with dated ratemaking schemes. Both constructs are based on a century-old “cost of service” business model for monopolistic utilities. In a nutshell, the cost of service includes the debt and equity financing of generation, transmission, distribution, and operations and maintenance, which includes employees, fuel, storm damage repair, and arboriculture. Add up all those costs, including competitive investor returns on equity and debt, and then smear those costs as equitably as possible across the customer base. The sum of those…

Reverse Efficiency Beatings with DRIPE

By Energy Rant No Comments
Does more industrial energy efficiency lower energy prices for all? That is a partial title of a paper published at the 2015 Summer Study on Energy Efficiency in Industryand the source of last week’s sassy DRIPE post ( DRIPE = demand reduction induced price effects). DRIPE is a measure of the value of efficiency delivered via downward pressure on energy prices, in this case, electricity prices. The ACEEE conference paper notes that industrial customers could help drive prices for everyone lower through greater demand response through real-time monitoring, smart technologies, and load visualization. This sounds like grid-interactive efficient buildings to…

An Appetizer Into DRIPE, the Main Course

By Energy Rant No Comments
What do you envision from the word dripe? I think of boiling cowhides as feedstock for collagen peptides in the manufacture of gelatins used for deserts or your favorite mascara or lipstick. I was close on both counts. The word is tripe (not dripe), which is cow stomach, rather than cowhide. The holidays are on the doorstep, and you need appetizers, right? You’re welcome. Visit your local butcher, get some tripe, and get cookin’! DRIPE, the acronym, is demand reduction induced price effects. Do ya think somebody was trying to create a catchy acronym? Result: cow stomach. This post introduces…

Savings Persistence – Funner than a Barrel of Monkeys

By Energy Rant No Comments
Today, let’s consider a subject that is as squishy, subjective, and amorphous as net savings and non-energy benefits (see here and here). Today’s subject is savings persistence. Savings Persistence and Its Importance Even allowing for generous latitude, if I polled readers of this post, I would probably get a dozen definitions of savings persistence. For retro-commissioning, persistence is ensuring the measures aren’t undone. For the broader group of behavior programs, persistence is getting customers and their occupants (family or employees) to continue to value and manage energy over the long term.To the evaluator, savings persistence opens many cans of worms.…
