Given Detailed Analysis, Grids Can Host The Most Solar
Originally published at ILSR.org
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affordable solar energy, but to get it to them, solar developers must navigate the impediments of a congested and outdated electricity grid.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.

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.

First Solar just cut the ribbon on a huge new factory in Iberia Parish, Louisiana, and it dwarfs the New Orleans Superdome. The company’s $1.1 billion, fully vertically integrated facility spans 2.4 million square feet, or about 11 times the size of the stadium’s main arena.
The factory began production quietly in July, a few months ahead of schedule, and employs more than 700 people. First Solar expects that number to hit 826 by the end of the year. Once it’s fully online, the site will add 3.5 GW of annual manufacturing capacity. That brings the company’s total US footprint to 14 GW in 2026 and 17.7 GW in 2027, when its newly announced South Carolina plant is anticipated to come online.
The Louisiana plant produces First Solar’s Series 7 modules using US-made materials — glass from Illinois and Ohio, and steel from Mississippi, which is fabricated into backrails in Louisiana.
The new factory leans heavily on AI, from computer vision that spots defects on the line to deep learning tools that help technicians make real‑time adjustments.
Louisiana Governor Jeff Landry says the investment is already a win for the region, bringing in “hundreds of good-paying jobs and new opportunities for Louisiana workers and businesses.” A new economic impact analysis from the University of Louisiana at Lafayette projects that the factory will boost Iberia Parish’s GDP by 4.4% in its first full year at capacity. The average manufacturing compensation package comes in at around $90,000, more than triple the parish’s per capita income.
First Solar CEO Mark Widmar framed the new facility as a major step for US clean energy manufacturing: “By competitively producing energy technology in America with American materials, while creating American jobs, we’re demonstrating that US reindustrialization isn’t just a thesis, it’s an operating reality.”
This site joins what’s already the largest solar manufacturing and R&D footprint in the Western Hemisphere: three factories in Ohio, one in Alabama, and R&D centers in Ohio and California. Just last week, First Solar announced a new production line in Gaffney, South Carolina, to onshore more Series 6 module work. By the end of 2026, the company expects to directly employ more than 5,500 people across the US.

No, it’s not the new Bolt. GM’s design team previewed a new high-riding “sporty Chevrolet EV” that should be brought to life.
Is Chevy launching a new sporty EV?
This is the all-electric vehicle Chevy should sell in the US. General Motors’ design team released a series of sketches previewing a sporty new Chevy EV.
Although it kinda looks like the new 2027 Chevy Bolt EV as a higher-sitting compact crossover SUV, the design offers a fresh take on what it should have looked like.
The new Bolt is essentially a modernized version of the outgoing EUV model with a similar compact crossover silhouette. Nissan adopted a similar style with the new 2026 LEAF as buyers continue shifting from smaller sedans and hatchbacks to crossovers and SUVs.
Will we see the sporty Chevy EV in real life? It’s not likely. For one, the “exploration sketch” is by GM China Advanced designer Charles Huang.
GM Design posted the sketches on its global social media page, but the caption read “Sporty Chevrolet EV for the China Market.”
It’s too bad. The Bolt could use a sporty sibling like an SS variant. Chevy introduced the Blazer EV SS (check out our review) for the 2026 model year, its fastest “SS” model yet. Packing up to 615 horsepower and 650 lb-ft of torque, the Chevy Blazer SS can race from 0 to 60 mph in 3.4 seconds when using Wide Open Watts (WOW) mode.
Will the Bolt be next? I wouldn’t get my hopes up. And if GM does bring the sporty Chevy EV to life, it will likely only be sold in China. Like all the fun cars these days.
What do you think of the design? Would you buy one of these in the US? Let us know your thoughts in the comments.
While deliveries of the 2027 Bolt are set to begin in early 2026, Chevy is offering some sweet deals on its current EV lineup, including up to $4,000 off in Customer Cash and 0% APR financing for 60 months.
