Lithium battery production have been on a strong growth curve for many years and is poised for ten-fold increase development in the near term with support of the current administration and significant venture capital investments across the industry.

According to Gene Berdichevsky, CEO of Sila Nano, and formerly Tesla employee #7, there is currently about 285 GWh of annual production capacity for lithium batteries.  He states there is an additional 2000 GWh of production capacity under development that will be complete within the next 5 years.  Gene was recently interviewed by Shayle Kann on The Interchange.  Sila Nano is itself building a plant that will provide anode materials for up to 100 GWh of lithium batteries annually targeted for the EV market, and sufficient for about one million vehicles per year.  https://www.forbes.com/sites/alanohnsman/2021/01/26/sila-nano-hauls-in-590-million-to-make-materials-for-better-electric-car-batteries/

While we recognize there are issues with the procurement of lithium and other materials, there are groups addressing the issues currently, and it appears that the use of electric motors and lithium batteries is currently the best practice for all ground transportation, be it personal vehicles, freight, or rail.

Here at Power Trip and for all of us in Washington State, we are installing batteries, though there is still no economic impetus for batteries in conjunction with your solar array.  While the percentage of our clients that initially state they want batteries is increasing, after we conduct an analysis of their energy needs, we usually determine the most sensible path is to install as much solar as possible up to the amount of energy you use, make certain you are using an electric vehicle as much as possible rather than buying and burning gasoline, and make other improvements in energy efficiency and emergency preparedness prior to considering a lithium battery installation.

The Texas grid has lost about 35 MW of production capacity during a severe winter storm, and this has caused cascading outages for millions of people across service territories.  Texas is the largest energy producing state in the country.  This article from GTM lists some of the reasons and some of the history since the last severe storms and outages there 10 years ago.  I find GTM’s writing fact based and the right level of sophistication for my understanding and the time I have for issues in other areas.

I send sympathy to people suffering the hardest, and I understand many people have perished.

I have also seen the fossil fuel industry and their spokespeople using this event as an opportunity to tarnish wind and solar energy generation.  While natural gas, coal, and nuclear plant shut-downs have been responsible for twice as much of the outage as wind and solar plants coming off-line, some have still claimed this is an example of why we should not build more renewable energy plants.  It turns out not to be true.

https://abcnews.go.com/US/wireStory/texas-blackouts-fuel-false-claims-renewable-energy-75936319

We should pursue both utility scale and distributed generation of renewable energy sources, which will provide more reliability in the long run, and will reduce our contribution to greenhouse gasses and anthropogenic climate change, which appears to be contributing to greater and more unpredictable weather events, often in areas not accustomed to them, like Texas.

6.3 KW of Sunpower on the roof, on the Jefferson PUD grid in Port Townsend

by Andy Cochrane | Feb 17, 2021

As part of the $900 Billion COVID Relief Bill that was passed and signed at the end of December, the item that will most immediately affect our clients this year is the extension of the 26% ITC (Investment Tax Credit.)  It has been slated to decrease to 22% this year and expire next year, however we now have the 26% for this year and 2022, then 22% for 2023, then expiration.

SO – if you have been considering solar for your roof, there has never been a better time than right now!

There were other clean energy related aspects of the bill, and several policies that solar advocates have been working for that still need to be worked towards with the next administration.  Green Tech Media provides a nice summary here  https://www.greentechmedia.com/articles/read/what-renewable-energy-and-energy-storage-did-and-didnt-get-from-congress-this-week

We are looking forward to a very positive, very sunny year, and working hard every day to install as much local clean solar for our clients as possible.  Happy New Year to all.

5.25 KW Sunpower pv array on Clallam PUD grid in Sequim, Sept 2020

by Andy Cochrane | Dec 4, 2020

This statistic in itself is not new, and Solstice arrived at this number using simiilar methodolgy I have seen used to yield similar results in the past. They are considering homeownership, shade vs solar resource, credit worthiness, and local regulations.  Credit to their article, link is here –  https://solstice.us/solstice-blog/why-americans-cant-access-rooftop-solar/

Our original quick and easy estimate of houses with roofs that could install solar on the Olympic Peninsula came from our friend Jake Wade, who used to work for PSE.  He guessed that 1/3 of the homes were owner-occupied by people with good credit, and that 1/3 of the homes had a good sunny roof – yielding 1/9, or 11% of homes here being good candidates for solar arrays.  Other estimates often yield a slightly higher potential percentage.  Currently in Jefferson County, about 2% of all electrical meters are net metered, indicating we could increase the number of solar arrays by a factor of 5 to 10 times, and that is our goal.

Community Solar in WA – past and future

For the remaining ~80%, many people support the idea of Community Solar.  This is a structure in which many people buy shares of a large array, and get the proper credit on their electric bill, the benefit of whatever portion of the larger array they own.  Community Solar has seen a couple of iterations so far here in Washington State, neither of which was easy to put together.  We installed two such projects, one of which we developed ourselves, with a team of fantastic partners, all figuring it out as we went, hoping to develop a project design and manual that others could replicate.  While the project itself was a success (if we don’t count only dollars and not the time and value of countless hours of work on development, we will count that as education), we did learn that we didn’t think the laws and programs in place at the time supported healthy community solar projects, so did not accomplish our goals of developing a replicable project.  The second project was installed for Clallam PUD, and was their baby, well-executed.  We just helped promote a bit, and performed an inexpensive, efficient, aesthetic installation.

At this point, to my understanding of what is in place at the state level, any utility could develop a community solar project any time, and design the program and pricing as they see fit.  There are no special state incentives at this moment, and utilities are mainly tasked with providing reliable and inexpensive electricity, and they really focus on that which they should.  So it is not a surprise to me that we don’t see utilities developing new community solar projects at this moment.  There will be new and improved legislation proposed in Olympia in the spring, and this moment will require ingenuity to find positive paths towards some economic recovery – just exactly what is available in community solar programs.  We will let you know more about those efforts soon as they firm up.

Today – Solar for your Home

In the meanwhile, if you are one of the 20%-ers that has a good sunny roof on a home you own, and sufficient funds or credit to make this investment in your home, there has probably never been a better time to make that investment in solar.  There is a 26% federal tax credit available through the end of the year, next year it becomes 22%, and then gone after 2021.  In times of uncertainty, we know the sun will rise tomorrow and that investments in your self and your home are a safe and wise choice.

Globally, we are experiencing a significant disruption to the economy to which we had become accustomed, due to our response to the COVID-19 pandemic.  While the questions remain as to if and how we should go about resuming our previous businesses and consumer habits, we can view this moment as a great opportunity.  At an individual level, many people have expressed appreciation for the opportunity to leave behind some old habits, and embrace some of the aspects of life that have been foisted upon us, but which we find fulfilling.  Spending more time with family, working on our homes and in our gardens, and less time spent commuting are all some positive results that some people have experienced in the last several months.

As a country, we have not been taking care of many things, including our transportation infrastructure as well as we could have, and as a result, we find many bridges and highways are old and in poor condition.  We need to perform many seismic retrofits as we now better understand the dangers of earthquakes, and have better materials science available to us to build more resilient structures.  Many of our public buildings are aging and inefficient, and present great opportunity for us to re-invest in improvements which will result in greater energy efficiency and improved indoor air quality.

We also need to address our carbon emissions, and we are now in the position to greatly improve the cleanliness of our transportation and public infrastructure through electrification and clean renewable energy sources, mostly solar.  In our buildings, we will leave behind fossil fuel-based heat sources, and utilize highly efficient and clean electric heat pumps, in addition to improved insulation and windows, and greater understanding of passive solar opportunities to decrease energy needs and improve the quality of the work and living spaces inside.

Regarding transportation, we continue to see Electric Vehicles increase in the personal transportation market, and we are on the verge of seeing larger segments of the transportation market be addressed by EV’s – notably school buses, garbage trucks, and delivery vehicles (Amazon, UPS, and Federal Express).  These vehicles are ideal for EV technology since the start-stop nature of their driving maximizes the benefits of regenerative braking, wherein re-routing kinetic energy to battery charging slows the vehicle.  The retirement of our country’s diesel school bus fleet would be especially beneficial to our kids as it would decrease their exposure to harmful diesel emissions and particulates.

In summary – this is our opportunity – to invest in clean infrastructure and transportation by using the massive economic power of the federal government, which creates good jobs to assist with our economic recovery, and improves the environment and public health for generations to come by decreasing pollution and carbon emissions.

We urge you to let your representatives know that these are important decisions you want made on your behalf.  Please support candidates that understand and agree with these goals.

While our individual influence over the state and federal government policy may be frustratingly limited, the decisions that you do have within your control are regarding your own home and vehicles.  You may wish to consider a sensible EV for your personal transportation, and placing solar panels on your sunny roof to create clean local renewable energy.

Commissioner Waddell has made waves in stilled waters.  By questioning the goals and claims of a power industry trade organization which the Clallam PUD has long supported, Waddell has alienated the leadership of the Public Power Council and caused the expulsion of Clallam PUD from the group, incidentally saving the ratepayers the $22,597 in annual dues for this year.  Waddell has pointed out that there may be benefits to the removal of the four Lower Snake River dams through his involvement with Dam Sense, www.damsense.org.

Here in Jefferson County, our PUD is a current member of the Public Power Council, whose goal is the preserve and enhance the benefits of the Federal Columbia River Power System for it’s member utilities.

Public Power Council expels Clallam PUD

by Andy Cochrane | Jun 16, 2020

As I take a deep calming breath, and anticipate the day we bring our crew back to work and resume installing solar arrays, I am thinking about opportunities to do things better societally, not just resume exactly as we have done until now.  In the US, we strive to balance rewarding ingenuity and hard work, removing barriers for people to better themselves, while also taking care of those who struggle because of lack of access to opportunity, discrimination, disability, ill-health, or just plain bad luck.  Achieving this balance is one of the ideals my country holds.  That being said, we all recognize there is, and has always been, a significant inertia in the reality that the rich get richer, and the rest are sometimes left behind.  Removing the unfair advantages brought by wealth and privilege should be one of our collective goals when examining any policy, federally or locally.

So what does this mean in terms of access to clean energy?  There are two unfortunate examples of our failure to do this on my mind from recent conversations.

A friend from Bainbridge Island lives in a condo in downtown Winslow.  She works within 20 miles of her house and visits her parents here in Port Townsend a few times a month.  It is rare for her to need to drive more than 100 miles in a day.  She wants to trade in her existing aging car for a newer model, and she wants an electric vehicle for her and her young child.  I am a fan of Nissan Leafs, but there are now many excellent choices across a spectrum of price and range, and there is no doubt it would save her lots of money on gasoline (and decrease her personal carbon emissions.).  The challenge is that because she is not a homeowner, she does not have access to a dependably available EV charging location.  There are a couple of EV spots for recharging within a few blocks of her house, but even that distance is inconvenient when she has her child and perhaps groceries in the winter.  Ideally she needs the dependability of being able to charge when she needs to, close to home.  She has been doing a little on-the-ground research and sees that the equipment and spots are often occupied by another EV when she would park.  She does not feel comfortable with the prospect of having to park elsewhere when she gets home, and having to go back out to check the availability of the charging spot and move her car in the evening so its is full again in the morning.  Her workplace has one EV spot in the garage, but it also is often occupied by customers or other employees.

This is an example of how increasing our public investment in EV Service Equipment infrastructure, and incorporating requirements for EVSE spaces in new development would help provide fair access to clean electric vehicles to people who are not currently homeowners.  These are important policies we need to adopt now, since we have not already done so.  It is past time for this in my thinking.

Regarding the Community Solar Project here in Port Townsend, it appears that the current application submitted by Jefferson PUD to build a community solar array will not be approved in time for the project to come to fruition.  This is a great shame for many reasons.  Primarily it was the opportunity to utilize generous state funds for projects just like this in a way that would benefit our community, especially those who don’t own their own homes.  Are you seeing a trend here?  Homeowners that want access to clean solar energy generally have it installed on their own roof, provided it is not too shady.  Even in the case that someone doesn’t have immediate access to the cash for these projects, there is a significant federal tax credit, and also several sources of local credit unions offering low interest energy efficiency loans.  Access to solar is much more difficult for a renter or condo-dweller since they don’t own their own roof on which to install solar.  Community solar projects are common sense and economical ways to make the benefits of solar available to everybody in small slices.  People who are able to participate in community solar projects enjoy a long term economic benefit; these projects can help individuals and households hedge against rising energy costs while participating in the clean energy future most of us envision.  From my observation, it appears that some neighboring homeowners had objections to this project on an aesthetic basis, and successfully have prevented the project through active obstruction through the public permitting process.  The concept that an existing utility sub-station might not be an appropriate for a ground-mounted solar array is mind-boggling to me, but apparently the city staff is sympathetic to these views of some neighboring homeowners.  I am making a strong statement here, which would surely be vigorously disputed by some.  I would welcome respectful communication, and will gladly admit if I can be shown to be wrong.  The missed opportunity of about $110,000 of state funds, and our city’s failure to nurture this project is a loss for our community in many ways.

The pandemic we are currently experiencing, the concern over potential loss of lives, and our necessary short-term economic pain to try to prevent the worst losses, are bringing new perspectives to our values.  What do we truly deem important for our future?  The challenge of carbon emissions and the opportunities of cleaning our energy portfolio have not gone away while we have focused on more immediate concerns.  The past does not have to determine our future.  What steps can we take to build the world we want to emerge from this time of quiet disruption?  How can we make clean energy technology and its benefits available to all?
