Testimony before the California State
Assembly Utilities and Commerce Committee Informational Hearing on
Implementation of the California Solar Initiative
Bernadette Del Chiaro, Clean Energy Advocate

October 30, 2007
Dear
Chairman Levine and members of the committee. Thank you for the
opportunity to testify before you today on the implementation of the
California Solar Initiative.
Environment California Research
& Policy Center applauds this committee’s leadership in promoting
clean renewable energy, and solar power in particular. With the recent
passage of both SB 1 (Murray), the Million Solar Roofs Initiative in
2006 and AB 1470 (Huffman), the Solar Water Heating and Efficiency Act
of 2007, California has become a world leader in making solar power a
mainstream energy resource for all to enjoy.
Environment
California Research & Policy Center is a statewide, nonprofit,
nonpartisan environmental organization Along with our sister 501(c)(4)
organization, Environment California - the sponsor of both SB 1 and AB
1470 – we strongly support California’s landmark solar initiatives.
Ten
months after the launch of the California Solar Initiative, it is our
opinion that the program is, by and large, going well. California is
not only home to the largest market for solar power in the country but
this program in particular is one of the most exciting and successful
ones anywhere in the world.
In just ten months, California has
seen 160 megawatts (MW) of distributed solar power applications filed
through the California Solar Initiative at the Public Utilities
Commission (PUC). In addition, we’ve seen a growth in the number of new
housing developments incorporating solar power as a standard feature.
To put this amount of solar power in perspective, a typical natural
gas-fired peaking power plant is between 50-75 MW. This means that in
just ten months – a far shorter time frame than any fossil fuel power
plant can achieve – California is close to installing the equivalent of
two peaking power plants.
It is important to note that this
program is not only good for the environment, reducing global warming
pollution and smog-forming pollutants, but it is also good for all
ratepayers whether they participate in the solar program or not. This
is because it is cheaper for ratepayers to subsidize the private
investment in roof-top solar power than it is to purchase fossil-fuel
powered electricity. In other words, the California Solar Initiative is
a win-win for the environment and for ratepayers.
My comments today will be brief and will touch upon three major points:
1.
California’s legislative leaders need to play a role in clarifying the
proper mindset when it comes to implementing California’s
precedent-setting solar programs;
2. There is a need for
California’s policy makers to distinguish between growing pains
experienced as a result of these two historic programs getting off the
ground, and true roadblocks to our future success in building a million
solar roofs in ten years;
3. And, the state legislature
should focus on removing all remaining roadblocks to California’s
million solar roofs goal as well as creating “on ramps” that can help
ensure our future success.
Mindset Issues
Upon
observing the implementation of the California Solar Initiative over
the past ten months, there are three main mindset issues that need
clarification.
These three are:
a) SB 1 and the
California Solar Initiative are not “green building” initiatives.
Instead, they are market transformation initiatives setting out to
create a market large enough to drive down the price of solar power and
create a mainstream, self-sufficient solar market within ten years.
That said, SB 1 does envision a program in which complementary energy
efficiency measures are incorporated into the program. But there has to
be a balance between the solar goals and energy efficiency. Energy
efficiency should be coupled with solar power but not at the expense of
growing a mainstream solar market.
b) In order to achieve the
goal of creating a mainstream, self-sufficient solar market, SB 1 sets
two specific goals of 1) building both a million solar roofs and 2)
installing 3,000 MW of solar power within ten years. The assumption is
that the average system size is 3 kilowatts (kW) which, when multiplied
by a million, equals 3,000 MW. It is important to remember these two
concurrent goals because without both of them being more or less met by
2017, California might fail to achieve its overarching market
transformation goal.
For example, if California were to only
pay attention to the 3,000 MW goal, we could see market growth mostly
in the commercial sector. Instead of adding a million solar roofs or
our existing 25,000 solar roofs, we might add only 10,000 solar roofs
each with a 300 kW system. In contrast, adding a million solar roofs to
our existing 25,000 solar roofs increases our market 33x. Of course,
the actual growth will not be exact. It is possible that California
will ultimately see the addition of 900,000 solar roofs with an average
system size of 3.3 kW. Or, conversely, we could see the addition of
1,100,000 solar roofs with an average system size of 2.7 kW. The point
is California needs robust growth in both the residential and
commercial sectors and that the two goals of capacity and number of
roofs are equally important.
c) Administration of the
California Solar Initiative is a privilege and expectations for
successful implementation should be high and evaluation rigorous. Right
now, implementation is being overseen by the Public Utilities
Commission but the actual administration is being handled by the
state’s investor-owned utilities or their subcontractors (as is the
case in San Diego). This set up makes sense in a number of ways and
could work but it shouldn’t be assumed that this is the only way to
administer this critically important program. Administration privileges
should be revoked if the utilities are not aggressively, proactively
and effectively meeting California’s goals.
Growing Pains vs. Roadblocks
California
has embarked on the nation’s biggest and longest-term solar rebate
program. This historic new initiative is bound to experience some
hiccups, growing pains, and minor mistakes within the first year of
implementation. Many of these “growing pains” are being addressed by
the PUC and program administrators. Some still need attention. The good
news is there seems to be a descent forum for communication between
solar installers, administrators, PUC staff and the public. The
legislature should continue to ensure rough spots are being ironed out.
This
said, the California Solar Initiative still faces some serious
roadblocks that must be addressed by the legislature, the PUC and
Congress. These roadblocks were either written into SB 1, with the
assumption that the legislature would come back to them in the coming
years, or they were simply not addressed by SB 1 at all.
They include:
a)
Time of Use Rates – Mandatory Time of Use rates for all solar
installations is a serious roadblock to the emergence of a mainstream,
cost-effective solar market. Until Time of Use rates are mandatory for
all ratepayers it should remain an option for solar customers. The
emergency bill passed and signed last spring to delay mandatory Time of
Use rates for all solar installations buys some time but the roadblock
remains. In fact, it is anticipated that this problem will flare up in
Edison territory as soon as 2009. This means that the legislature must
remove the mandatory Time-of-Use rate requirement in 2008 if it is to
avoid another emergency situation in 2009.
b) Net Metering
Cap – To build a million solar roofs in California, the cap on net
metering must be lifted to at least 5%. The current 2.5% cap in SB 1
leaves only enough room for around 1500 MW of solar power, if not less
in some utility territories. Under projections for solar growth under
the California Solar Initiative, this 2.5% cap is likely to be hit
sometime around 2009/2010.
c) Rate Structure – Electric rates
and rate structure have a tremendous impact on the viability of going
solar. The main reason why PG&E is seeing more solar installed than
Southern California Edison, for example, is not because northern
Californians are more “green”, it is because PG&E has a rate
structure that favors energy efficiency and grid-tied solar power.
Edison is installing less solar than PG&E even though they have a
larger territory with more sunshine. This can be fixed by changing
Edison’s rate structure.
d) Federal Tax Credits – SB 1 and
the California Solar Initiative assume that the federal government will
extend federal tax credits for solar power out ten years. Without these
tax credits, the California Solar Initiative will remain in pace, but a
much higher rebate will be needed to make solar a cost-effective
investment for consumers.
In other words, without the federal tax
credit, we would not likely get 3,000 MW out of our $3.2 billion
investment. In fact, it is quite possible that we’d get almost half as
much solar power for the same amount of money. To be clear, this is
because the math used to set the size of the California rebate assumes
the continued existence of the federal tax credit. Together, they shave
off about 50% of the cost of going solar. Without the tax credit, the
California rebate would have to be higher, meaning less solar for our
confined pot of money.
Solar On Ramps
Mindset
issues and roadblocks aside, it is also important that California
continue to ease the way for consumers to invest in solar power.
Growing our state market from 25,000 solar roofs to 1,000,000 solar
roofs in ten years, is going to take a lot of effort. SB 1 and the
California Solar Initiative are great starts and, with the above
roadblocks removed, are likely to get us there within the 10-year
timeframe. With some additional on-ramps added, however, California
could be given greater assurance of success on a
faster timeline.
There are many “on ramps” that could be added to California’s statewide
solar program. Some of the most promising include:
a) Excess
Credit Buy-back – One of the biggest complaints I hear from the public
is that the utilities get all their excess credits for free at the end
of the year. While net metering allows a homeowner to accrue credits
throughout the year to offset electricity used during the night or when
the sun is not shining brightly, at the end of the year if excess
credits exist (e.g. if the homeowner generated overall more electricity
with their solar system during the year than they consumed), they are
zeroed out and the utility “gets them” for free. This unfair dynamic
leads to some “bad mouthing” of the program where a solar system owner
tells their friends and family that it is a big rip off because the
utility takes away their solar power for free. It also discourages
greater energy efficiency and conservation. While the wrong attitude,
many people are so irked by this that they seek only to “zero” out
their bill as opposed to taking additional measures to lower their
energy consumption beyond simply investing in a solar system. One
simple way to address this problem is to require the utilities to buy
any excess credits at the end of the year for some set price that
accounted for transmission and distribution costs but valued the solar
electricity as a peak resource. Such a policy change would require
legislation.
b) Multi-family/Multi-site Installations –
Currently, the California Solar Initiative favors single-family homes
and single occupancy commercial buildings. Sites with one roof and one
utility contract. While the vast majority of solar roofs are going to
be as such, there are a number of buildings in California that are
occupied by more than one utility customer and that should be allowed
into the program without any difficulty. A bill, AB 1223 (Arambula)
would have addressed one angle of this problem – the fact that farmers
have multiple electricity demands on one contiguous piece of property
and should be able to install one solar system to offset electricity
used throughout their farm. This bill did not pass the legislature last
year but should be reconsidered. Furthermore, there are a number of
neighborhoods in California where the individual roofs of a home are
shaded with trees and therefore not suitable for solar. However, if
these homes were able to pool their resources and purchase a joint
solar system, placed in some nearby location and tied to their meters
at home, they could participate equally in the million solar roofs
program.
c) Creative Financing Mechanisms – For many
consumers, paying upfront for a solar system is not an option. Instead,
their options right now are limited to mortgages or home equity loans
as a way to finance the $10,000+ upfront investment. There are many
ways that California can provide alternative financing mechanisms for
consumers, including in-bill financing through utility bills, financing
through tax bills (such as has been recently set up in the City of
Berkeley), or state-backed loans with lower or zero percent interest
rates.
Thank you again for the opportunity to submit these
comments. We greatly appreciate the legislature’s vigilance in ensuring
California’s historic million solar roofs program gets off the ground
and that we succeed in realizing the vision of making solar power a
mainstream, cost-effective energy resource for all Californians to
enjoy. I’d be more than happy to meet with you to discuss these issues
further at any time. I can be reached at 916-446-8062 x 103 or by email
