[Episode #174] – Decarbonizing Britain’s Grid

As the energy transition proceeds and variable renewable power from wind and solar displaces conventional generators, strict operational limits for the grid's voltage, frequency, and inertia must be maintained. To do this, grid operators are increasingly procuring so-called “stability services” and making other enhancements to the grid that ensure stability.

In this episode, we take a close look at how Great Britain is undertaking this stability challenge by interviewing Julian Leslie, Head of Networks and Chief Engineer at National Grid ESO, which runs the transmission grid for the country. Not only does National Grid ESO operate the fastest-decarbonizing electricity network in the world, it has also recently achieved several important technical accomplishments for the first time in the world, including implementing cutting edge tools that allow accurate measurements of inertia across its system; using grid-forming inverters to provide synthetic inertia; and using synchronous condensers without an associated prime mover. And in another world-first achievement, the company has actually written the specification for using grid-forming inverters into its grid code.

Julian explains all of these technical concepts in today’s conversation and lays out the deliberate strategy that the company is taking to ensure that it can deliver on Great Britain’s decarbonization objectives while maintaining system stability and saving British consumers a great deal of money.

This is a highly technical episode with a Geek Rating of 9, so if you want to brush up on grid power engineering concepts first before listening to this one, you could start with our Energy Basics miniseries—in particular, Episode #126 about how power generators and the grid works—then move on to Episode #55 on voltage stability, and then Episode #153 on grid-forming inverters. Then return to this one.

[Episode #158] – Global Energy Crunch

Since early July, a global energy crunch has unfolded, driving up prices for all energy fuels around the world, and then causing some power plants and manufacturing facilities to shut down. In turn, that has exacerbated problems across global supply chains, causing major delays and price increases for everything from gasoline to hard goods.

If you have been wondering why your heating bill is up, or your last tank of gasoline was so expensive, or why your local retailer is telling you that you’ll have to wait months for that new washing machine, this episode will give you at least the beginning of some answers. These are remarkable times in the energy markets, unlike anything that’s happened since the last major commodity spike of 2008.

And we are very pleased to have an analyst and editor who has been following energy and commodities since well before that last spike as our guide in this episode: Will Kennedy, executive editor for energy and commodities at Bloomberg News. Will leads us through the many, many facets of this complex picture, and then we wrap up the conversation by asking how the world’s energy leaders will respond to it as the COP 26 climate conference gets underway. This developing supply shock may give us a good clue about how the world responds to the challenges of the energy transition in the coming years.
