Published in December 2021, Freeing Energy explores the concept of our energy grid inevitably evolving in the same way that computers and the internet did – with local solar and battery storage replacing large-scale, centralized power plants as the most reliable and economical option, much in the same way personal computers and the invention of the cloud eclipsed existing mainframe technology. Using another metaphor, from the spoke-and-wheel to the network.

The main tenants behind local energy are relatively simple. Our current energy system, globally, but especially so in the United States, is outdated. Few argue this point. It was developed during a time when the idea of being able to power one’s home was novel, and when building large, centralized power stations was the most cost-effective and reliable way to deliver that power.

It’s an idea that Bill calls “Big Grid” in the same way that one may lump Google, Meta, and Amazon together as “Big Tech.” In Freeing Energy, the Big Grid serves as the energy transition’s antagonist, rather than the usual culprits of utilities or the regulators that oversee them. As Nussey sees it, while these actors may make contributions that stifle our transition to clean energy, their decisions are largely influenced by the need to operate in the system that they were made for: sustaining the Big Grid.

One of the core tenets of Freeing Energy is understanding that, unlike coal or natural gas, solar energy is a technology, not a fuel, meaning that it is more subject to rapid innovations and improvements, as well as dramatic cost reductions as production volume increases – also known as Wright’s Law, which open up supply chains and lower overall costs.

In a sense, instead of working as suppliers, utilities would begin to work as aggregators, marketplace management arms, and a marketplace platform. “They go from being Walmart to being eBay,” says Nussey, always quick with an analogy. “You can’t move into the future by saying ‘I don’t want utilities,’ you can’t make utilities go away. Society as we know it would collapse … There’s good reasons why utilities are separate corporations. They can access an amount of capital that nobody wants to be taxed to pay.”

Yesterday, grid-scale battery storage provided a peak of just over 2 gW to the California grid for the first time. (At least the first time I've seen.) Peak value was 2.026 gW at 19:25. The peak exceeded 1 gW for the first time just a few months ago.

I was surprised to see this change as Tesla was trying to grow its Solar business.


"Now Tesla is reducing the $500 award for solar roof referrals to match the award for solar panel installations.
The automaker updated the language on its referral program support page:

“Friends and family who order through your referral link can earn $300 for Solar Roof or Solar Panels upon permission to operate, while also reducing reliance on the grid and producing clean solar energy. You will earn $300 for each Solar Roof or Solar Panels referral.”
 
Hit Hard by High Energy Costs, Hawaii Looks to the Sun

A year ago, regulators in Hawaii created a performance-based system that rewards utility companies for quickly connecting rooftop solar and battery systems to the grid. Utilities can also earn more money by promoting energy efficiency. That has helped make the adversarial relationship between utilities and ratepayers more cooperative.

While Hawaii faces unique challenges, the state’s reliance on solar carries lessons for other states and countries looking to fight climate change and bring down energy costs. The state has increased the use of renewable energy in large part by getting electric utilities to accept rooftop solar rather than fight it, as energy companies in California, Florida and other states have been doing.

Kauai regularly produces 70 percent of its electricity from carbon-free sources. It expects to increase that to as much as 90 percent in 2025, after building a solar farm, batteries and a hydroelectric facility that operates as a giant battery. “We’re looking at a real 100 percent clean energy,” said David Bissell, chief executive of the Kauai Island Utility Cooperative. “Absent a tragic hurricane, I think we’ll be there within a decade.”

Following an outage, it could be far quicker to restore electricity with energy resources that are close to home rather than miles of transmission line away. In fact, many outages might be avoided altogether by configuring local resources into rugged microgrids. The National Renewable Energy Laboratory (NREL) is showing how to design such decentralized resilience using only renewable energy in the Department of Energy (DOE)-led project AURORA: Autonomous and Resilient Operation of Energy Systems with Renewables.
 


Enacted in 1950, the Defense Production Act allows the President to to direct private companies to prioritize orders from the federal government and allocate materials, services, and facilities for the purpose of national defense. The order has been invoked twice since the beginning of 2020, once by then-President Donald Trump and again by Biden, in response to the Covid-19 pandemic. Invoking the Act will not end the DOC investigation, which is expected to continue, meaning that tariffs could still be imposed after the moratorium, depending on DOC’s ruling. However, according Reuter’s unnamed source, the impending action would eliminate the possible imposition of retroactive tariff collection, which could have gone as far back as the date of Auxin Solar’s initial petition filing.

Very much needed.

Each 1G of PV at 24% CF is 2.1TWh/year (365 days) and we really need as much of it as possible to avoid natural gas generation.

In the recently released report “States of Distributed Solar,” Institute for Local Self Reliance (ILSR) researcher Maria McCoy looks at which states have the most small-scale solar. States with the greatest capacity have more than 300 watts of rooftop and community solar per capita. In 2021, a record 18.2 GW of solar generation capacity was installed in the United States. Of that total, 5.4 GW was distributed solar, including a record 500,000 homeowners who installed residential solar systems.

Each 1G of PV at 24% CF is 2.1TWh/year (365 days) and we really need as much of it as possible to avoid natural gas generation.
For reference, the USA's total rolling 12 month generation to March 2022 was 4,159 TWh, so 1GW displaces only about 0.05% of generation.

The demand has been relatively stable, but if we want to add EVs we want to see increased demand.

However, 12 months through March 2022 12.76GW of PV were added (~0.63%) and the next 12 months 20.8GW are/were planned (~1%). Combined with new wind (although only 8.3GW) and the 5GW of planned new battery storage, a noticeable dent is certainly possible.
 
Good analysis of the financial benefits of residential solar.



It’s safe to say that electricity rates will continue to follow historical trends and rise in the future, so securing a rate for long-term clarity may be one of the best reasons to install residential solar.

(My own experience is that I have secured about 80% of my electric supply for the next 25 years at 7 cents/kWh. It's free after that.)
