VoltaGrid, a Bellaire-based startup that specializes in distributed power generation via microgrids, has hauled in $150 million in equity funding.

Founded in 2020, VoltaGrid provides small-scale, self-contained microgrids that can operate independently of major power grids or in tandem with other microgrids. VoltaGrid’s product consists of natural gas engines, portable energy storage, natural gas processing and grid power connectivity.

Investors in the $150 million round include the Canada Pension Plan Investment Board (CPP Investments), Longbow Capital, Walter Ventures, and Pilot Company (operator of more than 800 retail and fueling locations in the U.S. and Canada). The $150 million round comes less than a year after VoltaGrid announced a $100 million round featuring the same investors.

VoltaGrid says it will spend the fresh cash to grow its power generation portfolio, along with its low-carbon fuel program in partnership with Pilot. The low-carbon platform features hydrogen and compressed natural gas.

“VoltaGrid continues to set new milestones across multiple sectors and business lines as we execute on our proven strategy with key partners,” Nathan Ough, president and CEO of VoltaGrid, says in a news release.

“Our strategy to establish one of the largest asset bases of portable generation, uniquely paired with our low-carbon fueling solutions, has significantly decreased the complexity for our partners to electrify their operations. I am thankful to our team members for the tremendous amount of work that has been contributed to create one of the largest portfolios of contracted low carbon fuels in the industry.”

Houston founders aim to provide equity through energy resiliency

Houston innovators podcast episode 143

As temperatures climb and devastating natural disasters continue to test the power grid, two Houston innovators have a solution: Smart microgrids.

"Microgrids have been around for a very long time," Paresh Patel, co-founder of InnoGrid, says on the Houston Innovators Podcast. "We're primed here in Houston and in Texas to really see microgrids go mainstream. ... People want to see that they have control and are in charge of their own power."

Patel co-founded InnoGrid with Ed Pettitt and a few other collaborators following the 2020 Houston Climathon. The social enterprise is working to establish community microgrids in lower income areas — neighborhoods that are most at risk of devastating power outages.

"We want to convert the commercial microgrid model for low and moderate income and undresourced residential communities," Patel explains.

And there's never been a better time to shine a spotlight on microgrids as a solution to unreliable power systems, Pettitt says.

"We're dealing with massive inflation — costs are going up especially in food and energy," he explains on the show. "Even prior to this time of inflation, electricity prices in the US were expected to increase across the board. Hundreds of thousands of people right now today are being pushed below the poverty line because of increased energy costs. We need to be more creative in how we upgrade our infrastructure."

And the current grid system is well overdue for an upgrade. The microgrid system fits right in with the shared economy we live in today, Patel says, and it allows for more generation of energy that is decentralized, digitalized, decarbonized, and democratized — the four Ds as he says.

"When you consider our current grid system, it is a vestige of the industrial revolution — it's 140 years old. That business model is ripe for innovation," Patel says.

"We need to accelerate deployment of microgrid models," he continues. "I don't think we can afford to update our current grid system — it'll cost $2 trillion."

Most importantly, these microgrids need to be implemented in an equitable way, the founders say, and InnoGrid has its eyes on one Houston area in particular. The Innovation Corridor, which spans from the Texas Medical Center to Downtown Houston, would be the ideal region to deploy the technology.

"If you look at the innovation corridor, it forms the spine of the city. You have so many important municipal buildings, first-responding organizations, and a large amount of affordable housing in the area. There's critical resources here that we want to make sure the lights stay on in power disasters," Pettit says. "One of the things we believe at InnoGrid is that where you live shouldn't determine whether or not you survive a national weather event. We want to make sure we provide energy stability in the communities that need it most."

To make this dream into a reality, InnoGrid needs the right partnerships and support in the area — and the founders have made progress. InnoGrid recently participated in the Ion Smart and Resilient Cities Accelerator and has a relationship with Greentown Houston across the street.

Eventually, as Pettit says, InnoGrid wants to help lead Houston to becoming a hub for microgrid innovation.

"We're looking at other cities — like Chicago and Boston — and how they've deployed their microgrids and making sure we're bringing those best practices in Houston," Pettit says. "Eventually we want to be the leader in developing these microgrid best practices as the energy capital of the world."

TMC, Memorial Hermann launch partnership to spur new patient care technologies

medtech partnership

Texas Medical Center and Memorial Hermann Health System have launched a new collaboration for developing patient care technology.

Through the partnership, Memorial Hermann employees and physicians will now be able to participate in the TMC Center for Device Innovation (CDI), which will assist them in translating product innovation ideas into working prototypes. The first group of entrepreneurs will pitch their innovations in early 2026, according to a release from TMC.

“Memorial Hermann is excited to launch this new partnership with the TMC CDI,” Ini Ekiko Thomas, vice president of information technology at Memorial Hermann, said in the news release. “As we continue to grow (a) culture of innovation, we look forward to supporting our employees, affiliated physicians and providers in new ways.”

Mentors from Memorial Hermann, TMC Innovation and industry experts with specialties in medicine, regulatory strategy, reimbursement planning and investor readiness will assist with the program. The innovators will also gain access to support systems like product innovation and translation strategy, get dedicated engineering and machinist resources and personal workbench space at the CDI.

“The prototyping facilities and opportunities at TMC are world-class and globally recognized, attracting innovators from around the world to advance their technologies,” Tom Luby, chief innovation officer at TMC Innovation Factor, said in the release.

Memorial Hermann says the partnership will support its innovation hub’s “pilot and scale approach” and hopes that it will extend the hub’s impact in “supporting researchers, clinicians and staff in developing patentable, commercially viable products.”

“We are excited to expand our partnership with Memorial Hermann and open the doors of our Center for Device Innovation to their employees and physicians—already among the best in medical care,” Luby added in the release. “We look forward to seeing what they accomplish next, utilizing our labs and gaining insights from top leaders across our campus.”

Google to invest $40 billion in AI data centers in Texas

Google is investing a huge chunk of money in Texas: According to a release, the company will invest $40 billion on cloud and artificial intelligence (AI) infrastructure, with the development of new data centers in Armstrong and Haskell counties.

The company announced its intentions at a meeting on November 14 attended by federal, state, and local leaders including Gov. Greg Abbott who called it "a Texas-sized investment."

Google will open two new data center campuses in Haskell County and a data center campus in Armstrong County.

Additionally, the first building at the company’s Red Oak campus in Ellis County is now operational. Google is continuing to invest in its existing Midlothian campus and Dallas cloud region, which are part of the company’s global network of 42 cloud regions that deliver high-performance, low-latency services that businesses and organizations use to build and scale their own AI-powered solutions.

Energy demands

Google is committed to responsibly growing its infrastructure by bringing new energy resources onto the grid, paying for costs associated with its operations, and supporting community energy efficiency initiatives.

One of the new Haskell data centers will be co-located with — or built directly alongside — a new solar and battery energy storage plant, creating the first industrial park to be developed through Google’s partnership with Intersect and TPG Rise Climate announced last year.

Google has contracted to add more than 6,200 megawatts (MW) of net new energy generation and capacity to the Texas electricity grid through power purchase agreements (PPAs) with energy developers such as AES Corporation, Enel North America, Intersect, Clearway, ENGIE, SB Energy, Ørsted, and X-Elio.

Water demands

Google’s three new facilities in Armstrong and Haskell counties will use air-cooling technology, limiting water use to site operations like kitchens. The company is also contributing $2.6 million to help Texas Water Trade create and enhance up to 1,000 acres of wetlands along the Trinity-San Jacinto Estuary. Google is also sponsoring a regenerative agriculture program with Indigo Ag in the Dallas-Fort Worth area and an irrigation efficiency project with N-Drip in the Texas High Plains.

In addition to the data centers, Google is committing $7 million in grants to support AI-related initiatives in healthcare, energy, and education across the state. This includes helping CareMessage enhance rural healthcare access; enabling the University of Texas at Austin and Texas Tech University to address energy challenges that will arise with AI, and expanding AI training for Texas educators and students through support to Houston City College.
