Glendale Water & Power’s Intermountain Power Project (IPP) agreement has transitioned to a 100% coal-free energy resource, currently operating on natural gas while preparing for future hydrogen use, the California public power utility said in December.
The plant is located near Delta, Utah and operated under the supervision of Los Angeles Department of Water & Power.
“This major change lowers portfolio emissions, reduces long-term carbon-compliance costs, and better aligns Glendale with California’s decarbonization requirements, while strengthening reliability and supporting cleaner, more resilient energy utilization,” GWP said.
The city is focusing on a hydrogen-ready future, securing long-term access to a unit designed to gradually increase its blend of clean hydrogen. This positions Glendale to participate in the regional shift from natural gas to hydrogen as the technology becomes viable, the utility said.
“For the first time, our power portfolio contains no coal-fueled energy resources, a significant milestone in our long-term commitment to sustainability and a cleaner energy future for our community. This achievement keeps us firmly aligned with the City Council’s goal of reaching 100% clean energy by 2035,” said Scott Mellon, General Manager of GWP.
The renewed IPP agreement “offers a strong value proposition: it supports near-zero-carbon operations, helps Glendale meet future regulatory mandates, reduces dependence on buying carbon credits, and improves long-term cost stability by lowering exposure to carbon-related risks,” GWP said.
“Glendale’s transition to a 100% coal-free power supply marks a major step forward in our commitment to a cleaner, healthier, and more resilient future for our community. By establishing reliable hydrogen supply, we’re ensuring that Glendale remains at the forefront of innovation and reflects our dedication to delivering responsible, forward thinking energy solutions,” said Mayor Ara Najarian.
To reach this goal, GWP has completed extensive steps, including:
• Early feasibility discussions on hydrogen conversion.
• Reviewing engineering studies, timelines, and operational impacts.
• Conducting internal modeling to ensure alignment with SB100 and future grid utilization.
• Evaluating reliability impacts during the transition away from fossil fuels.
• Working with partners to refine the agreement and clarify hydrogen-conversion responsibilities.
• Providing ongoing updates to leadership to keep the city aligned with long-term clean energy goals.
