Capacity Market Poker

By Energy Rant No Comments
About two weeks ago, New England got a punch in the mouth from old man winter. I tuned into the Mt. Washington Observatory (New Hampshire) to check the conditions. On Friday evening, February 3, it was cool and breezy at minus 46°F with 99 mph wind and freezing fog. I dig that. Today’s post continues last week’s discussion on wholesale electricity markets, including capacity and energy-only markets. Summary of that post: Wholesale markets are headed for trouble because Electricity cannot and will not be stored in bulk quantities Society cannot function without electricity Grid loads are getting spikier, and that…

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…

Good, Perfect, and Real Carbon Targets – Finale

By Energy Rant No Comments
In this week's Energy Rant, we're covering the final segment of good, perfect, and real carbon targets.There are two sources of carbon-free energy. First, we have the category of renewable with wind, solar, hydro, and some geothermal. Second, we have nuclear. Oops – third, we have efficiency and demand management. The electricity market is bizarre to me. Last week I crudely explained how the regional transmission authorities (RTO) and their twins, independent system operators (ISO), balance the grid in real-time. Power supplied must match demand with very tight tolerances of voltage and frequency at all times. The chart below shows…

Good, Perfect, and Real Carbon Targets – Part 3

By Energy Rant No Comments
In this week's Energy Rant, we're covering part three of good, perfect, and real carbon targets.In Part I of this series, we examined how various storage technologies work, their pluses, and minuses. In Part II, we put numbers to generation and storage technologies, including maximum power, duration of discharge (for storage), cost per megawatt and megawatt-hour to build and operate, and a slew of other great stuff. In Part III, we will size up the numbers from Part II to actual grid demand. The objective is to provide scale to see what we would need to pair high percentages of…

The Rogue Choir Boy

By Energy Efficiency, Energy Rant, Government, Utility Stuff One Comment
I spent last week at the International Energy Program Evaluation Conference, IEPEC, as in, I-E-P-E-C to hard core evaluators or I-Peck for the rest of us. Ninety-five percent of the conference including content and networking was great.  Of course with this being the Energy Rant, I will beat on the remaining 5%. Recapping, there are generally two portions of program evaluation: impact and process.  Impact evaluation, which is what we at Michaels do, involves the assessment of savings (impacts) programs achieve, including what the measure actually saves (gross savings) and what impact the program had on the savings (net savings). …
