Reporting from the Mid-America Regulatory Conference

By Energy Rant No Comments
I attended the Mid-America Regulator Conference in Minneapolis last week. This post features issues of the day presented by utilities, commissioners, intervenors, technology providers, and sundry stakeholders. Load Growth Back in the day, we canoed the rivers and streams of Northern Virginia, especially after significant rainfall, when the water was high and running fast, which made it interesting. Let's just say my canoeing skills would be the equivalent of graduating from the bunny slope on a ski resort. For the latter, I learned to snowplow to slow down, and for the former, don't take the paddle out of the water…

Unheard of – Two Factors Exacerbated Elliot Power Shortages

By Energy Rant No Comments
The Energy Rant features content you will not find anywhere else, and this week we have blazing examples featuring two unpublished (go ahead and look) contributions to the grid crisis of Christmas weekend 2022 and winter storm Elliot. A few weeks ago, Utility Dive reported that gas-fired generation represented 70% of the PJM unplanned outages during Elliot. That represented about a quarter of PJM’s capacity. The days of interest include Friday, December 23, and December 24. Here were the generation mixes for those days. Hmmm. What didn’t fail? Coal and Nuclear. Why? Because they each come with months of fuel…

The Roots of our AC Power Grid

By Energy Rant No Comments
A while back, a reader asked, “why don’t we switch to at least localized direct current power grids?” The simple answer is it would cost a fortune for both the utility and the consumer to change all distribution and consuming loads to take DC power. As I researched power factor, I recalled why we have an alternating current power grid in the first place. This is interesting and worth knowing, Rant Pack. With that, I apologize for making you wait another week to understand why power factor matters to energy efficiency, directly. A Short Story You know I can’t resist…

Atmospheric Cooling = Strong Tornadoes

By Energy Efficiency One Comment
We interrupt this rant for this special announcement.  Our cold spring in the northern plains is wreaking havoc in the form of tornadoes in the southern and middle parts of the country. I think the weather phenomena had a lot to do with my interest in mechanical engineering.  Growing up on the farm in the flatlands, I had seen a great many black clouds approaching on the horizon.  As they drew closer, they would either brighten to a lighter gray and rain, or they get ugly.  If the approach is led by a dark band of clouds followed by blue-green…
