An Industry Starts to Pivot: Electric Utilities' Shifting Business Models in the Rise of Solar


Amory Lovins and Karl Rabago saw this coming a long time ago.

Now the Wall Street Journal (not Grist, not Mother Jones, not Rolling Stone) references the EEI distributed solar dispatch from earlier this year and runs with it. Not just early/first mover NRG, but the old guard is chiming in too: AEP, Duke, Southern Co, Nextera, Dominion, PG&E ... you get the
picture.

First up is Nick Akins, American Electric Power CEO:
On its face you would look at it and say distributed generation is a threat. But on the other hand we see it as an opportunity because our business is changing. There's no getting around it.
Other big utility CEOs join the chorus and soon the message is unmistakable.


Then from the Oxford-American we get a feature-length article laying out the whole new solar landscape including this comment on security:
Former CIA director James Woolsey is a big fan of small-scale distributed solar because he believes rooftop solar, linked by micro-grids, is a way to avoid a potentially catastrophic attack on our still very centralized electrical grid.
To many this still feels unreal. But to an ever increasing group of companies and customers who are experiencing the shift to distributed solar generation first-hand, it's fast becoming the new normal.

I generally concur with Woolsey's optimism, but will be exploring the potential security ramifications in more detail with industry colleagues soon and will report initial findings here. In the meantime, please pass the Bain de Soleil.

Energy Security Update: Renewables Economics Hitting German Utilities Hard


A week or so ago I posted about an EEI report warning that many if not most utilities are ill equipped to adapt to shifting business models arising from the build-out of distributed energy generation technologies.

In what some call a vicious cycle, the more technology allows customers to partially or fully remove their loads from the grid, the fewer payers there are to support the maintenance (let alone the modernization) of the grid's vast and aging infrastructure. I also asked readers to consider the implications for cybersecurity thinking and spending in the context of these types of mounting economic pressures.

Now I've got another article for you ...
this one is from Slate about Germany, land of the solar panel. And of the unexpected impacts pro-solar government policy has played, and what this all means to German (and US and global) utilities. Start here:
The proliferation of privately owned solar has large power companies in Germany worried. For two decades, they’ve been forced to facilitate and finance their competition, helping turn customers into producers.... Utility companies [were required] to plug all renewable power producers, down to the smallest rooftop solar panel, into the national grid and buy their power at a fixed, slightly above-market rate that guaranteed a modest return over the long term
The results of this policy, coupled with the increasing maturation of the enabling technologies, makes this intensity of this wave feel similar to recent industry-upending impacts of digital cameras on the century-old film photography business, and the many internet-triggered upheavals in media ... albeit perhaps in slower motion. 

No country has invested in and incentivized solar the way Germany has. Consider this:
The southern German state of Bavaria, population 12.5 million, has three photovoltaic panels per resident, which adds up to more installed solar capacity than in the entire United States.
If and until practical grid-scale energy storage arrives, there's going to be pressure on the status quo models there: 
 ... coal and nuclear plants—which can’t simply be switched on and off at will—must be kept running to guarantee a steady stream of electricity when the sun isn’t shining. That means overproduction of power during daylight hours, as the country’s ample solar energy floods onto the grid along with electricity produced by power plants. Power companies traditionally charge more during the day, when offices are full and manufacturing plants are in full swing, so the glut of daytime solar power reduces their profit.
And that's not the only source of pain:
The proliferation of solar panels on homes also takes high-margin residential customers off the grid at peak hours. And the energy surplus has driven prices for traditional coal and nuclear power down, even as renewables are still guaranteed more-than-competitive rates.
And the kicker:
As power companies try to pass the costs to consumers in the form of higher bills, that just encourages more people to put solar panels on their roofs.
The full Slate article can be read HERE.

Other countries, including certain regions in the US, are heading in this direction, though at a more measured pace than Germany.  But still, until a new model emerges, threats to the economic viability of utilities are a threat to the grid and therefore national and regional energy security. We've got to figure this out proactively  not re-actively.
