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…

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…

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…

AMI, or advanced metering infrastructure, is rolling out across the land. This opens the door to a lot of cool things, including time of use rates, and it is a great enabler of electrification technologies. I’ve heard from utility executives or people involved with some portion of demand-side management departments within utilities that smart meters are a waste of money. Wow. They are going to be standing at the depot while the electrification train is barreling forward. I will save that topic for another day. Stay tuned. For background, here is a primer on AMI and here is a discussion…
