Interview with smart grid expert Steve Pullins, part two

For nearly 30 years, Steve Pullins has worked in and around the utility industry, in capacities ranging from systems engineering to project development to high-level consulting. He currently works at SAIC, where he heads the Modern Grid Initiative for the National Energy Technology Laboratory. I spoke with him at the Discover Brilliant conference in Sep. […]

How high a price on carbon is needed to make renewables competitive?

I’ve argued before that electricity cost comparisons are, in Walt Patterson’s memorable phrase, "an artifact of prior decisions otherwise concealed" — i.e., based on unstated moral, social, and economic assumptions. Most of those assumptions, for reasons of habit, custom, and occasionally pecuniary interest, are weighted toward the traditional way of doing things: a hub-and-spoke electricity […]

CPR for the electric car

Project Better Place has a new take on jumpstarting the electrification of transportation: they've raised $200 million (about enough to buy, what, three fuel cell vehicles?) to start building infrastructure for charging and battery exchange stations.

That's just a down payment. If you play Internet Nancy Drew for a sec you will quickly find out that Israel Corp, a major investor, also has a stake in oil refineries, and 45 percent of Chery, the Chinese car company that keeps threatening to build electric cars. These guys are invested in the full value chain, and dollars to donuts they're leveraging much more value from partner companies than the measly $200 million. We are talking about a $6-10 trillion industry, after all, which tends to focus the mind and get people working together.

Do yourself a favor and check out the video. The vision is a transportation system powered by wind and sun. And a software exec (CEO and founder Shai Aggassi comes from SAP) is exactly the right person for the job.

We don't have an energy problem, we have an energy storage problem. When I listen to Agassi talk about developing software to manage the charging strategies of EV's flexible and mobile loads in a way that enhances integration of intermittent resources like solar and wind into the grid, I get a little weak in the knees.

Combine that with REC's announcement that it was building a 1.5 GW fully integrated solar manufacturing plant in Singapore, and the future seems much brighter indeed. Note that 1.5 GW was about the size of the entire world market in 2006.

The combination of cheap solar and millions of big batteries on the grid can mean only good things.

We need a grid as smart as our bombs

So much talk about new energy supplies ignores the wisdom we supposedly learned in the '70s about "negawatts" being the most efficient, effective, and environmentally friendly source of power around.

It's good to see that we might finally make some progress in this direction, learning to shave demand peaks and save a bundle (and open the way for integrating more renewables into the grid):

Solar thermal company says its generation/storage combo can power the nation

A new design for solar thermal electric generators could bust the technology out of niche status and supply the country’s entire electric load, according to … people who make solar thermal electric generators. … physicist David Mills, chief scientific officer and founder of Palo Alto, Calif.-based solar-thermal company Ausra, has bigger ideas: concentrating the sun’s […]

Who will lead on advancing smart-grid technologies?

To bring on the amounts of variable wind and solar energy and plug-in vehicles needed to meet our vast energy challenges, we will need a smart grid capable of managing much more complex power flows. Outside of some progressive exemplars, however, don't expect leadership to come from the utility sector. Instead, changes will be forced by new policies and players, including some you might not expect, like big box retailers.

Those were my key takeaways from the stellar line-up of smart grid speakers at the Discover Brilliant sustainable technology conference in Seattle this week. David has been blogging away from the conference, so I don't want to go over too much of the same turf. Instead I'm going to synthesize what I heard across a number of sessions and offer my interpretations.

A few statistics from the conference underscore the sluggishness of the electric utility industry when it comes to advanced technologies:

On electricity deregulation

In The Karate Kid, Mr. Miyagi advises that "It is good to know karate. It is good not to know karate. It is not good to know a little karate." With the price caps now coming off in the few states that partially deregulated their electricity grids, there is a rising backlash against competitive markets, with some of that backlash even coming from normally pro-market groups like The Cato Institute. This backlashers generally argue that partial deregulation has taught us that deregulation doesn't work in the electric sector. But we ought to remember Mr. Miyagi's advice, lest we draw the wrong lessons from our little bit of karate.

This subject deserves more discussion on Grist, as evidenced by some of the debate which followed my last post. Let's take a closer look.
