The Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named Houston venture capital and innovation leader Sandy Guitar as its new executive director.

Guitar succeeds David Pruner, who will move into the board chair role.

Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital. She also sits on the advisory board of Rice University's Liu Idea Lab for Innovation and Entrepreneurship (Lilie) and launched the Women Investing in VC in Houston group.

In a LinkedIn post, Guitar shared that she's looking forward to bringing her problem-solving skills to the energy transition.

"Innovating in the energy sector is as significant and intricate a problem as I have ever worked on — one that demands creativity, collaboration, and resourcefulness at every turn," she shared.

"I'm honored to join TEX-E at such a pivotal time in the energy transition," she added in a news release. "Energy and climate innovation is accelerating at the intersection of brilliant minds and bold ideas. I'm excited to help TEX-E amplify that collision between students who think differently and the real-world problems that demand fresh solutions."

According to TEX-E, Guitar will continue to lead the organization's programming that aims to connect student climate entrepreneurs with "industry reality."

"Sandy understands the complexities of the Texas energy ecosystem and brings a forward-looking vision for how related innovation can drive meaningful, lasting impact. She's exactly the leader we need to take TEX-E to the next level and help create the next generation of energy transition innovators," David Baldwin, TEX-E board member, added in the release.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

It's known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek, which awarded $25,000 to HEXASpec, a Rice University-led team, at the 2025 event. It also hosted its inaugural TEX-E Conference, centered on the theme of Energy & Entrepreneurship: Navigating the Future of Climate Tech, earlier this year.

Why this organization is focused on cultivating the future of energy transition innovation

Q&A

"Our mission is to create the next generation of energy transition climatetech entrepreneurs and intrapreneurs — they don’t all have to start companies," he says on the Houston Innovators Podcast.

Listen to the show below and read through a brief excerpt from the episode with Pruner.

EnergyCapital: Can you share a little bit about the origin of TEX-E?

David Puner: There were a variety of factories that led to its creation, but the seminal event was a piece of work that had been done for the Greater Houston Partnership by McKinsey on the future of Houston. It showed that if Houston isn't careful and doesn't make sure to go ahead and transition with this energy expansion we’re seeing, that they’re at risk of losing hundreds of thousands of jobs. If they catch the transition right and make the conversion to cleaner and low-carbon fuels, they can actually gain 1.4 million jobs.

It was this eye opener for everyone that we need to make sure that if the energy transition is going to happen, it needs to happen here so that Houston stays the energy capital of the world.

David Baldwin (partner at SCF Partners) literally at the meeting said, “listen I've got the beginning of the funnel — the universities, that’s where innovation comes from.” From that, TEX-E was born.

EC: How are you working with the five founding universities to connect the dots for collaboration?

DP: In the end, we have five different family members who need to be coordinated differently. The idea behind TEX-E is that there's plenty of bright students at each of these schools, and there's plenty of innovation going on, it's whether it can grow, prosper, and be sustainable.

Our main job is to look to connect everyone, so that an engineer at Texas A&M that has an idea that they want to pursue, but they don't know the business side, can meet that Rice MBA. Then, when they realize it's going to be a highly regulated product, we need a regulatory lawyer at UT — we can make all that happen and connect them.

At the same time, what we found is, no one school has the answer. But when you put them together, we do have most of the answer. Almost everything we need is within those five schools. And it's not just those five schools, it really is open to everyone.

EC: As you mentioned before, TEX-E started as a way for Houston to take the reins of its energy transition. What's the pulse on that progress?

DP: I spent the last decade building boards and hiring CEOs for all kinds of energy companies and there was the period I would say — pre-pandemic and a little bit into the pandemic — where not everybody was on board with climate change and the issue of carbon. The nice thing now is that’s fully in the rearview mirror. There’s not really a company of any size or a management team of any major entity that doesn’t fully believe they need to do something there.

The train has fully left the station — and picked up speed — on this whole issue of transition and climate. So, that’s been nice to see and create a lot of tailwinds.

Houston geothermal company picks Nevada site for commercial-scale project

coming soon

Sage Geosystems, a Houston-based developer of geothermal power systems, has chosen a site in Nevada for its commercial-scale Project Vector facility.

The company’s two-well enhanced geothermal system (EGS) will deliver around-the-clock geothermal heat to Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada.

The startup expects to begin drilling the first well later this year, with the first electricity to be generated in 2027 and full-scale production to start in 2028.

In the Nevada system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock and return heat to the surface. The heat will be delivered to the Blue Mountain plant for conversion into electricity.

Project Vector builds on the performance of Sage’s SMECI facility in South Texas. That facility’s results, combined with Sage’s digital twin platform, will be used to shape to the design and development of Project Vector.

Project Vector supports Sage’s growing commercial pipeline, including a 150-megawatt geothermal power agreement with Meta Platforms, the parent company of Facebook and Instagram.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” Jason Peart, chief operating officer at Sage, said in a release. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector extends Sage’s relationship with Ormat.

In August 2025, Sage and Ormat agreed to accelerate commercialization of Sage’s geothermal technology at an Ormat power plant. This January, Ormat co-led Sage’s $97 million Series B funding round.

Sage, founded in 2020, has raised about $159 million across three funding rounds.

As the startup ramps up its ESG platform, Sage is targeting data centers as customers, among other large-scale users of electricity.

“The energy needs are huge, and they need it now,” CEO Cindy Taff said on Data Center Frontiers’ podcast. “They can’t depend on the grid anymore.”

Houston’s power advantage: Key takeaways from 2026 HETI Power Summit

The view from heti

Power has become a defining economic development issue as electricity demand rises across Texas.

Industrial expansion, advanced manufacturing, AI and data center growth are increasing the importance of reliable, affordable power delivered on the timelines major projects require.

The 2026 HETI Power Summit, titled Houston’s Power Advantage: Competing for Large-Load Growth, brought together leaders from utilities, power producers, large energy customers, technology and infrastructure providers, professional services firms and the public sector to examine how Houston can meet this moment.

Across keynotes, research report-outs, panel discussions and a fireside chat, a consistent theme emerged: Houston’s power advantage comes from the region’s ability to align utilities, customers, infrastructure, flexible demand, emerging solutions and regional partners around reliable, affordable and timely growth.

Reliability and Readiness

Public Utility Commission of Texas Commissioner Kathleen Jackson opened the summit by emphasizing reliability as the foundation for continued growth as Texas electricity demand rises.

Commissioner Jackson underscored the importance of sustained planning and investment to support new industrial, manufacturing and digital demand while maintaining a reliable power system. Remarks framed the morning’s broader discussion of how Houston can pair reliability with speed, affordability and long-term system readiness.

Scott Cockerham of FTI Consulting previewed HETI and FTI’s “Texas Power Market & Industry Assessment”. The research identifies accessibility, reliability, affordability, market flexibility and infrastructure readiness as key dimensions of regional competitiveness.

Leaders from FTI Consulting, Kroll, AWS and Constellation also discussed factors shaping major investment decisions, including reliability, infrastructure timelines, cost certainty, site readiness, community support and regional coordination.

For large customers, these factors must translate into credible project-level execution. Confidence in system performance, energization timelines and infrastructure plans can materially influence major capital commitments.

Building for the Houston We Want to Become

Jason Ryan of CenterPoint Energy challenged participants to plan now for the infrastructure needed to support Houston’s next phase of growth. Drawing on the idea that “what got you here won’t get you there,” Ryan urged the region to build infrastructure for “the Houston we want to become” and stay ahead of large-load demand.

A fireside discussion between CenterPoint Energy and Foxconn brought that challenge to the customer level. The conversation explored how early coordination between utilities and large customers can help advanced manufacturing projects move from site selection and planning to construction and operation.

Long-term growth will require continued investment in generation, transmission and distribution. In the near term, better use of existing infrastructure can create additional capacity.

HETI also shared findings from its Role of Efficiency & Demand Response to Meet Near-Term Regional Power Demand report. Energy efficiency can lower baseline electricity use, while demand response can shift or reduce demand during critical periods. Combined with supply-side investment, these tools can create grid headroom as longer-term infrastructure advances.

The summit’s closing panel, featuring leaders from Amperon, Enchanted Rock, EY and Quanta Services, expanded the discussion to emerging solutions. Panelists explored modular and flexible generation, advanced forecasting, grid intelligence and greater coordination among utilities, customers, infrastructure providers and communities.

Houston’s broader regional power landscape adds another dimension. Entergy Texas President and CEO Eli Viamontes described Southeast Texas as experiencing an “extraordinary trifecta of residential, industrial and data center growth.” His remarks highlighted how the MISO-facing portion of the region complements Houston’s ERCOT strengths through utility planning, generation and infrastructure investment, resource adequacy and coordination with major industrial customers.

Together, these approaches point to a broader strategy: invest for long-term demand while using flexibility, technology and regional coordination to create capacity for growth today.

From Power Advantage to Economic Advantage

Taken together, the Power Summit discussions point to a clear priority for Houston: translating power market and infrastructure strengths into coordinated execution.

Priority areas include earlier infrastructure planning, stronger site and project readiness, clearer pathways from projected demand to reliably served load, expanded efficiency and flexibility, and sustained coordination among utilities, customers, policymakers, communities, technology providers and economic development organizations.

HETI is advancing this work through research and convening efforts focused on Houston’s evolving power needs and economic competitiveness.

The 2026 Power Summit reinforced Houston’s strong foundation for power-intensive growth and the importance of aligning investment, reliability, flexibility and regional coordination around the next generation of economic opportunity.

Houston geothermal companies secure more than $45M in DOE funding

geothermal boost

Three Houston-based companies—Fervo Energy, Quaise Energy and XGS Energy—have been selected by the U.S. Department of Energy to advance geothermal technologies and field tests.

Combined, the companies will receive more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative. The projects were among 21 selected from around the country to receive a total of $99 million.

Fervo was selected to conduct two projects under the initiative for approximately $20 million in funding. For the first project, the geothermal unicorn, which achieved first power at its flagship geothermal plant last week, will drill and complete enhanced geothermal systems (EGS) wells in Elmore County, Idaho, and will deploy high-temperature seismic monitoring technology at record-high temperatures at or above 200°C.

For the second project, the company will conduct an appraisal drilling campaign at a "high-priority" site in Humboldt County, Nevada, to confirm if the reservoir is suitable for EGS development.

“We are grateful to the Department of Energy for funding these grants. We believe this is a clear indication from the federal government that expanding geothermal energy to new states is a national priority,” Jack Norbeck, CTO and co-founder of Fervo Energy, said in a news release. “We expect this funding to accelerate Fervo’s pipeline and advance the cutting edge of geothermal technologies.”

Fresh off a $180 million Series B, Quaise Energy also received $25 million in DOE funding through the initiative to support its Project Obsidian super hot geothermal plant in Central Oregon. The funding will go toward the analysis of the drilling, stimulation and flow results of the first two wells at the Project Obsidian site, which will help the company optimize its third well on site.

“This DOE support is a recognition of what we are building at Quaise and the progress we are making in the field, including the confirmation well currently being drilled at Project Obsidian,” Carlos Araque, CEO and president of Quaise, said in a release. “Our ambition has always been to make superhot geothermal a commercial reality, and Project Obsidian is where we first deliver on that promise.”

XGS Energy, which recently relocated its headquarters from Palo Alto, California, to Houston, was also selected for an exploration drilling project. The company will drill a deep vertical appraisal well in Socorro County, New Mexico, to determine if the site is a viable source of geothermal energy. XGS had not disclosed a funding estimate at press time.

The full value of the proposed DOE funding is subject to completion of award negotiations, according to Quaise.

Data from these projects will be shared through DOE’s Geothermal Data Repository (GDR), providing valuable information to researchers and stakeholders in the geothermal sector.

“This is an excellent example of how public and private entities can partner together to scale critical energy technologies,” Tim Latimer, CEO and co-founder of Fervo, added in a release. “With this funding, the Department of Energy is making important investments to help Americans across the country gain access to clean, affordable geothermal energy.”
