Houston-based clean energy company Diligence Offshore Services has announced a strategic partnership with Florida-based floating solar manufacturing company AccuSolar for the development of a renewable energy project in the Port Arthur area.

Known as the Pleasure Island Power Collective, it will be built on 2,275 acres across Pleasure Island and Sabine Lake. It is expected to generate 391 megawatts of clean power, alongside a utility-scale battery energy storage system. It will also feature a 225-megawatt coastal onshore wind farm, with energy produced on-site used to power a data center for adaptive superintelligence, making it entirely self-sustained by renewable sources, according to the company.

AccuSolar will design and manufacture the project and power will be distributed through the Canaan Energy Corridor

“We are incredibly proud to partner with a fellow U.S. company like AccuSolar,” Harry C. Crawford III, founder and managing member of Diligence Offshore, said in a news release. “Their expertise in American manufacturing and floating solar technology is essential to the success of the Pleasure Island Power Collective.”

The project is expected to bring economic growth and a significant number of manufacturing jobs to the area during the construction phase and long-term operations.

Diligence Offshore is pursuing a DPA Title 1 DX rating under the Defense Production Act to help advance the project's development schedule, according to the release, which could lead to immediate manufacturing jobs.

“This partnership not only strengthens our domestic supply chain but also accelerates our vision to bring economic freedom and climate resilience to the Gulf Coast,” Crawford added in the release.

$135 million Houston battery storage facility breaks ground

coming soon

SMT Energy and CenterPoint Energy have partnered with utility infrastructure solutions provider Irby Construction Company to break ground on a 160 megawatt battery energy storage system (BESS) located in the Houston zone of the ERCOT market.

“We are proud to be underway and deliver this grid-strengthening project to Houston,” Kevin Midei, SVP of engineering, procurement and construction, at SMT Energy, said in a news release.

The BESS, SMT Houston IV, is expected to support grid stability, deliver fast-response power during peak demands and provide resiliency and renewable integration. The project is expected to be online by 2026 and store and dispatch enough electricity to power 8,800 homes in Texas annually.

SMT Energy is the project owner and developer, and CenterPoint Energy will serve as the interconnecting utility, integrating the system into Houston’s broader electrical network,” according to the companies. Irby Construction will serve as the engineering, procurement, and construction (EPC) contractor, and construction of the project is expected to be completed by July. On May 14, the companies broke ground with a ribbon-cutting ceremony to symbolize the start of the build.

“Projects like this demonstrate how collaboration and forward-thinking infrastructure come together to power a more resilient energy future,” Tony Gardner, SVP and chief customer officer at CenterPoint, said in a news release. “At CenterPoint, we recently completed nearly 90 percent of our overall grid resiliency improvements. This is one more action we are taking to build a more resilient and reliable grid to better serve our customers.”

In March, Colorado-based SMT Energy secured $135 million in funding for the SMT Houston IV, led by Macquarie and KeyBanc Capital Markets as joint lead arrangers. In 2023, SMT Energy and joint venture partner SUSI Partners announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.

In 2019, Irby began construction on the Manatee BESS site with Florida Power and Light (FPL), which was the world’s largest BESS project at the time. Irby has built over 30 BESS sites and has more than 20 currently under construction or contract.

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.”

Other geothermal companies and institutions from around the country will complete the 17 remaining projects. They include:

  • Denver-based 400C Energy Inc.
  • Salt Lake City-based AlterG Resources
  • Denver-based DAVINCI EP LLC
  • Anchorage-based GeoAlaska LLC
  • Oklahoma City-based GreenFire Energy Inc.

CenterPoint gets $50M DOE grant to improve Houston power grid

grid grant

A $50 million federal grant will help Houston-based CenterPoint Energy strengthen Houston’s power grid.

The U.S. Department of Energy (DOE) grant will support power substation upgrades in the Houston area.

“Our mission is to build the most resilient coastal grid in the nation for the 2.9 million customers we proudly serve in the greater Houston area … [The grant] will directly fund industry-leading technology improvements that are expected to strengthen resiliency, reliability, and meet the growing energy needs of our region,” Jason Ryan, CenterPoint Energy’s executive vice president for regulatory services and government affairs, said in a release.

CenterPoint says the project will make it one of the first U.S. utilities to install Siemens Energy’s grid-stabilizing technology.

The project will create more than 500 construction and installation jobs, CenterPoint says.

“Generations of CenterPoint customers and families in the region will benefit from the advanced technology this grant is funding,” said Kathleen Jackson, a member of the Public Utility Commission of Texas. “And any time companies make improvements like this to their systems, the long-term impact is making the entire grid stronger for Texans.”

The $176.7 million substation project is part of CenterPoint’s Greater Houston Resiliency Initiative, which launched in 2024.

So far, the initiative has:

  • Installed nearly 82,400 storm-resilient poles and equipment
  • Trimmed and cleared more than 13,700 miles of trees and vegetation near power lines
  • Added nearly 820 grid automation and intelligence devices
  • Put more than 880 miles of power lines underground

The initiative kicked off three years after Winter Storm Uri. CenterPoint received harsh criticism for what customers complained was the utility’s slow response to the 2021 storm. Uri caused a massive power outage and at least 246 deaths across Texas.

CenterPoint blamed the Electric Reliability Council of Texas (ERCOT), which operates the power grid for most Texans, for not supplying the utility with enough electricity during and after the storm.
