Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition: a roundup of events not to miss, what to expect from the eclipse, and more.

Eyes on ERCOT amid eclipse

For three hours today, Texas' solar energy market will be affected by the solar eclipse. According to a report from the Environment Texas Research & Policy Center, Texas ranks third in the U.S. for residential solar power generation, so the moon's interception to the sunlight can be a real test to ERCOT, which reported that they have worked with solar forecast vendors on what to expect from solar generation on the grid during the eclipse.

"As we did in preparation for the October 2023 eclipse, ERCOT is actively monitoring the forecasts and available dispatchable capacity for April 8," reads a statement from the organization's March report. "ERCOT will rely on Ancillary Services and other actions to posture the system as necessary during the eclipse to compensate for both the reduction and increase in solar generation on this day and maintain grid reliability. ERCOT has been engaging Market Participants so that they are prepared for the eclipse and expects sufficient generation to meet demand."

Really big deal: Shell's EV charging plans

As it downshifts sales of fuel for traditional vehicles, energy giant Shell is stepping up its commitment to public charging stations for electric vehicles.

In a new report on energy transition, Shells lays out an aggressive plan for growing its public network of charging stations for electric vehicles (EVs). The company plans to boost the global number of public EV charging stations from about 54,000 today to around 70,000 by 2025 and about 200,000 by 2030.

The projected growth from today to 2030 would represent a 270 percent increase in the number of Shell-operated EV charging stations.

“We have a major competitive advantage in terms of locations, as our global network of service stations is one of the largest in the world,” Shell says in the report. Read the full story.

Houston energy company to invest $1B in U.S. electric grid manufacturing

grid boost

Hitachi Energy, whose U.S. headquarters is in Houston, has earmarked more than $1 billion to manufacture infrastructure for the U.S. electric grid, which is coping with greater power demand from data centers and AI platforms.

Of that sum, $457 million is dedicated to building a power transformer factory in Virginia. Hitachi Energy said it’ll be the largest facility of its kind in the U.S.

“Power transformers are a linchpin technology for a robust and reliable electric grid and winning the AI race. Bringing production of large power transformers to the U.S. is critical to building a strong domestic supply chain for the U.S. economy and reducing production bottlenecks, which is essential as demand for these transformers across the economy is surging,” said Andreas Schierenbeck, CEO of Switzerland-based Hitachi Energy, which generates revenue of about $16 billion.

The Hitachi announcement aligns with various priorities of the Trump administration. The White House is promoting more U.S.-based manufacturing, more power to accommodate data centers and AI, and greater use of U.S. energy resources.

“If we are going to win the AI race, reindustrialize, and keep the lights on, America is going to need a lot more reliable energy,” U.S. Energy Secretary Chris Wright said.

Texas still has its best solar days ahead of it, even as federal tax credit sunsets

Guest Column

If you follow energy policy, you already know that Congress repealed the 30% residential solar tax credit. This poses a significant challenge for continued growth in the market. It also provides an opportunity for the industry to grow in a smart, consumer-friendly way. That’s why in Texas, the story is what happens next: The state and the market are continuing to make going solar much simpler, better, and cheaper.

Policies are moving in the right direction. For example, starting this month, a bipartisan permitting reform takes effect that will cut red tape for home solar and batteries. It lets licensed third-party professionals review plans and perform inspections, requires agencies to post standardized rules and fees online, and allows homeowners to start work once those third-party approvals are submitted. It also shifts negligence liability to the third-party reviewer, thereby reducing municipal risk while accelerating safe, code-compliant installs. In plain English: fewer bottlenecks, faster installs, and lower “soft costs.”

As a result, Houston is already piloting the National Renewable Energy Lab’s free SolarAPP+ to auto-approve standard solar designs, which cuts roughly 12 days from typical timelines. Independent analyses estimate that these automated permitting rules could trim rooftop solar costs by thousands. In other words, even small, costless policy changes like this can save you almost as much money as the huge solar tax credit did, and these great reforms are happening all the time, and they make the process much more convenient and reliable.

While Texas is making solar simpler, it’s also helping consumers have a good experience when going solar. As of this month, Texas law now also requires solar salespeople to register with the Texas Department of Licensing and Regulation. The same bill standardizes contracts and provides for mandatory disclosures of upfront cost and financing terms. The whole solar industry benefits when customers have a good solar experience. Word of mouth is vital to keeping solar shining.

There's yet another pro-solar Texas law that's also going into effect this month: in addition to SB 1202 (streamlining solar permits) and SB 1036 (regulating solar sales tactics), the legislature is also supporting the dissemination of information about your options when going solar via SB 1697. You can read more about these three brand-new pro-solar state laws here.

The end of the solar tax credit is not the end of the solar industry. Far from it.

Sunnova assets officially sold as founder launches new Houston energy startup

solar shift

Solaris Assets has completed its acquisition of the majority of Sunnova Energy International’s residential solar assets. Houston-based Sunnova filed for Chapter 11 bankruptcy this summer after piling up billions of dollars in debt.

Meanwhile, Sunnova founder and former CEO John Berger has launched a Houston-based home energy services startup, Otovo USA, which just received more than $4 million in seed funding.

Solaris now owns Sunnova’s residential solar services platform and its solar generation and storage portfolio, along with leases, loans and power purchase agreements. Sunnova’s operations are being shifted to SunStrong Management, an Austin-based asset manager for the renewable energy sector.

“By bringing together SunStrong’s asset management expertise with Sunnova’s nationally scaled customer base, we are creating a stronger, more capable leader in the solar industry,” Brendon Merkley, CEO of SunStrong, said in a news release. “Our priority is to maintain the highest levels of service for customers as we expand our footprint as a premier solar asset servicer.”

In June, Sunnova sold its new-home business to homebuilder Lennar for $15.2 million and sold certain assets to investment firm Atlas SP Partners for $15 million.

As of December, Sunnova’s debt totaled nearly $10.7 billion, Reuters reported. Sunnova faced numerous challenges in its quest to survive, including higher interest rates, the reduction of solar incentives in California, and a shakeup in federal subsidies for renewable energy.

Sunnova filed for Chapter 11 bankruptcy in June. A month later, a bankruptcy judge approved the court-supervised sale of Sunnova. Solaris’ acquisition of Sunnova closed Sept. 3.

As SunStrong absorbs the bulk of Sunnova’s assets, Berger — who quit in March as Sunnova’s CEO — has formed a new business. He’s now the founder and CEO of Otovo USA, a partner of European residential power company Otovo.

Otovo USA offers solar power systems, solar batteries, standby generators, EV chargers, electric-load managers, and other power generation and management systems. Otovo’s AI-supported offerings are now available in Texas; the company plans to expand nationwide.

Otovo USA raised its seed funding from the EIC Rose Rock Venture Fund, which invests in energy startups.

“Otovo USA is here to help the millions of Americans with home energy services that are fed up with the complexities of warranties, juggling multiple vendors, and long repair times,” Berger said. The startup, he added, “is bringing customers what they really need: reliable power and a single partner accountable for keeping it up and running. It’s your power, backed by ours.”
