Grid-Interactive Efficient Buildings

Demand Response Primer

By Energy Rant No Comments
Last week I described how net zero sounds grand, it’s easy to do, but it doesn’t work to support the transition to a clean-energy grid. The reason is that everyone, whether utilities or customers, overproduces simultaneously, and then later, customers all need energy from thermal power plants simultaneously. We have an exploding deficit of customers to take that overproduction and shift load or store it for use when intermittent renewable supplies shut down. In Renewables at Scale, I described how renewable supply and batteries would never be sufficient. The gaps in intermittent renewable supply are too big for batteries to…

Next Up: A Wild Energy Ride

By Energy Rant One Comment
It has been a frothy year for the energy industry, and it will continue well into next year and beyond. How far? Heh heh. Let’s start with coal. After plummeting 30% in 2020, consumption bounced back, gaining 35% in 2021. Doing the math, that doesn’t quite get coal back to 2019 consumption. Coal plants are still closing at a breakneck pace, so consumption in the United States is bound to decline in the long haul, but will load balancers and utilities be able to keep the lights on in 2030? This is a concern to me because no source of…

GEBs The Final Chapter – Baby Steps!

By Energy Rant No Comments
This is my sixth and final post on Grid-Interactive Efficient Buildings (GEBs), including the great interview with Doug Scott (#5) of the Great Plains Institute. This week, I will wrap up with a mishmash of items in the DOE’s GEB Roadmap. As I start this wrap-up, what I wrote three years ago comes to mind - How About Some D in DSM? Here is the gist as it applies to GEBs today: I have always found it interesting that “demand-side management,” the term that is generally used synonymously with energy efficiency programs, includes virtually no demand management whatsoever. The term…

Special Rant Vlog with Performance-Based Ratemaking Guru, Doug Scott

By Energy Rant No Comments
This week, we’re continuing our discussion on GEBs (Grid-Interactive Efficient Buildings) with our special guest Doug Scott. Doug is the Vice President of Strategic Initiatives at Great Plains Institute and is a great resource for performance-based ratemaking which is a key component of GEBs for both customers and utilities. Check out our fun conversation with Doug!

Grid-Interactive Efficient Buildings Part 4: Utilities Ask, Why?

By Energy Rant No Comments
This is the fourth in a series of posts on grid-interactive efficient buildings (GEBs). Here is a summary of the series: August 23 – Why GEBs? What is it, and why do it? August 31 – GEBs are difficult to achieve, beyond efficiency that should be done regardless. September 7 – What will customers think of this madness? Let’s peek at where we’ve been and where we are going. This series is based on a list of challenges noted in DOE's National Roadmap for Grid-interactive Efficient Buildings: Consumer awareness (Covered 07SEP21) Complexity (Covered 31AUG21) Utility interests (Today) Regulatory models Policymaker…

Grid-Interactive Buildings Part 3: Customer Perspectives

By Energy Rant No Comments
The first in this series of posts on grid-interactive efficient buildings (GEBs) described the intent of GEBs. The objective is to use buildings to shift, shave, or shed load to improve grid reliability without making expensive investments like peaker plants or electricity storage. Sounds great, but there is more than enough complexity to make that happen, and that is what we skimmed last week. The list of challenges as noted in DOE's National Roadmap for Grid-interactive Efficient Buildings is repeated below. We’ll attack the list from the top. Consumer awareness Complexity (Covered 31AUG21) Utility interests Regulatory models Policymaker ignorance Consumer…

Grid-Interactive Buildings Part 2 – Funny How?

By Energy Rant No Comments
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…

Phase Change Materials for Grid-Interactive Efficient Buildings (GEBs)!

By Energy Rant No Comments
Last week in Thermal Storage for Grid-Interactive Efficient Buildings (GEBs), I introduced the importance of phase changes from solid to liquid to vapor, and the reverse, to our modern world. Benefits include heating, cooling, and refrigeration for all types of uses, including space conditioning, food storage and transportation, healthcare, manufacturing, and of course, thermal storage. The simplest everyday thermal storage material is ice. Grocery and convenience companies have enormous ice-making facilities for guess what: thermal storage and your lowly Igloo or swanky Yeti coolers. I have a Coleman Lil Oscar cooler that I’ve used since Ha School. Now that is…

Thermal Storage for Grid-Interactive Efficient Buildings

By Energy Rant No Comments
Aside from efficiency being a core component of my thermos-fluids courses in engineering school, phase changes were also captivating to me. Phase changes from solid (ice) to liquid (water) to vapor (steam) have been used for hundreds of years, and more recently, the last 150 years, give or take, to generate electricity, refrigerate, freeze and keep us cool in the summer heat. Like water, practically anything will freeze, melt or vaporize. Take copper, please. It is widely used to conduct electricity in homes and buildings. It too melts and vaporizes. When it vaporizes, you don’t want to be near it…
