The
Dawn Of The Great California Energy Crash

California,
which imports over 25% of its electricity from out of state, is in no
position to lose half (!) of its entire nuclear power capacity. But
that’s exactly what happened earlier this year, when the San Onofre
plant in north San Diego County unexpectedly went offline. The loss
only worsens the broad energy deficit that has made California the
most dependent state in the country on expensive, out-of-state power.
Its
two nuclear plants -- San Onofre in the south and Diablo Canyon on
the central coast -- together have provided more than 15% of the
electricity supply that California generates for itself, before
imports. But now there is the prospect that San Onofre will never
reopen.
Will
California now find that it must import as much as 30% of its power?
The
problem of California’s energy dependency has been decades in the
making. And it’s not just its electrical power balance that
presents an ongoing challenge. California’s oil production peaked
in 1985. And despite ongoing gains in energy efficiency via admirably
wise regulation, the state’s population and aggregate energy
consumption has completely overrun supply.
Some
will say, however, that California doesn’t need to concern itself
with domestic energy production. As an innovation
economy,
in the manner of Japan or South Korea, many have said California can
simply import greater and greater quantities of energy in exchange
for its intellectual capital and the services and products it
provides to the world. But the problem with such a notion is that
it extrapolates
the trend too far.
Only
a century ago, California was an emerging giant of oil and gas
production, building much of its wealth from natural resource
extraction. It was inevitable that this would change over time.
However, given the state’s high priced electricity, its wrongly
devised transportation system (which is heavily exposed to oil
prices), and its deep financial distress, the nation’s largest
economy is having to exchange greater amounts of capital to keep
itself running.
Indeed,
the latest data shows that California energy production from all
sources -- oil and gas, nuclear, hydro, and renewables -- has just
hit new, 50-year lows:
California’s Great Energy Crash: State Energy Supply at Fifty-Year Lows
Since
1985 (the year that state oil production peaked above one million
barrels a day), the state of California has seen its portfolio of
energy production steadily decline, from an all- time high above
3,600 trillion BTU (British
Thermal Units) to
2,500 trillion BTU (latest available data is through 2010). Because
the contribution from both nuclear and renewables during that period
has been either small or simply flat, the steady decay of
California’s oil and natural gas production has sent the state’s
energy production to 50-year lows.
However,
during those five decades from 1960 to 2010, California’s
population more than doubled, from nearly 16 million to nearly 38
million people.
Additionally,
California built out its freeway system and expanded greatly into
counties such as Riverside and San Bernardino. Indeed, in San
Bernardino County, population quadrupled from 1960 to 2010, from five
hundred thousand to over two million, with the attendant homes,
public infrastructure, state highways, and freeways.
This
great expansion of California’s residential and industrial
topography was a tremendous value proposition back when energy,
especially oil, was cheap. But now we are in a new pricing era for
oil. Equally, California must also pay some of the highest
electricity rates in the country. In counterpoint to the dreams of
energy conservation, while California’s population merely doubled,
its electricity demand rose nearly fivefold,
from 57 million KWh in 1960 to 258 million KWh in 2010.
Essentially,
California, like the rest of the country, has built a very expensive
system of transport, which is now aging along with its powergrid.
Surely
in the forty years that followed 1960, the prospect that California
would have to import greater quantities of fossil fuels and
electricity was no cause for alarm. However, the capital that is now
required each year to maintain its aging highway system and purchase
out-of-state oil and electricity, is mounting. While it’s true that
California’s GDP is mighty and ranks as the 8th largest in the
world, it’s also true that even smaller US states have seen their
energy production not fall, but rather advance, in the era of
higher-priced energy. Surprisingly, California’s total energy
production is now lower
than Pennsylvania’s,
which is an intriguing contrast given that the Keystone State figures
so prominently in the history of early oil and coal production.
Who
will produce all the energy that California will need to buy in the
future?
Golden State Hit by Nuclear Power's Inherent Complexity
In
the wake of the Fukushima disaster, a number of countries and
communities are reassessing the risk and the cost of nuclear power.
Overall, however, it is the aggregate complexity of
nuclear power that is driving the global stagnation and now the
decline of this particular source of energy.
The
complexity of nuclear power -- its enormous expense, its dependence
on government financing, its long construction timeline, and its
perceived and actual risk -- means that bringing new plants online is
ploddingly slow and aging plants are increasingly likely to see their
licenses rejected for renewal. From a recent LA Times
article, California
energy officials plan for life without San Onofre:
California energy officials are beginning to plan for the possibility of a long-range future without the San Onofre nuclear power plant. The plant's unexpected, nearly five-month outage has had officials scrambling to replace its power this summer and has become a wild card in already complicated discussions about the state's energy future. That long-range planning process already involves dealing with the possible repercussions of climate change, a mandate to boost the state's use of renewable sources to 33% of the energy supply by 2020 and another mandate to phase out a process known as once-through cooling, which uses ocean water to cool coastal power plants, that will probably take some other plants out of service. "Some of the weaknesses we have in the infrastructure [of Southern California] are laid bare by San Onofre," said Steve Berberich, chief executive of the California Independent System Operator, the nonprofit that oversees most of the state's energy grid... Before the current shutdown at the plant, officials had planned only for a scenario in which one of the reactors would be off line. No one had anticipated a complete shutdown. The plant's 2,200 megawatts of power provide electricity to about 1.4 million homes, but the facility also provides voltage support to the transmission system that allows power to be imported from elsewhere to the region San Onofre serves, particularly San Diego
.
San
Onofre’s processing ability has been damaged by faulty computer
modeling, which caused excessive and accelerated wear in its steam
generator tubes. The cost and timeframe for a solution may be so
great that the return on such an investment may not be worth it. But
again, note the complexity involved here, which runs the spectrum
from computer programming that guides the reactors' operation to the
critical role that this southern California power source plays in the
grid. In powergrids, nuclear power plants play an infrastructural
role but are also critically dependent on receiving power from
elsewhere in the grid. As Japan discovered, its own power plant
structurally survived the tsunami but failed when it
lost external power.
In
2010, the year for which the latest data is available, California
consumed 258,531 million KWh (kilowatt hours). 26% of that total was
imported mostly from other US states (54,406 million KWh) and a small
amount came from Mexico. California’s two nuclear plants provided
32,200 million KWh, about 12% of the total power that the state
consumes from all sources.
Roughly
speaking (because supply, demand, and capacity fluctuate from year to
year), the loss of San Onofre will increase California’s potential
dependency on out of state power by at least another 5%. This will
indeed push out-of-state power dependency to 30%.
California’s Soaring Oil Dependency
California,
like Texas, has been a giant in the history of US oil production. But
after reaching a peak rate of production in 1985-86 at around 1.1
million barrels per day, California now produces half that amount, at
540 thousand barrels per day.
Just
as in other post-peak producing regions of the world, such as Mexico
and the North Sea, there is a constant flow of hope and theorizing
that once again California could increase its oil production. While
it’s true that opening offshore blocks
to development could eventually stabilize and possibly raise the
state’s aggregate production, it is highly unlikely that onshore
production can now be moved higher. The reason is that best
technology practices are already well-deployed in California's
onshore production -- where old, original fields continue to produce,
but at much lower rates.
More
important is that California now has over 35 million registered
vehicles, nearly matching its population. That makes California
automobile rich but public-transit poor, as the state remains highly
leveraged to gasoline.
Indeed,
the post-war buildout of California followed the low-density,
urban-sprawl model that was replicated throughout the nation after
1950. Accordingly, cities like Los Angeles are having to make a
Herculean effort to resurrect a light rail system (built on the grid
of its historic trolley network, once the largest in the world).
But
60 years of automobile-driven development will not be undone easily.
The state is already spending a disproportionate amount of capital
each year just to maintain the existing highway system (an issue we
will explore in Part II of this article). And despite that ongoing
investment, Californians drive on roads with some of the poorest
conditions in the country.
Let's
take a look at the history of California's oil production against its
historical consumption of gasoline:
The
spread between the quantity of oil produced in California and the
quantity of gasoline consumed started to blow out in the mid 1980s,
when gasoline consumption rose above oil production as measured in
BTUs. Many believed this to be sustainable. But as the rest of the
country would discover, a price revolution in oil would eventually
hurt the economy very badly -- and, consequently, oil consumption. In
BTU terms, the difference between production of oil and consumption
of gasoline reached its widest in 2006-2007, when annual consumption
was running above 1,900 trillion BTUs and oil production at 1,250
trillion BTUs.
Now
consumption, like production, is falling. Will consumption follow
production downward, relentlessly?
The
prospect that petrol consumption has peaked in California, along with
the rest of the United States, is exciting if one is viewing such a
transition through the lens of efficiency, sustainability, and
post-industrialism. However, the dream of a non-industrial economy,
like all good ideas, reaches a terminus when we consider that a
majority of human services and products are still delivered and
produced through physical processes. The State of California does not
deliver state transportation, health care, education, police and fire
protection, and public works digitally through the Internet. Instead,
energy, delivered through tangible infrastructure, is required to run
the Golden State.
In Part
II: California: The Bellwether for the Rest of America,
we take a look at the severely-pressured state budget of California,
as well as other measurements of its economy indicating that the
direction of its energy balance is entering dire territory. What
exactly is the cost of California's energy consumption? And what does
it mean, as companies like Facebook build
data centers outside the country to
access external sources of electricity, that California cities such
as Stockton declare
bankruptcy?
There
is no miracle solution for California. Even if we assume that the
country continues to enjoy cheap natural gas prices, the cost of
imported electricity from NG-fired power generation will not fall,
because the cost of electricity transmission will continue to rise as
the grid ages and requires new investment. Eventually the price level
of higher energy and lower quality public services will also catch up
even to higher wage employees, because a hollowing-out effect is
going to pare down the number of service providers -- teachers,
merchants, construction workers, and even health care professionals
and lawyers.
Such
woes, however, are not unique in any way to California. They are
shared by most US states right now; California is simply further down
the timeline at this point. The key question here is what
are the steps Californians (and the rest of us) should be taking?
