Electricity customers are lining up to generate their own clean, affordable solar energy, but to get it to them, solar developers must navigate the impediments of a congested and outdated electricity grid.

For this episode of the Local Energy Rules podcast, host John Farrell speaks with Yochi Zakai, attorney with Shute, Mahaly, and Weinberger representing Interstate Renewable Energy Council (IREC). The two discuss hosting capacity analysis and how publicly shared grid information can help solar developers, electric customers, and others make more informed decisions.

Listen to the full episode and explore more resources below — including a transcript and summary of the conversation.

Episode Transcript


Expensive Electric Accommodations

Electric distribution grids were built as top-down avenues for delivering electricity from large, centralized power plants. Now, as distributed generation and energy storage become more popular, utilities are having to accommodate the two-way flow of electricity. To do so, the utility often needs to upgrade the distribution system. This is especially true in areas where there is a lot of distributed energy development.

“The grid was built for this one way flow of electricity. But as more customers decide to install generation in their homes, the way that the distribution grid operates is also going to change.”

Solar developers looking to connect their new generation source to the grid may trigger the need for a system upgrade. In most cases, whoever triggers a grid upgrade must pay the upgrade costs — which can be severe. Larger solar gardens are more likely to trigger upgrades. If a developer is surprised by these costs, and building their solar garden is no longer feasible, they may be forced to drop their plans entirely. Hosting capacity analysis can provide key grid information proactively for individuals hoping to plug in.

Hosting Capacity Analysis

In a hosting capacity analysis, utilities compile information about the electric grid and publish it online for the use of developers and other stakeholders. The resulting map has pop-ups with data on various localized grid conditions: how much generating capacity that section of the grid can still handle, the voltage of the line, and the existing generation on that part of the grid.

This information, which Zakai calls “geeky grid data,” helps customers and solar developers make decisions.

“The studies produce a wealth of information that developers can use to cite and design the systems so they don’t trigger upgrades. And in some cases they can even make the grid more reliable.”

Utilities in seven states are required to publish hosting capacity maps. Some utilities even publish this information voluntarily. Zakai says that generally, hosting capacity analysis is most common in states with robust distributed energy development, including Hawaii, Massachusetts, and New York.

Some Truth to California Exceptionalism

California’s hosting capacity analysis process, called integration capacity analysis, provides more useful information than the hosting capacity maps published in other states. This is thanks, in part, to a petition from Zakai and the Interstate Renewable Energy Council (IREC). IREC asked the state of California to consider all kinds of interconnecting loads, including electric vehicle chargers, electric heat, and solar generating power, when implementing its integration capacity analysis. In January 2021, the California commission filed its petition to make changes to the analysis and its resulting map.

In California, grid users also uniquely share the cost of grid upgrades, rather than the typical ‘cost-causer pays’ model used in other states.

Automating & Simplifying the Interconnection Process

It is not possible to automate all new grid interconnections, says Zakai. Still, hosting capacity analysis could simplify many of the steps within this process. California is the first state in the country to try using hosting capacity analysis to reduce the complexity of the interconnection process.

“Hosting capacity analysis can be used to automate and increase the precision of some of the most problematic technical review processes that the utilities use when they evaluate new grid connections. Last fall, California became the first state in the country to make a final decision to use the hosting capacity analysis to automate some of these processes.”

Thanks to new rules adopted by the California Public Utilities Commission, solar developers can use the public hosting capacity maps to design and site projects with more certainty. As developers make more informed proposals, utilities will not waste resources reviewing projects that will never get built.

Tesla quietly removes range extender battery option on Cybertruck

Tesla quietly removes range extender battery option on Cybertruck

Tesla has quietly removed the Cybertruck’s range extender from the options in its online configurator.

Does Tesla still plan to bring the product to market?

When Tesla unveiled the production version of the Cybertruck in late 2023, there were two main disappointments: the price and the range.

The tri-motor version, which was the most popular in reservation tallies, was supposed to have over 500 miles of range and start at $70,000.

Tesla now sells the tri-motor Cybertruck for $100,000 and only has a range of 320 miles.

As for the dual-motor Cybertruck, it was supposed to cost $50,000 and have over 300 miles of range. The reality is that it starts at $80,000, and it has 325 miles of range.

However, Tesla had devised a solution to bring the range closer to what it originally announced: a separate battery pack that sits in the truck’s bed. Tesla called it a “range extender.” It costs $16,000 and takes up a third of the Cybertruck’s bed.

Even though the Cybertruck has been in production for a year and a half at this point, the range extender has yet to launch.

Initially, Tesla said that it would come “early 2025”, but we reported that it was pushed to “mid-2025” late last year.

At the time, Tesla also reduced the range that the removable battery pack adds to the Cybertruck to “445+ miles” rather than “470+ miles” for the dual motor – a ~25-mile reduction in range.

Now, Tesla has removed the option from its online Cybertruck configurator. It used to take reservations for the range extender with a “$2,000 non-refundable deposit”, as seen on the image above, but now it’s not in the configurator at all at the time of writing.

It’s unclear if Tesla is not planning to launch the product anymore or if it is just pausing reservations.

In its specs page, Tesla still lists the achievable range of both versions of the Cybertruck with and without the range extender battery:

Electrek’s Take

I’m curious. Is it dead, or does Tesla just want to stop taking reservations for it?

At first, I was curious about the product even though I didn’t think it would make up for Tesla’s significant miss on Cybertruck specs.

However, after it was confirmed that it takes up 30% of your bed and that it needs to be installed and removed by Tesla at a service center, I think it’s pretty much dead on arrival at $16,000.

It’s going to be a product limited to only a few people at best. And now that’s if it makes it to market.

With the option being removed from the configurator, there’s no production timeline available. Again, the last one was “mid-2025”, which is soon.

This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:

In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.

In 2024, the US experienced 27 weather and climate events, each causing losses exceeding $1 billion, marking the second-highest annual total on record, according to National Centers for Environmental Information. The increasing frequency and severity of natural disasters underscore the critical need for reliable and timely power solutions during emergencies, much like EcoFlow and its members are helping provide through the “Power For All” initiative.

To support new and existing EcoFlow members, the company is celebrating its third annual Member’s Festival throughout April to offer a do-not-miss discount on its products and donate a portion of all sales to the “Power for All” fund to provide rescue power to those in need in the future.

Tesla loses another top talent: its long-time head of software

Tesla is losing another top talent: its long-time head of software, David Lau, has reportedly told co-workers that he is exiting the automaker.

Tesla changed how the entire auto industry looks at software.

Before Tesla, it was an afterthought; user interfaces were rudimentary, and you had to go to a dealership to get a software update on your systems.

When Tesla launched the Model S in 2012, it all changed. Your car would get better through software updates like your phone, the large center display was responsive with a UI that actually made sense and was closer to an iPad experience than a car.

Tesla also integrated its software into its retail experience, service, and manufacturing.

David Lau deserves a lot of the credit for that.

He joined Tesla in 2012 as a senior manager of firmware engineering and quickly rose through the ranks. By 2014, he was promoted to director of firmware engineering and system integration, and in 2017, he became Vice President of software.

Lau listed the responsibilities of his team on his LinkedIn:

  • Vehicle Software:
    • Firmware for the powertrain, traction/stability control, HV electronics, battery management, and body control systems
    • UI software and underlying Embedded Linux platforms
    • Navigation and routing
    • iOS and Android Mobile apps
  • Distributed Systems:
    • Server-side software and infrastructure that provides telemetry, diagnostics, over-the-air updates, and configuration/lifecycle management
    • Data engineering and analytics platforms that power technical and business insights for an increasingly diverse set of customers across the company
    • Diagnostic tools and fleet management, Manufacturing and Automation:
  • Automation controls (PLC, robot)
    • Server-side manufacturing execution systems that power all of Tesla’s production operations
  • Product Security and Red Team for software, services, and systems across Tesla

Bloomberg reported today that Lau told his team he is leaving Tesla. The report didn’t include reasons for his stepping down.

Electrek’s Take

Twelve years at any company is a great run. At Tesla, it’s heroic. Congrats, David, on a great run. You undoubtedly had a significant impact on Tesla and software advancements in the broader auto industry.

He is another significant loss for Tesla, which has been losing a lot of top talent following a big wave of layoffs around this time last year.

I wonder who will take over. Michael Rizkalla, senior director of software engineering and vehicle firmware, is one of the most senior software engineers after Lau. He has been at Tesla for 7 years, and Tesla likes to promote within rather than hire outsiders.

There are also a lot of senior software execs working on AI at Tesla. Musk has been favoring them lately and he could fold Lau’s responsibilities under them.
