Why is California Blaming Wildfires on a Small Percentage of Downed Power Lines? (Part I)

“California’s reliance on hydropower and proliferation of remote, centralized renewable energy plants; the mandated environmental mothballing of 19 coastal natural gas power plants located close to customers; redundant transmission lines for green power; and seasonal wind blasts, results in lethal blast-furnace-like wildfires that leave trees alone but incinerates houses.”

“California leaders and opinion-makers must first abandon their blame game and diagnose the problem more clearly than using clichés like ‘global warming,’ ‘Donald Trump,’ ‘greed’ or even ‘not enough clear cutting,’ if they are going to responsibly deal with the dangerous unintended consequences of de-modernizing its electric grid.”

A question arising out of California’s recent wave of wind-fanned wildfires, is why are public officials mainly attributing the cause to downed electric transmission lines that comprise less than ten percent of all the causes of such fires?  This only further obscures why there are larger and more lethal wildfires.

The average percent of wildfires by cause in California from 2011 to 2015 is: undetermined (24%), miscellaneous (18%), debris burning (14%), equipment use (8%), downed power lines (8%), vehicle fires (7%), arson (6%), lightning (6%), campfires (3%), playing with fire (1%), smoking (1%), not reported (4%).

Downed electric lines are the fifth highest cause of wildfires at 8 percent.  As the Professional Firefighters Association of California has stated: “there is no single cause of California’s fire risk, and there is no single cure”.

Conservative news commentators have accurately blamed environmentalists for inadequate clear-cutting of trees around electric transmission lines. Conversely, former governor Jerry Brown blames global warming and President Donald Trump.  

New governor Gavin Newsom blames “greed” of electric utilities, apparently ignorant that their profits are set by the Public Utilities Commission whose president was appointed by Newsom. But this is nonetheless shortsighted because 92 percent of fires are attributed to other than downed powerlines.

Clear cutting trees outside of powerlines for the other 92 percent of causes would result in a scorched earth policy and prohibitive costs.   

California
wildfires have become an ideological political football. Both sides do not
recognize that lethal wildfires are the unintended consequence of installing a
new “smart grid” into the electrical system and the green sprawl into
California’s wild lands.

Comparison to
Other States

Percentage
of California Wildfires from Downed Power Lines:

Downed power lines caused 3.4 percent of wildfires in Oregon from 2015 to 2018. Oregon has about the same amount of forest land but is not as urbanized as California, and thus, has a proportionately smaller electric grid.

Oregon’s fires are often left to burn because they don’t threaten human habitation. Most importantly, however, Oregon depends on more hydropower (50 percent) for its electricity than California (13.5 percent). And its electricity comes mostly from dams along the Columbia River.

Conversely, a significant amount (43.5%) of California’s power comes from remote mountainous lakes and dams in forested areas or from transmission lines that import power from other states that have to cross forested areas before reaching large cities.

Texas, which has the most wildfires per year and more forested land than California, has only 1.9 percent of land fires from downed power lines. This is despite that up until this year many of its cities were blocking the clear-cutting of trees around power lines. Texas has about two-thirds of the population of California but does not import 30-percent of its electricity over mountainous, forested areas to reduce smog as does California. Texas relies on only 1 percent hydropower.

“Once-Through
Cooling” Killed Coastal Power Plants

In 2010 California mandated the mothballing of 19 gas-generated electrical power plants, ostensibly to protect marine life. The shutdowns result from a ban on what is called “once-through cooling”. Steam-generating power plants are located along the coastline so the plants can use ocean water to cool its turbines and discharge warm water back into the ocean. These 19 power plants have to shut down or convert to expensive air-cooling systems. The location of these 19 coastal power plants and their service areas can be seen here.

What
the closure of these power plants has done is shift where electricity is
produced to remote, inland or out-of-state green power plants dependent on long-haul
power lines. In 2013 PG&E warned the state grid operator (ISO) of future
green power blackouts. Moreover, the shift to green power has required doubling
some transmission lines because solar and wind power are redundant power to
natural gas generated power.

The Blame Game

The
San
Jose Mercury News
blames failed regulatory oversight of electric
utilities by the California Public Utilities Commission (CPUC). It further asserts
that this may end up forcing new governor Gavin Newsom (D) out of office, just
as former governor Gray Davis was recalled in 2003 for botching the 2001 California
Energy Crisis. That crisis, again, was initially wrongly blamed on the
Texas-based Enron Corporation, which left the
California market after three weeks and never had enough market share to influence
power prices
. The popularized media paradigm that Enron caused the
energy crisis regardless of the facts otherwise is similar to the current
situation where media deflects blame for disasters from government. 

California’s
new governor has proposed that fire-bankrupted Pacific Gas and Electric (PG&E)
be broken up and municipalized.  Socializing
the power grid won’t solve the problem but it will spread the costs of damages
and deaths onto all Californians.  The largest
municipal power agency in California, The Sacramento Municipal Utilities
District (SMUD –10,473
miles of powerlines, 3,800 miles distribution lines, 73,000 trees pruned/year,
),
has not been immune from blackouts due to downed powerlines.  

The
California postmodern trend of locating housing in bucolic wilderness areas
near mountain passes where winds pour into valleys, culminated in the 2018 ironically-named
Paradise Fire where
the trees withstood the fire but the houses burned
, a reverse
neutron bomb. Thinning trees may not have much impact in such bizarre
situations.ss

California leaders and opinion-makers must first abandon their blame game and diagnose the problem more clearly than using clichés like “global warming”, “Donald Trump,” “greed” or even “not enough clear cutting,” if they are going to responsibly deal with the dangerous unintended consequences of de-modernizing its electric grid.
