What Good Energy Means

As geothermal grows here,
the region grows with it.

The energy business has a long history of showing up, taking what it came for, and leaving town with it. Good Energy is our answer — a deliberate effort to build local capacity, so that as geothermal development expands across the Borderplex, more of the work, the skills, and the economic benefit stay in the communities that host it.

  • Local hiring, on purposeThe people who pour the concrete, run the wellheads, and keep this site online should come from the Borderplex. We write that priority into scopes early, rather than treating it as a leftover.
  • A clear pathway inLocal contractors and suppliers get a straight line to what's coming — upcoming needs, readiness requirements, and how to engage. Early interest doesn't guarantee a contract, but it puts you in the room while the work is still being defined.
  • It scales as we scaleThis starts with first wells and is built to become repeatable field operations. As it grows, the regional workforce and supplier base grow with it, so the capacity we build now compounds over time.
  • The benefit staysThe power firms up the grid for local industry, data centers, and Fort Bliss, and the return stays with the communities doing the work — instead of leaving town with the rig.

Blacktail Energy and RayGen Execute Strategic Agreement to Advance Multi-Asset Hybrid Power Project in El Paso, TX

Collaboration targets an initial 20–30 MW ORC and 40–50 MW PV Ultra deployment within a contemplated 1,220 MW hybrid energy hub, integrating geothermal, solar, long-duration storage, and natural gas under Blacktail's #GoodEnergy commitment.

EL PASO, Texas — 2026 — As the Borderplex region experiences surging power demand driven by Fort Bliss, residential users, and an emerging data centre corridor, Blacktail Energy Holdings Inc. (“Blacktail”) has executed a strategic Memorandum of Understanding with RayGen Resources Pty Ltd (“RayGen”). The agreement establishes a framework to integrate RayGen's photovoltaic (PV Ultra) and long-duration thermal storage (Thermal Hydro) technologies with Blacktail's power platform at the 4,480-acre Blacktail Acreage in El Paso County, Texas.

The acreage is being developed by Blacktail as a multi-technology hybrid energy hub with a total contemplated generation capacity of approximately 1,220 MW across geothermal, solar, long-duration storage, and natural gas. The site benefits from 4,480 contiguous acres of privately held land, significant geothermal potential, abundant solar viability, existing natural gas pipeline access, and proximity to Fort Bliss and the broader tri-city Borderplex region of over 2.5 million people.

“The Borderplex region requires firm, reliable, and clean energy to support critical defense assets, residential growth, and emerging data centre developments,” said Joe Navar, Chief Executive Officer of Blacktail Energy. “By combining our geothermal development program and Organic Rankine Cycle power generation capabilities with RayGen's PV Ultra and Thermal Hydro storage, we are engineering a differentiated, multi-asset generation asset. Under our #GoodEnergy campaign, we are committed to building infrastructure that strengthens regional power reliability, prioritizes local economic participation, and creates durable value for our community and investors.”
RayGen Chief Executive Officer, Richard Payne, added, “RayGen's PV Ultra and Thermal Hydro technologies were built to deliver dispatchable renewable power wherever the grid needs it most, and the Blacktail Acreage's strong solar resource and position adjacent to growing industrial and urban demand make it an ideal place to demonstrate that value. Blacktail's geothermal and ORC expertise is highly complementary to our storage and generation platform, enabling a unique technical integration between the two systems. We're pleased to be working with a partner as committed to disciplined execution and community benefit as we are, and we look forward to advancing this project toward financial close.”

Under the agreement, a Joint Technical Working Group will examine key integration and shared asset utilization opportunities, including:

  • Domestic ORC Package Supply and Integration: Exploring Blacktail leading the supply and integration of Organic Rankine Cycle (ORC) systems into RayGen's plant at the Blacktail Acreage, leveraging Blacktail's ORC supply chain and integration capabilities.
  • Secondary Heat Re-Use: Utilizing secondary heat from the geothermal resource as a supplemental thermal input to boost overall efficiency for RayGen's integrated power plant.
  • Dual Cold Reservoir Utilisation: Utilizing RayGen's cold reservoir as a temperature sink for Blacktail's wider geothermal resource to improve constancy and operating efficiency.
  • Initial Phased Deployment: Advancing engineering for an anticipated initial RayGen deployment comprising approximately 20–30 MW of ORC capacity and 40–50 MW of PV Ultra capacity, with the potential to scale alongside the broader Hybrid Power Project.

Local Alignment and the #GoodEnergy Standard

Blacktail's #GoodEnergy framework ensures that utility-scale infrastructure development delivers direct, lasting benefits to the host community and regional economy:

  • Regional Economic Participation: Establishing structured visibility into technical and civil scopes to ensure local and regional contractors participate directly in project development.
  • Grid and Mission-Critical Power Security: Providing bulk renewable energy, power firming, and constraint alleviation to support regional industrial growth, data centre development, and Fort Bliss without burdening municipal utility infrastructure.
  • Responsible Resource Development: Leveraging high-efficiency thermal hydro storage and closed-loop geothermal cycles to deliver dispatchable power while respecting regional land and environmental resources.
  • Workforce Mobilization: Creating long-term technical and operational opportunities for the region's skilled mechanical, subsurface, and energy workforce.
“#GoodEnergy means building critical infrastructure with the community and for the community,” added Navar. “Through this partnership, we are accelerating project development toward financial close and construction, providing a clear path to deliver synchronous, high-quality power ahead of schedule.”
