In a landmark move for the energy sector, Utah’s Intermountain Power Project (IPP) is undergoing a transformative upgrade that positions it at the forefront of clean energy innovation. As reported by Engineering News-Record (ENR), the IPP Renewed initiative is a testament to the power of regional cooperation and a bold step toward decarbonizing large-scale power generation through the integration of green hydrogen. As the global energy landscape shifts toward sustainability, this project exemplifies how legacy infrastructure can be reimagined to meet the demands of a low-emissions future.
Environmental Impact and Emissions Reduction
The transition from coal to hydrogen-blended fuel represents a significant environmental milestone. By leveraging green hydrogen – produced through electrolysis powered by renewable energy – the IPP Renewed project aligns with California’s stringent emissions regulations and broader climate objectives.
Hydrogen combustion emits only water vapor, eliminating carbon dioxide and other harmful pollutants associated with fossil fuels. As the technology matures and the hydrogen blend increases, the plant’s emissions profile will continue to improve, setting a new standard for utility-scale power generation.

A Strategic Shift Toward Hydrogen Power
Commissioned in the 1980s, the IPP has long served as an energy hub for communities across six states. With its 1,800-MW coal-fired units nearing the end of their operational life and power purchase agreements set to expire in 2027, stakeholders faced a pivotal decision. Rather than decommission the site, the Intermountain Power Agency (IPA) and its partners chose to invest in a cleaner, more flexible future.
The centerpiece of this transformation is the installation of two advanced M501JAC gas turbines from Mitsubishi Power, capable of operating on a blend of natural gas and hydrogen. To start, the turbines will run on a 30% hydrogen mix, with a roadmap to transition to 100% green hydrogen by 2045. This shift is expected to reduce carbon dioxide emissions by over 75% compared to traditional coal-fired generation.
Leveraging Unique Geology for Energy Storage
One of the most innovative aspects of the IPP Renewed project is its integration with the Advanced Clean Energy Storage (ACES) Delta hub. Located atop a geologic salt dome, the site offers a natural advantage for underground hydrogen storage. Two massive caverns, each capable of holding 4.5 million barrels of hydrogen, will serve as long-term, seasonal energy reservoirs.
This storage capability is crucial for balancing the intermittency of renewable energy sources. Surplus solar and wind power can be converted into green hydrogen via electrolysis and stored until demand peaks. This method enhances grid reliability and enables a more resilient and sustainable energy system.
Engineering Excellence and Workforce Development
The scale and complexity of the IPP Renewed project are immense. With over five million labor hours logged and more than 2,000 workers on-site, the project has become a model for workforce development in the energy sector. The Industrial Company (TIC), serving as the EPC contractor, implemented an on-site training program to certify workers in real-time, accelerating their progression to journeyman status.
In a notable first, TIC also self-performed heavy equipment hauling using self-propelled modular transport units, eliminating reliance on specialty subcontractors and streamlining logistics. This approach underscores the importance of adaptability and innovation in modern infrastructure projects.
Modernizing Transmission for a Clean Energy Future
Beyond generation, the IPP Renewed initiative includes a $2.7-billion overhaul of the Southern Transmission System, which delivers power from Utah to Southern California. This upgrade involves constructing new DC converter stations and enhancing the 2,400-MW transmission capacity to accommodate the evolving energy mix.
The modernization of transmission infrastructure is a critical enabler of the hydrogen economy. It ensures that clean, dispatchable power generated in Utah can be efficiently delivered to demand centers hundreds of miles away, supporting regional decarbonization goals.
The Role of Utility Locating and Leak Detection
As hydrogen infrastructure expands, utility locating and leak detection becomes paramount. Because hydrogen is the smallest and lightest molecule, it can escape through minute leaks that would be inconsequential for other gases. Accurate utility locating ensures that underground pipelines and storage facilities are mapped with accuracy, reducing the risk of accidental damage during construction or maintenance.
Advanced leak detection technologies, including acoustic sensors and leak detection correlators, are essential for maintaining safety and operational integrity.
How GPRS can Support the Future of Clean Energy Infrastructure
GPRS expertise in subsurface infrastructure plays a vital role in supporting projects of this magnitude. As the energy industry embraces hydrogen and other clean technologies, the need for accurate, real-time data on underground utilities and structural conditions becomes increasingly critical.
For complex infrastructure projects like the IPP, GPRS offers support services that enhance safety, accuracy, and efficiency. These include utility locating using ground penetrating radar (GPR) and electromagnetic (EM) locating, advanced leak detection, concrete scanning, 3D laser scanning and mapping to create accurate digital models for design and construction planning, and video pipe inspection to assess the condition of sewer and stormwater systems. Projects involving hydrogen power plants and large-scale energy storage require the highest levels of precision and risk mitigation. GPRS services are indispensable for ensuring safe construction, reliable operations, and long-term infrastructure integrity.
As hydrogen power plants and storage hubs become more prevalent, GPRS stands ready to support these projects with the tools and expertise necessary to ensure safety, efficiency, and regulatory compliance. Our commitment to precision and innovation makes us a trusted partner in the transition to a cleaner, more sustainable energy future.
From hydrogen hubs to high-voltage transmission lines, GPRS Intelligently Visualizes The Built World® to keep your infrastructure projects safe, efficient, and on schedule.

FREQUENTLY ASKED QUESTIONS
Why is utility locating critical for hydrogen infrastructure projects?
Hydrogen facilities require accurate excavation to avoid damaging underground utilities. GPRS uses ground-penetrating radar (GPR) and electromagnetic (EM) locating to identify and map subsurface utilities before construction begins. This helps reduce the risk of utility strikes, supports safe excavation, and ensures compliance with safety regulations.
How does GPRS support leak detection in hydrogen systems?
Hydrogen is colorless, odorless, and highly flammable, which makes early leak detection essential for safety. GPRS’ SIM-certified Project Mangers use acoustic sensors and leak detection correlators to identify leaks in pressurized systems. These technologies help prevent safety incidents, reduce operational downtime, and support compliance with safety standards.
What role does concrete scanning play in hydrogen facility construction?
GPRS can help prevent costly delays and safety risks during hydrogen facility construction by identifying embedded objects before any coring or cutting begins. These objects may include rebar, conduits, and post-tension cables. When locating them in advance, project teams can avoid structural damage and ensure the safe installation of critical systems.
